The digitization of the automated steel construction through the application of microcontrollers and MQTT

Abstract

Data acquisition and transfer are crucial aspects of the digitization and automation of construction workflows. Through the integration of microcontrollers in machinery, a multitude of data can be acquired and analyzed to adapt fabrication processes and optimize performance. The goal of this research was to develop connected multi-functional robotic systems that can transfer data across a wireless network through MQTT, a robust and lightweight IoT communication protocol. This research demonstrates a use case for such interconnected robotic technology by establishing wireless communication through MQTT between a mobile robot and a plasma cutting station. A microcontroller was utilized in the digitization and automation of this steel construction process to obtain, process and transfer the data in a way that was monitorable and storable for managing and optimizing workflows.
