We've been experimenting with artificial intelligence on the ISS for years, but it’s value in assisting astronauts with simple tasks has only recently been realized. CIMON (Crew Interactive Mobile Companion) is the latest AI tech being used on the ISS. CIMON is a floating robot that keeps track of tasks and stores information for the astronauts. CIMON also collects and processed data that could help us better develop tech here on Earth.
In addition to CIMON, there are also 3 free flying satellites on board the International Space Station called SPHERES (Synchronized Position Hold Engage and Reorient Experimental Satellite). These free floating satellites operate semi-autonomously, and rely on small carbon-dioxide thrusters to get around.
