About this 3D model

This thing is made with OOML (V2.0) http://iearobotics.com/oomlwiki/doku.php I have kept the main structure and I have added a little of light to my prototype. In this way you can enjoy in the darkness solving a labyrinth, for example. I have used to do this derivative model: 1 x Arduino UNO 1 x Bluetooth Arduino Module 2 x Futaba 3003 2 x Ultrasonic Sensors (Link: http://www.seeedstudio.com/wiki/index.php?title=Ultra_Sonic_range_measurement_module) 1 x Protoboard 2 x 9V power batteries 2 x red LEDs 2 x yellow LEDs 2 x green LEDs 3 x resistors (220 ohms aprox.) In the next link, it is the first training video: http://youtu.be/-5mcAUBTQyI?hd=1
