The PrintBot Beetle is an educational robot that can follow lines, search for light, and grab objects with its claw.
You can see it in action at http://youtu.be/cYbD-ICMmU8
The robot has been designed to attach other components such as servos, LEDs, push buttons, a buzzer, and other sensors included in the product "Zum Box" distributed by BQ.
You will need to print one copy of each part, except for the following:
4 x screw_cover
2 x wheel_front
2 x wheel_rear
7 x M3x10 screw
1 x M3x12 screw
8 x M3x16 screw
2 x M3x25 screw
2 x M3x35 screw
14 x M3 nut
3 x M3 blocking nut
4 x 3x84mm O-ring
8 x AAA batteries
Parts included in "Zum Box" by BQ:
1 x Battery holder
1 x BQ Zum Core
2 x IR sensor

See the attached pdf (in Spanish) in the "Files" section. Pictures are clear enough to follow the steps even if you do not understand Spanish.
Attached you will find two simple Arduino programs ("Arduino_escarabajo..."). One follows a line and the other searches for the brightest spot.
Now you can control your robot through the "RoboPad" app.
So just upload the "Arduino_robopad_escarabajo.ino" into your robot, connect the Bluetooth Module and install the Android app:
