Summary:High precision apparatus is described which can be arranged and used in the form of manipulators, actuators, position transducers or force transducers, having four to six degrees of freedom. A movable platform, to which the object subjected to movements or forces is fixed, is connected to a base of the apparatus by six links in parallel. These links comprise articulated kinematic units each comprising a deformable parallelogram and an articulated transmission device connecting the parallelogram to the platform. The parallelogram is associated with a position sensor and an electromagnetic transducer, such as a linear motor.
