A material handling device including gripping means for gripping and moving a workpiece along linear and angular paths from a first location to a second location. First and second cam and follower arrangements generate defined amplitudes of movement in particular degrees of freedom, and linear and angular movement mechanisms are operative to transfer movement in these degrees of freedom into movement of the gripping means and the workpiece along the linear and angular paths. A sector gear transmission is interposed in the operative connection between the linear movement mechanism and its associated cam and follower arrangement for amplifying the amplitude of movement generated by the cam and follower for transfer by the linear movement mechanism into an enlarged amplitude of movement of the gripping means and the workpiece along the linear path.
