ArduBot is home made robot fully printed on the reprap 3D printer. It is based on arduino nano board, servos and ultrasonic sensor. It is easy to print, assemble, small, fun and great intro into electronics and robotics. ArduBot is fully controlled by IR remote control and it has 3 modes: Video: https://www.youtube.com/watch?v=4a9aTn8atQU If you want to build ArduBot, you can downolad souce code, schematic and also 3D designs at: https://github.com/davidhrbaty/ArduBotThe robot assembling is easy.
