Robotic manipulation for environments
where humans should not operate
Si Robotics develops remotely operated manipulation systems and proprietary actuation technology for space, defence and hazardous environments.
2x ESA contacts · Space robotics · Defence prime programmes · Full-stack hardware built in-house
A human-scale manipulation platform built to replace people in hazardous physical operations.
Tracked mobility
Dual-arm manipulation
Force-aware control
Human-supervised operation
Deployable before general-purpose autonomy exists

& maintenance
In-space servicing, assembly & manufacturing (ISAM)
Operations in contaminated environments
One architecture to be deployed wherever physical work is dangerous, remote or inaccessible to humans.
The physical autonomy inflection point
AI is leaving the screen and entering the physical world.
Need for autonomy ↑
AI capability ↑
Human availability ↓
Proven through space
Our manipulation and actuation technology is being developed through two European Space Agency programmes.
Orbital servicing · Lunar infrastructure · Space manipulation
One stack. Multiple robotic systems
Remote Actuation Modules
Centralised motors, power electronics and embedded control
Tendon-driven Joint Modules
Compact, lightweight mechanical joints designed for robotic manipulation
Motion Controllers
Deterministic control for multi-axis robotic systems
Robotic Systems
Integrated systems built on the same hardware architecture
Manipulators
Integrated robotic
tendon-driven grippers
A common manipulation stack across multiple robotic systems.
Why our robots are different
Joint
Provides motion output to the mechanism
Tendon / Cable
Transmits motion with low friction and high load capacity
Remote Actuator
Converts rational motion into tendon movement
Drive Module
Enclosed unit containing motors, electronics and supporting systems
LOW INERTIA AT THE JOINT
Higher speed and efficiency
EFFICIENT POWER TRANSMISSION
Low friction, high load capacity
HIGH TORQUE DENSITY
Precise and controllable actuation
PROTECTED DRIVE UNIT
Sealed, shielded and thermally managed
Remote Actuation Architecture
We own the critical layers that determine performance, cost and supply-chain sovereignty.
Vertical Integration
Built to integrate,
not replace the defence ecosystem.
We build the machine
From motor winding and actuator assembly to system integration and field testing — the critical hardware behind JOULE is built in-house.
Backed and supported by
Built in Poland. Designed for allied markets.
European engineering and manufacturing for space and defence across Europe, the Middle East, Japan and the United States.
Transparent supply chain.
Designed for allied deployment and localisation.
Sovereign Actuation Business Unit
We own the actuation stack underneath robotics. High-performance BLDC propulsion for defence and space autonomous systems.
Designed and manufactured in Poland.
Build with us
We work with defence primes, armed forces, space companies and technology partners developing robotic capabilities for environments where humans should not operate.
for the next generation of space and defence systems
