Space is an inhospitable environment for human presence, thus making a particularly interesting domain for robotic presence. Space Robotics encompasses two tracks: the orbital track, targeting robot vehicles in microgravity environments, such as orbital or deep space voyages; and the planetary track, encompassing robots that either operate on the surface of planets or small bodies, as asteroids, or near then, e.g., landers.
At IRSg we have been interested in several problems in the domain of Space Robotics. These include:
- collaborative free-flyer robots for intra-vehicular microgravity environments, namely inside a space stations, such as the ISS, in interaction with astronauts
- mobile robots for planetary exploration, such as on the surface of Mars or the Moon
- innovative attitude control mechanisms, such as reaction sphere actuators, holding several advantages over conventional reacton wheels
- formation state estimation and control for multiple spacecraft formation, including a complete Guidance, Navigation, and Control (GN&C) system
