Problems solved by technology

From a biological point of view, the current difference between quadruped robots and quadruped animals is that their spines play different roles; however, although domestic quadruped robots are diverse, they are too single in terms of spine design. There are major limitations in connection

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

[0024] Such as figure 1 The spine of a bionic robot shown includes an electromagnet 1 , a spherical thin shell 2 , a stud 3 , an elastic rod 4 , an elastic rod 5 , a spherical stud 6 , and a permanent magnet 7 .

[0025] The spine of the above-mentioned bionic robot includes several spine units with the same structure.

[0026] In each spine unit, the spherical thin shell is a thin-walled structure with an inner cavity, and the outer surface of the spherical thin shell is provided with a protrusion that can be fixed with an elastic rod, so as to maintain the shape of the spine when it is at rest. Provides a fulcrum for force when bending. The inner surface of the housing is attached with a sheet-shaped electromagnet, which can provide a magnetic field to drive the permanent magnet to rotate when it i...

Abstract

The invention relates to a bionic robot. The invention aims to provide a bionic spine of a quadruped robot, which can be flexibly bent so that the quadruped robot can adapt to complex terrains more flexibly and conveniently, and the bionic spine of the quadruped robot has the advantage of being reliable in work. According to the technical scheme, the bionic robot spine comprises a controller; the spine is characterized by comprising a plurality of spine units which are arranged in sequence and are connected pairwise, each spine unit comprises a spherical thin shell with an opening, a plurality of electromagnets fixed on the inner wall of the spherical thin shell, a spherical column head which wraps a permanent magnet and can be positioned in the spherical thin shell in a rolling manner, and an elastic column rod of which one end is connected with the spherical column head and the other end extends to the outside through the opening and is connected with the adjacent spherical thin shell; and the spine further comprises an elastic rod and batteries, wherein the elastic rod is sequentially connected with the spherical thin shells so as to ensure the relative movement of the spherical thin shells and the spherical column heads, and the batteries are connected with the electromagnets through the controller respectively.

Description

technical field [0001] The invention relates to a bionic robot, in particular to a spine of a bionic robot. Background technique [0002] In recent years, with the improvement of bionic technology, the development of bionic robots is also faster and faster, and the requirements of scientific research for bionic robots are also increasing. Bionic robots can replace humans to reach places that are difficult to reach, thereby collecting data that could not be collected before. For analysis, and this also puts forward higher requirements for the performance of the bionic robot itself. [0003] After research and investigation, it is found that the quadruped robot runs on four legs, and its spine plays a role in connecting small units and transmitting force and direction. From a biological point of view, the current difference between quadruped robots and quadruped animals is that their spines play different roles; however, although domestic quadruped robots are diverse, they ar...
