# Vixy Eye Service 🦊👁️
|
|
|
|
Eye display control for head-lyra (Vixy's robotic head).
|
|
|
|
## Hardware

|
## Features
|
|
- **Direction of Arrival (DoA)**: Eyes follow sound sources
|
|
- **State-based animation**: Different colors/pulses per state
|
|
- **HTTP API**: Remote control via MCP or direct calls
|
|
- **Random flicks**: Realistic eye movement every 15-30 seconds
|
|
|

## API Endpoints
|
|
```
|
|
GET /health - Service health check
|
|
GET /state - Current eye state
|
|
POST /state - Set state: {"state": "listening"}
|
|
```
|
|
|
|
## Installation
|
|
```bash
|
|
# On head-lyra:
|
|
cd /home/alex/eyes
|
|
git clone http://gateway.local:3001/vixy/head-eyes.git .
|
|
sudo cp vixy-eyes.service /etc/systemd/system/
|
|
sudo systemctl daemon-reload
|
|
sudo systemctl enable vixy-eyes
|
|
sudo systemctl start vixy-eyes
|
|
```
|
|
|
|
## Usage
|
|
```bash
|
|
# Check state
|
|
curl http://head-lyra.local:8780/state
|
|
|
|
# Set state
|
|
curl -X POST http://head-lyra.local:8780/state \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"state": "listening"}'

```
|
|
|
|
## MCP Integration
|
|
Use `vixy_eyes_state` tool in vixy-mcp to control:
|
|
```python
|
|
vixy_eyes_state("listening") # Set state
|
|
vixy_eyes_state() # Get current state
|
|
```
