This 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. How To Use: Step 1 - Use the Drawbot marker to draw a line on a white piece of paper. Step 2 - Turn on the Drawbot. Step 3 - Place your Drawbot on top of the drawn line. Step 4 - The Drawbot will run on the line automatically. Step 5 - If the line finishes, Drawbot will continue in the direction followed from the previous line. Specifications This clever robot follows the lines you draw!
