Description

Technical Field

For example, in scenarios such as wilderness exploration and rescue operations, the modular tracks can be quickly changed to suit different terrains such as mud, sand, and snow, ensuring stable movement of the robot in various environments. Maintenance is also very convenient. When a track module wears out or is damaged, it is not necessary to replace the entire track; only the damaged module needs to be replaced, significantly reducing maintenance costs and time. Furthermore, the modular track structure facilitates functional expansion. Different functional modules can be added to the robot according to specific task requirements, such as adding protective devices or installing special sensors, making the robot's functions more diverse and better meeting the requirements of various complex tasks.
