  Unlike many tabletop "Cobot" ("collaborative robot") robotic arms which use BLDC / frameless DC motors and measure the current needed for a motion, the LSS-P actuators use standard sized and industry proven bipolar stepper motors. These motors provide high torque at low speeds, but operate at a set current and therefore do not have a direct way of measuring the torque.
