This thing is made with OOML (V2.0)

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:
