Three-legged MARM robot: The future of tending to spacecraft in orbit
Introduction:
Introducing MARM, the multi-arm relocatable manipulator robot designed by the team at the Istituto Italiano di Tecnologia (IIT). Reminiscent of the bipedal robots from the 1972 film “Silent Running,” MARM features three limbs for enhanced dexterity and mobility. Developed as part of the European Space Agency’s MIRROR project, MARM is specifically designed to install and remove orbital replacement units (ORUs) on spacecraft. Its swivel-based pelvis and articulated limbs allow for stability and precise movement. This semi-autonomous robot uses onboard cameras and human guidance to perform tasks with precision.

MARM: The Three-Leg Robot Revolutionizing Spacecraft Maintenance
Science fiction fans may find the MARM robot reminiscent of the bipedal robots from the 1972 film “Silent Running.” However, the new MARM robot, developed by a team at the Istituto Italiano di Tecnologia (IIT), has three limbs for enhanced dexterity and mobility. Led by Nikolaos Tsagarakis, the team behind the WALK-MAN firefighting humanoid robot and the Centauro two-armed/four-legged robot created MARM as part of the European Space Agency’s MIRROR project.
Designed for Spacecraft Maintenance
The MARM robot, short for Multi-Arm Relocatable Manipulator, was primarily designed to navigate the exterior of spacecraft and install or remove orbital replacement units (ORUs). ORUs are modular spacecraft components that can be easily replaced when needed. While the robot has the potential to perform various tasks, its main focus is to ensure the smooth operation of spacecraft by handling the installation and replacement of these components.
Features and Functionality
MARM consists of a swiveling pelvis-like base and three articulated limbs that serve as both arms and legs. Each foot/hand of the robot has a latching mechanism that engages with the hexagonal insulating tiles covering the spacecraft. This mechanism allows the robot to anchor itself securely to the spacecraft and replace tiles if necessary. Additionally, the latching system facilitates charging the robot’s battery and sending/receiving data through docking stations on the spacecraft’s exterior.
Enhanced Stability and Flexibility
One of the advantages of MARM’s design is its ability to maintain at least two points of contact while walking on three legs. This ensures stability and allows the robot to move in any direction effortlessly. When using one limb and the moveable pelvis for a task, the other two limbs act as anchors, providing a stable platform for optimal performance.
Future Plans for MARM
According to Tsagarakis, MARM is expected to become semi-autonomous in the future. While onboard cameras enable precise foot placement, a human operator will likely guide the robot as it handles ORUs. The next steps for MARM involve testing the robot in an Earth-based physical simulator before being deployed in real spacecraft maintenance operations.

Developed by the IIT team, MARM aims to enhance the efficiency and reliability of spacecraft operations while ensuring the safety and ease of maintenance tasks. Stay tuned for further developments in this exciting field of robotics and space exploration.
