Its hallmark is a patented steel cable transmission system which enables high forces and high rigidity in the three orthogonal axis of translational motion. The motors are mounted on the base of the mechanism, so that only light linkage elements move with the handgrip. . The compelling effect of haptic feedback is demonstrated in a virtual building block simulation shown below. The user can pick and place different objects in a virtual assembly.
Force feedback enforces physical constraints, preventing the blocks from impeding on each other. .
