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