How to Build a Robot at Home — Quaddle Assembly & Feature Demo | Open Source Physical AI Kit

How do you build a robot at home, step by step? This is the complete walkthrough: assembling Quaddle from raw components, walking as the Builder tier, then upgrading into Buddy and Scout — Quaddle, Petoi's open-source, do-it-all desk robot, snaps together with just 4 screws, no soldering required, in under 20 minutes. You'll also see how to add a Raspberry Pi Zero as the brain, mount Petoi's AI vision module — it can track human bodies, faces, poses, and gestures, and classify up to 80 everyday objects, running off-the-shelf or your own custom AI models (MobileNet, EfficientNet-Lite, YOLOv5/v8) over TensorFlow or PyTorch — mount Quaddle on a 3D-printed test stand, swap between different battery options, and connect LEGO. All snap-on, interactive structures packed into a small, compact robotics kit. It's a real example of engineering and design coming together to build a dynamic robot you assemble, code, and upgrade yourself. Build, play, code your Quaddle.
