D. J. Braun, J. E. Mitchell, and M. Goldfarb, Actuated dynamic walking in biped robots: Control approach, robot design and experimental validation, IEEE-RAS International Conference on Humanoid Robots, Paris, FR, pp. 237–242, December 2009.
This paper presents and experimentally validates a control strategy for actuated dynamic walking in biped robots. Instead of relying on trajectory tracking, the method applies state-dependent torques generated by low-gain spring-damper elements to encourage natural, patterned motion. A seven-link biped robot with backdrivable actuators was designed to allow passive leg motion, enabling human-like gait. Experimental results confirm that the approach produces stable and natural dynamic walking.
Why it matters: Achieving efficient, human-like walking in robots requires moving beyond rigid trajectory tracking. This work demonstrates both the theory and experimental validation of a control approach that leverages natural dynamics, laying the groundwork for more agile and energy-efficient humanoid robots.
