The selection and use of robot wheels depend specifically on the robot's purpose, environment, and required maneuverability. Here are some common robot wheel configurations:
1. Four wheel differential drive: This is a common configuration that includes four independently driven wheels. This design provides good maneuverability and stability, and the robot can move in various directions. Robots with four-wheel differential drive are usually able to achieve translation and rotation.
2. Three omnidirectional wheels: The configuration of three omnidirectional wheels allows the robot to achieve omnidirectional movement on a plane, including forward and backward, left and right, and rotation. This design is particularly suitable for situations that require precise movement in small spaces, such as warehouse robots or service robots.
3. Six wheel or eight wheel off-road chassis: used for robots that need to move on uneven terrain, such as detectors, patrol robots, etc. These chassis typically use six or eight large-diameter wheels to provide better passability and stability.
4. Double wheel or single wheel inverted pendulum: Some robots adopt the design of double wheel or single wheel inverted pendulum, which achieves balance and maneuverability through precise control of the wheels. This design is common in some humanoid robots and toy robots.
5. Chain or track chassis: When moving in uneven or obstructed environments, robots may use chain or track chassis. This design provides better passability and is suitable for various terrains.
