Autonomous Nighttime Stock Counting (RFID/QR Scanning)
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.

- Unitree A2
The problem addressed
Halting production for the annual manual count (inventory freeze), plus the stock deviation manual counting introduces.
Draft mission flow
- 1The robot autonomously roams between shelves in warehouse corridors after hours; scans all inventory tags across all shelf levels with UHF RFID antenna.
- 2Expected stock from WMS database is compared with actual count at each scan phase; locations with deviations are instantly flagged.
- 3Products with damaged or missing RFID tags are cross-checked with visual verification via QR/barcode camera.
- 4Complete inventory report collected overnight is transmitted to WMS and ERP system before morning shift starts; automatic reorder suggestions generated.
Proposed hardware
- UHF RFID Reader Antenna
- QR/Barcode Scanner Camera
- 2D LiDAR
- LED Lighting Kit
Proposed software
- Navigation
- SLAM navigation based on shelf numbers (Aisle-Bay-Level) in warehouse corridors
- Model
- RFID Signal Strength Triangulation and Stock Deviation Anomaly Detection
- Integration
- WMS (Warehouse Management System) and SAP/Oracle ERP 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.
