Check Status

When to Use

Use this skill when the user asks about the robot's state:

• "How's the robot doing?"
• "What's the battery level?"
• "Check the sensors"
• "Is anything wrong?"

Steps

1. Battery: Use ros2_subscribe_once on /battery_state to read battery level and charging status.
2. Position: Use ros2_subscribe_once on /odom or /amcl_pose to get the robot's current position.
3. Diagnostics: Use ros2_subscribe_once on /diagnostics to check for warnings or errors.
4. Sensors: Check /scan for LIDAR status, /camera/image_raw for camera availability.

Example: Check battery

Tool: ros2_subscribe_once
Topic: /battery_state
Type: sensor_msgs/msg/BatteryState

Report the percentage, voltage, and whether the robot is charging.

Tips

• Summarize the status in a human-readable format.
• Highlight any warnings or abnormal values.
• If a sensor topic is unavailable, note it as "not reporting" rather than failing.
