Novel Twisting String Actuation for Robotic Grippers

A twisting string actuation (TSA) transmission uses wire(s) to transmit power from a motor on one side to a load on the other side. When the motor rotates the wires are twisting themselves, and thus provide a pulling force on the load. The aim of the project is to add to an existing TSA unit previously designed in out lab some design refinements to improve performances. The first of which is a variable radius rod which changes the speed rate and the output force. The application will be to drive a two-finger robotic gripper.
