The integral-makers 4WD robot car chassis is equipped with 68mm rubber wheels, and controlled from a single board based on Arduino UNO R3 Motor PLUS (from Keyestudio).
Chassis top
The special Arduino board has embedded TB6612 H bridge enabling efficient control of motors directly without additional (shield) circuitry. The use of a single board with simplifies the car design, since the board comes with three pin expansion on each digital and analogue pins hence simplifying direct connection to additional sensors and actuators.
