The Aurora Flight Sciences unmanned aerial vehicle will be integrated into a larger system that combines the flying device that can fit into a backpack with a software system that can discern an optimal flight pattern and transform the resulting data into three-dimensional maps. The project is an interdisciplinary collaboration between Vanderbilt archaeologist Steven Wernke and engineering professor Julie A. Adams.

They call it SUAVe – for Semi-autonomous Unmanned Aerial Vehicle. It was partially financed by an Interdisciplinary Discovery Grant from Vanderbilt.
"It can take two or three years to map one site in two dimensions," Wernke said. "The SUAVe (pronounced SWAH-vey) system should transform how we map large sites that take several seasons to document using traditional methods. It will provide much higher resolution imagery than even the best satellite imagery, and it will produce a detailed three-dimensional model." The SUAVe system is compact and is designed to be easy to use.
"You will unpack it, specify the area that you need it to cover and then launch it," Wernke said. "When it completes capturing the images, it lands and the images are downloaded, matched into a large mosaic, and transformed into a map."
The algorithms developed for the project allow the SUAVe system to specify the flight pattern to compensate for factors such as the wind speed, the angle of the sun and photographic details like image overlap and image resolution, Adams said.
"The only way for this system to be cost-effective is for it to be easy enough to operate that you don't need an engineer on every site," Adams said. "It has to be useable without on-site technical help."
Tests are scheduled from mid-July to mid-August at the abandoned colonial era town of Mawchu Llacta in Peru, and plans call to return next year after any issues that arise are addressed in the lab.
Built in the 1570s at a former Inca settlement and mysteriously abandoned in the 19th century, the village of Mawchu is a 45-minute hike for the team from the nearby village of Tuti. Mawchu Llacta is composed of standing architecture arranged in regular blocks covering about 25 football fields square.
"Archaeology is a spatial discipline," Wernke said. "We depend on accurate documentation of not just what artifacts were used in a given time period, but how they were used in their cultural context. In this sense, SUAVe can provide a fundamental toolset of wide significance in archaeological research."
Wernke hopes that the new technology will allow many archaeological sites to be catalogued very quickly, since many are being wiped away by development and time.
"The SUAVe system should be a way to create a digital archival registry of archaeological sites before it's too late," he said. "It will likely create the far more positive problem of having so much data that it will take some time go through it all properly."
SUAVe could also have other applications, including the tracking of the progress of global warming and as a tool for first responders at disaster sites.
"The device would be an excellent tool for evaluating the site of a major crisis such as Sept. 11 to decide how to deploy lifesaving resources more effectively," Adams said.
This research was partially supported by an NSF CAREER award, NSF #IIS-0643100.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
