I would say "YES" since it is Arduino compatible. But that would sort of Cheapin it. But, to make sure, ask D.J.

The arduino compatible is Sheild compatible, not arduino software compatible. The answer is no for Arduino code.

If you wanted to overwrite the boot loader by programming the chip yourself, the programming pins are available - but you lose teh EZ-Robot connectivity and end up with an over-priced microcontroller board

The strength of EZ-Robot is in our communication protocol, graphic design environment, and firmware. Those together are what make EZ-Robot very powerful. If you reprogram the chip and lose that, you'll be sad

Very sad, the tracking alone is something incrediable to get programmed. Though I'm sure you can find code out there to reference from implementing and creating your own is something entirely different.
