AI Technical Summary

Technical Problem

In existing technologies, the waist rotation and lower limb posture control of humanoid robots are independent of each other, which leads to the shift of the torso's center of gravity and the lag of the lower limb posture during dynamic movement, resulting in insufficient balance maintenance and easy posture swaying or tipping.

Method used

By employing a mechanical linkage structure and an electrical signal feedback coordinated control method, the robot achieves synchronous adjustment of torso and waist rotation and lower limb posture through a rotary drive motor, a reduction mechanism, multi-dimensional sensors, and a synchronous controller. The robot uses rotation angle, torque, and three-dimensional force sensors to adjust the lower limb posture in real time, ensuring the robot's balance and stability during rotation.

Benefits of technology

It achieves coordinated adjustment of the torso and lower limbs, improves the robot's balance stability and control precision in dynamic motion, enhances its adaptability to complex terrain and diverse tasks, and reduces joint wear and energy consumption.

Abstract

The invention relates to the technical field of humanoid robots, and discloses a humanoid robot trunk and waist rotation linkage adjusting device which comprises a trunk lower mounting plate, a center rotating shaft, a middle connecting support, a left hip connecting seat and a right hip connecting seat. The trunk lower mounting plate is horizontally arranged at the bottom of the robot trunk, the center rotating shaft is arranged in the vertical direction, the upper end of the center rotating shaft is coaxially and fixedly connected with the lower surface of the trunk lower mounting plate, and the middle connecting support is arranged in the middle of the center rotating shaft in a sleeving mode and rotationally connected with the center rotating shaft. The left hip connecting base and the right hip connecting base are symmetrically arranged at the lower ends of the two sides of the middle connecting support. Synchronous adjustment of trunk waist rotation and lower limb postures is achieved through a mechanical linkage structure, the lower limb postures can be adjusted in time in the waist rotation process, center-of-gravity shift caused by trunk rotation is effectively counteracted, and the balance stability of the robot in a dynamic motion scene is improved.
