It\u2019s a partnership with the University of Nebraska\u2019s National Strategic Research Institute. <\/p>\n\n\n\n<p>Project leader Carrick Detweiler\u2019s team aims to help the U.S. military monitor enemy weapon caches and perimeters by sending drones to plant sensors. The sensors will wirelessly communicate movement, increasing surveillance capabilities and reducing risks to soldiers. <\/p>\n\n\n\n<p>\u201cThere\u2019s a lot of pieces in this project,\u201d said Detweiler, associate professor of computer science and engineering. \u201cWe\u2019ve really had to focus on robustness and reliability at every stage of the system.\u201d <\/p>\n\n\n\n<p>One major challenge was developing a drone and payload system light enough for long-distance travel yet capable of drilling, which requires downward force.<\/p>\n\n\n\n<p>Clever engineering and optimized materials overcame a drone prone to spinning instead of drilling. <\/p>\n\n\n\n<p>Another challenge: The drone must be launched midair, such as from a larger drone or airplane. Researchers designed a system that can deploy and shed a parachute, spread its rotors and complete the mission. <\/p>\n\n\n\n<p>\u201cWe\u2019ve had to make it generic enough so that it can hitch a ride on any vehicle,\u201d Detweiler said. \u201cBasically, if they throw it out the door, it has to be able to recover and get to the right place.\u201d <\/p>\n\n\n\n<p>Stealth is also key. His team is working on a camouflaged exterior and less noticeable flight path, among other approaches. <\/p>\n\n\n\n<p>Finally, failure is not an option. If the drilling drone gets stuck, it\u2019s irretrievable and exposed. The team developed algorithms to abort or try a new spot within seconds if success is unlikely. <\/p>\n\n\n\n<p>Other applications include deploying remote sensors to monitor agricultural fields or detect environmental hazards in soil and water.<\/p>\n\n\n\n<ul class=\"wp-block-gallery columns-3 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"1057\" height=\"1600\" src=\"http:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_003_1.jpg\" alt=\"\" data-id=\"259\" data-link=\"http:\/\/research.unl.edu\/annualreport\/2018\/stealth-drilling-drone-could-help-military\/detweiler_or-2018_003_1\/\" class=\"wp-image-259\" srcset=\"https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_003_1.jpg 1057w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_003_1-198x300.jpg 198w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_003_1-768x1163.jpg 768w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_003_1-676x1024.jpg 676w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><figcaption>Drone close-up<\/figcaption><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"1047\" height=\"1600\" src=\"http:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_060.jpg\" alt=\"\" data-id=\"261\" data-link=\"http:\/\/research.unl.edu\/annualreport\/2018\/stealth-drilling-drone-could-help-military\/detweiler_or-2018_060\/\" class=\"wp-image-261\" srcset=\"https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_060.jpg 1047w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_060-196x300.jpg 196w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_060-768x1174.jpg 768w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_060-670x1024.jpg 670w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><figcaption> <br\/>Drone with drill probe attached <\/figcaption><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"1068\" height=\"1600\" src=\"http:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_038.jpg\" alt=\"\" data-id=\"264\" data-link=\"http:\/\/research.unl.edu\/annualreport\/2018\/stealth-drilling-drone-could-help-military\/detweiler_or-2018_038\/\" class=\"wp-image-264\" srcset=\"https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_038.jpg 1068w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_038-200x300.jpg 200w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_038-768x1151.jpg 768w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_038-684x1024.jpg 684w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><figcaption>A box containing a smaller drone, equipped with a parachute, will detach midair.<\/figcaption><\/figure><\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image fullWidth\"><img loading=\"lazy\" decoding=\"async\" width=\"1600\" height=\"1068\" src=\"http:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_081_1.jpg\" alt=\"\" class=\"wp-image-262\" srcset=\"https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_081_1.jpg 1600w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_081_1-300x200.jpg 300w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_081_1-768x513.jpg 768w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_081_1-1024x684.jpg 1024w, https:\/\/research.unl.edu\/annualreport\/2018\/wp-content\/uploads\/2018\/10\/Detweiler_OR-2018_081_1-1200x801.jpg 1200w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-has-aspect-ratio wp-embed-aspect-16-9\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" width=\"840\" height=\"473\" src=\"https:\/\/www.youtube.com\/embed\/c89szxtmCT4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer;
