Abstract

An electro-hydraulic circuit enabling two mechanical devices to shadow each other's movements without any direct mechanically-operative linkage between the devices. The two devices incorporate matching sets of hydraulic actuators for inducing movements of movable components of the devices. For each actuator in a given one of the devices, a system of electronic sensors and hydraulic valves, in conjunction with a central processing and control system, keeps track of the physical positions and configurations of the actuator and the corresponding actuator in the other device, and what the status of the actuators should be in relation to each other. If an actuator associated with one device is moved by an external force, a corresponding actuator in the other device moves in response to that external force, with proportionate direction, speed, and force.

IPC Classes  ?

• F15B 13/14 - Special measures for giving the operator by sense of touch the immediate response of the actuated device
• F15B 9/17 - Systems essentially having two or more interacting servomotors with electrical control means
• F17D 3/01 - Arrangements for supervising or controlling working operations for controlling, signalling, or supervising the conveyance of a product
• B25J 3/00 - Manipulators of leader-follower type, i.e. both controlling unit and controlled unit perform corresponding spatial movements
• G09B 9/00 - Simulators for teaching or training purposes
