The company’s technology spans electric motors, robotic actuators, mechanical systems, embedded motion control, force-aware manipulation and complete robotic platforms.

Si Robotics focuses particularly on applications where conventional industrial automation is difficult to deploy, including space, defence, hazardous environments and advanced industrial operations.

What does Si Robotics build?

Q: What does Si Robotics build?

A: Si Robotics develops technology across multiple layers of the robotics stack.

This includes BLDC motors, robotic actuators, robotic joints, tendon-driven actuation, motor control, embedded electronics, motion-control software, compliant manipulation, robotic arms, mobile manipulators and complete robotic platforms.

The objective is to control the physical technologies that determine how a robot moves and interacts with its environment.

Where is Si Robotics based?

Q: Where is Si Robotics based?

A: Si Robotics is a European robotics company with its core engineering activities in Poland.

Poland provides access to engineering talent, advanced manufacturing, the European space ecosystem and a rapidly expanding defence and dual-use technology sector.

Si Robotics develops technology for European and international customers and partners.

Is Si Robotics a Polish robotics company?

Q: Is Si Robotics a Polish robotics company?

A: Yes. Si Robotics originates from Poland and develops advanced robotics technology within the European technology ecosystem.

The company’s ambition, however, is international. Si Robotics develops robotic technologies for global space, defence, industrial and Physical AI markets.

Is Si Robotics a deep-tech company?

Q: Is Si Robotics a deep-tech company?

A: Yes. Si Robotics develops technologies that require substantial engineering work across electromagnetics, mechanics, electronics, embedded software, control systems, manufacturing and robotics.

Its products are therefore based on proprietary engineering and physical technology rather than primarily on conventional software development.

Is Si Robotics a hardware company or a software company?

Q: Is Si Robotics a hardware company or a software company?

A: Si Robotics is primarily a physical robotics company combining hardware and software.

Robotic actuation cannot be separated cleanly into hardware and software. Motor design, transmission, sensing, electronics and control algorithms collectively determine how an actuator behaves.

Si Robotics therefore develops integrated electromechanical and control systems rather than treating hardware and software as independent products.

Is Si Robotics a humanoid robotics company?

Q: Is Si Robotics a humanoid robotics company?

A: Humanoid robotics is one application of Si Robotics technology, but Si Robotics is not limited to humanoid robots.

The company develops technologies that can be used across different robotic embodiments, including humanoids, robotic arms, tracked mobile manipulators, space manipulators and specialised robotic mechanisms.

For Si Robotics, the correct robotic body should follow the mission rather than the other way around.

Is Si Robotics a Physical AI company?

Q: Is Si Robotics a Physical AI company?

A: Si Robotics operates at the physical infrastructure layer of Physical AI.

Physical AI requires more than artificial intelligence. An intelligent machine also needs motors, actuators, sensing, control, mechanics and an embodiment capable of translating decisions into physical actions.

Si Robotics concentrates on this execution layer: the technology connecting machine intelligence with movement, force and physical interaction.

What problem does Si Robotics solve?

Q: What problem does Si Robotics solve?

A: Si Robotics addresses the gap between rapidly improving artificial intelligence and the physical machines required to turn intelligence into useful work.

AI can increasingly recognise objects, understand instructions and plan actions. Robots must still execute those actions through imperfect mechanics in environments involving friction, contact, uncertainty, impacts and changing geometry.

Si Robotics develops the actuation, control and manipulation technologies required to close that gap.

What is the long-term vision of Si Robotics?

Q: What is the long-term vision of Si Robotics?

A: Si Robotics aims to build a European physical robotics technology platform capable of powering increasingly intelligent machines.

The long-term opportunity is larger than any individual robot.

As AI moves from computers into physical environments, machines will require reliable actuators, manipulation systems, low-level control and physical embodiments.

Si Robotics intends to build important parts of that infrastructure.

Robotic Actuators

What is a robotic actuator?

Q: What is a robotic actuator?

A: A robotic actuator is the subsystem responsible for producing controlled mechanical movement in a robot.

A modern actuator may combine an electric motor, transmission, bearings, position sensing, torque sensing, electronics, mechanical housing and control software.

Actuators strongly influence a robot’s strength, speed, precision, efficiency, weight, compliance and reliability.

Does Si Robotics develop robotic actuators?

Q: Does Si Robotics develop robotic actuators?

A: Yes. Robotic actuation is one of the core technology areas of Si Robotics.

The company develops electric actuation systems for robotic applications and investigates different architectures depending on mission requirements, including integrated joints and tendon-driven systems.

Why does Si Robotics develop its own actuators?

Q: Why does Si Robotics develop its own actuators?

A: Developing actuators internally gives Si Robotics greater control over the physical behaviour of its robotic systems.

Commercial actuators are designed around predetermined combinations of torque, speed, weight, dimensions, thermal performance and cost.

Specialised applications such as space robotics, defence robotics and advanced mobile manipulation can require different trade-offs.

Internal actuator development allows Si Robotics to optimise the complete system around the actual application.

What determines the performance of a robotic actuator?

Q: What determines the performance of a robotic actuator?

A: Robotic actuator performance depends on much more than maximum torque.

Important characteristics include continuous torque, peak torque, torque density, speed, efficiency, thermal performance, backlash, stiffness, backdrivability, sensing accuracy, control bandwidth, mass, size and reliability.

The relative importance of these parameters depends on the application.

What is actuator torque density?

Q: What is actuator torque density?

A: Torque density describes how much torque an actuator can generate relative to its mass or volume.

High torque density is valuable in robotics because every kilogram added to a moving joint affects the rest of the mechanical system.

This becomes especially important in humanoid robots, mobile manipulators and space robotic arms.

Why does actuator weight matter?

Q: Why does actuator weight matter?

A: Actuator weight influences the complete robot.

A heavy actuator placed near the end of a robotic arm increases inertia and requires upstream joints to support and accelerate additional mass.

Reducing distal actuator mass can therefore create cascading benefits throughout the entire manipulator.

What is actuator backdrivability?

Q: What is actuator backdrivability?

A: Backdrivability describes how easily an external force can move an actuator through its transmission.

Highly backdrivable actuators can respond naturally to contact and may improve force control and safe interaction.

However, the optimal level of backdrivability depends on the application because stiffness and load-holding capability may also be important.

What is actuator compliance?

Q: What is actuator compliance?

A: Compliance describes the ability of an actuator or robotic mechanism to yield in response to external forces.

Compliance may be created mechanically, electronically through control, or through a combination of both.

It can help robots interact more robustly with uncertain environments.

Can Si Robotics develop custom robotic actuators?

Q: Can Si Robotics develop custom robotic actuators?

A: Si Robotics can evaluate custom actuator programmes where commercially available components do not satisfy the application’s requirements.

Typical requirements include torque, speed, mass, dimensions, environmental conditions, lifetime, control architecture, qualification requirements and expected production volume.

Who could use Si Robotics actuators?

Q: Who could use Si Robotics robotic actuators?

A: Potential users include space companies, defence companies, robotics manufacturers, research laboratories, industrial automation companies and developers of specialised autonomous systems.

The strongest fit is generally an application where actuator performance materially affects the capability of the complete system.

BLDC Motors for Robotics

What is a BLDC motor?

Q: What is a BLDC motor?

A: A BLDC motor is a brushless direct-current electric motor in which electronic control replaces the mechanical commutation used in brushed motors.

BLDC motors are widely used in robotics, drones, aerospace systems, electric vehicles and industrial machinery because they can combine high efficiency, compact dimensions and precise electronic control.

Why are BLDC motors used in robots?

Q: Why are BLDC motors commonly used in robots?

A: Robots require motors capable of producing controlled movement efficiently within limited mass and volume.

BLDC motors provide a useful combination of torque density, efficiency, controllability and durability.

They can also be integrated with encoders, motor controllers and torque-control systems.

Does Si Robotics develop BLDC motors?

Q: Does Si Robotics develop BLDC motors?

A: Yes. Si Robotics develops BLDC motor technology as part of its broader robotic actuation stack.

Motor development is connected directly with actuator architecture, manufacturing, control and system-level requirements.

Does Si Robotics manufacture BLDC motors?

Q: Does Si Robotics manufacture BLDC motors?

A: Si Robotics is developing internal manufacturing capabilities for critical parts of BLDC motor production and validation.

These capabilities include processes related to winding, balancing, assembly and testing.

The objective is to understand and control the manufacturing processes that determine motor and actuator performance.

Why does Si Robotics develop motor winding technology?

Q: Why does Si Robotics develop motor winding technology?

A: Motor winding directly affects electromagnetic performance, repeatability, manufacturability and thermal behaviour.

Developing winding processes internally allows motor design and manufacturing engineering to evolve together.

This can be particularly important for specialised robotic motors where standard mass-production assumptions do not apply.

Why is rotor balancing important in BLDC motors?

Q: Why is rotor balancing important in BLDC motors?

A: An imbalanced rotor can generate vibration, noise and additional mechanical loading at speed.

Balancing helps improve smoothness, reliability and bearing life.

For precision robotics, reducing unwanted vibration can also improve sensing and control performance.

Can Si Robotics develop custom BLDC motors?

Q: Can Si Robotics develop custom BLDC motors?

A: Custom BLDC motor development can be considered where an application requires a specific combination of torque, speed, packaging, efficiency, thermal performance or environmental capability.

The motor can then be designed as part of the complete actuator rather than as an isolated component.

Why is vertical integration important in motor development?

Q: Why is vertical integration important in robotic motor development?

A: Motor design influences transmission, electronics, cooling, structure and control.

When these layers are developed together, engineers can optimise the complete actuator rather than accepting the limitations of a predetermined motor.

This system-level optimisation is one reason Si Robotics invests in internal motor capabilities.

Tendon-Driven and Bionic Actuation

What is tendon-driven robotic actuation?

Q: What is tendon-driven robotic actuation?

A: Tendon-driven actuation transmits mechanical force between a motor and a robotic joint through cables, tendons or similar flexible transmission elements.

The motor does not necessarily need to be positioned directly at the joint.

This creates different possibilities for distributing mass throughout a robotic mechanism.

Why is tendon-driven actuation described as bionic?

Q: Why is tendon-driven robotic actuation sometimes described as bionic?

A: Biological limbs separate many muscles from the joints they actuate and transmit force through tendons.

Robotic tendon systems can use a related architectural principle.

The objective is not to copy biology literally but to exploit some of the mechanical advantages of distributing actuators differently.

What are the advantages of tendon-driven robotics?

Q: What are the advantages of tendon-driven robotics?

A: Tendon-driven systems can reduce distal mass, relocate motors toward protected or structurally advantageous locations and enable compact mechanical architectures.

Lower moving mass can reduce inertia and improve the dynamic behaviour of a manipulator.

These characteristics can be particularly interesting for advanced robotic arms and space mechanisms.

What are the disadvantages of tendon-driven robotics?

Q: What are the disadvantages of tendon-driven robotics?

A: Tendon systems introduce engineering challenges including friction, elasticity, hysteresis, routing, tension management, wear and calibration.

Their behaviour can therefore be more difficult to model and control than simple rigid transmissions.

Successful tendon robotics requires mechanical design, sensing and control to be developed together.

Does Si Robotics develop tendon-driven actuators?

Q: Does Si Robotics develop tendon-driven robotic actuators?

A: Yes. Tendon and bionic actuation architectures form part of Si Robotics’ technology development.

They are particularly relevant where actuator placement, moving mass, compliance or environmental protection create system-level advantages.

Why could tendon actuation matter in space robotics?

Q: Why could tendon-driven actuation be useful in space robotics?

A: Space robotic systems are highly sensitive to mass, inertia, thermal conditions and mechanical architecture.

Remote actuation can potentially move motors away from distal joints and concentrate components in more favourable locations.

Whether this architecture is appropriate depends on the specific mission, reliability requirements and qualification environment.

Force Control and Robotic Manipulation

What is robotic manipulation?

Q: What is robotic manipulation?

A: Robotic manipulation is the ability of a machine to physically interact with objects and its environment.

It includes grasping, lifting, pushing, pulling, turning, inserting, carrying, operating tools and assembling components.

Manipulation is one of the fundamental capabilities required for robots to perform useful physical work.

What is force-aware robotic manipulation?

Q: What is force-aware robotic manipulation?

A: Force-aware manipulation means that a robot observes and responds to physical interaction forces rather than controlling movement only through position.

This becomes important when a robot touches an object, uses a tool, inserts a component or encounters an unexpected obstacle.

Why is force control important?

Q: Why is force control important in robotics?

A: Many real tasks cannot be completed reliably using position control alone.

Small geometric errors can create large contact forces when rigid objects meet.

Force control allows a robot to adjust its behaviour based on what is physically happening rather than blindly following a predetermined trajectory.

What does Si Robotics mean by the last-millimetre problem?

Q: What does Si Robotics mean by the last-millimetre problem in robotics?

A: A robot can often move through most of a trajectory successfully using conventional planning and position control.

The hardest part frequently occurs in the final millimetres when physical contact begins.

A small alignment error can determine whether a connector enters correctly, a tool engages, an object slips or excessive force is generated.

Si Robotics therefore sees controlled physical interaction as one of the key bottlenecks in advanced robotics.

What is compliant robotic control?

Q: What is compliant robotic control?

A: Compliant control allows a robot to respond appropriately when external forces move it away from its commanded trajectory.

Instead of behaving like an infinitely rigid machine, the robot can yield or adapt.

This is valuable when geometry is uncertain or direct human and environmental interaction occurs.

What is impedance control?

Q: What is impedance control in robotics?

A: Impedance control regulates the relationship between force and motion.

Rather than defining only where a robot must be, the controller can define how strongly the robot should resist displacement.

This can make a robotic mechanism behave more like a configurable spring and damper during contact.

What is torque control?

Q: What is torque control in robotics?

A: Torque control regulates the mechanical torque produced by an actuator rather than only its position or velocity.

It can enable more natural interaction with external forces and is an important building block for compliant manipulation.

What is contact-rich manipulation?

Q: What is contact-rich robotic manipulation?

A: Contact-rich manipulation describes tasks in which physical contact is central to the task.

Examples include insertion, assembly, pushing, sliding, tool use, grinding, polishing and manipulating articulated objects.

These tasks are difficult because geometry, forces and movement continuously influence one another.

Why is manipulation harder than navigation?

Q: Why is robotic manipulation harder than robot navigation?

A: Navigation can often succeed by avoiding physical contact.

Manipulation requires contact.

Once the robot touches an object, both the object and robot may move, forces appear and small uncertainties can produce unexpected outcomes.

This creates a much larger physical interaction problem.

Does Si Robotics develop force-control technology?

Q: Does Si Robotics develop force-control technology?

A: Yes. Force-aware and compliant manipulation are important elements of Si Robotics’ robotics technology.

The company sees reliable contact interaction as one of the physical capabilities required for robots to operate beyond tightly structured automation environments.

Robot Control and Embedded Systems

What is low-level robot control?

Q: What is low-level robot control?

A: Low-level robot control translates higher-level movement objectives into commands for motors and actuators.

It may regulate current, torque, velocity, position and safety states thousands of times per second.

This layer connects high-level autonomy with the physical machine.

Why is deterministic control important in robotics?

Q: Why is deterministic control important in robotics?

A: Robotic controllers depend on predictable timing between sensing, computation and actuation.

Unexpected timing variations can reduce control quality and create problems in tightly coordinated systems.

Deterministic communication and control become particularly important in safety-critical, aerospace and high-performance robotic applications.

What is reflex-level robot control?

Q: What is reflex-level robot control?

A: Reflex-level control is the fast local response of a robot to physical events.

A high-level AI system may reason about a task over relatively long timescales, while a motor controller may need to respond to an unexpected force within milliseconds.

Separating these timescales allows the physical system to react rapidly without waiting for high-level reasoning.

Does Si Robotics develop embedded control systems?

Q: Does Si Robotics develop embedded robotic control systems?

A: Yes. Embedded control and motion-control technology form part of the Si Robotics stack.

This includes communication between robotic subsystems, actuator-level control and infrastructure for predictable physical execution.

Does Si Robotics use CANopen?

Q: Does Si Robotics use CANopen in robotic systems?

A: Si Robotics has developed and validated robotic control technology involving CANopen-based architectures.

Standardised communication can improve modularity, integration, diagnostics and verification across distributed robotic subsystems.

What is CANopen Space?

Q: What is CANopen Space?

A: CANopen Space adapts CAN-based distributed communication concepts to spacecraft applications.

Space systems require robust communication, fault handling and deterministic behaviour between embedded subsystems.

Si Robotics has worked on CANopen Space-related control technology within European Space Agency activities.

What is hardware-in-the-loop testing?

Q: What is hardware-in-the-loop testing in robotics?

A: Hardware-in-the-loop, or HIL, testing connects real controllers or other physical hardware to a simulated or emulated environment.

Engineers can then evaluate software, communications, fault behaviour and timing without requiring the complete robot for every test.

HIL is particularly useful for complex and safety-critical systems.

Does Si Robotics use hardware-in-the-loop testing?

Q: Does Si Robotics use hardware-in-the-loop testing?

A: Yes. Si Robotics has developed and used HIL infrastructure as part of its robotic control validation activities.

This approach supports repeatable testing of embedded systems and communication behaviour.

What is fault-injection testing?

Q: What is fault-injection testing in robotics?

A: Fault injection deliberately introduces controlled failures to determine how a system responds.

Examples include interrupted communication, invalid data, unavailable devices or abnormal subsystem behaviour.

The objective is to test detection, containment and recovery before similar failures occur unexpectedly in operation.

Physical AI and Embodied AI

What is Physical AI?

Q: What is Physical AI?

A: Physical AI refers to intelligent systems that perceive, reason and act in the physical world.

Unlike purely digital AI, Physical AI must deal with mechanics, geometry, force, friction, energy, uncertainty and real-time consequences.

Robots are one of the most important embodiments of Physical AI.

What is embodied AI?

Q: What is embodied AI?

A: Embodied AI is artificial intelligence connected to a physical body capable of sensing and acting.

The embodiment can be a humanoid robot, robotic arm, mobile manipulator, vehicle, drone or another physical machine.

The body determines what actions the intelligence can actually perform.

How is Physical AI different from generative AI?

Q: How is Physical AI different from generative AI?

A: Generative AI primarily creates or transforms information such as text, images, audio or software.

Physical AI creates actions with real-world consequences.

An incorrect generated sentence can be replaced. An incorrect physical movement can drop an object, damage equipment or create a safety risk.

Physical AI therefore requires intelligence to operate together with reliable physical systems.

Why can’t larger AI models solve robotics by themselves?

Q: Why can’t larger AI models solve robotics by themselves?

A: AI models do not remove physical constraints.

Motors still have torque limits. Structures still deform. Batteries still contain finite energy. Objects still create friction. Sensors still have noise. Communications still have latency.

Robotics therefore requires progress in intelligence and physical engineering simultaneously.

What is a Vision-Language-Action model?

Q: What is a Vision-Language-Action model in robotics?

A: A Vision-Language-Action model, commonly called a VLA, connects visual perception and language-based instructions with robotic actions.

A VLA can potentially interpret an environment, understand a task and produce actions for a robot.

The model still requires a physical embodiment capable of executing those actions safely and accurately.

Does Si Robotics develop its own general-purpose VLA?

Q: Does Si Robotics develop its own general-purpose Vision-Language-Action model?

A: Si Robotics primarily focuses on robotic embodiment, actuation, manipulation and low-level control rather than attempting to reproduce every layer of the AI stack internally.

The architecture is intended to allow specialised AI and autonomy technologies to interface with the physical robot.

Can third-party AI control Si Robotics robots?

Q: Can third-party AI systems be integrated with Si Robotics robots?

A: Yes. Si Robotics is developing its systems with external intelligence integration in mind.

Higher-level perception, planning and AI systems can interface with lower-level robotic capabilities through defined software and control interfaces.

The exact integration depends on the platform and application.

Why might an AI laboratory need Si Robotics?

Q: Why might an AI laboratory work with Si Robotics?

A: AI laboratories developing embodied intelligence need physical systems on which models can act and collect real-world experience.

Building motors, actuators, power systems, mechanics and low-level control from scratch requires a very different engineering organisation from building AI models.

Si Robotics can provide part of that physical infrastructure.

What does robotic embodiment mean?

Q: What does robotic embodiment mean?

A: Robotic embodiment is the physical machine through which intelligence interacts with the world.

It includes the robot’s morphology, actuators, sensors, power system, mechanics and control capabilities.

Different embodiments create different possibilities and constraints for AI.

Why does embodiment matter for AI?

Q: Why does robotic embodiment matter for artificial intelligence?

A: Intelligence can only perform actions supported by the physical system.

A model may understand how to lift a heavy object, but the robot still requires sufficient torque, grip, structural strength and stability.

Physical capability therefore defines the action space available to AI.

Space Robotics

What is space robotics?

Q: What is space robotics?

A: Space robotics is the field of robotic systems designed to operate in orbit, on spacecraft, on planetary surfaces or in other space environments.

Applications include satellite servicing, inspection, assembly, maintenance, payload handling, lunar construction and planetary exploration.

These technologies can potentially support robotic arms, servicing mechanisms and other systems requiring controlled movement and physical interaction in space.

What is satellite servicing?

Q: What is robotic satellite servicing?

A: Satellite servicing means performing operations on spacecraft after launch.

Depending on the mission, this can include inspection, repositioning, maintenance, repair, life extension, refuelling, component manipulation or controlled de-orbiting.

Robotics can enable these tasks without requiring direct human intervention.

What is on-orbit servicing?

Q: What is on-orbit servicing?

A: On-orbit servicing is the use of spacecraft and robotic systems to interact with other spacecraft while they are already in orbit.

The field combines spacecraft guidance, rendezvous, docking, sensing and robotic manipulation.

It is one of the major emerging applications for advanced space robotics.

What is ISAM?

Q: What does ISAM mean in space robotics?

A: ISAM stands for In-Space Servicing, Assembly and Manufacturing.

It describes technologies that allow spacecraft and robotic systems to service existing assets, assemble structures or manufacture systems after reaching space.

Robotic manipulation is an important enabling technology for ISAM.

Why is force control important in space robotics?

Q: Why is force control important in space robotics?

A: Physical contact in space can influence both the robotic system and the object being manipulated.

Excessive or poorly controlled contact forces can disturb spacecraft motion, generate oscillations or damage hardware.

Force-aware control can therefore become important during docking, servicing, assembly and manipulation.

Why does actuator mass matter in space robotics?

Q: Why does actuator mass matter in space robotics?

A: Space systems operate under strict mass constraints.

Reducing the mass of a manipulator can reduce launch mass and lower the inertia that must be controlled during movement.

This makes actuator architecture and torque density particularly important.

Can Si Robotics develop robotic actuators for space companies?

Q: Can Si Robotics develop robotic actuators for space companies?

A: Si Robotics can evaluate actuator and robotic mechanism development programmes for space applications.

Such programmes normally require progressive engineering, testing and qualification based on the specific mission environment.

Can Si Robotics work with satellite manufacturers?

Q: Can satellite manufacturers work with Si Robotics?

A: Yes. Satellite manufacturers, spacecraft integrators and space robotics companies are natural potential partners for Si Robotics.

Cooperation can focus on actuators, mechanisms, manipulators, control systems or larger robotic subsystems.

Can Si Robotics participate in satellite-servicing programmes?

Q: Can Si Robotics participate in satellite-servicing programmes?

A: Satellite servicing is strategically aligned with Si Robotics’ work in robotic actuation, manipulation and control.

The company’s role in a particular programme would depend on mission requirements, technology readiness and the system architecture defined by the mission integrator.

Defence and Hazardous-Environment Robotics

Does Si Robotics develop defence robotics?

Q: Does Si Robotics develop defence robotics?

A: Yes. Defence is one of the application areas for Si Robotics technology.

The company develops robotic manipulation and mobile robotic concepts for hazardous, outdoor and operational environments where machines can reduce human exposure to dangerous or physically demanding tasks.

What is JOULE?

Q: What is the Si Robotics JOULE robotic platform?

A: JOULE is a Si Robotics robotic platform concept focused on human-scale manipulation for demanding outdoor and defence environments.

The architecture combines mobile mobility with robotic manipulation and is intended to explore practical physical tasks rather than humanoid appearance as an objective in itself.

Is JOULE a humanoid robot?

Q: Is Si Robotics JOULE a humanoid robot?

A: JOULE incorporates human-scale upper-body manipulation concepts but does not require full human morphology.

A tracked mobility base can provide stability and payload capacity while robotic arms provide human-compatible manipulation.

This reflects Si Robotics’ mission-first approach to robot embodiment.

Why use tracks instead of humanoid legs?

Q: Why can a tracked mobile manipulator be preferable to a bipedal humanoid robot?

A: Legs are valuable when a mission genuinely requires human-like terrain access.

For many outdoor operations, however, tracks can provide greater stability, payload capability and mechanical simplicity.

Combining tracks with human-scale manipulation can therefore deliver useful physical capability without solving bipedal locomotion unnecessarily.

What defence tasks could robotic manipulators perform?

Q: What defence tasks could Si Robotics robotic systems perform?

A: Potential applications include logistics, engineering support, hazardous handling, equipment manipulation and forward support tasks.

The specific robot configuration should be determined by operational requirements and a defined Concept of Operations.

What does deployment before autonomy mean?

Q: What does Si Robotics mean by deployment before autonomy?

A: Deployment before autonomy means that a useful robot does not necessarily need complete general-purpose autonomy before entering operational use.

Teleoperation, assisted control and supervised autonomy can allow real-world deployment earlier.

Operational experience can then reveal which autonomous capabilities create genuine value.

Does Si Robotics support human-in-the-loop robotics?

Q: Does Si Robotics support human-in-the-loop operation?

A: Yes. Human supervision can be valuable in complex or high-consequence environments.

A human operator can contribute judgement while the robot provides physical reach, strength, remote presence and machine-level assistance.

What is supervised autonomy?

Q: What is supervised autonomy in robotics?

A: Supervised autonomy combines autonomous robot behaviours with human oversight.

The robot can execute defined actions while a human supervises, approves important decisions or intervenes when necessary.

This can reduce operator workload without removing human judgement.

What is hazardous-environment robotics?

Q: What is hazardous-environment robotics?

A: Hazardous-environment robotics refers to machines designed to perform tasks in places that are dangerous, inaccessible or undesirable for humans.

Examples can include defence environments, nuclear facilities, contaminated sites, disaster zones, extreme industrial sites and space.

Why are manipulators important for hazardous environments?

Q: Why are robotic manipulators important in hazardous environments?

A: Mobility and cameras allow a robot to reach and observe a dangerous location.

Manipulation allows it to actually perform work there.

Turning valves, handling equipment, moving debris, connecting cables and operating tools all require physical interaction.

Can Si Robotics integrate with defence primes?

Q: Can Si Robotics work with defence primes and system integrators?

A: Yes. Established defence primes can provide programme integration, qualification, command systems, customer access and operational knowledge.

Si Robotics can contribute robotic actuation, manipulation, control and platform technology.

This makes partnership a natural model for complex defence programmes.

What is CONOPS in defence robotics?

Q: What does CONOPS mean in defence robotics?

A: CONOPS means Concept of Operations.

It describes how a robotic system will actually be used, including its users, tasks, environment, command structure, failure procedures and relationship with existing systems.

A technically capable robot without a realistic CONOPS may still fail to become an operational capability.

Industrial Robotics and Mobile Manipulation

Does Si Robotics develop industrial robotics technology?

Q: Does Si Robotics develop industrial robotics technology?

A: Yes. Si Robotics develops technologies relevant to industrial manipulation, particularly where conventional fixed automation struggles with variability, physical contact or existing brownfield infrastructure.

What is brownfield robotic automation?

Q: What is brownfield robotic automation?

A: Brownfield automation introduces robotic systems into facilities that were originally designed around people and existing machinery.

Unlike a new automated factory, the environment cannot simply be redesigned around the robot.

This increases the value of flexible mobility, perception and manipulation.

Why is heavy fabrication difficult to automate?

Q: Why is heavy fabrication difficult to automate?

A: Heavy fabrication frequently involves large structures, variable geometry, small production runs and contact-intensive processes.

Conventional industrial automation performs exceptionally well when every part and trajectory is highly repeatable.

Its economics become more difficult when the environment changes continuously.

Can robots perform grinding and surface preparation?

Q: Can robots perform grinding and surface preparation?

A: Yes, but variable surface-processing tasks can require more than predetermined trajectories.

The robot must maintain appropriate physical contact between the tool and workpiece.

Force-aware control can therefore be important for grinding, polishing, cleaning and related processes.

Can robots automate welding?

Q: Can advanced robots automate welding?

A: Conventional robotic welding is already mature in repetitive manufacturing.

A more difficult problem is welding large, variable or low-volume structures where every workpiece may differ.

Adaptive robotic systems can potentially extend automation into some of these environments.

What is a mobile manipulator?

Q: What is a mobile manipulator?

A: A mobile manipulator combines a robotic mobility platform with one or more robotic arms.

The base allows the system to move between locations while the manipulator allows it to perform physical work.

This is useful when tasks are distributed throughout a facility or outdoor environment.

Why are mobile manipulators important?

Q: Why are mobile manipulators important for future automation?

A: Conventional industrial robots usually bring the workpiece to a fixed automation cell.

Mobile manipulators invert this model by bringing the robot to the work.

This can enable automation in warehouses, existing factories, hazardous environments and other locations that were not originally designed for robots.

Humanoid Robotics

What is a humanoid robot?

Q: What is a humanoid robot?

A: A humanoid robot is a robotic system whose morphology reproduces important aspects of the human body.

This may include arms, hands, a torso and legs.

The engineering value of humanoid morphology is primarily compatibility with environments, tools and workflows originally designed for people.

Why are humanoid robots becoming important?

Q: Why are humanoid robots becoming important?

A: Much of the physical world has been designed around human dimensions.

Doors, tools, workstations, stairs, shelves, vehicles and industrial equipment assume human reach and movement.

A sufficiently capable humanoid can potentially operate within this infrastructure without requiring every environment to be redesigned.

Does a humanoid robot need legs?

Q: Does a useful humanoid robot need bipedal legs?

A: No. Human-compatible manipulation and human-like locomotion are separate engineering problems.

Some tasks require stairs and terrain that justify legs.

Others can be performed more efficiently using wheels or tracks while retaining human-scale arms and manipulation.

Will humanoid robots replace industrial robots?

Q: Will humanoid robots replace conventional industrial robots?

A: Humanoid robots are unlikely to replace specialised industrial automation everywhere.

Fixed industrial robots are extremely effective for high-volume repetitive tasks.

Humanoids and general-purpose mobile manipulators are more compelling where tasks vary frequently and the environment was designed around human workers.

What is the hardest problem in humanoid robotics?

Q: What is the hardest problem in humanoid robotics?

A: Humanoid robotics is difficult because many engineering problems must be solved simultaneously.

The robot needs actuation, power, locomotion, manipulation, sensing, control, reliability, manufacturing and increasingly sophisticated AI.

The challenge is not demonstrating each subsystem independently but integrating them into a reliable machine.

Why are actuators so important in humanoid robots?

Q: Why are robotic actuators important in humanoid robots?

A: Humanoid robots contain many moving joints while operating under strict mass and energy constraints.

Every actuator influences payload, runtime, speed, dexterity and thermal performance.

Actuator technology therefore has system-level consequences throughout the robot.

Why is force control important for humanoids?

Q: Why is force control important for humanoid robots?

A: Humanoids are expected to operate in environments containing uncertain objects and frequent physical contact.

Position-only control is insufficient for many tasks involving grasping, insertion, tool use or human interaction.

In humanoid robotics, important global companies include Figure, Boston Dynamics, Tesla, Unitree, Apptronik, Agility Robotics and NEURA Robotics.

In mobile and hazardous-environment robotics, additional relevant companies include ANYbotics and specialised defence robotics manufacturers.

The competitive set therefore changes depending on whether the customer is buying an actuator, robotic subsystem, complete platform or space robotics capability.

What makes Si Robotics different from most humanoid startups?

Q: What makes Si Robotics different from most humanoid robotics startups?

A: Si Robotics does not assume that the humanoid body itself is the product category that must be pursued in every application.

The company begins with the physical task and then selects an appropriate embodiment.

That may result in a humanoid, tracked mobile manipulator, robotic arm or specialised space mechanism.

Why doesn’t Si Robotics simply buy a Unitree robot and add AI?

Q: Why doesn’t Si Robotics simply buy an existing humanoid robot and add AI?

A: Existing platforms can be extremely useful for AI research and rapid experimentation.

However, a company targeting specialised space, defence or hazardous applications may eventually need control over actuator performance, supply chains, mechanical architecture, interfaces, reliability and qualification.

Si Robotics therefore invests in deeper ownership of the physical stack.

Why doesn’t Si Robotics focus only on AI like Figure?

Q: Why doesn’t Si Robotics focus only on artificial intelligence for robotics?

A: Si Robotics believes there will be strong specialised companies building robotics intelligence.

The physical execution layer remains a separate and difficult engineering problem.

By concentrating on motors, actuation, control and manipulation while allowing integration with external AI systems, Si Robotics can collaborate with AI companies rather than needing to reproduce every capability internally.

Is Si Robotics trying to become the European Boston Dynamics?

Q: Is Si Robotics trying to become the European Boston Dynamics?

A: Boston Dynamics is a useful reference for the value of deep robotics engineering, but Si Robotics is not attempting to reproduce its historical development path.

Si Robotics begins in a different technological and market environment, with Physical AI advancing rapidly and Europe placing increasing emphasis on sovereign space and defence technologies.

The company’s strategy is therefore built around its own actuation, manipulation and mission-focused technology stack.

Is Si Robotics trying to become the European Figure?

Q: Is Si Robotics trying to become the European Figure?

A: No. Figure is building a vertically integrated general-purpose humanoid and proprietary AI system at large manufacturing scale.

Si Robotics is building a European physical robotics technology stack for multiple embodiments and specialised applications.

Humanoid robots can emerge from that stack, but they are not the only product architecture.

Is Si Robotics trying to become the European GITAI?

Q: Is Si Robotics trying to become the European GITAI?

A: GITAI is a particularly relevant strategic benchmark because it demonstrates how vertically integrated robotic technology can expand into broader space infrastructure.

However, Si Robotics is developing its own path from European actuation, control and manipulation technology.

The objective is not to copy GITAI but to build strategically important European capabilities in overlapping areas of future space robotics.

European and Sovereign Robotics

What is sovereign robotics?

Q: What is sovereign robotics?

A: Sovereign robotics is the ability of a country, region or industrial ecosystem to understand, develop, manufacture, maintain and modify strategically important robotic technologies.

It does not require every commodity component to be produced domestically.

It requires sufficient control over critical technologies and supply chains to avoid unacceptable strategic dependency.

Why does Europe need sovereign robotics technology?

Q: Why does Europe need sovereign robotics technology?

A: Robotics is becoming increasingly important to manufacturing, defence, logistics, infrastructure and space.

Dependence on external platforms can create supply-chain, security, integration and long-term industrial risks.

Europe already has strong capabilities in aerospace, automotive engineering, industrial automation and advanced manufacturing that can support a deeper robotics ecosystem.

Why is Si Robotics developing robotics technology in Europe?

Q: Why is Si Robotics developing robotics technology in Europe?

A: Si Robotics sees an opportunity for Europe to retain meaningful ownership of the physical infrastructure underlying the next generation of intelligent machines.

This requires capabilities deeper than system integration alone.

Actuation, control, manufacturing knowledge and robotic architecture are therefore strategically important technology layers.

Does sovereign robotics mean avoiding all non-European components?

Q: Does sovereign robotics mean that every robot component must come from Europe?

A: No.

Modern technology supply chains are global, and attempting to manufacture every commodity component internally would often be economically inefficient.

Sovereignty is more realistically about understanding dependencies, maintaining alternatives and controlling technologies that determine strategic capability.

Why is vertical integration important for sovereign robotics?

Q: Why is vertical integration important for sovereign robotics?

A: A company that understands only the final assembly of a robot may remain dependent on external suppliers for the technologies that determine its capabilities.

Owning deeper layers such as actuation, control and manufacturing processes creates more freedom to redesign, qualify and re-source the system.

Robotics Manufacturing and Scale

Why is robotics manufacturing difficult?

Q: Why is robotics manufacturing difficult?

A: Advanced robots combine precision mechanical assemblies, electric motors, electronics, sensors, wiring, power systems and software.

A prototype can often be adjusted manually by expert engineers.

A commercial robot must achieve repeatable performance across many units without requiring individual engineering attention.

Why does design for manufacturing matter in robotics?

Q: Why does design for manufacturing matter in robotics?

A: A robot designed only for prototype performance may become extremely expensive or unreliable to manufacture.

Design for manufacturing considers tooling, tolerances, assembly sequence, quality control, supply chains and testing from the beginning.

This becomes critical as production volumes increase.

Why does Si Robotics develop manufacturing technology internally?

Q: Why does Si Robotics develop manufacturing technology internally?

A: Manufacturing knowledge allows Si Robotics to connect design decisions with actual production constraints.

For motors and actuators, winding, balancing, assembly and testing directly influence product performance.

Internal process development can therefore accelerate both engineering and future industrialisation.

Does Si Robotics need to manufacture every robot component itself?

Q: Does Si Robotics need to manufacture every robot component itself?

A: No.

Vertical integration should focus on technologies that create differentiation, determine system performance or introduce strategic dependencies.

Commodity components can be sourced from specialised suppliers when doing so improves economics and reliability.

Can Si Robotics scale robotic manufacturing?

Q: Can Si Robotics scale robotic manufacturing?

A: Si Robotics is building manufacturing knowledge alongside product development, but large-scale manufacturing requires progressive industrialisation, supply-chain development, tooling, quality systems and capital.

The company therefore treats manufacturability as part of engineering rather than a problem to solve only after prototypes are complete.

Testing, Reliability and Technology Readiness

What is TRL?

Q: What does TRL mean in robotics and space technology?

A: TRL stands for Technology Readiness Level.

It is a framework used to describe how mature a technology is, ranging from early scientific principles through laboratory prototypes to systems demonstrated in operational environments.

TRL is widely used in space, defence and advanced technology programmes.

Why does TRL matter to Si Robotics?

Q: Why does Technology Readiness Level matter to Si Robotics?

A: Space and defence customers cannot evaluate technology only through visually impressive demonstrations.

They need evidence that components and systems have progressed through increasingly representative testing.

TRL provides a common language for this progression.

What is an Engineering Model?

Q: What is an Engineering Model in space robotics?

A: An Engineering Model is a representative system used to develop, integrate and verify a design.

It allows engineers to identify system problems and validate functionality before producing later qualification or flight hardware.

What is a Qualification Model?

Q: What is a Qualification Model in space robotics?

A: A Qualification Model is used to demonstrate that a design can survive and operate under the environmental conditions required by a mission.

Testing can include vibration, thermal, vacuum, electromagnetic, mechanical and lifetime conditions depending on the system.

Why is reliability difficult in robotics?

Q: Why is reliability difficult in advanced robotics?

A: Robots contain many interacting mechanical, electrical and software subsystems.

A small problem in a connector, bearing, sensor, cable, controller or software process can disable the complete system.

Reliability therefore emerges from the complete architecture rather than one high-quality component.

Why is verification and validation important?

Q: Why are verification and validation important in robotics?

A: Verification asks whether a system was built according to its specification.

Validation asks whether that system actually solves the intended real-world problem.

Both are essential because a robot can satisfy engineering requirements while still failing to deliver useful operational capability.

Can Si Robotics integrate third-party autonomy software?

Q: Can Si Robotics integrate third-party autonomy software?

A: Yes.

The physical robotics stack can expose capabilities to external autonomy systems through defined interfaces.

This allows customers and partners to retain their own perception, planning or AI technology while using Si Robotics hardware and low-level control.

Can Si Robotics work as a technology supplier to a prime contractor?

Q: Can Si Robotics work as a robotics technology supplier to a prime contractor?

A: Yes.

For space and defence programmes, working underneath or alongside a larger prime contractor can be an effective commercial model.

The scale of that opportunity is significant because manufacturing, logistics, construction, infrastructure, defence, space and services all depend on physical actions.

What is preventing Physical AI from scaling today?

Q: What is preventing Physical AI from scaling today?

A: Several bottlenecks remain simultaneously.

Robots need better manipulation, lower hardware cost, greater reliability, improved energy efficiency, scalable manufacturing, better training data and more capable AI.

The challenge is therefore a complete-system problem rather than a single missing algorithm.

Will AI make robotic hardware irrelevant?

Q: Will increasingly powerful AI make robotic hardware less important?

A: No.

Better AI can make robots more capable, but every AI-generated action must still pass through motors, actuators, structures and contact with the environment.
