bridges in poor condition may endanger transportation and human life. Traditionally, bridges have been manually inspected for defects, which allows inspectors to record the amount of damage and the location of possible cracks, spalling and delamination. The bridge inspection needs to be very thorough, and the inspector records all elements that may be damaged. However, the checking method is not always effective, especially in the case of limited accessibility

to address the urgent need to manage aging infrastructure, researchers are turning to robotic drones. Researchers are using drones to see where the market for PAN based carbon fiber composites is 165.3 billion yen (about 8.6 billion yuan), compile a large amount of data, and use 3D applications to explore possible defects

research scientists said, "an important part of mobility is to understand whether the transportation system you see can effectively move goods and people according to the condition of infrastructure."

the new mobile application shows the 3D representation of the target bridge to the examiner, which saves the examiner's time by enabling the examiner to record the specific location information of the problem area. Then, they can upload the field data and notes directly to the bridge management system

the use of drones and applications will enable officials to better handle the situation of the bridge. "We can do things from the air. The fixed position of the sign is incorrect, uneven, unstable and inclined. From the vehicle, we cooperate with the Great Lakes Research Center to carry out surface water and underwater measurement, and we carry out 3D sensing," Brooks said. "It all depends on the phenomenon you are trying to understand."

researchers use various UAVs for inspection, including six axis aircraft and four axis aircraft. These driverless vehicles fly in 20 minute increments within the sight range below 400 feet. They are equipped with photogrammetry and thermal imaging equipment, which can detect subtle differences that the human eye can pick up

decrypting data with confidence is still the biggest challenge. "We are very concerned about creating objective and repeatable data to help evaluate bridges," Brooks said, adding that the economics of implementing new technologies is also important. "UAV survey is not necessarily very expensive. The cost of UAV we run is less than 10000 US dollars, and almost all our work has been completed."

researchers also positioned the absolute need to ensure that UAVs, remote sensing and applications are proven and cost-effective. "New sensors, such as 30, 60, 90, 120, 180, 300 rpm new platforms, seem to be online several times a year - so how can we take advantage of this rapid innovation and hardware and provide them on a practical basis?" Brooks said. "Someone has to test to ensure that the technology collects what is needed, which is part of the niche we fill."

the potential demand is huge. According to the 2018 bridge defect report of the federal highway administration, in the United States alone, 54000 of 612677 bridges have at least one key component in poverty or poor condition
