Robot-Human Control Interactions In Mining Operations

A control technique is described for enhancing the efficiency of materials handling and other mining operations. The concept involves human-operator and robotics control interactions to assist in mining operations. Many mining tasks require a human operator to coordinate the motion of several machine links by simultaneously manipulating multiple joysticks or other control devices. The new control architecture allows for automatic coordination of multiple machine joints. The machine movement may follow a computer-optimized, learned coordination pattern, while the operator still retains the master control of the overall trajectory and velocity parameters. Examples are described for a surface mining front shovel.
