A compact, overload-protected torque sensor design aiming for high resolution with moderate compliance — suited to force-controlled collaborative and adaptive robots.
Claims
Claims describe a torque sensor with elastic elements, signal emitter/receiver pairs, and overload protection that preserves measurement integrity under shock loads.
Technical analysis
Force-controlled arms need sensors that are accurate yet don’t shatter on collisions. Flexiv’s “moderate compliance + overload protection” framing is the practical middle ground between brittle instrumented joints and mushy soft robots.
Commercial impact
Relevant to adaptive assembly vendors competing with KUKA iiwa / UR force modes. Shows the sensing layer is still a competitive battleground, not a solved commodity.
