How the Metal Ball Caster Wheel Works
The caster wheel works using a free-moving steel ball placed inside a metal housing:
- The ball rotates freely in any direction
- As the robot moves, the caster automatically adjusts direction
- Provides support while drive motors handle movement and steering
This design ensures smooth mobility with minimal resistance.
