meet Chief Knock-A-Homer
Here’s a nifty little line-following robot from Let’s Make Robots. The tech is pretty commonplace: two light sensors watch for a line of black tape and instruct two drive motors which way to turn. As is often the way with DIY electronics projects, the real creativity comes with the case design and finishing.
Modeled after a robot from an episode of the The Simpsons, the Chief Knock-A-Homer is CNC-cut and hand painted. The maker ‘psychofreaky’ goes into plenty of detail to explain his finishing techniques: valuable information for any aspiring DIYers.
