Abstract

The invention belongs to the technical field of robots, and particularly relates to a mass center pose estimation method and device, a computer-readable storage medium, and a robot. The method comprises: obtaining a waist measurement posture of the robot and all joint angles of supporting legs; calculating ankle postures of the supporting legs according to the waist measurement posture and the joint angles; compensating preset initial ankle positions according to the ankle postures to obtain ankle positions of the supporting legs; calculating a waist pose of the robot according to the ankle poses of the supporting legs and all the joint angles; and calculating a mass center pose of the robot according to the waist pose. According to the method, the ankle poses are fully considered in the calculation process of the mass center pose, so that the situation of sole overturning can be effectively processed, and the result accuracy is greatly improved.

Description

technical field [0001] The present application belongs to the technical field of robots, and in particular relates to a centroid pose estimation method, device, computer-readable storage medium and robot. Background technique [0002] Gait planning and balance control of humanoid robots are hot topics in the field of robotics. Both the gait planning algorithm and the balance control algorithm are based on feedback control. The premise of feedback control is to obtain the accurate feedback value of the robot state, and there are usually two types of feedback value acquisition of the robot state: one can be obtained directly from the sensor, and the other Classes need to obtain other indirect robot states through other sensors, and then perform kinematics and dynamics calculations to obtain robot states. The process is more complicated and difficult. [0003] For example, centroid pose estimation is usually a difficult point in gait planning and balance control of humanoid ro...
