Robot-astronaut Interaction in space turned to be a bizarre humour.

“Be nice, please,” and “don’t be so mean,” Robot named SIMON says to ESA astronaut Alexander Gerst after being a bit irritated in the first man-machine interaction of CIMON (Crew Interactive Mobile Companion) with IBM Watson artificial intelligence.

The robot CIMON is meant to assist the crew members on International Space Station with tasks to provide some entertainment and fun-filled activities to help improve mood.
