RoboCopters summoned by iPad apps are already in the works for U.S. Navy and Marines

By Grace Jean, Office of Naval Research

Marines running low on ammo may one day use an app on their digital handhelds to summon a robotic helicopter to deliver supplies within minutes, enabled by technologies from a new Office of Naval Research (ONR) program.

The Autonomous Aerial Cargo Utility System (AACUS) is a five-year, $98 million effort to develop sensors and control technologies for robotic vertical take-off and landing aircraft.

"AACUS is a leap-ahead technology that allows the Navy and the Marine Corps to move beyond having a highly trained operator fly an unmanned aircraft," says Rear Adm. Matthew Klunder, chief of naval research. "The program will let us leverage advanced autonomy, but still maintain the central and critical role of the human operator as the supervisor."

Marines based at outposts or in the field will be able to request the autonomous cargo helicopters for rapid resupply of combat essentials.

"We want to turn any helicopter into a logistics machine," says Dr. Mary "Missy" Cummings, program officer for AACUS, ONR's newest innovative naval prototype. "In the near term, we want to succeed in fully autonomous landings in austere locations, so Marines can get whatever they need on demand.

"In the long term, this could be a real life saver and revolutionize first response," she says. While rapid resupply is the immediate focus for AACUS, long-term applications could include critical medical missions such as casualty evacuation."

Program officials are seeking researchers who will develop threat- and obstacle-detection and avoidance systems, as well as autonomous landing capabilities that can operate across different types of aircraft. They expect teams from industry and academia to join forces to compete for the contracts.

Proposals are due Feb. 22. Officials plan to award up to two contracts in April.

The effort follows the Marine Corps Warfighting Laboratory's successful program to develop an unmanned system capable of hauling cargo semi-autonomously to landing zones at bases. The prototype, called K-MAX, flew its first combat mission in Afghanistan in mid-December, resupplying Marines with cargo carried in a sling-load.

AACUS, on the other hand, is aimed at internal load-carrying capacity. It will be a major leap ahead in autonomy, says Cummings. While K-MAX requires a trained operator within line-of-sight to fly, any operator will be able to call for AACUS from any location.

"It's going to be designed to work with people who have no flight experience," she says. "An operator will pick up his iPad or Android and make an emergency supply request. He'll request that the helicopter come to him and land as close to him as possible."

The helicopter not only will take off by itself, but will plan its own flight path and navigate its way through the airspace, requiring little to no input from an operator other than to verify its proposed landing site. The concept will require improvement in data processing.

"How you take the data from sensors and integrate them to make these decisions – that's one of the big leaps," says Cummings. "It's like putting a frontal lobe on the helicopter."
