Stable quadruped robot locomotion is achieved by decomposing dynamics into model predictive control for the body and sliding mode control for legs.
Tracking error stays below 0.01 m for the swing leg during trotting gait tests, while roll, pitch, and yaw orientation errors remain below 0.005 rad.
Simulation of the dynamic locomotion architecture integrates quadratic programming under ground reaction forces with a digital twin in Webots.
