MINDSTORMS Robot Inventor Mecanum Wheels drives in EVERY Direction

Watch how I connected four Mecanum wheels to the four motors of the LEGO MINDSTORMS Robot Inventor 51515 kit. The result is an amazing car that can drive in every direction and turn around its axis. Here’s how to assemble and program the Mecanum wheels.

Mecanum wheels are a lot like omni-wheels. The omniwheels are also known as rotocasters or holonomic wheels. An Omniwheel has no lateral grip and would go everywhere. But Mecanum wheels are different. Unlike rotocasters, the Mecanum wheels have diagonally oriented rolls. If you push a wheel like that sideways, it starts to rotate! Some people call this type of wheel the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon. Ilon came up with the concept while working with the Swedish company Mecanum AB.

I used these wheels:
