| Summary | The number of highway bridges in the Taiwan area is over 25,000, and the average age of each bridge is nearly 20. The work load of inspection and maintenance increases with bridge age. The bridge inspector used now has the shortcomings of high cost, huge body and difficult operation. Besides, huge risk occurs in the inspection procedure in which a worker is placed underneath the bridge. This project thus develops a prototype bridge inspector carried by vehicle to inspect bridges in a fast, economic and safe way. Based on the experience and results of projects from 2007 & 2008, developing the bridge inspector, this project further focuses on photography definition, crack length calculation, vision dead angles, and inspection positioning to enhance functions of the bridge inspector prototype. The robot’s structure is analyzed using the finite element method. Field tests were taken on Chang-Tang Bridge (Provincial Highway No. 2C) to validate the operation process of the bridge inspector and examine the photograph quality under static and moving conditions. Field tests showed that the bridge inspector developed by this project satisfied the requirement of inspection for a screening tool, and provided of great economic benefit to bridge inspection with a cost of less than NT. 800,000. |
