A method for planning stair-climbing torque based on multi-pose information fusion first acquires the pose information of the lower limbs when climbing stairs through a pose sensor. Then, based on the pose information of the lower limbs, the motion information of the human lower limbs when climbing stairs is obtained. Next, kinematic calculations are performed on the entire lower limb pose data to obtain the motion information of the human lower limbs, and then the human motion trajectory is obtained. The vertical velocity of the ankle joint is used as the discrimination criterion. When the velocity is greater than a predetermined threshold, an assist phase torque is output and the device outputs torque to follow the human body according to the interactive force data. When the velocity is less than the predetermined threshold, a follow-up phase torque is used and no assist phase torque is output. Finally, the motion controller MCU outputs torque and the knee joint motor executes it. This invention patent utilizes the ankle joint, which has good periodicity and strong noise resistance, to recognize the motion state and improve the stability of state identification. By filtering the human-computer interaction force and the output torque, the accuracy of torque is improved while optimizing the user comfort of the exoskeleton wearer.
