Problems solved by technology

However, most of the pneumatic artificial muscles have a diameter of 10-40mm. When inflated, the muscles harden and expand radially, and there are heavy rigid air-leakage parts at both ends. It is difficult to densely install in the robot body to obtain the same performance as biological muscles The advantages of redundant drive mechanisms and light weight of pneumatic artificial muscles have not yet been fully utilized

Embodiment Construction

[0024] Below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in further detail:

[0025] like figure 1 As shown, a biomimetic body with variable stiffness driven by quasi-biological muscle fibers is composed of a front frame I, a rear frame V, a bionic spine III, a bionic ligament group IV, and a pneumatic muscle fiber group II. The front frame I, the rear frame Frame V is a space frame structure, and the two are connected as a whole by a bionic spine III; the four ligaments of bionic ligament group IV pass through the bionic spine III and are distributed in a circle around the bionic intervertebral disc 3, and the two ends are respectively fixed on the front frame I, On the rear frame V; the pneumatic muscle fiber group II has a total of eight groups, of which the two ends of the six groups are integrally sealed, and are respectively fixed on the front frame I and the rear frame V through the tendons 17, and one end of the...

Abstract

The invention relates to a bionic body with variable stiffness driven by biological muscle fibers, and belongs to the technical field of bionic robots. The invention includes a front frame, a rear frame, a bionic spine, a bionic ligament group and a pneumatic muscle fiber group. The bionic spine is composed of a number of bionic vertebral units, thoracic and lumbar vertebrae. Each bionic vertebral unit includes a bionic vertebra and a bionic intervertebral disc. The bionic spine is fixedly connected to the front frame and the rear frame through screws. The pneumatic muscle fiber group is composed of several pneumatic muscle fibers, which are respectively tied to the anterior frame, the posterior frame and the thoracic ribs through tendons. The invention can realize the lateral bending and up-down pitching bending movements of the body, has the characteristics of light structure, flexible movement, flexibility, good bionic effect, etc., and can improve the dynamic movement performance of the robot in the unstructured environment.

Description

technical field [0001] The invention relates to a bionic body with variable stiffness driven by biological muscle fibers, which can be used for a quadruped bionic robot and belongs to the technical field of bionic robots. Background technique [0002] The quadruped bionic robot is in contact with the ground point during the movement process, which can adapt to the complex terrain environment and has broad application prospects. At present, the body of the quadruped bionic robot mostly adopts a rigid overall structure, which cannot make full use of the important functions of the flexible body of the quadruped mammal. The quadrupedal mammalian spine structure and the muscular system work together, on the one hand, the body can bend flexibly and realize the function of turning in situ; Store and transfer energy. [0003] Pneumatic artificial muscles are widely used in wearable robots and bionic robots because of their similar flexibility and contractility to biological muscle...
