Cover Story: Design solutions of force-torque sensors can be conceived by using many types of connections or components; however, there are only a few sensors designed using cable-driven systems. In this paper, a new cable-driven model for under-actuated force-torque sensing mechanisms is proposed, simulated, and tested, underlining the novelty of using cables for force-torque sensing. The results confirm that the new proposed model can be used for force-torque sensing mechanisms in micro- and macro- applications where under-actuation is a fundamental requirement, as in robotic surgery. The innovative model is validated with two different test benches, opening new challenges in the design and development of under-actuated force-torque transducers. View this paper
