Robot chassis is the foundation of robot movement and an important part of the robot system. There are many types of robot chassis, which can be divided into two main categories according to the structure of the chassis: crawler and wheeled.

Crawler-type robot chassis

A crawler-type robot chassis is composed of tracks, track wheels, drive wheels, and support wheels. The advantages of the crawler-type robot chassis are that it has good passability and is suitable for complex terrain with uneven terrain, but its speed is slow and the noise is large.

Wheeled robot chassis

A wheeled robot chassis is composed of wheels, drive wheels, steering wheels, and support wheels. The advantages of the wheeled robot chassis are that it is fast and has low noise, but its passability is poor and is suitable for flat terrain.

According to the number of wheels and the driving method, the wheeled robot chassis can be divided into the following types:

  • Front wheel steering and rear wheel drive: This type of chassis has a simple structure and low cost, but has a large turning radius and poor flexibility.
  • Two-wheel drive + omnidirectional wheel: This type of chassis has a flexible structure and a small turning radius, but has a high cost.
  • Four-wheel drive: This type of chassis has good stability and passability, but the cost is the highest.

Different types of robot chassis are suitable for different application scenarios. For example, crawler-type robot chassis are suitable for industrial AGVs, military robots, etc.; wheeled robot chassis are suitable for service robots, unmanned driving cars, etc.

With the continuous development of robot technology, robot chassis have become increasingly complex and diverse. In the future, with the advancement of artificial intelligence, sensor technology, and other technologies, robot chassis will become more intelligent and flexible, and can adapt to more complex application scenarios.
