Robot Service

This skill documents the canonical external control surface for OpenClaw robots.

Architecture

Layer 1: robot_bridge on each robot

Default robot-side HTTP server:

• host: 0.0.0.0
• port: 8000

Supported mappings:

1. Navigation signal

• POST /api/navigation/{name}
• ROS topic: chat_signal_pub

1. Relative navigation

• POST /api/relative_nav
• ROS topic: /relative_nav
• JSON body: {"cmd": "forward,left,degrees"}

1. Semantic navigation

• POST /api/semantic_nav
• ROS topic: /chat_loc_pub
• JSON body: {"cmd": "floor,room,object"}

1. Arm skill

• POST /api/arm/{skill}
• ROS topic: arm_signal_pub

1. Stop navigation

• POST /api/navigation/stop
• ROS topic: chat_signal_pub

Health check:

• GET /health

Layer 2: multi_robot_ctl on the master machine

Default control-center port:

• 8080

Supported fan-out endpoints:

• POST /trigger/one_point_1
• POST /trigger/one_point_2
• POST /trigger/one_point_3
• POST /trigger/one_point_4
• POST /trigger/multi_point_1
• POST /trigger/multi_point_2
• POST /trigger/stop

Optional query parameter:

• robot_id=<id>
• robot_id=all

Workflow

1. Identify whether the request should go to a single robot bridge or the multi-robot control layer.
2. Confirm the target endpoint, robot scope, and payload format before sending the request.
3. Prefer documented HTTP endpoints and only fall back to ROS topics when appropriate for the integration.
4. Execute one service request at a time and inspect the returned status.
5. Report the endpoint, payload, and result clearly for downstream workflow tracking.

Safety Rules

• If the target robot is ambiguous, ask which robot should execute.
• If the command is unsafe or unclear, do not trigger the service.
• If unsure, stop and clarify.
