Adaptation method using environmental modes for biped robot with toe and heel joints on unknown uneven terrain

This research proposes an adaptation method using environmental modes for biped robots with toe and heel joints on unknown uneven terrain. The method treats information of uneven terrain as environmental modes, and derives references for controllers for adaptation. Using the proposed method, adaptation to complex uneven terrain can be achieved. Simulation and experimental results in a sagittal plane confirmed the validity of the proposed method.
