SpaceMouse (1981–1993)
At the end of the seventies, the DLR institute for robotics and mechatronics started research on devices for the 6 DoF control of robot grippers in Cartesian space. In 1982-1985, the first prototype applications showed that DLR's control ball was not only excellently suited as a control device for robots, but also for the first 3D-graphics system that came onto the market at that time.
