Here is my first working robot. It is very simple, but a good start.[youtube http://www.youtube.com/watch?v=6hKtEQSAFKA]
The electronics parts:
- 1 x Arduino Mega (but an Arduino Uno would have been more suitable)
- 1 x L293D chip
- 2 x Micro metal gear motor
The parts are mounted on a piece of plywood that I cut to size.
