1. What
Steering system are mechanisms that control the direction of movement
Goal: Control direction, maintaining stability and safety
2. Common Type
- Rack and pinion: translate rotation into linear motion

- Recirculating ball steering: worm gear and sector gear, convert rotational motion into linear motion

- Ackermann steering: used in tractors and heavy-duty vehicles, all turn smoothly

- Differential steering: use two separate motors to drive each size

- Skid steering, control the speed and direction, no turn

- Crab steering: all wheels turned in the same direction, it can move sideways

3. All in One: Four-wheel Steering
All four wheels are steered to improve the maneuverability
