Concept scenario
Conveyor Belt Bearing Pre-Failure Acoustic Monitoring
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.

- Proposed robot
- Unitree A2
The problem addressed
Conveyor bearing failure causing unplanned line downtime and disrupting the shift plan.
Draft mission flow
- 1The robot stops at each bearing point along the conveyor line, collecting 5-second acoustic and vibration data.
- 2Edge AI detects early wear by comparing bearing degradation frequency signatures (BPFO, BPFI, BSF) against baseline.
- 3The bearing temperature profile is cross-checked with the thermal camera, and acoustic plus thermal data together produce a failure-probability score.
- 4Automatic work order opened in CMMS for detected degrading bearings; spare parts order transmitted to ERP.
Proposed hardware
- High Frequency Acoustic Sensor (10-100 kHz)
- Vibration Accelerometer
- Thermal Camera
- NVIDIA Jetson Orin NX
Proposed software
- Navigation
- Autonomous patrol along conveyor line with stops at bearing points (stop-and-listen)
- Model
- Bearing Degradation Frequency Signature Classification (BPFO/BPFI/BSF Anomaly Detection)
- Integration
- CMMS (Maintenance Management System) and Vibration Analysis Portal

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.
