Wow, this is pretty sweet. Oomlout, creaters of the OAWR and SERB robot projects, are using a Wii Nunchuck to control their SERB robot. Too bad it’s not wireless.
If you’re curious about Oomlout’s work, you can check out their website or their photostream on Flickr. From their website, you can find out how to make your own one of these bots, and purchase a kit for $175. Christmas present, maybe?
