Push Recovery of a Position-Controlled Humanoid Robot Based on Capture Point Feedback Control
, 2017 In this paper, a combination of ankle and hip strategy is used for push recovery of a position-controlled humanoid robot. Ankle strategy and hip strategy are equivalent to Center of Pressure (CoP) and Centroidal Moment Pivot (CMP) regulation respectively.
