## What It Does

Agent ROS Bridge sits between your AI agent and your robots. It speaks WebSocket, MQTT, and gRPC on the agent side, and ROS1/ROS2 on the robot side — with JWT auth, agent memory, safety confirmation, and fleet orchestration built in.

## Quick Start (no ROS required)

The fastest path uses the built-in **simulated robot** — a full bridge with a virtual TurtleBot that responds to commands over WebSocket, with zero ROS installation needed.

### 1. Install

```bash
pip install agent-ros-bridge
```

### 2. Set JWT secret

```bash
export JWT_SECRET=$(openssl rand -base64 32)
```

> The bridge will refuse to start without `JWT_SECRET`. This is intentional.

### 3. Start the simulated bridge

```bash
python examples/quickstart/simulated_robot.py
# WebSocket available at ws://localhost:8766
```

Or with Docker:

```bash
docker-compose -f examples/quickstart/docker-compose.yml up
```

### 4. Generate a token and connect

```bash
# Generate a JWT token
python scripts/generate_token.py --user myagent --roles operator

# Connect with wscat (npm install -g wscat)
wscat -c "ws://localhost:8766?token=<TOKEN>"
```

### 5. Send commands

```json
{"command": {"action": "list_robots"}}
{"command": {"action": "get_topics"}}
{"command": {"action": "move", "parameters": {"direction": "forward", "distance": 1.0}}}
{"command": {"action": "rotate", "parameters": {"angle": 90}}}
```

---

## Python API

### Basic bridge

```python
import asyncio, os
from agent_ros_bridge import Bridge
from agent_ros_bridge.gateway_v2.transports.websocket import WebSocketTransport

os.environ["JWT_SECRET"] = "your-secret"   # or set in env before importing

async def main():
    bridge = Bridge()
    bridge.transport_manager.register(WebSocketTransport({"port": 8765}))
    async with bridge.run():
        print("Bridge running on ws://localhost:8765")
        while bridge.running:
            await asyncio.sleep(1)

asyncio.run(main())
```

### With LangChain

```python
from agent_ros_bridge import Bridge

bridge = Bridge()

# Get a LangChain-compatible tool
tool = bridge.get_langchain_tool(actions=["navigate", "move_arm", "get_status"])

# Plug into any LangChain agent
from langchain_core.tools import BaseTool
from langchain.agents import AgentExecutor, create_react_agent

agent = create_react_agent(llm, [tool], prompt)
executor = AgentExecutor(agent=agent, tools=[tool])
result = executor.invoke({"input": "Navigate the robot to zone A"})
```

### With Claude Desktop (MCP)

```python
from agent_ros_bridge import Bridge

bridge = Bridge()
mcp = bridge.get_mcp_server(mode="stdio")
await mcp.start()   # Claude Desktop can now control robots
```

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "agent-ros-bridge": {
      "command": "python",
      "args": ["-m", "agent_ros_bridge.integrations.mcp_transport"],
      "env": {
        "JWT_SECRET": "your-secret-here"
      }
    }
  }
}
```

### With AutoGPT

```python
from agent_ros_bridge import Bridge

bridge = Bridge()
adapter = bridge.get_autogpt_adapter()

# List available commands
commands = adapter.get_commands()

# Execute a command
result = await adapter.execute_command("ros_navigate", target="zone_a")
```

### With OpenClaw

```python
from agent_ros_bridge import Bridge

bridge = Bridge()
adapter = bridge.get_openclaw_adapter()

# Get ClawHub skill path
skill_path = adapter.get_skill_path()
print(f"Skill location: {skill_path}")
# Package for ClawHub: cd {skill_path} && python scripts/package_skill.py

# Or use extension mode
tools = adapter.get_tools()
result = await adapter.execute_tool("ros2_publish", {
    "topic": "/cmd_vel",
    "message": {"linear": {"x": 0.5}}
})
```

**Install via ClawHub:**
```bash
# When published to ClawHub
npx clawhub@latest install agent-ros-bridge

# Or manually package and install
cd skills/agent-ros-bridge
python scripts/package_skill.py
# Upload dist/agent-ros-bridge.skill to ClawHub
```

**Natural language commands (via OpenClaw):**
- `"Move forward 1 meter"` → publishes to `/cmd_vel`
- `"Navigate to the kitchen"` → sends Nav2 goal
- `"What do you see?"` → captures camera frame
- `"Check the battery"` → reads `/battery_state`
- `"Emergency stop"` → triggers safety e-stop

### Agent memory

```python
bridge = Bridge(config={"memory_backend": "sqlite", "memory_path": "/tmp/bridge.db"})

# Memory is automatically attached to Bridge.memory
await bridge.memory.set("last_position", {"x": 3.0, "y": 1.5}, ttl=3600)
pos = await bridge.memory.get("last_position")

# Append to a history log
await bridge.memory.append("agent:user1:actions", {"action": "navigate", "ts": "..."})
```

### Safety confirmation

```python
from agent_ros_bridge.integrations.safety import SafetyManager, SafetyLevel

safety = SafetyManager()
safety.register_policy("move_arm", SafetyLevel.DANGEROUS, "Arm movement requires confirmation")

# Register a callback to receive confirmation requests (e.g. send to operator dashboard)
def on_confirm_request(request):
    print(f"Operator approval needed: {request.id} — {request.message}")

safety.on_confirmation_request(on_confirm_request)

# Approve via request ID
await safety.confirm(request_id)

# Emergency stop
safety.trigger_emergency_stop("Obstacle detected")
```

### Fleet orchestration

```python
from agent_ros_bridge.fleet import FleetOrchestrator, FleetRobot, RobotCapability, Task

orchestrator = FleetOrchestrator()
await orchestrator.start()

# Register robots
await orchestrator.add_robot(FleetRobot(
    robot_id="tb4_01", name="TurtleBot4 #1",
    capabilities=RobotCapability(can_navigate=True, battery_hours=4.0)
))

# Submit tasks
task_id = await orchestrator.submit_task(Task(
    type="navigate", target_location="zone_b", priority=3
))

metrics = orchestrator.get_metrics()
print(f"Fleet: {metrics.idle_robots} idle, {metrics.active_robots} active")
```

---

## Docker

### Development / CI (no ROS)

```bash
# Build
docker build -t agent-ros-bridge .

# Run with JWT secret
docker run --rm -e JWT_SECRET=$JWT_SECRET -p 8765:8765 agent-ros-bridge
```

### With ROS2 Jazzy

```bash
docker build -f docker/Dockerfile.ros2 -t agent-ros-bridge:ros2 .
docker run --rm \
  -e JWT_SECRET=$JWT_SECRET \
  -e ROS_DOMAIN_ID=0 \
  -p 8765:8765 \
  agent-ros-bridge:ros2
```

### docker-compose (profile-based)

```bash
# ROS2 bridge only
JWT_SECRET=$JWT_SECRET docker-compose --profile ros2 up

# ROS1 bridge + roscore
JWT_SECRET=$JWT_SECRET docker-compose --profile ros1 up

# ROS2 with TurtleBot4 simulator
JWT_SECRET=$JWT_SECRET docker-compose --profile ros2 --profile sim up
```

## Connecting to a Real Robot (ROS2)

> ROS2 publish/subscribe implementation is in progress. The following shows the intended workflow:

```bash
# 1. Install with ROS2 support
pip install "agent-ros-bridge[ros2]"

# 2. Source your ROS2 environment
source /opt/ros/jazzy/setup.bash   # or humble

# 3. Set config pointing at your ROS domain
cat > config/gateway.yaml << EOF
name: my_robot_bridge
transports:
  websocket:
    port: 8765
    auth:
      enabled: true
      jwt_secret: ${JWT_SECRET}
connectors:
  ros2:
    enabled: true
    options:
      domain_id: 0
EOF

# 4. Start
agent-ros-bridge --config config/gateway.yaml
```

---

## CLI Reference

```bash
# Start with default config (WebSocket on 8765, gRPC on 50051)
agent-ros-bridge

## Security

- `JWT_SECRET` is always required — the bridge refuses to start without it.
- Authentication is opt-in per transport via config (`auth.enabled: true`). The simulated quickstart runs without auth for ease of development.
- RBAC roles: `admin` (all), `operator` (navigate/publish/subscribe), `viewer` (read-only).
- TLS: pass `tls_cert` / `tls_key` in transport config.
- Generate tokens: `python scripts/generate_token.py --user robot_agent --roles operator`

---

## Development

```bash
# Install dev + test dependencies
pip install -e ".[dev,test]"

# Run all tests
pytest

# Run specific suites
pytest tests/unit/ -v
pytest tests/integrations/ -v        # SafetyManager, Memory (no ROS needed)
pytest tests/integration/ -v         # requires running bridge

# Lint + format
ruff check .
black --check .

# Build package
python -m build
```
