I am developing a robot platform for children for educational purposes. My aim is to build a sub 100$ bot with arduino brains. I myself is a good programmer, and if I were to do it for myself, I would use an ARM or a better platform, but I have to constraint this project with arduino.
I have already designed some parts, and I have access to a 3d printer, so it is going all well. I already have a servo/sharp IR sensor scanner, and currently I am using a tamiya tracked vehicle for platform.
