Building An Arduino Obstacle Avoidance Robot
by Eileen Amirault (with a little help from Cody Gregory)

Last March Break, I read a book that changed my life. I immediately ran out and purchased an Arduino. A Raspberry Pi was not far behind. After a few months of experimenting, and watching YouTube videos of kids building Obstacle Avoidance Robots (OAR), we thought it looked like a good first project. We call it Bobby OAR. An OAR is an autonomous robot that rolls around and avoids obstacles by using sensor input. Then, based on programming, finds an alternate path forward, avoiding obstacles along the way. We had most of the components from various kits, so only a chassis and wheels needed to be ordered. Or was there something else?



You can make a strong, stiff case for your Raspberry Pi or other small computer using Coroplast, a plastic replacement for corrugated cardboard. A cheap retractable utility knife cuts Coroplast to shape, and scores it to make bends. Holes for mounting screws are easily punched through with a point. See the
