A fast-walking bipedal robot

Abstract

The invention discloses a bipedal robot capable of quickly walking. The bipedal robot comprises a counterweight assembly, a linear motor, a motor shaft, a motor seat, a telescopic fixing rod, left and right connecting rods, left and right thighs, left and right crura and left and right rotary air cylinders, wherein the linear motor is used for driving the left and right connecting rods to swing so as to drive the thighs hinged to the motor seat to swing back and forth; the left and right rotary air cylinders are used for driving the left and right crura to swing according to the relative position between the motor shaft and the motor seat to enable the supporting legs of the robot to be longer than the swinging legs of the robot so as to enable the robot to walk. Compared with the prior art, the bipedal robot has the advantages that the thighs are simultaneously driven to swing through the linear motor only, so that coordinated movement is facilitated; the control is convenient and the control precision is high; the structure is simple and compact and the stability is good; quick movement can be realized and the walking efficiency is relatively high; the robot is especially suitable for occasions with quickness and stability requirements.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to a fast-walking biped robot. Background technique [0002] At present, biped robots have developed into a research hotspot. Different from rolling robots, biped robots do not contact the ground continuously during movement. In some cases, such as fields, they can better adapt to the needs of the environment. Biped robots have good environmental adaptability and can replace humans in tedious or dangerous tasks, such as welding, assembly, housekeeping, emergency rescue, nuclear power plant maintenance, and planetary exploration, so they have broad application prospects. [0003] With the development of science and technology, biped robots have made great progress in imitating human actions and communicating with people. Among them, the typical representatives are QRIO of Sony Corporation of Japan and NAO of Aldebaran Corporation of France. Chinese patent document CN101121424A disclo...
