Printable tracks for letter-sized paper, designed to tape together for line-following. Useful with the Scribbler S3 Robot and QTI Line Follower AppKit for Parallax small robots. Designed for infrared line following systems, so print with inkjet or laser printer. Caution: black inks that contain graphite, such as those sometimes used in photo printers, may not work as graphite reflects infrared.
