Abstract

There are a biped robot gait control method and a biped robot, where the method includes: obtaining six-dimensional force information, and determining a motion state of two legs of the biped robot; calculating a ZMP position of each of two legs of the biped robot; determining a ZMP expected value of each of the two legs in real time; obtaining a compensation angle of an ankle joint of each of the two legs of the biped robot by inputting the ZMP position, a change rate of the ZMP position, the ZMP expected value, and a change rate of the ZMP expected value to an ankle joint smoothing controller so as to perform a close-loop ZMP tracking control on each of the two legs; adjusting a current angle of the ankle joint of each of the two legs of the biped robot in real time; and repeating the forgoing steps.
