Abstract

A Tape Muscle is described where multiple tape loops are independently driven by synchronized grasp and pull actions from a tandem of Clamp, Clamp & Drive modules. Each tape loop is elastically bent, with its open ends threaded through individual passageways in both modules. Tape loops are nested inside each other with all tape open ends on the same side. Each loop moves its open ends in equal, opposite directions, while the loop position remains fixed. Tape movements do not interfere with each other. The open ends of each loop attach to a shared appendage, which is pulled back and forth using tensile forces. Drive and hold forces use small angle flexure bending mechanical advantage and high force density electrostatic induction methods. Tape speed results from high frequency clock speed and novel hand-off methods. Governing equations, design details and performance estimates are provided.
