Road Racer is a high traction, high speed wheeled robot, controlled wirelessly using a 2.4 GHz PS2 joy-stick. It weighs 3.3 Kilograms and fits inside a 15 cm X 15 cm box. The racer achieves a maximum speed of  1.2 Km/hr i.e it can travel 800 times its own length in an hour. The differential drive mechanism controlled with the analog controller on the PS2 gave a fine control over the robot’s drive. The 20 KG-cm torque motors at the back and the 12 KG-cm  torque motors at the front, all rated at 12 V were powered by a 2200mAhr Lithium polymer (Li-Po) battery. Two high voltage, 2A dual full-bridge motor drivers (L298) were used to drive the motors. An Atmega328 with the Arduino bootloader was used as the main controller for the bot.
