Abstract

The invention provides a hip joint for a foot type robot and the foot type robot. The hip joint for the foot type robot comprises a first hydraulic rotary cylinder with a first shell and a first output end; a second hydraulic rotary cylinder with a second shell and a second output end; a servo motor which comprises a shell and a rotor; a first connecting frame which is provided with a first shell connecting part and a first output connecting part; and a second connecting frame which is provided with a second shell connecting part and a second output connecting part. According to the hip joint for the foot type robot jointly driven by hydraulic pressure and electric power, in roll rotation and pitch rotation, the hip joint adopts the hydraulic rotary cylinders to replace a traditional driving mode that a motor is matched with a speed reducer, the hydraulic rotary cylinder driven by hydraulic pressure can provide large torque, and therefore the use requirement of the hip joint is met; for yaw rotation, as the action range is small and the load weight is small, a rotary motor can meet the use requirement, and the overall weight of the robot is reduced.

Description

technical field [0001] The present application relates to the technical field of robots, in particular to a hip joint for a legged robot and a legged robot. Background technique [0002] Existing mobile robots are mainly divided into several types such as wheeled, crawler and footed. Wheeled robots need continuous and flat ground during movement, and it is difficult to adapt to unknown and complex road surfaces. Tracked robot motion requires a large turning radius, resulting in low flexibility. During the walking process, the legs of the legged robot are in intermittent contact with the ground, so that it can flexibly cross obstacles with a high degree of ruggedness, have a high ability to overcome obstacles, and meet the requirements of operating in complex unstructured terrain environments . [0003] Legged robots can be divided into biped robots, quadruped robots and multi-legged robots according to the number of "legs". Module, where the joint connecting the upper en...
