Intro
For this tutorial we will be using the Explore Robo kit. You may go ahead and download the schematics and other details from the link.

This is a very simple type and you can easily hack it. The controller board also has a atmega8 MCU with Arduino bootloader, hence we can code it from the Arduino IDE
