3-D Underactuated Bipedal Walking via H-LIP Based Gait Synthesis and Stepping Stabilization

Xiaobin Xiong et al.

Summary: This article presents a hybrid-linear inverted pendulum (H-LIP) based approach for synthesizing and stabilizing 3-D foot-underactuated bipedal walking. The H-LIP captures the essential components of the underactuated and actuated part of the robotic walking, and the robot walking gait is directly synthesized based on it. By approximating the step-to-step dynamics, a H-LIP based stepping controller provides desired step sizes to stabilize the robotic walking, resulting in dynamic and stable walking. The approach is evaluated on the 3-D underactuated bipedal robot Cassie, demonstrating versatile and robust dynamic walking behaviors.

Robust Stabilization of Periodic Gaits for Quadrupedal Locomotion via QP-Based Virtual Constraint Controllers

Randall T. Fawcett et al.

Summary: This letter presents an optimization-based nonlinear control methodology for stabilizing quadrupedal locomotion using virtual constraints and control Lyapunov functions in the context of quadratic programs. The study provides sufficient conditions for the differentiability of the controller and addresses the robust stabilization problem using Poincare sections analysis and input-to-state stability. The proposed controller is validated numerically and experimentally on a quadrupedal robot, demonstrating robust stability against external disturbances and unknown payloads.
