I am gathering information to build my own balancing robot. With two wheels side by side like a Segway, not front to back like a bicycle.
This requires sensors to let the processor know how off ballance the robot is and to provide data for the processor to calculate how much and how fast to move the wheels.
Most site I've found use both an Accelorometer and a Gyroscope. The Accelorometer tells the robot where down is, that way it can ballance on an incline, and the gyroscope provides tilt information.
I have already received sample accelorometers from analog.com
I have single axis analog, dual axis analog, and dual axis digital...two of each.
Since Gyroscopes seem to be quite expensive for a small project like this, I was thinking about it and was wondering if it would be possible to just use two accelorometers to do the job. One could provide a reference for ground so then, would it be possible to have the other one provide tilt by subtracting the gravity reference from its own measurement?
Thanks!
