Dance.Bot is currently on Display in the window of a bank in Harvard Sq. in Boston, spreading the word about dance month.

Watch a small Quicktime movie [316kB].

Following up on my now-broken CD.Bot, I created a Dance.Bot to rock to the rhythm. This little yellow guy is similar in construction to his larger cousin, but as his name indicates, he dances. Right now he's fairly simple, just moving along at his own beat. Soon he'll have a distance sensor to start dancing when someone moves up to him LEDs to light his internals, and hopefully beat tracking to dance in rhythm!

Take a look at the photos to see inside - it all runs off of one LEGO motor, gearing out to the two arms and the head. There is a light sensor on each shoulder, pointing up, to detect when his head is aligned with his body (I put black electrical tape on the bottom of his head to help account for varying ambient light conditions). The computational control is hiding in his leg. His body is made of bright yellow 3/8" acrylic (designed with my BoxMaker software).

You get the idea... just another bot to decorate the house with.
