Mecanum Wheel Robot:

Normal Traditional wheels principle is easy you can go front and back by rotating the wheels clockwise or counter-clockwise but the this Mecanum Wheels are a little bit different. These wheels are placed in an “X” configuration. And this movement of the wheels is also different You can move the wheels in the following directions to go to different sides. These are the 12 following Combinations of movement that can be achieved from Mecanum Wheels.
