Well, I never thought I would see the day but skiing robos will be here soon. If you ever programmed a robot, you can appreciate how complex the programming must have been.
I've already seen biking riding robos, but not mtb robos. However, if they can make one ski, robos on National trail can't be too far behind. The Japanese have them pitching and hitting baseballs.
anyway, found the story on my very own http://fat-tire.net/
