Well everyone in the Microcontroller contest at instructables recieved a 50% off code for this robot https://www.robotshop.com/dfrobotshop-rover-tracked-robot-basic-kit.html
I am not going to use mine. 50% off means you still have to pay $45 for it. I will give this code away to some one who will actually spend the $45 to buy the robot. I do not want to give it to someone else who will not use it.
