Abstract
Hand control devices are disclosed which provide for damping of vibrations and other unintended motion with three or more degrees of freedom. In one embodiment, a four degree of freedom damped hand control is illustrated, including a chamber filled with a viscous fluid, and a transmission which couples movement of a handle in the X, Y and Z directions and rotation in a .theta. direction about one of the axes to movements of one or more drag elements in the fluid. The hand control further includes a position-sensing and a rotation-sensing assembly for sensing the position of the handle relative to a reference frame and for generating electrical signals indicative of the position and angle.
