“THERE GOES . . . WEASEL!” Weasel has two sensors that allow it to “see” a line or “feel” its way along walls and around corners. The two motors and contact sensor activate the wall sensing micro switch to control the motors’ on/off operation that determines the path of a wall. It is the classic robot design using the “Left Hand Rule” to escape mazes. Imagine the endless mazes that can be set up for Weasel to try to escape! With OWI’sTM continued pursuit in making robots “smart”, they have added another feature to this little bundle of energy . . . a sonic tracking system. Discover and learn about the phototransistors underneath Weasel that enable it to detect and follow a black line. Want speed? Its three-speed gearbox will help navigate at the velocity you determine. Unassembled circuit board kit requires soldering. This is a beginner robot that makes great entrants for robotic competitions, robotic workshops, afterschool programs, special events, gifts, science enrichment
