Abstract

A man-machine interface is disclosed which provides force information to sensing body parts. The interface is comprised of a force-generating device (106) that produces a force which is transmitted to a force-applying device (102) via force-transmitting means (104). The force-applying device applies the generated force to a sensing body part. A force sensor associated with the force applies device and located in the force applicator (126) measures the actual force applies to the sensing body part, while angle sensors (136) measure the angles of relevant joint body parts. A force-control unit (108) uses the joint body part position information to determine a desired force value to be applies to the sensing body part. The force-control unit combines the joint body part position information with the force sensor information to calculate the force command which is sent to the force-generating device.
