Abstract

The invention belongs to the technical field of robots, and particularly relates to a foot-waist coordination gait planning method and device of a robot, a computer readable storage medium and the robot. The method comprises the steps that the foot posture angle of the biped robot is obtained, and the ankle joint position compensation amount of the biped robot is calculated according to the foot posture angle; acquiring a waist attitude angle of the biped robot, and calculating hip joint position compensation amount of the biped robot according to the waist attitude angle; calculating a hip-ankle position vector of the biped robot, wherein the hip-ankle position vector is a position vector from a hip joint to an ankle joint; compensating the hip-ankle position vector according to the anklejoint position compensation amount and the hip joint position compensation amount to obtain a compensated hip-ankle position vector; and inverse kinematics analysis is carried out on the compensatedhip and ankle position vector to obtain the joint angle of the biped robot, so that effective foot and waist coordination is realized, the accuracy of actions is improved, and various complex actionsare completed.

Description

technical field [0001] The present application belongs to the technical field of robots, and in particular relates to a robot foot-waist coordination gait planning method, device, computer-readable storage medium and robot. Background technique [0002] The anthropomorphic bipeds of the humanoid robot can not only walk on flat ground, but also walk in complex environments, for example, up and down steps or slopes, cross obstacles, and move on uneven ground. The typical biped walking gait is based on the sole of the foot and the ground (regardless of the influence of the attitude angle of the foot when it is in contact with the ground), and then solves the inverse kinematics to convert the planned motion trajectory into the desired joint Angle, and controlled by the joint servo drive to achieve trajectory tracking. This method fails to fully consider the changes in the posture of the feet and the waist, and cannot perform effective foot-waist coordination. The accuracy is lo...
