HiTechnic Rotacaster 2-pack

The HiTechnic Rotacaster multi-directional wheel is perfect for creating robots that can move in any direction. Your robot can go forward, backward and sideways or any direction in between by using three or four Rotacaster wheels. The Rotacaster wheel is also an excellent alternative to a caster wheel since it can roll in any direction. With a compatible cross axle hub these wheels can be easily built into your MINDSTORMS and Technic models. The wheel is manufactured with low friction rollers to ensure easy movement in any direction. Note: Photo shows a single wheel. This 2-Pack comes with two Rotacaster wheels.
