A small robot car has been built to detect a face with its camera, turn until that face is centered and then drive toward the person it sees. The project upgrades an Elegoo robot car kit with an Arduino UNO Q and webcam, using computer vision to locate faces and adjust steering. It was created by Iulia Feroli and featured on Arduino's official blog.

Face detection is familiar on a screen; connecting the detection result directly to motion gives the same software a much stronger physical presence.
