Ultrasonic sensor movement Boe-bot

Marc_87

Hello all,

I have a question. I am programming a Boe-bot whit three Ultrasonic sensors on it.
The sensors are mounted on the front and on the left and right side.
The idea is that the Boe-bot must drive through a maze. The problem whit this is
that I cant get the Boe-bot drive straight ahead through the maze. The walls are
every where at the same distance from each other. So when the Boe-bot is going
to far to the right it must ajust so it goes straight again and that is what not is working
very good at the moment.

Hopefully someone on this forum will have a couple of hints to get that right for me.

Please provide more information. Where are the sensors mounted and where do they face? What's the size of the maze? What kind of readings do you get when your BoeBot is still, sitting in the maze?
