Carnegie Mellon University and Sikorsky used an autonomous helicopter and an autonomous ground vehicle in UGV/UAV Joint Autonomy demonstration for the US Army
UGV/UAV Joint Autonomy demonstration for US Army
Carnegie Mellon University, January 20, 2016 - By Byron Spice - Carnegie Mellon University and Sikorsky Aircraft researchers have used an autonomous helicopter and an autonomous ground vehicle to demonstrate for the U.S. Army that ground and air robots can perform complex, cooperative missions.
A Black Hawk helicopter equipped for autonomous operation by Sikorsky, a Lockheed Martin Co., delivered a Land Tamer autonomous unmanned ground vehicle from CMU's National Robotics Engineering Center to a remote site, where the vehicle performed environmental monitoring for potential contamination.

Such a robotic mission could prevent warfighters' exposure to hazardous conditions, such as chemically or radiologically contaminated areas.
"We were able to demonstrate a new technological capability that combines the strengths of air and ground vehicles," said Jeremy Searock, NREC technical project manager. "The helicopter provides long-range capability and access to remote areas, while the ground vehicle has long endurance and high-precision sensing."
The Oct. 27 demonstration for the Army's Tank Automotive Research, Development and Engineering Center (TARDEC) took place at Sikorsky's Development Flight Center in West Palm Beach, Fla. NREC led the 19-month project, which was called Extending the Reach of the Warfighter Through Robotics.
In the demonstration, a Black Hawk helicopter equipped with Sikorsky's Matrix autonomy kit flew NREC's Land Tamer all-terrain vehicle, slung beneath the aircraft in a specially designed cage, to a remote area.
Once the helicopter lowered the vehicle to the ground, the Land Tamer drove itself off its transport platform to commence its leg of the mission. The vehicle, equipped with sensors for detecting chemical, biological, radiological or nuclear contamination, then found and surveyed several potentially contaminated sites, autonomously traversing six miles in the process.
When the vehicle sensors detected potential contamination, operators were able to switch the vehicle from autonomous operation into a tele-operated mode for a more detailed exploration of the site.
"The teaming of unmanned aerial vehicles and unmanned ground vehicles, as demonstrated here, has enormous potential to bring the future ground commander an adaptable, modular, responsive and smart capability that can evolve as quickly as needed to meet a constantly changing threat," said Paul Rogers, TARDEC director. "The cooperative effort between the Army labs, academia and industry to bring solutions to the warfighter is exciting to see."
NREC has extensive experience in unmanned ground vehicles, having developed the unmanned Crusher off-road vehicle for the Defense Advanced Research Projects Agency (DARPA), the Advanced Platform Demonstrator for TARDEC and a tactical unmanned ground vehicle, called Gladiator, for the U.S. Marines, as well as advanced off-road autonomous driving technology. NREC was also part of CMU's Tartan Racing Team that won the $2 million 2007 DARPA Urban Challenge robot race with its autonomous SUV called Boss.
The Black Hawk helicopter used in the demonstration was a UH-60MU model, equipped for "fly-by-wire" operation. Sikorsky installed its Matrix technology, which it has been developing since 2013.
"We invested in Matrix technology because we knew it would mean that, in certain scenarios, the warfighter can be kept out of harm's way and would be able to perform more missions and perform them more effectively," said Mark Miller, vice president of research and engineering at Sikorsky. "This demonstration indicated just that."
"This project was a great partnership between Carnegie Mellon and Sikorsky Aircraft," Searock said. "It was rewarding for our engineers to work with Sikorsky's team to create a new capability that will benefit our military forces."
