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.

The snail emits an infrared light from the Light Emitting Diode on the underside of its chassis. A photo transistor picks up the reflection of the infrared light to distinguish black from white surface. Transistor sensitivity can be adjusted to adapt for a variety of paper sizes and line widths.

Snail's eyes move in-synch with tires. Snail is capable of low/high-speed setting. Low-speed mode suitable for fine lines and narrow areas. High-speed works best for wide areas and thick lines. Snail follows the line without fail. Feel free to line up a family of snails for even more line tracing, robotic wackiness. Opaque body can be painted for added style.
