Concept scenario
Escalator & Elevator Fault Early Warning System
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
- Indoor, public area
- Operating mode
- Supervised autonomy
- Proposed robot
- Unitree AS2
The problem addressed
Escalator and elevator breakdowns stranding customers and creating safety risks.
Draft mission flow
- 1Robot visits each escalator and elevator 3 times daily; performs mechanical health scan with vibration sensor and acoustic microphone.
- 2Thermal camera detects overheating in motors and gearboxes; anomalies outside normal profiles are reported.
- 3Worn step surfaces, broken handrails, and objects posing entrapment risk identified by camera.
- 4Maintenance priority queue created for high-risk equipment; automatic stop command sent in emergencies.
Proposed hardware
- Vibration Sensor
- Thermal Camera
- Acoustic Emission Microphone
- HD Camera
- 2D LiDAR
Proposed software
- Navigation
- Multi-floor patrol navigation using elevators between mall floors
- Model
- Mechanical Anomaly Detection (Vibration FFT Analysis), Thermal Hotspot Classification, and Sound Signature Matching
- Integration
- Mall Maintenance & Repair Work Order System (CMMS) and Elevator/Escalator Manufacturer API

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.
