Concept scenario
City Sewage Blockage Prediction and Early Warning
Scenario record: it defines the environment, the mission flow and a proposed hardware and software configuration. The list below is a configuration proposal, not an installation inventory. Field projects lists deployed systems and their measurements.
- Environment
- Outdoor field
- Operating mode
- Supervised autonomy
- Proposed robot
- Unitree A2
The problem addressed
Sewer blockages turning into floods and environmental disasters without detection.
Draft mission flow
- 1The robot descends into sewer manholes and scans inner walls of large diameter collectors with endoscopic camera.
- 2Detects blockage precursors such as grease buildup, root intrusion, collapse, and sand accumulation.
- 3Measures current fill rate and flow speed with ultrasonic flow sensor; blockage prediction algorithm executed.
- 4Blockage risk map transmitted to SCADA system; points requiring urgent cleaning before rain prioritized.
Proposed hardware
- IP68 Waterproof Body
- HD Endoscopic Camera
- Ultrasonic Flow Sensor
- H₂S/CH₄ Gas Detector
Proposed software
- Navigation
- Water-edge safe SLAM in sewer manholes and large diameter collectors
- Model
- In-Pipe Blockage/Collapse Detection, Flow Speed Anomaly and Fill Rate Prediction
- Integration
- Municipal Infrastructure Management System (SCADA) and Flood Early Warning Network

Values are manufacturer data. Scenario fit is determined by comparing these limits with site conditions.
From scenario to installation
Feasibility is determined by the site survey: floor and route, network coverage, the charging point, intervention responsibilities and the conditions under which the robot must stop. The survey report defines the scope, the constraints and the commissioning steps.
