AI Technical Summary

Technical Problem

In the leg structure of existing humanoid robots, the motor is fixed to the upper ends of the thighs and calf, resulting in limited sizes of the motor and control unit, which in turn limits the running speed and load capacity of the leg structure.

Method used

A humanoid robot leg structure is designed, in which long-shaped mounting chambers are provided on the thigh and calf brackets, and the shape of the motor matches these mounting chambers, allowing the motor to be fixedly installed inside the bracket, thereby expanding the installation space of the motor.

Benefits of technology

By increasing the installation space of the motor, the running speed and load capacity of the leg structure are improved, while reducing the weight of the bracket and providing better protection, improving the overall aesthetics and simulation.

Abstract

The invention discloses a leg structure of a humanoid robot and the humanoid robot, belongs to the field of humanoid robots, and solves the problem that the sizes of a motor and a control unit are limited due to the fact that the motor is fixed to the upper ends of a thigh structure and a shank structure, according to the technical scheme, the leg structure mainly comprises a crotch, the thigh structure, the shank structure and a foot end piece; the thigh structure comprises a thigh support, two motors are installed on the thigh support, the shank structure comprises a shank support, a motor is installed on the shank support, a shell of each motor is in a long strip shape, the control unit comprises a plurality of circuit boards, the circuit boards are stacked in the shell in the length direction of the shell, and a first installation cavity is formed in the thigh support. The two motors on the thigh support are both fixed in the first installation cavity, the shank support is provided with a second installation cavity, the motor of the shank support is fixed in the second installation cavity, and a transmission unit of the motor is fixedly connected with the foot end piece. The motor mounting structure is mainly used for enabling the motor to have a larger mounting space.
