Force-Torque Sensor

A multi-axis sensor that measures forces and torques applied to a robot's wrist, tool, or finger. Typical configurations provide 6 DOF (Fx, Fy, Fz, Tx, Ty, Tz). FT sensors enable force-controlled tasks like polishing, insertion, and safe human contact. Strain-gauge and capacitive designs dominate; MEMS variants are emerging for fingertip-scale integration.
