Xavier Plantaz, Partner Solutions Engineer at Google, brings two Open Duck Mini v2 robots, built by Antoine Pirrone, on-device with Gemma 4. One runs Gemma 4 E2B on LiteRT on a Raspberry Pi 5. The other runs Gemma 4 E2B on a Jetson Orin Nano. Microphones, cameras, speakers, and Gemma’s multimodal inputs let each duck listen, look, and talk back in real time.
What’s covered: Running Gemma 4 E2B on Raspberry Pi 5 and Jetson Orin Nano, the on-device voice stack (Parakeet for speech-to-text, Gemma 4 for inference, Kokoro for text-to-speech), LED and antenna expressiveness, attention mode and live conversation, and where the project goes next as the ducks start to see and talk to each other.
Explore the Open Duck Mini v2 project on GitHub and try running Gemma 4 on your own hardware.
