Robot Telemetry & Observability

I have defined the signals catalogue for your delivery robots and generated the corresponding Grafana dashboard configuration. The setup includes specific thresholds for battery health and localization quality.

Robotics Observability Configuration

1. Signals Catalogue

2. Grafana Dashboard JSON (Snippet)

{
  "panels": [
    {
      "title": "Fleet Mission Success Rate",
      "type": "stat",
      "datasource": "Prometheus",
      "targets": [
        {
          "expr": "sum(rate(robot_mission_status{status='success'}[5m])) / sum(rate(robot_mission_status[5m]))",
          "legendFormat": "Success Rate"
        }
      ],
      "fieldConfig": {
        "defaults": {
          "unit": "percentunit",
          "thresholds": {
            "steps": [
              {"value": null, "color": "red"},
              {"value": 0.95, "color": "green"}
            ]
          }
        }
      }
    },
    {
      "title": "Localization Quality by Robot ID",
      "type": "timeseries",
      "targets": [
        {
          "expr": "avg by (robot_id) (pose_covariance)",
          "legendFormat": "{{robot_id}}"
        }
      ]
    }
  ]
}

Next steps

1. Implement the diagnostic_updater in your ROS 2 nodes to publish these metrics to the /diagnostics topic.
2. Configure the mcap recorder to trigger a 30-second snapshot whenever mission_status equals Failed.
3. Import the provided JSON into your Grafana instance and link it to your Prometheus data source.
