The demonstration system uses onboard computers running advanced collaborative-vehicle software -- along with novel sensors and open standards-based communications and interfaces -- to create an autonomous system with unique capabilities. \u003C\/p\u003E\u003Cp\u003EGTRI\u0027s CUSTD system will take part in Robotics Rodeo 2010, scheduled for Oct. 12-15 at Fort Benning, Ga. The Rodeo is hosted by the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC), based near Detroit. A number of invited robotic-research teams will demonstrate their work at the event. \u003C\/p\u003E\u003Cp\u003E\u0022We believe our system represents the leading edge of demonstrating collaborative autonomous vehicle capabilities,\u0022 said Lora Weiss, a principal research engineer who is a member of GTRI\u0027s Unmanned and Autonomous Systems team. \u0022This system demonstrates not only the collaborative interoperability possible among dissimilar vehicles, but also the numerous sensing technologies that can be included onboard as interchangeable payloads -- chemical and infrared sensors, still and video cameras, and sophisticated signal- and data-processing.\u0022 \u003C\/p\u003E\u003Cp\u003EThe GTRI system uses two unmanned aerial vehicles (UAVs) that have nine-foot wingspans, seven-pound scientific-instrument payloads, and global positioning systems (GPS) for navigation. The unmanned ground vehicle (UGV) is a full-size Porsche Cayenne. \u003C\/p\u003E\u003Cp\u003EThe aircraft require human guidance during takeoff, but while aloft they become autonomous for both navigation and target-locating tasks. The Porsche -- the same \u201cSting\u201d vehicle entered by Georgia Tech in the DARPA Urban Challenge -- is fully autonomous. \u003C\/p\u003E\u003Cp\u003E\u0022The vehicles\u0027 very dissimilarity helps them collaborate effectively,\u0022 said Charles Pippin, a GTRI research scientist who led the CUSTD effort. \u003C\/p\u003E\u003Cp\u003EFast-moving unmanned air vehicles, he explained, can find targets over a wide area, but their altitude and the limitations of their lightweight sensors can lessen the quality of gathered data. However, the UAVs can call in an unmanned ground vehicle -- equipped with large, complex sensors and cameras -- to analyze the target location more fully. \u003C\/p\u003E\u003Cp\u003EPersonnel from several GTRI units have participated in the CUSTD effort, said Pippin, who like Weiss is a member of GTRI\u0027s Unmanned and Autonomous Systems team. CUSTD\u0027s current capabilities are based on extensive research and testing, including more than 50 test flights conducted at Fort Benning and other locations throughout the past year. \u003C\/p\u003E\u003Cp\u003EA demonstration opportunity such as the Robotics Rodeo, Pippin said, allows researchers to dramatize how well multiple autonomous robots can now collaborate. \u003C\/p\u003E\u003Cp\u003E\u0022It\u0027s hard to illustrate the effectiveness of collaborative interoperability and autonomy algorithms in a simulation,\u0022 he said. \u0022When onlookers see the technology demonstrated on hardware platforms, then it becomes very real.\u0022 \u003C\/p\u003E\u003Cp\u003EIn a typical CUSTD scenario, the two aircraft search for an existing target over a wide area. When one plane spots the target, it radios its location using GPS coordinates to the unmanned ground vehicle, which then finds its way around buildings and along roads to the target. \u003C\/p\u003E\u003Cp\u003EAt the same time, the unmanned air vehicle over the target can ask the second aircraft to fly to the target and use its sensors to further analyze the situation. Such flexibility can be important, Pippin said, because UAVs are often outfitted with different sensors due to weight and cost considerations. \u003C\/p\u003E\u003Cp\u003EOne technique that is still under development at GTRI -- and is proving valuable for vehicle collaboration -- is called market-based auctions, Pippin said. This approach uses an \u0022auction\u0022 type of algorithm that lets robotic vehicles \u0022bid\u0022 on a given task. Using this method, unmanned vehicles can autonomously divide up work on the spot in the most efficient way. \u003C\/p\u003E\u003Cp\u003EIn an auction-technology scenario, an unmanned air vehicle over a target might send out a bid to other nearby UAVs, asking which among those airplanes that are outfitted with a particular sensor is closest to the target. The UAV that best complies with both requirements \u2013 equipment and proximity -- wins the bid. \u003C\/p\u003E\u003Cp\u003EIn a GTRI experiment, unmanned air vehicles using a market-based approach reduced the travel required to complete a task by nearly 50 percent. The result was a substantial saving in both time and fuel. \u003C\/p\u003E\u003Cp\u003EWeiss explained that GTRI\u0027s CUSTD system is standards compliant, an important consideration in current defense-technology development. All GTRI autonomous-system designs now comply with the Standard Interface of the Unmanned Control System for NATO UAV interoperability (STANAG 4586) and with the Joint Architecture for Unmanned Systems (JAUS) scripting language. \u003C\/p\u003E\u003Cp\u003E\u0022By developing these systems to be STANAG and JAUS compliant, we\u0027re building in future interoperability with other unmanned systems produced by different vendors,\u0022 Weiss said. \u0022If upcoming systems are going to be able to communicate, as well as operate with the control-system designs now being developed, they\u2019ll need to be standards compliant.\u0022 \u003C\/p\u003E\u003Cp\u003EThe CUSTD system also makes use of FalconView\u2122, a Windows-based mapping application developed by GTRI for the Department of Defense. FalconView supports many map types, such as aeronautical charts, satellite images and elevation maps. FalconView can be used by a ground-based station to monitor and control the system. \u003C\/p\u003E\u003Cp\u003EIn the past several years, GTRI has been bringing autonomous vehicle research under one umbrella that includes all aspects of systems-payload, sensor, autonomy logic and collaborative operations. Research now also includes unmanned underwater vehicles and space vehicles. \u003C\/p\u003E\u003Cp\u003EThe Robotics Rodeo will consist of two separate events. The Extravaganza is open to the public. The Robotic Technology Observation, Demonstration and Discussion (RTOD2), closed to the public, allows research teams to demonstrate their technologies to government observers and contractors. \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003EGeorgia Institute of Technology\u003Cbr \/\u003E75 Fifth Street, N.W., Suite 314\u003Cbr \/\u003EAtlanta, Georgia 30318 USA\u003C\/strong\u003E \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contacts\u003C\/strong\u003E: Kirk Englehardt (404-407-7280)(\u003Ca href=\u0022mailto:kirk.englehardt@gtri.gatech.edu\u0022\u003Ekirk.englehardt@gtri.gatech.edu\u003C\/a\u003E) or John Toon (404-894-6986)(\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E) or Abby Vogel Robinson (404-385-3364). \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: Rick Robinson \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EResearchers at the Georgia Tech Research Institute (GTRI) are showing the U.S. Army an advanced approach to enabling autonomous collaboration among dissimilar robotic vehicles.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Engineers are demonstrating collaboration of air \u0026 ground vehicles."}],"uid":"27303","created_gmt":"2010-10-12 00:00:00","changed_gmt":"2016-10-08 03:04:08","author":"John Toon","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2010-10-12T00:00:00-04:00","iso_date":"2010-10-12T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"62113":{"id":"62113","type":"image","title":"Three robotic vehicles","body":null,"created":"1449176355","gmt_created":"2015-12-03 20:59:15","changed":"1475894471","gmt_changed":"2016-10-08 02:41:11","alt":"Three robotic vehicles","file":{"fid":"191398","name":"tbg15582.jpg","image_path":"\/sites\/default\/files\/images\/tbg15582_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/tbg15582_0.jpg","mime":"image\/jpeg","size":412588,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/tbg15582_0.jpg?itok=gYRulYmw"}},"62114":{"id":"62114","type":"image","title":"Inspecting robotic aircraft","body":null,"created":"1449176355","gmt_created":"2015-12-03 20:59:15","changed":"1475894471","gmt_changed":"2016-10-08 02:41:11","alt":"Inspecting robotic aircraft","file":{"fid":"191399","name":"tiq15582.jpg","image_path":"\/sites\/default\/files\/images\/tiq15582_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/tiq15582_0.jpg","mime":"image\/jpeg","size":1311341,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/tiq15582_0.jpg?itok=2jKKCMwc"}},"62115":{"id":"62115","type":"image","title":"Preflight inspection of aircraft","body":null,"created":"1449176355","gmt_created":"2015-12-03 20:59:15","changed":"1475894481","gmt_changed":"2016-10-08 02:41:21","alt":"Preflight inspection of aircraft","file":{"fid":"191400","name":"tbv15582.jpg","image_path":"\/sites\/default\/files\/images\/tbv15582_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/tbv15582_0.jpg","mime":"image\/jpeg","size":1516289,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/tbv15582_0.jpg?itok=9nPbCQlf"}}},"media_ids":["62113","62114","62115"],"related_links":[{"url":"http:\/\/www.gtri.gatech.edu\/","title":"Georgia Tech Research Institute"}],"groups":[{"id":"1188","name":"Research Horizons"}],"categories":[{"id":"136","name":"Aerospace"},{"id":"145","name":"Engineering"},{"id":"147","name":"Military Technology"},{"id":"135","name":"Research"}],"keywords":[{"id":"1833","name":"aircraft"},{"id":"7264","name":"autonomous"},{"id":"10939","name":"collaborate"},{"id":"2552","name":"robotic"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Cstrong\u003EJohn Toon\u003C\/strong\u003E\u003Cbr \/\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=jt7\u0022\u003EContact John Toon\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-6986\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"email":["jtoon@gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
