Models of the SPHERES robots sent to the International Space Station. The robots are programmed by students on Earth to perform operations based on real-life situations. Compressed air is used to move the spheres in all directions.
ESA participation in the pilot programme of ZeroRobotics involved collaborating with various universities and academic institutes. ESA provided the opportunity to send teachers from universities to the Massachusetts Institute of Technology to receive training in Spheres operation and coding. The skills learnt were then passed on to the local high school teachers whose teams participated in the event.
