Ruby is For Fun and Robots
summary
Builds a roaming social robot by gluing together an iRobot Create base, a Raspberry Pi, a cheap webcam and batteries, runs motion/state code in Elixir (serial at 115200 baud) and vision in Ruby via spyglass OpenCV, sends images to Google Cloud Vision and posts troll tweets. Sensors poll 30 times a second, vision runs ~10 fps on the Pi, roughly 90–100 hobby hours so far. Demos include unexpected boot and camera failures and a joyfully chaotic mid‑night “it ran away” moment.
