Eva-Robot, Local AI Companion ESP32-S3

Hey! I'm a self-taught builder who loves creating devices that actually do something useful. This is Eva — my first robot companion project. I wanted to build something I could talk to, that could look around and describe what it sees, and that runs completely offline. No cloud, no subscriptions, just local AI on my PC. It was a test of my own abilities combining firmware, AI pipelines, voice cloning, and 3D printing into one working thing. The enclosure is simple and functional rather than polished, but everything works as intended. I'm sharing this because I'd love to hear your feedback, see your builds, and learn from your experience. If you run into any issues or have ideas to improve it open an issue on GitHub or drop a comment here. Maybe this gives someone a cool toy, or maybe a real companion. Either way, I hope it's useful.
