MIT mode
A joint control mode used in quadruped robots and collaborative robotic arms that allows a host controller to send position, velocity, feedforward torque and position/velocity gains (Kp, Kd) simultaneously, while the underlying driver runs an impedance control loop.
Timeline (last 90 days)
A freelance filmmaker spent several months developing a 6-DOF motion-control camera arm based on Robstride actuators and driven by an STM32 in MIT mode.
MIT mode is a joint control mode originally proposed by the MIT Cheetah team that allows a host computer to send position, velocity, feedforward torque, and position/velocity gains (Kp, Kd) simultaneously, with the underlying driver running an impedance control loop at a high frequency (typically 10–30 kHz).
In MIT mode, too high a Kp easily causes high-frequency oscillation, while too low a Kp causes noticeable tracking lag and gravity sag.
MIT mode typically relies on torque sensing or current estimation inside the driver, and inaccurate calibration can introduce periodic disturbances.
