This ingenious robot uses an optical sensor to detect and follow drawn lines with impressive precision�better than the most patient queue-goer at a post office! For optimal performance, draw a thick line without sharp turns. If you create a loop, the Drawbot will continuously follow it, and when it reaches the end of a line, it simply continues moving in the same direction.
Powered by 4 button batteries (included), the kit also provides a marker, drawing paper, and an instruction manual to get started right away.
