The outcome

AI-powered robotic desk lamp running on a Raspberry Pi: a 5-DOF articulated arm, an 8x8 LED matrix face with animated expressions, and real-time voice conversation over Deepgram STT, GPT-4o-mini, and Edge TTS.

The build

MediaPipe hand tracking, a FastAPI control dashboard, and Firestore audit logging tie the hardware to the assistant.
