Drawbot

IWOOT - Stuff you really, really wantThis clever robot has an optical sensor that can detect drawn lines, allowing the robot to stick to that line better than polite people in a post office. It works best if you make the line super-thick and avoid hard turns. If you make a loop, the Drawbot will carry on following the line. And, if it reaches the end of a line, it’ll just keep going in in that direction. This robot is powered by 4 x button batteries, which are included. Also included is a marker, plus paper to draw on and an instruction manual.
