SpaceHopper

A hopping robot for asteroid exploration. In the SpaceHopper project, students at ETH Zurich developed a robot capable of moving in low gravity environments through hopping motions. It is intended to be used in future space missions to explore small celestial bodies. The exploration of asteroids and moons could provide insights into the formation of the universe and they may contain valuable minerals that humanity could use in the future. The project began in 2021 as an ETH focusproject for bachelor's students. Now, it is being continued as a regular research project. A particular challenge in developing exploration robots for asteroids is that, unlike larger celestial bodies like Earth, there is low gravity on asteroids and moons. The students have therefore tested their robot's functionality in zero gravity during a parabolic flight. The parabolic flight was conducted in collaboration with the European Space Agency as part of the ESA Academy Experiments Programme.
