Radar Collision Warning

雷达防撞预警 — 调用树莓派上 ROS2 节点的雷达预警服务。当用户说"雷达防撞预警"、"开启雷达监控"、"检查障碍物"等时使用。通过 rosbridge WebSocket 向树莓派发送 ROS2 Service 请求，获取最近障碍物距离并给出预警。依赖 Node.js 18+（内置 WebSocket，无需安...

This skill appears coherent with its stated goal, but review the following before installing: - Network exposure: the skill uses rosbridge over an unsecured ws:// connection (default port 8080). By default rosbridge accepts unauthenticated requests on the network. Only run this with the Raspberry Pi on a trusted LAN or protect rosbridge (firewall, VPN, or authentication) to avoid unauthorized access. - Physical-safety risk: the ROS node publishes (commented-out) flight control commands and exposes a service that could be extended to issue control messages. Before deploying on any robot or vehicle, inspect and test the code in a safe environment and ensure control topics are appropriately restricted. - Local deployment: you must install and run the Python ROS2 node and rosbridge on the Pi (the SKILL.md explains how). The Node.js client runs locally and only connects to the Pi IP you supply (RADAR_HOST / RADAR_PORT). Confirm you control that Pi and network. - Minor code issues: there are small non-security bugs (e.g., a -d test where -f was intended in the start script) and the service uses response.success to indicate a collision state (true == danger), which is a semantic choice to be aware of. If you understand and accept the network and physical-safety implications, the skill is coherent and implementable. If you plan to expose the Pi to broader networks, add authentication and firewalling for rosbridge first.

Type: OpenClaw Skill Name: radar-collision-warning Version: 1.0.0 The skill bundle provides a legitimate interface for monitoring radar collision warnings via a ROS2 rosbridge WebSocket connection. The code (call_radar_service.js and radar_collision_warning_node.py) is well-documented, uses standard ROS2 patterns, and lacks any indicators of data exfiltration, obfuscation, or malicious execution. It correctly leverages Node.js 18+ built-in WebSocket capabilities to avoid external dependencies.
