A technique is described whereby a compact pulley/cabling system is provided in place of coiled cables and hoses in robotic mechanisms with telescoping slides requiring long travel. A typical electric drive robot (EDR) utilizes a three-slide telescoping arm so as to provide the required extension. Attached to the arm is a three-axis wrist and a pneumatic gripper which requires a cable with a large number of conductors for power and signal transmission. The power and signal cables must be individual cables so as to prevent electrical noise interference. Also, pneumatic hoses are required to operate a double-acting air cylinder of the gripper. In the prior art, the cables and hoses were coiled so as to provide for telescoping movement of the arm.
