Description
ROS Noetic navigation system using Cartographer for localization, interfacing via TF and rosbridge to control move_base for waypoint navigation.
Usage Guidance
This skill appears coherent with its stated purpose, but a few practical cautions before installing or running it: 1) Verify the rosbridge endpoint you connect to — by default it uses localhost:9090; pointing it to an untrusted remote host could allow that host to influence your robot (publish goals, read status). 2) Inspect the included nav.py completely (the listing was truncated) before running to ensure there are no unexpected behaviors. 3) The scripts will read/write waypoints.json inside the skill workspace and the test script sources your local ROS workspace (~/robot5); ensure paths are correct and you trust those files. 4) Run this on a network-isolated development robot or simulator initially, and ensure your robot's safety mechanisms (e-stop, supervised operation) are enabled during testing.
Capability Analysis
Type: OpenClaw Skill
Name: ros-noetic-nav-cartographer
Version: 1.0.0
The skill bundle is a legitimate set of tools for ROS Noetic navigation using Cartographer. It includes scripts for managing waypoints (waypoints_manager.py), retrieving robot pose via TF (get_pose_tf.py), and executing navigation goals via rosbridge (nav.py). The code follows standard ROS practices for interacting with move_base and TF trees, and no evidence of malicious intent, data exfiltration, or prompt injection was found.
Capability Assessment
Purpose & Capability
The name/description (ROS Noetic + Cartographer navigation) matches the provided scripts and SKILL.md: get_pose_tf.py reads TF, waypoints_manager.py manages waypoints on disk, and nav.py publishes goals and subscribes to /move_base status via a socket to rosbridge. No unrelated credentials, cloud APIs, or unrelated binaries are requested.
Instruction Scope
SKILL.md confines runtime actions to ROS-related activities: starting rosbridge_server and Cartographer, sourcing ROS workspaces, reading/writing a local waypoints.json, querying TF, and sending/receiving messages to rosbridge. It does not instruct reading arbitrary system files, contacting external web services, or exfiltrating secrets. The only network interaction is to the rosbridge host/port the user supplies (default localhost:9090), which is expected for this purpose.
Install Mechanism
No install spec is present (instruction-only). The skill includes runnable Python scripts but does not download or install external code itself. This is low risk from an install mechanism perspective.
Credentials
The skill requests no environment variables, no credentials, and no config paths beyond guidance to add entries to a TOOLS.md and to reference local ROS workspace paths. The scripts read/write a local waypoints.json inside the skill workspace — proportionate for waypoint management.
Persistence & Privilege
always:false and no requests to modify other skills or global agent settings. The skill stores waypoints in its own waypoints.json in the skill directory, which is expected. Autonomous invocation is allowed by platform default but is not combined with broad privileges here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install ros-noetic-nav-cartographer - After installation, invoke the skill by name or use
/ros-noetic-nav-cartographer - Provide required inputs per the skill's parameter spec and get structured output
Version History
