Description
A wireless sensing device recently developed by PI Wang’s group has demonstrated various structural sensing capabilities for bridge applications. In the meantime, a latest robot platform developed by Dr. La’s group at the University of Nevada, Reno (UNR) demonstrates promising performance navigating on steel bridge members. Marrying the two state-of-the-art developments, this project will produce a magnet-wheeled robot capable of autonomous nondestructive measurement on steel bridge structures. Both laboratory and field validations will be performed.
This project will integrate advanced wireless sensing technologies to the UNR robot platform. At first, the functionality of ultrasonic thickness measurement will be developed on the mobile platform. The ultrasonic thickness measurement only requires access to one side of an object, and can achieve sub-millimeter accuracy. The technique can be used for corrosion and defect detection, e.g. on the web and flanges of an I-beam. In addition, vibration measurements will be added to the robotic platform as well; potential applications include tension estimation in steel strands of cable-supported structures.
