Robotic Installation of Wireless Strain Gauges into Precast Concrete Elements

Abstract

This paper outlines our group's recent progress in the robotic deployment of wireless sensors within concrete precast elements. This study is focused on the automated installation of embedded vibrating wire strain gauges (VWSGs), interrogated by a wireless node. This paper outlines the initial development of our robotic process and the magnetic sensor packaging which is used to encapsulates wireless nodes and VWSGs. The system has been deployed onto an oiled metallic formwork, to simulate conditions found in precast factories. The magnetically attached sensor packaging can withstand loads imposed during the pouring of concrete and its vibration. The results of this pilot study are promising and could allow robotics to be successfully integrated into precast processes so that smart precast segments can be produced at scale.
