Requirements:

• An Android or IOS device with the Cozmo App connected via USB to your PC or Mac;

• A GCP project with billing enabled for speech-text (you can stay in the free tier);
• A Picovoice key and a Porcupine keyword file for the "Hey, Cozmo" keyword detection;
• ADB (Android Platform Tools) if using an Android device.

Setting up and running:

• Run ./setup/install_packs.sh to install the required packages and create the virtual environment.
• Get a Gemini dev key: https://ai.google.dev/
• Get your Picovoice keys and keyword file here: https://picovoice.ai/
• Install gcloud CLI: https://cloud.google.com/sdk/docs/install
• Run gcloud init to set it up and follow the instructions.
• Run gcloud auth application-default login to get credentials.
• Edit the keys/env_keys.sh with your keys and Picovoice keyword file:

export PICOVOICE_KEYWORD_PATH=./keys/[enter your hey-cozmo*.ppn here]
export PICOVOICE_ACCESS_KEY=[enter your Picovoice key here]
export GOOGLE_API_KEY=[enter your google API key here]

• [If using an Android Device] Install ADB and edit /setup/set_env.sh to point the variable ADB_PATH to the platform-tools directory on the ADB installation path.
• Finally, run ./start_cozmini.sh and start interacting with Cozmini by voice or on the web browser UI at http://127.0.0.1:5000.

Limitations

• At some point, the user_data/conversation_history.txt file will become too large and won't fit into the Gemini context window. This will result in Error 500. Delete the contents of this file (or a portion of it) to fix the error. Cozmini will forget the things you deleted.

Disclaimer

• Note that text, audio, and images captured will be sent to Gemini, so look at their terms of service
