Zurich Startup Orbit Robotics Unveils Four-Armed Robot Helios for Space Station Maintenance

Orbit Robotics, a startup based in Zurich, has introduced Helios, a four-armed robot designed to operate within space stations. Targeting the 35% of crew time dedicated to maintenance, Helios aims to reduce costs associated with routine logistics work, estimated at $140,000 per astronaut hour. The robot features two arms that stabilize it while the other two perform tasks like handling cargo and tools. Its tendon-driven design minimizes weight while maintaining necessary mobility, and its rolling-contact elbow joint ensures smooth movement in microgravity. As space exploration expands, the need for effective maintenance solutions like Helios is expected to grow, particularly with increasing cargo and personnel in orbit.
