Mecanum Wheels allow savvy robot designers to create drivetrains capable of moving in any direction using a standard chassis shape. Simply power each wheel with a different motor - by changing the directions the wheels spin, you can even make your robot move sideways!

Note: The orientation of wheels is vital when creating a Mecanum drive. Be sure that the left and right wheels are placed accordingly, and facing the right direction. See the diagram below for a correct example.
