This kit uses QTI infrared emitter/receiver modules to easily enhance the line-following capability of your Boe-Bot robot. Mount three or four sensors underneath the Boe-Bot chasis, and adjust the position to detect lines of different widths. Learning to use the QTI is easy with the illustrated instructions and example BASIC Stamp code provided.
Features:
- Designed for close proximity infrared detection
- Use as a digital sensor array to detect black lines in order to follow electrical tape courses or navigate mazes
- Use as an analog sensor to detect shades of gray
- Challenge your friends by setting up Boe-Bot line following competitions!
