Abstract
An arm structure for use in an articulated mechanism such as an industrial robot comprises a plurality of links operatively interconnected by articulations having respective actuators and actuatable by the actuators under a fluid pressure. Each of the links comprises a hollow cylindrical casing and an accumulator comprising a pipe extending axially through the casing and a rubber tube disposed around the pipe. The tube is radially inflatable by the pressure of the fluid supplied into the space between the pipe and the tube through small holes defined in the wall of the pipe and the cylindrical casing is pressurized.
