The Weasel is a tenacious little robot with photosensors that enable it to follow a black line on the floor, and a contact sensor for feeling its way along walls and around corners. For this it uses the classic robot "Left Hand Rule" to escape mazes. And its three-speed gearbox will help navigate at the velocity you determine. Quick and easy to assemble, this is a beginner robot that is lots of fun but also makes great entrant for robotic competitions, robotic workshops, after-school programs, and special events. Weasel has been selected by the Children's Institute For Childhood Resources as one of the "100 Best Children's Products" and "10 Best Software/High Tech Products" for 2003.
