Problems solved by technology

At present, two-wheeled robots are mainly driven by motors. On the one hand, the driving structure is relatively complicated and takes up a lot of space. On the other hand, the noise is relatively large, causing noise pollution to the indoor environment and interfering with people's normal work and rest.

Abstract

The invention discloses a two-wheeled robot actuated by SMA springs. Compared with traditional motor drive, SMA spring actuating is adopted in the two-wheeled robot actuated by the SMA springs, a cross-shaped structure composed of four cylindrical pipes is arranged in each wheel of the two-wheeled robot, the SMA springs are arranged in the cylindrical pipes, one ends of the SMA springs are fixed to a wheel centroid, the other ends of the SMA springs are connected with cylindrical heavy objects, and the cylindrical heavy objects can be exactly placed in the cylindrical pipes and can slide in the cylindrical pipes. The SMA springs have characteristics that the SMA springs can be extended during heating and can be restored during not heating, when heating is carried out, the SMA springs extend to drive the cylindrical heavy objects to perform displacement in hollow pipes to deviate from the wheel centroid, so that wheel gravity center is changed, and the wheels are rolled.

Description

technical field [0001] The present invention relates to the technical field of two-wheel robots, and more particularly, the present invention relates to a two-wheel robot actuated by SMA springs. Background technique [0002] Two-wheeled robot is one of the hot research technologies in robotics in recent years. Because of its relatively simple structure, free movement, and free shuttle in various environments and spaces, it has been widely used in many fields. At present, two-wheeled robots are mainly driven by motors. On the one hand, the driving structure is relatively complicated and takes up a lot of space. On the other hand, the noise is relatively large, causing noise pollution to the indoor environment and interfering with people's normal work and rest. [0003] Using SMA spring as the driver, this type of driver has the advantages of large output displacement and simple electrothermal drive structure. SMA (shape memory alloy) spring has the characteristics of being a...
