Product Description

The QTI Line Follower AppKit uses an array of QTI infrared emitter/receiver modules to easily enhance the line-following capability of your Boe-BotActivityBot 360°Arduino based Shield-Bot, or micro:bit based cyber:bot robot. Mount three or four sensors underneath the chassis, and adjust the position to detect lines of different widths. Learning to use the QTI is easy with the illustrated instructions and example code for BlocklyProp, Propeller C, BASIC Stamp, Arduino, or micro:python. Just browse the Downloads tab below. This kit includes all the circuit and sensor hardware you need to add QTIs to your Parallax small robot.

Key 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 a robot line following competitions!

Note: You will need to supply your own robot, white poster board, and black electrical tape.
