Overview

Privacy-first embodied companion: Pi 5 + AI Camera for face/emotion, local Llama 3.2, Piper voice, and an ESP32 driving 2-DOF head tracking plus sound-reactive hands, with GC9A01 eye displays. Hackster project with contest wins.

How it works

A Pi 5 with the AI Camera recognizes faces and emotions, local Llama 3.2 and Piper handle conversation, and a single ESP32 drives the 2-DOF head turret and sound-reactive hands from tracking data sent over serial.
