I am C, I am a super fan of robot.
It is really excited when you finish assembly or solder one world-shaking robot.
Do you think so!!!
It is easy to use Arduino to programm your robot.
My farority robot is ASURO, which will bring you a lot of fun. I recommend to my friends, they all love it.
As you can search in goole " Arduino ASURO", you will see all the world is playing ASURO.
