Abstract
A method for controlling gait of a biped robot includes: collecting a lateral center of mass (CoM) speed and a lateral CoM position of the biped robot when the biped robot walks in place; calculating phase variables of virtual constraints corresponding to the CoM of the biped robot in a first phase and a second phase according to the lateral CoM speed and the lateral CoM position; constructing motion trajectory calculation equations for the biped robot based on the phase variables corresponding to the first phase and the second phase, respectively; and finding inverse solutions for joints of the biped robot using the motion trajectory calculation equations to obtain joint angles corresponding to each of the joints of the biped robot to realize gait control.
