Abstract
A hand controller (10) is provided with which an operator can simultaneously control several degrees of freedom of a mechanism, for example a slave arm (18), single handedly. An operator's handle (12) is connected by four links serially arranged between the handle and elements (50, 48, 46, 42) to a platform (32), these links permitting rotation about three axes (A, B, C) and linear displacement towards and away from the platform (axis Z). The platform is connected by three parallel non-telescopic legs (34) to a base (30) so that the platform (32) (and so the handle 12) can be moved in directions (X and Y) perpendicular to the Z axis. Force and torque feedback may be provided to all motions of the hand controller (10).
Claims2
A hand controller whereby an operator can control movements of a mechanism, the controller comprising a base, a support frame connected to the base by three parallel non-telescopic link arms with universal joints at each end so as to allow displacements of the frame relative to the base, and an operating handle connected by four serially arranged links to the support frame, the said links respectively allowing rotation of the handle about three independent axes and linear displacement of the handle relative to the support frame.
