Alexander Gerst, has his first day with co-worker CIMON the AV robot. CIMON stands for Crew Interactive Mobile CompanioN. It's a medicine-ball-sized plastic sphere that was 3D printed and equipped with AI software by IBM Watson. Airbus for the German Aerospace Center (DLR) built the robotic companion which free-flies around the ISS helping out with routine tasks, and providing the kind of companionship that Tom Hanks and Wilson the volleyball pioneered 18 years ago in the movie Castaway.
Except for the bickering.
