Summary
Helios debuted on May 20 as a 160-cm, 32-kg humanoid built specifically for space stations, where it is meant to handle maintenance, inspections and cargo unloading.
Four arms and no legs let the robot move hand over hand in microgravity, bracing with two limbs while using the other two for tools or payloads; it can work autonomously or by remote control.
Orbit Robotics says the design targets repetitive crew tasks that can cost about $140,000 an hour in astronaut time, potentially shifting human crews toward science and mission-critical work.
A 3-hour battery life, 28 degrees of freedom and a 2 km/h top speed position Helios for commercial orbital stations as post-ISS infrastructure plans expand.
After a major ISS robot recently failed, how can Helios guarantee it won’t become another problem for astronauts to fix?
With ISS retirement looming and replacement programs delayed, can new space robots find a home in time?
Is building a humanoid robot for chores the right path, or should we design space stations that don't need them?
Four Arms, No Legs: Helios and the New Standard for Robotic Assistance in Microgravity
Overview
In May 2026, Orbit Robotics unveiled Helios, a groundbreaking humanoid robot designed to operate in the weightless conditions of space. Helios stands out with its unique four-arm, legless design—a practical choice since legs are unnecessary in microgravity. This configuration allows Helios to efficiently assist astronauts, enhancing their capabilities and efficiency during missions. Orbit Robotics emphasizes that Helios is meant to help astronauts, not replace them, by taking on routine and hazardous tasks. This approach supports astronauts in focusing on more critical mission objectives, marking a new era for human-robot collaboration in space.
