Robust Bipedal Walking with Closed-Loop MPC: Adios Stabilizers
Résumé
We present a new walking control scheme based on the extended dynamics of the inverted pendulum. Our scheme includes re-planning of the steps locations and steps timings, feet force control, and a walking pattern generation that is closedloop thanks to feedback in the state of the real humanoid robot pendulum (CoM position/speed and ZMP). No additional control policy is used to maintain static and dynamic balance of the humanoid. We experimented this framework on five different humanoid robots over multiple disturbances including sudden pushes during walking or in a static state and by achieving locomotion over uneven and compliant grounds.
