Weird Robot car moves in Four Directions

This tiny machine with the innovative wheels, created for perfect parallel parking.   Watch the Mecanum wheel mobile Arduino robotics car in the video…

A four wheel drive vehicle made to move in any direction, designed for hobbyists, programmable with the open soure Arduino language.

This Mecanum wheel mobile Arduino robotics car can be made to move in any direction and turn by varying the direction and speed of each wheel. Moving all four wheels in the same direction causes forward/backward movement, running left/right sides in opposite directions causes rotation, and running front and rear in opposite directions causes sideways movement. The platform rear wheels are mounted in a particular way, so that the suspension structure ensures that all four wheels can adhere to the ground, even when the ground is uneven.
