Bionic body mechanism capable of realizing multi-directional bending

Abstract

The invention relates to a bionic body mechanism capable of realizing multi-directional bending. The bionic body mechanism comprises a front body assembly, a driving assembly, a bionic spine assembly and a back body assembly, wherein the front body assembly and the back body assembly adopt frame structures; the driving assembly comprises six motors which drive six fixed-length connecting rods respectively and are circumferentially distributed around the bionic spine assembly, and the driving assembly is fixedly connected with the front body assembly and the back body assembly through screws; the two ends of the bionic spine assembly are fixedly connected with the front body assembly and the back body assembly through screws respectively. The bionic body mechanism capable of realizing multi-directional bending simulates the body structure of four-footed organisms, can realize lateral bending and vertical bending, has a good bionic property and bending flexibility and overcomes the defect that traditional robot body structures cannot realize flexible and dynamic bending.

Description

technical field [0001] The invention relates to a bionic body mechanism capable of bending in multiple directions, which can be used for the body of a quadruped bionic robot and belongs to the field of bionic robots. Background technique [0002] The body mechanism of a quadruped robot is an important factor affecting its mobility and stability. [0003] The body structure of quadruped robots currently developed mostly adopts a rigid overall structure. The integral rigid body ignores the role of the body mechanism in dynamic high-speed movement and in-situ steering. When the robot turns to avoid obstacles, it can only adjust the gait. As a result, the steering radius is relatively large, lacks flexibility and flexibility, and it is difficult to achieve flexible steering similar to the bending of a quadruped body. On the other hand, when the biological body is moving at different speeds, the body can be bent up and down to different degrees to adapt to different moving speed...
