Miabot Classic Infra-red Line-following Kit

The Infra-red Line-following Kit can be attached to the expansion port on the front of the MIABOT Classic or Pro. 

The sensor kit delivers three digital signals to the micro-controller so the MIABOT can reliably follow a black line on a white background, or vice versa. This is a reliable, easily-set-up application that will perform effectively time and time again.

The kit has three reflective sensors made from one-peice infra-red LED and photo-detector pairs that are directed at the surface in front of the MIABOT.

Each of the sensors looks for reflected IR light. When one of the sensors is positioned over a dark or black surface its output will be low. When it is moved to a light or white surface its output will be high. The micro-controller monitors these signals and moves the MIABOT according to the signals.

The infra-red line-following kit works best with line thicknesses from 1/4" to 3/4". Lines that are made from electrical tape will suit most applications: the track can be black tape on a white background or white tape on a black background, as long as the surface has a matte (not shiny) finish.
