UAS-RX: Design and Field Experiments of a micro-UAS for Prescribed Fire Ignition
January 20, 2017
Unmanned Aerial System (UASs) are increasingly being used for everything from crop surveying to pipeline monitoring. They are significantly cheaper than the traditional manned airplane or helicopter approaches to obtaining aerial imagery and sensor data. The next generation of UASs, however, will do more than simply observe. In this talk, I will discuss recent advances we have made in the Nimbus Lab in developing the first UAS that can ignite prescribed fires. Prescribed fire is a critical tool used to improve habitats, combat invasive species, and reduce fuels to prevent wildfires. In the United States alone federal and state governments use prescribed burns on over 3 million acres each year, with private land owners prescribing even more. Yet this activity can be extremely dangerous, especially when performing interior ignitions in difficult terrain. In this talk, I will discuss the history of this project and the challenges associated with flying near and igniting fires. In addition, I will detail the mechanical and software design challenges we have had to overcome in this project. I will also present the results of the first two prescribed burns that were successfully ignited by a UAS. Finally, I will discuss automated software analysis techniques we are developing to detect and correct system errors to reduce risk and increase safety when using UASs to ignite prescribed burns.
Dr. Carrick Detweiler is an Associate Professor in the Computer Science and Engineering department at the University of Nebraska-Lincoln. He co-directs and co-founded the Nebraska Intelligent MoBile Unmanned Systems (NIMBUS) Lab at UNL. His research focuses on improving the robustness and safety of aerial robots and sensor systems operating in the wild. Carrick obtained his B.A. in 2004 from Middlebury College and his Ph.D. in 2010 from MIT CSAIL. He is a Faculty Fellow at the Robert B. Daugherty Water for Food Institute at UNL and recently received the 2016 College of Engineering Edgerton Innovation Award. He is currently leading NSF and USDA projects focused on developing the systems and software to enable interactions of UAVs with water, fire, and crops. In addition to research activities, Carrick actively promotes the use of robotics in the arts through workshops and collaborations with the international dance companies Pilobolus and STREB.
