Orbot Robotics’ space robot has four arms, but its Goro physique has a purpose
Orbit Robotics has introduced Helios, a four-armed robot designed for use in space. Unlike traditional robots, Helios is tailored for the unique challenges of microgravity, focusing on assisting astronauts with various tasks. Its innovative design features tendon-driven arms that enhance mobility and functionality in confined spaces.
- ▪Helios is a four-armed robot created by Zurich-based Orbit Robotics.
- ▪The robot is designed to assist astronauts with repetitive tasks in space stations.
- ▪Its arms are tendon-driven, making them lighter and more efficient for movement in microgravity.

Opening excerpt (first ~120 words) tap to expand
Helios is a new four-armed robot from Zurich-based Orbit Robotics, and at first glance, it reminded me of Goro from Mortal Kombat. But unlike the prince from Outworld, Helios is not built for combat. It is designed to help astronauts on space stations with the repetitive, time-consuming work that keeps life in space running. Orbit Robotics says that in microgravity, legs are not much help. Instead of walking or standing, Helios needs to move through tight station interiors, hold itself steady, and handle cargo, tools, or equipment. Its four-arm design turns extra limbs into both mobility aids and working hands. Why four arms make sense in orbit The design looks strange because most humanoid robots, like the Unitree G1 and Tesla Optimus, are still shaped around Earth-based movement.
