Abstract

The invention relates to a closed chain rolling robot driven by the shape memory alloy, the robot comprises a plurality of connecting rod structure modules, and the connecting rod structure modules are connected end to end to form a closed chain structure; a shape memory alloy wire is connected between every two adjacent connecting rod structure modules, each shape memory alloy wire can be electrified to contract to drive the corresponding connecting rod structure module to swing, and each connecting rod structure module can reset to drive the corresponding shape memory alloy wire to restore; and the shape memory alloy wire is used for driving the closed chain structure to roll over. According to the invention, the memory effect characteristic of SMA is fully utilized, the driving of each connecting rod structure module is realized, the size is smaller, the body is softer, the obstacle crossing ability is better, the structure is simpler, and the operation is more stable.

Description

technical field [0001] The invention relates to the technical field of intelligent mobile robots, in particular to a closed-chain rolling robot driven by a shape memory alloy. Background technique [0002] Mobile robot technology is an emerging product integrating machinery, computer, communication, sensor, biology, bionics and other disciplines, and is an important member of the intelligent robot family. Mobile robots can be divided into wheeled, tracked, legged and spherical robots according to different motion forms. Different motion forms endow it with different performance and application occasions. However, the power of the traditional drive method is relatively low. In recent years, scholars have been studying how to apply smart material drives to various drives. The shape memory alloy driver utilizes its own shape memory effect and has the advantages of high deformation and high functional density, so it is widely used in various engineering fields. [0003] There ...
