Arduino has emerged as one of the most favorite open source electronics prototyping platform for the DIYers all around the world. The official website of Arduino (source link below) has listed the first ever, official Arduino on the wheels. It comes with two processors, one on each of the 'motor' and 'control' boards. The motor board, as the name suggests controls the motors of the bot and the control board processes all the information it receives from sensors and then makes decision on how to operate them. Each of these boards can be programmed using Arduino IDE.
