Inspired by her interest in competitive rowing, Becky Lippmann built Row-Bot, whose realistic rowing motion enabled it to paddle around a turtle shaped pond. The Row-Bot started moving whenever it heard a "clap". (It used a "clap sensor" that was designed and built by Laura Wollstadt.)
The Row-Bot was powered and controlled by a "Cricket", a tiny computer not much bigger than a LEGO brick, which was developed in collaboration with the MIT Media Lab.
