The Line Tracing Snail uses a special LED sensor to detect a black line (magic marker, etc.) drawn on a white background. It uses two small motors and rubber tires to slowly but surely move forward and turn. The body of the snail is made of transparent (HIPS) plastic to allow viewing of the intricate mechanisms inside. No soldering required! Check out Jameco's Electronic Adventure for building the Line Tracing Snail kit.
