Abstract
A method for controlling walking of a robot includes: determining a stance of the robot, in response to the robot being in a single-leg stance, determining a rotational angle of each of the joints, and calculating a value of a torque produced by a force of gravity acting on the robot about each of the joints; in response to the robot being in a double-leg stance, calculating a position of a projection of a center of mass of the robot on a surface where the robot stands, and calculating a value of a torque produced by a force of gravity acting on the robot about each of the joints according to the position of the projection; obtaining a feed-forward current of each of the joints; and applying the feed-forward current of each of the joints to a corresponding actuator of this joints.
