This article focuses on the rolling robot developed by engineers at Swedish company Rotundus. The rolling robot is based on designs originally intended for planetary exploration. But last year Rotundus was spun out from the Angstrom Space Technology Centre at the University of Uppsala with the intention of developing terrestrial markets for the technology. To get the robot to move, a pendulum mounted within the sphere is lifted in the direction of travel. This moves the centre of mass to a position in front of the contact point between the ball and the ground and the ball starts rolling.
