$99 CMU robot is computer science learning tool

I remember programming turtle graphics in Logo when I was in high school. These days, students can learn basic computer science from a robot developed by researchers at Carnegie Mellon. The Finch was co-developed by Tom Lauwers at CMU's Create lab. It's designed to be an interactive, programmable teaching aid to get students into computer science and robotics. Programmable with Java and Python, the bird-like bot runs on a 15-foot USB cable and comes with temperature and light sensors, a bump sensor, and a three-axis accelerometer that can be used as a mouse.
