As soon as you start showing off your new robot to your friends, you can bet that one of their first comments will be something like, "Yeah, that's great, but what can it really do that's useful?" For some popular robots your only response might be something kind of lame like, "Well, it can belch!" or "It tells really dumb jokes and wolf whistles at pretty girls!" Fun stuff, but not likely to win the respect from your friends that you're looking for.
Tf2psycho wasn't satisfied with that type of response, so with a little imagination and creativity he was able to train his R2D2 robot to respond to his voice commands, and to do something really practical, as you can see from the video below.
Tf2psycho has also found some neat Easter Eggs hidden within the R2D2 robot that we'll be posting about soon.
