Abstract

The invention belongs to the technical field of a humanoid service robot and particularly relates to a humanoid robot and a leg structure thereof. The leg structure is characterized in that the installation position of a knee joint driving piece with large weight is raised to a thigh part, the power of the knee joint driving piece is transmitted to a shank part through a knee joint transmission assembly to drive the shank part to swing, so the rotational inertia of the thigh part is reduced, and the power required by the knee joint between the thigh part and the shank part is effectively reduced. The humanoid robot adopts the leg structure, and the rotational inertia of the leg structure of the humanoid robot is reduced so that the power required by knee joints is effectively reduced.

Description

technical field [0001] The application belongs to the technical field of humanoid service robots, and in particular relates to a humanoid robot and its leg structure. Background technique [0002] In the field of robotics, traditional humanoid robots have problems such as low center of gravity, heavy weight, and high moment of inertia. Reducing the inertia of the legs is of great help to the control of the robot. Reducing the inertia can also reduce the torque required by the robot. Most of the joints of existing humanoid robots are in series configuration, which leads to heavy legs and large moment of inertia. Since the calf part is at the end of the whole leg, it has the greatest influence on the moment of inertia. How to reduce the weight of the leg part is very important. The knee joint has the largest torque among the legs of a humanoid robot. In order to preserve the stability of the robot, the legs usually have to walk with their knees bent, which also causes more lo...
