Case Studies
Intelligent Tool Cart Gateway
26 Jun 2026Industrial IoT gateway for RFID tool data, Modbus/MQTT communication, cloud upload, and AGV movement coordination.
Overview
ChallengesThe main challenges were
- The tool cart needed to communicate with multiple RFID-equipped tools, upload the acquired tool data to a cloud server, and issue movement commands to the AGV carrying it around the factory floor
- The gateway also had to handle industrial data acquisition, protocol translation, cloud communication, and rugged day-to-day operation, all from one device
ObjectivesThe system needed to
- Collect intelligent-tool RFID and status data
- support Modbus communication across multiple tool connections at once
- send data to the cloud using MQTT
- simplify implementation without needing extra protocol converters bolted on
Solution DeliveredThe solution included
- An industrial IoT gateway was installed directly in the intelligent tool cart/AGV to handle the whole data path in one device
- It collected RFID and tool status data over Modbus, acting as a master polling each connected tool in turn, and then re-published that same data to the cloud over MQTT — meaning a single edge device handled both the shop-floor protocol (Modbus) and the cloud protocol (MQTT) without a separate converter box in between
- That consolidation is what kept the tool cart's electronics compact enough to actually fit on a mobile AGV platform

Conclusion
This story is compelling because it joins robotics, AGV movement, tool traceability, and predictive maintenance in one edge gateway application. It shows how a small gateway can become the data bridge between OT equipment and factory cloud systems.
