The accelerometers
1549's bot uses sort of hybrid skid steering. We have the regular wheelchair wheels on the front and some big solid rubber tires on the back. needless to say, our center of rotation is constantly changing, even in the middle of a turn.
My question is this: If i mounted two accelerometers on the bot, one 1/4 bot length from the front and another 1/4 bot length from the back how hard would it be to mathematically figure out how far i turned?
Also, do i even need to have two censors?
:edit for spelling:

Go with what you know will work, and try a little less if you are feeling brave. That is my rule of thumb. - sanddrag [more]
