This robot would get on fine on Mars. Students from the University of Bialystok proved this during the international robot competition „University Rover Challenge“ in Utah desert in 2011. Even when fully equipped, the exploration device weighs just 38 kg and is made almost completely of plastic. It goes without saying that the bearings are not made of metal either. After all, the plastic plain bearings used have the enormous advantage of not being affected in any way by dust, humidity and large fluctuations in temperature.
