Abstract

The invention belongs to the technical field of robots and aims to provide a robot and a foot structure thereof. The foot structure of the robot comprises a foot main body and an adapter bracket usedfor driving the foot main body to move, wherein the foot main body comprises an instep shell the middle part of which is connected with the adapter bracket, a bottom plate the the bearing wall of which is connected to the instep shell and covers the cavity of the instep shell, and a pad plate the buffer wall of which is connected to a connecting wall of the bottom plate and has a buffer function.According to the invention, on the premise that the production cost is not greatly increased and the foot structure is not complicated, the buffer wall of the pad plate is arranged to be a middle concave structure, so that the middle part of the buffer wall of the pad plate is not contacted with the connecting wall of the bottom plate, so that the pad plate is correspondingly deformed in the walking process of the foot main body to further enhance the absorption or buffering of the reaction impact force to the ground. According to the robot and the foot structure thereof, the absorption capacity of impact force is enhanced, and the walking posture is more stable and natural.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a robot and its foot structure. Background technique [0002] Humanoid robots, in addition to having a shape similar to humans, such as having arms, legs, torso and head, etc., have a flexible walking system and can walk on two feet like humans. As we all know, the walking speed, stability, and gait flexibility of the walking mechanism of a humanoid robot will directly affect the working ability and efficiency of the robot. In the process of walking, when the feet touch the ground, there will be an impact force, which will be transmitted to the torso through the ankle joint, resulting in the unstable gait of the humanoid robot, which is prone to shaking, and even loses balance and falls in severe cases. Otherwise, these will directly cause damage to the motors and precision devices inside the robot. Therefore, it is particularly important to alleviate the impact o...
