YASBR – Yet Another Self-Balancing Robot

The self-balancing robot building is today an activity that every robot builder can perform with Arduino. Searching in Google for self-balancing robot you can find tons of realizations, with tons of different sensors and control systems. So to build a self balancing robot is a standard task for the robot builder, like a simple home rover.

Trying to be at least original, I though to build a self balancing robot with these goals:

• low-low-cost
• simple in the hardware
• simple in the software 

So I tried to build a self-balancing robot using only one sensor: a Sharp IR distance sensor e nothing else. No gyro, no accelerometer, no other sensors. All is self-built, in the DIY pure spirit.

These are the components used:

• Plexiglass chassis
• Wheels for servo (Boe-Bot wheels). At first time I tryied to use two trolley wheels, but without success
• Servos modified
• Sharp IR sensor 10-80 cm
• Arduino 2009
• 2 batteries pack 4x1,2V 
• some screws, jumpers etc.

 We are under 100 euros, a good results concerning the cost.
