On-site UAT
TW Engineering built the Warehouse Control System (WCS) that commands and integrates the Mobile Racking System (MRS) and AGV fleet in three Hong Kong International Airport stores (T1, T1M and AGMB), working with the project’s main contractor, who supplied the racking and robots.
Problem
The challenge
The airport stores needed one control layer that keeps mobile racking and AGVs working together around the clock, with safety interlocks and multi-level user permissions.
Solution
Solution — three layers
The system has three parts — TW is responsible for the WCS software and all integration:
02
Mobile Racking System (supplied by the main contractor)
- Pallets up to 1200×1200×1200mm, 1000kg each
- Internal wheel carriages rated for 24,000kg
- Minimum 5 m/min movement speed
- WCS-controlled, with on-rack and manual contingency modes
03
Warehouse Robot System / AGV (supplied by the main contractor)
- Tote-box AGVs with omnidirectional motion
- Speed: 1.6 m/s unloaded / 1.35 m/s loaded
- 30kg per tote, 120kg total capacity
- ±10mm navigation accuracy

Tech stack
TW’s part of the stack
- Windows-based local server (on-premises)
- Web UI with HTTPS
- LAN + Wi-Fi between WCS ↔ MRS ↔ AGV
- Robot RCS integration via API
- 4-level role-based access (Operator / Supervisor / Maintenance / Admin)
Outcome
What we delivered
Installed on site from December 2025 to March 2026, followed by on-site UAT in 2026. The WCS commands the racking and robots over the airport LAN/Wi-Fi.
Significance
Why this matters
01
International airport end customer
Airport Authority Hong Kong operates one of the busiest international airports in the world.
02
One WCS for three systems
TW’s software keeps mobile racking and AGVs from different vendors working as one system.
03
Factory test and on-site UAT
Factory acceptance testing in 2025, followed by on-site UAT at the airport in 2026.
