Four-foot bionic robot with flexible spine

Abstract

The invention relates to the field of robots, the invention relates to a bionic robot, in particular to a four-foot bionic robot with a flexible spine. The robot comprises the flexible spine and a plurality of multi-degree-of-freedom machine legs fixed to the flexible spine. The flexible spine comprises a main skeleton, an auxiliary skeleton and buffer springs which are each of a rectangular structure. A supporting part is mounted in the end part of the main skeleton; a plurality of rotating motors are mounted on the connecting part; the axes of output shafts of all the rotating motors are collinear; a connecting frame is mounted at the end part of the secondary skeleton; the connecting frame is fixedly connected with the output shafts of all the rotating motors; the two ends of each buffer spring are fixedly connected with the end face, where the bearing part is located, of the main skeleton and the end face, where the connecting frame is located, of the auxiliary skeleton correspondingly. The robot is high in bearing capacity, high in stability and simple in structure, certain bearing and flexibility are guaranteed, the flexible spine ground robot can better meet the speed requirement, and the moving capacity of the robot in an extreme environment is improved.

Description

technical field [0001] The invention relates to the field of robots, in particular to a quadruped bionic robot with a flexible spine. Background technique [0002] In recent years, the internal procurement, production, and sales processes of manufacturing companies have been accompanied by the flow of materials. More and more manufacturing companies have paid more and more attention to logistics automation while paying attention to production automation, intelligent sorting systems, and stacking robots. , The application of automatic roller system is becoming more and more popular. Efficient and high-speed logistics quadruped bionic robots can greatly improve the current logistics industry's obvious bloated body, slow speed, and low efficiency problems, and optimize trajectory and speed. In addition, modern warfare is more inclined to compete with thermal weapons, large heavy weapons, and high-tech technologies. Transportation has become a problem that plagues the military....

The disadvantage is that the coordinated control of the legs is more complicated and the carrying capacity is smaller

[0004] At present, the most representative robot is Boston Dynamics’ Big-Dog and other robots, as shown in the picture below. Its outstanding athletic ability and strong terrain adaptability enable it to adapt to mountains, slopes, jungles, ice, snow, etc. For complex terrain, the spine of the existing quadruped bionic robot is integral and relatively rigid, which limits the movement speed of the robot. For extreme working environments, the overall structural center of gravity of the spine remains unchanged, allowing the quadruped bionic robot to move in extreme working environments the effect is not good
