Settings: ROS Topics Explorer

Overview

The ROS Topics Explorer is a specialized diagnostic bridge that allows technical users and developers to "look under the hood" of the robot's real-time communication. It provides a live view of the messages being passed between the robot's sensors, solvers, and control systems.

Key Features

• Live Topic Discovery: Automatically lists every active communication channel (Topic) occurring on the robot's ROS 2 stack.
• Real-time Message Inspector: Select any topic to see the raw data—like Lidar distances, motor voltages, or path coordinates—in a human-readable format.
• Frequency Analysis: Monitor the "Hertz" (update rate) of each topic to identify lagging sensors or network strain.
• Message Type Browser: View the technical structure (Schema) of each message to understand exactly what data is being transmitted.
• On-the-Fly Debugging: Perfect for identifying why a sensor might be failing or verifying that a custom command was successfully received.

User Workflow

1. Topic Scan: A developer opens the explorer to see the entire list of 50+ active communication topics.
2. Detailed Inspection: They select /battery_state to see the individual cell voltages and temperature readings not visible on the main dashboard.
3. Connectivity Check: They verify that /scan (Lidar) is updating at a steady 10Hz to ensure the sensor is healthy.
4. Data Verification: After saving a new waypoint, they check the /waypoint_markers topic to confirm the data was published correctly.
