# Feeling Machine
An expressive robot app that responds to users through **emotions only** - no speech output.
The robot listens to what you say and responds with expressive motion and procedurally-generated sounds based on the **PAD model** (Pleasure, Arousal, Dominance).
## Features
- **PAD-based emotion generation**: Motion and sound are generated procedurally from emotional parameters
- **Named emotions**: joy, happiness, anger, fear, sadness, surprise, boredom, uncertainty, disgust, neutral
- **Custom PAD values**: The LLM can specify precise P/A/D values for nuanced expressions
- **No speech**: The robot expresses itself only through body language and generated sounds
## PAD Model
The PAD model represents emotions in a 3D space:
- **P**leasure: Positive (+1) vs negative (-1) emotion
- **A**rousal: Excited/energetic (+1) vs calm/relaxed (-1)
- **D**ominance: In control (+1) vs submissive (-1)
## Usage
```bash
cd src/feeling_machine
python main.py --gradio
```
Then open http://127.0.0.1:7860/ or http://127.0.0.1:7861/
## Classic Emotions
If you specifically ask for "classic" emotions, the robot can play pre-recorded emotions from the Pollen library instead of PAD-generated ones.
