Hydraulic control system with tactile force and position feedback

摘要

An apparatus for translating the movements of a portion of an operators anatomy residing in communication with an input fitment into hydraulic signals thereby directing the motion of a machine member moved by a hydraulic driver with natural motion of the operator. The subject apparatus also transfers the motion of the machine member under control to a proportional motion of the control fitment, giving the operator a tactile sense of the direction and magnitude of the motion being executed by the machine member under the control of the apparatus. Additionally, the subject apparatus conveys a force proportional to that experienced as a resistance to movement by a machine member under the control of the apparatus to the operator through the control fitment, giving the operator a tactile sense of the resistance opposing the machine operation being directed by the operator.
