Re: Filtering out Vibration while using a KOP Accelerometer

I've done a lot of navigation systems for FIRST robots. I would highly recommend NOT using accelerometers for determinings distances. Double integrations are thrown off easily by small offset shifts (which are inevitable). We always used a non-driven wheel with an encoder located as close to the center of the robot as possible. We always had good results with that.
