News editors obtained the following quote from the background information supplied by the inventors: “BACKGROUND ART “Mechanical transmission systems that allow motions and forces to be transmitted over a distance are known. Examples include automotive transmission units that transmit engine forces to the wheels of an automobile, bicycle cables that trans mit the rider’s grip force to the brakes, and hydraulics that drive the links of an excavator arm. “Mechanical transmissions can also be used to drive the links of robot arms. In a hydraulic robot arm, each joint is actuated by a piston inside a hydraulic cylinder. Hydraulic fluid fills the cylinder on each side of the piston and can pus hit in either direction. The pressure drop across the piston and hence the piston force is regulated by electronically controlled valves at the base of the robot.
