3 people. 3 languages. 1 robot dog that understands them all.
Speak French, Hindi, German, or English — the Unitree Go2 robot dog obeys every command and confirms in English.
Built at the Robotic Agents Hackathon (SF, March 2026).
[Voice FR/HI/DE/EN]
→ Smallest.ai Pulse STT (multilingual transcription)
→ Ollama gpt-oss:20b (translate + extract robot command as JSON)
→ Cyberwave SDK (Unitree Go2 robot dog moves)
→ Smallest.ai Waves TTS (English voice confirmation)

# 1. Install
chmod +x setup.sh && ./setup.sh
# 2. Set API keys
export SMALLEST_API_KEY="your-key"
# Ollama runs locally — ensure `ollama serve` is running with model gpt-oss:20b
export CYBERWAVE_API_KEY="your-key"
# 3. Run
python main.py # Full voice mode (mic required)
python main.py --test # Test mode (type commands)# Test LLM parsing only (no mic needed, only Ollama)
python test_speech_to_command.py --mock
# Batch test all languages (23 preset commands)
python test_speech_to_command.py --batch
# Test all robot commands in mock mode (no API keys needed)
python test_robot_commands.py
# Test LLM → Robot chain (type commands)
python test_robot_commands.py --llm
# Run the hackathon demo sequence
python test_robot_commands.py --sequence
# Test with real robot (sends actual commands)
