Balancing bot

[soundman]

Hi There,

Just have a question.

Is this possible to make a balancing 2 wheels robot by common DC brushed motors (not use servos)? And just use a pair of IR transmitters and receivers and a micro controller? Not use any accelerator meter or gyro?

Thanks

Yes it is possible, but the IR sensors must be rangefinders, not just proximity detectors.

Thanks sir,

Any link in the field please?

Don't have any. My understanding is it's easy to program than a gyro/accelerometer balancing bot. You kind of treat it like an obstacle avoidance robot that tries to keep a certain distance from the wall, except you use forward and backward when the wall (or in this case, the ground) gets too close and you have to adjust the reaction times so it is stable.

Just google around.

You are lucky, yesterday somebody started a thread over on the Arduino forum about exactly the same type of project. He done some code:
