I’m currently working on a rover project with some young engineers and we’re trying to come up with ways to build an odometer. One of the ideas was to attached an alternating white/black disk to the (12cm diameter) wheel and use this colour sensor to check the segments as they whiz past. I know this won’t be nearly as accurate as a proper odometer, but if we were manage to measure 1/8ths of the circumference of the wheel would be a good start. Does anyone know if that sensor is up to the job?
Any other ideas are much appreciated, we’re currently also looking at hacking an old optical mouse.
