Overview

This project is a GUI-based ROS 2 debugging and monitoring application built to simplify the inspection and analysis of complex robotic systems. It consolidates commonly used ROS 2 debugging workflows into a single, intuitive desktop interface—reducing reliance on multiple CLI tools like ros2 topic list or ros2 node list.

Key Features

Topic Monitor

Displays a live list of all active ROS 2 topics with message types, publisher/subscriber counts, and frequency. Supports quick inspection through a built-in echo tool and context-based copy actions.

Topic Monitor UI

Nodes & Graph View

Visualizes the complete ROS 2 computation graph. Provides a structured tree view of publishers, subscribers, services, and topic connections for each node, with filtering support.

Node Graph Visualization

TF Tree Visualizer

Automatically generates the TF (Transform) tree, exports it as a PDF, and renders it inside the application. Includes a static TF publisher utility and auto-refresh for dynamic frame updates.

TF Tree View

Performance & Power

Monitors real-time CPU, RAM, Disk I/O, and Network usage. Provides per-node ROS resource consumption and estimates system power usage. Includes a searchable ROS and system log viewer.

Performance Monitoring

Utilities (Bag & Services)

Integrated tools for recording and playing ROS bag files (.mcap / .db3), speed-controlled playback, and a GUI-based service caller supporting JSON and YAML requests.
