## 1. LiveKit Meet (Browser)

Quickest way to test.

1. Generate an operator token:
   ```bash
   ./scripts/generate_token.py \
     --api-key YOUR_API_KEY \
     --api-secret YOUR_SECRET \
     --room robot-room \
     --identity operator-001 \
     --role operator
   ```

2. Go to [meet.livekit.io](https://meet.livekit.io)

3. Enter:
   - URL: `wss://your-livekit-server.com`
   - Token: (paste the token)

4. Click Connect

## 2. LiveKit CLI

For debugging or headless testing.

```bash
livekit-cli join-room \
  --url wss://your-livekit-server.com \
  --api-key YOUR_API_KEY \
  --api-secret YOUR_SECRET \
  --room robot-room \
  --identity viewer
```

## 3. Custom Web App

Use the LiveKit JavaScript SDK.

```javascript
import { Room } from 'livekit-client';

const room = new Room();
await room.connect('wss://your-livekit-server.com', token);

room.on('trackSubscribed', (track, publication, participant) => {
  if (track.kind === 'video') {
    const element = track.attach();
    document.getElementById('video-container').appendChild(element);
  }
});
```

Install:
```bash
npm install livekit-client
```

## Token Roles

| Role | Can Publish | Can Subscribe | Use Case |
|------|-------------|---------------|----------|
| `robot` | Yes | Yes | asimov-manager |
| `operator` | Audio only | Yes | Viewing + teleop |

Generate tokens with `scripts/generate_token.py`:

```bash
# Robot token (long-lived)
./scripts/generate_token.py --role robot --ttl 8760

# Operator token (short-lived)
./scripts/generate_token.py --role operator --ttl 24
```
