That´s my first robot using a cutting board base... it has a grip to hold! ARDUINO Duemilanove and full rotation servos from sparkfun.
Looks like a nice starter project.
Does it do some light seeking, hence the photocells?
I have made two scripts.. one to go to the ligth and other to avoid it. After some cut and paste from arduino.cc and others it works.. Like the Breitenberg book robots.. it is very interesting to the beginner.
