Abstract

The invention discloses a wheel leg type humanoid robot with internal oil flowing, relates to the technical field of robots, and aims to solve the problems that when a hydraulic driving unit and a power unit are connected by adopting a rubber hose, the hose is long, the pipe arrangement is complex, and the movement flexibility of a conventional hydraulically-driven robot is influenced. The humanoid robot comprises a head, shoulders, a body, a hip pelvic bone, a first hydraulic connecting rod assembly, a second hydraulic connecting rod assembly, a third hydraulic connecting rod assembly, a hydraulic cylinder, two mechanical arms, two thighs, two shanks and two driving wheels. The head, the shoulders and the body are sequentially and fixedly connected together from top to bottom; the body ishinged to the hip pelvic bone and driven by the hydraulic cylinder, each mechanical arm is hinged to the corresponding shoulder and driven by the first hydraulic connecting rod assembly to swing leftwards and rightwards, and each thigh is hinged to the hip pelvic bone and driven by the second hydraulic connecting rod assembly to swing forwards and backwards. Each joint adopts a hose-free oil way,so that the pipeline abrasion fault is greatly reduced, and the safety and the reliability of the whole machine are improved.

Description

technical field [0001] The invention relates to a humanoid robot, in particular to a wheel-legged humanoid robot with internal oil flow. Background technique [0002] For a long time, leg-footed robots have been used as a very effective solution for rugged and complex terrain and non-continuous ground such as step ridges. Traditional wheeled or tracked robots have strong mobility on flat and continuous ground. , but the ability to pass through complex discontinuous ground is weak. Although legged robots can flexibly adapt to various complex terrains, their stability control is difficult and their walking speed is slow on flat ground. The goal of the wheel-legged composite robot is to combine the respective advantages of the wheeled robot and the legged robot, that is, the high mobility of the wheeled movement and the strong adaptability of the leg-footed movement, so that the wheel-legged composite robot has both the ability to move quickly on flat ground and the ruggedness...
