Robots play on board the ISS
What sounds strange at first has an important background. The two robots 'Cimon' from the German Space Agency at the German Aerospace Center (DLR) and 'Int-Ball2' from the Japanese space agency JAXA on board the International Space Station ISS communicated with each other for the first time in the ICHIBAN experiment. ICHIBAN is Japanese and stands for the first, i.e. the first experiment of its kind in space.
