NXT Club Dance Robot, 3it3ot (BitBot)
Master builder NeXTSTORM keeps amazing us with his robot creations, and here's yet another inspirational design. In the past, the NXT has been combined with music several times, but this approach is one I haven't seen yet. Just watch the video to see what I mean, and read more on NeXTSTORM's webpage.
He continues to produce amazing creations!
Guess you would do well in FLL or so if you went for it.
