Paste this into Claude Code (VS Code panel, Adom editor, or terminal) to install:

Search the Adom Wiki for the molecule "Line Follower" (slug: line-follower-113280) at https://wiki-ufypy5dpx93o.adom.cloud/wiki/molecules/line-follower-113280. Download its symbol (.kicad_sym), footprint (.kicad_mod), and 3D model (.glb/.step) assets into my current KiCad project under symbols/, footprints/, and 3dmodels/ directories. Register them in the project library tables. Show me the files once installed.

Based on the QRE1113 miniature infrared reflectance sensor from onsemi, this line follower array is capable of detecting nearby changes in reflectivity. The sensor array operates at 3.3V and includes two analog signal outputs at 3.3V swing. This array directly interfaces with the XRP robot.

NSF Relevance

This molecule provides a hands-on line-following sensor array for the XRP robot, allowing students to experiment with real-time navigation, sensor response, and control algorithms as if the robot were physically in front of them. It enables interactive testing of autonomous behaviors and rapid iteration on robot programming in an experiential learning environment.
