Abstract

A control lever controls movement of a system to be controlled. The control lever includes a manually operable handgrip attached to a platform. At least six connecting elements are arranged between the platform and a fixed console. Length sensors sense the length of the connecting elements, and/or force sensors sense forces acting on the connecting elements. A control unit evaluates the sensor signals and generates a control signal for controlling movement of the system. The connecting elements are be arranged in the form of a hexapod. The connecting elements may be telescoping members or rigid fixed length members.
