@CubieChansArt_twitter , Hi I assume you mean you want to record your robots position as it moves along. If you where looking at distances in tens of metre's you could use GPS. However, I guess you are looking at shorter distances, you could use a compass module to get direction and an encoder on a wheel to get distance. A wheel encoder could be as simple as a reed switch or Hall effect device fixed to the robot body and then a small magnet or magnets fixed to the wheel. One magnet would give a distance resolution of one wheel circumference. It all depends on what accuracy you are after. Signals from the sensors could then be wirelessly transmitted to a receiver unit for processing.
