Abstract
A parallel kinematic mechanism apparatus includes a frame, a handle and an input joint that connects having at least two independent and functionally parallel paths for transmission of motion coupling the handle to the frame. A first path includes a first intermediate body connected to the frame by a first connector and to the handle by a third connector while the second path that is independent from the first path includes a second intermediate body that is connected to the frame by a second connector and to the handle by a fourth connector. The first connector and the fourth connector both allow rotation in a first rotational direction and restrict rotation in a second rotational direction and the second and third connectors allow rotation in the second rotational direction and restrict rotation in the first rotational direction.
