Reinvent the wheel!

Omni-Directional wheels roll forward like normal wheels, but slide sideways with almost no friction (no skidding during turns). Use these wheels to make your robot turn smoothly or build a holonomic drivetrain. These wheels are the same size as the VEX 4" dia. Wheels.

  • 4" Omni Wheels roll sideways with very little friction.
  • Minimize skidding during turns.
  • Build a holonomic drive.

As the name suggests, an omni-directional wheel can travel in more than one direction. When the axle spins, it behaves like a normal wheel. However, you’ll notice that there are rollers all around the outer circumference. These rollers allow the wheel to travel sideways as well!
