Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] As shown in FIG. 1 , the present invention includes a torso 3 , a mobile frame 1 , a center-of-mass adjustment device 2 and four robot legs 4 . The lower part of the torso 3 is provided with four robot legs 4 , and the upper part of the torso 3 is connected with the mobile frame 1 through the center of mass adjustment device 2 .

[0041]Each robot leg is composed of three leg segments (leg segment I5, leg segment II8, and leg segment III10) and a lower leg 12 (see Figure 2). The lower leg 12 is set at the lower part of the three leg segments. The longitudinal rotation joint IV14 of the torso is connected with the trunk 3 (see Fig. 3), and the joints between the leg segment I5 and the leg segment II8, the leg segment II8 and the leg segment III10, and the leg segment III10 and the lower leg 12 are all passed through the axis along the lateral rota...

Abstract

The invention relates to a moving mechanism of a hydraulic drive four-leg robot with a barycenter adjusting device, which comprises a body, a moving bracket, a barycenter adjusting device and four robot legs, wherein the lower part of the body is provided with the four robot legs; and the upper part of the body is connected with the moving bracket with the barycenter adjusting device. The moving mechanism is characterized as follows: (1) the robot has larger loading capability due to hydraulic drive; (2) the robot has higher complex terrain environment adaptability and obstacle-climbing capability as each leg has four active joints and has redundant degree of freedom; (3) the robot has better stability due to the barycenter adjusting device and no additional counter weight; and (4) the robot has simpler structure and is easily machined as the 16 active joints thereof completely adopt the same hydraulic servo oil cylinder drive. The moving mechanism is suitable for the transportation of military and civil materials, anti-terrorist equipment, field prospection and exploration, planetary detection, agricultural production and the like under the complex terrain environment.

Description

[0001] technical field [0002] The invention relates to a quadruped robot moving mechanism, in particular to a hydraulically driven quadruped robot moving mechanism with a center of mass adjustment device. Background technique [0003] At present, the commonly used mobile modes of ground mobile robots are mainly wheeled, crawler, peristaltic, crawling and walking. The wheeled mobile mechanism has the advantages of small frictional resistance and fast speed, but it is only suitable for a relatively flat ground environment, and its ability to overcome obstacles is poor. The crawler-type mobile mechanism has strong adaptability to the terrain environment, and can climb over obstacles, climb stairs, and cross trenches, etc., but the transmission efficiency is low. Creeping, crawling and walking are all bionic movement methods that imitate animals. They have strong adaptability to the terrain environment and can walk on most ground environments, and the walking method has the f...
