Electronic implants in the brain or other parts of the body may be more efficient and effective due to a recent breakthrough by researchers at the University of Delaware. The advance potentially offers a wide array of biotechnology benefits and could also allow humans to control unmanned vehicles and other technologies with the brain.

Manned-unmanned teaming technologies being assessed in a weeks-long experiment are receiving mostly positive reviews from Army officials and non-commissioned officers.

The Next Generation Combat Vehicle Cross-Functional Team and Combat Capabilities Development Command’s Ground Vehicle Systems Center are conducting soldier operational experiments at Ft. Carson, Colorado, from June 15 through August 14. The goal is to observe, collect and analyze feedback from soldiers to assess the feasibility of integrating unmanned vehicles into ground combat formations.

Robots may one day learn to perform complex tasks simply by watching humans accomplish those tasks. That ability will allow people without programming skills to teach artificial intelligence systems to conduct certain functions or missions.

Teaching artificial intelligence systems or robots usually requires software engineers. Those programmers normally interview domain experts on what they need the machines to do and then translate that information into programming language, explains Ankit Shah, a graduate student in the Department of Aeronautics and Astronautics (AeroAstro) and the Interactive Robotics Group at Massachusetts Institute of Technology (MIT).

Scientists conducting basic research at the Johns Hopkins University Applied Physics Laboratory are examining how to build characteristics into a robotic system to improve human-nonhuman teaming. While artificial intelligence and machine learning applications can be trained to perform a task, those kinds of systems are not yet able to collaborate with humans and cannot anticipate human intent or what they will do.

In 1991, as part of an education program I was taking, I had an opportunity to visit several factories that were using robotics. That included visits to an automobile assembly factory in Kentucky and a Hitachi assembly plant in Japan. I was impressed with the precision and efficiency of the robots I saw in those plants. At the time, factory robots performed mostly routine, repetitive or dangerous tasks. They saved time and money, provided precision assembly and improved productivity, in part by reducing human errors. They precisely drilled every hole for every rivet.

The Army Research Laboratory (ARL) is handing its robotics research in adaptive autonomy to eight partners in academia and industry in what laboratory officials describe as a sprint to develop new capabilities. The Army has awarded $2.9 million in first-year funding as part of its Scalable, Adaptive and Resilient Autonomy (SARA) program to develop methods by which future Army robots can autonomously navigate rough terrain and avoid being blocked or upended by obstacles.

The U.S. Army announced today that it has canceled the solicitation for the Section 804 Middle Tier Acquisition (MTA) Rapid Prototyping phase of the Optionally Manned Fighting Vehicle (OMFV). Based on feedback and proposals received from industry, the Army has determined it is necessary to revisit the requirements, acquisition strategy and schedule before moving forward. 

"We remain committed to the OMFV program as it is our second-highest modernization priority, and the need for this ground combat vehicle capability is real. It is imperative we get it right for our soldiers," Dr. Bruce Jette, assistant secretary of the Army for Acquisition, Logistics and Technology, says in a written announcement. 

Advances in sensor mechanics and the advent of artificial intelligence have cleared the way for robots to play an increasingly greater role in military operations. Their growing versatility allows them to serve multiple functions in the military, from basic assistance to assumption of full combat roles. They can inter alia, lighten a warfighter’s load, provide search and rescue capabilities, perform surveillance missions, engage in casual evacuation, provide resupply and conduct hazardous route reconnaissance. Within 10 years, we may see them driving supply vehicles in convoys.

Secretary of the Army Ryan D. McCarthy has approved a new policy on advanced manufacturing designed to help the Army secure a competitive edge against near-peer adversaries.

Nanosized robots capable of crawling around on a person’s brain or underneath the skin may sound like a nightmare to some, but researchers suggest the mini machines could serve medical purposes such as gathering data on the brain or the spinal column.

Defense Advanced Research Projects Agency (DARPA) officials will include a panel discussion on ethics and legal issues at the Artificial Intelligence (AI) Colloquium being held March 6-7 in Alexandria, Virginia.

“We’re looking at the ethical, legal and social implications of our technologies, particularly as they become powerful and democratized in a way,” reveals John Everett, deputy director of DARPA’s Information Innovation Office.

Endeavor Robotics Inc., Chelmsford, Massachusetts, was awarded a $32,400,000 firm-fixed-price contract for reset, sustainment, maintenance, and recap parts for Robot Logistics Support Center technicians to support the overall sustainment actions of the entire Endeavor family of small, medium, and large robots. Bids were solicited via the internet with one received. Work locations and funding will be determined with each order, with an estimated completion date of January 2, 2024. U.S. Army Contracting Command, Warren, Michigan, is the contracting activity (W56HZV-19-D-0031).

A research team at the University of Texas at Arlington may one day cover robots and prosthetic devices with nanotechnology skin to provide them with a sense of touch far superior to humans.

A sense of touch could allow for greater precision and control. A robot needs to know, for example, how much pressure to apply when picking up an elderly patient from a bed, an airplane engine from a factory floor, or a glass of champagne from a tabletop.

The novelty of a robot joining warfighters on the battlefield has worn off, and the U.S. Marines are settling in to make their use of autonomous systems more effective. The service cannot afford to have robots that hinder operations, an expert says.

The Science and Technology Division of the Marine Corps Warfighting Laboratory is considering robotic systems that lighten cognitive or physical burdens for Marines. Researchers are advancing robotic or autonomous machines not just for the infantry but for medical and logistics units as well.

The U.S. Naval Research Laboratory’s (NRL’s) work on its Meso-scale Robotic Locomotion Initiative, known as MERLIN, is advancing, reports NRL roboticist Glen Henshaw. The shoebox-size quadruped robot, meant to weigh in at 10 kilograms (22 pounds), features hydraulic-based legs for running, jumping or climbing—to navigate environments too complicated for tracked or wheeled robots.

And after several years of development, MERLIN is almost walking, Henshaw says.

The past three decades have seen technologies rapidly transform the face of society. Robots, coupled with artificial intelligence, machine learning and other developing capabilities such as the Internet of Things (IoT), are among the latest technologies to offer the promise of labor-saving capabilities, improved efficiency in manufacturing, better precision in the medical field and enhanced capabilities in national security, to name just a few applications.

Over the last decade, emergency responders have increasingly relied on robots to assist with public safety functions that may be too dangerous for humans. Autonomous systems can perform search and rescue tasks, provide decision support, transport medical supplies, extinguish fires, map disaster areas or accomplish other important rescue functions.

The Defense Advanced Research Projects Agency (DARPA) is moving into the first development phase of its OFFensive Swarm-Enabled Tactics (OFFSET) program, a capability that will empower dismounted troops to control scores of unmanned air and ground vehicles simultaneously. Once fully evolved, the technology will provide small-unit infantry forces with small, unmanned aircraft and ground systems to support diverse missions in urban areas. The program also seeks to integrate modern swarm tactics and leverage emerging technologies in swarm autonomy and human-swarm teaming.

Within five years, the Army would like to start testing remote combat vehicle (RCV) prototypes that are as light and as fast as a Stryker but provide the same level of firepower as an M-1 Abrams tank, according to a service press release.

While the holy grail is the Next Generation Combat Vehicle (NGCV), the Army thinks it can more quickly field a limited number of RCVs, and importantly, the results of that testing could help inform the requirements for the NGCV, which is slated for fielding in 2035.

The U.S. Air Force’s most prolific scientist likely will never wear a lab coat, but it can perform experiments 100 times faster than its human counterparts. The robo-researcher may one day help spark explosive growth in scientific knowledge.

The Air Force Research Laboratory’s (AFRL’s) Autonomous Research System (ARES) does not fit the conventional idea of a robotic system. It is not humanoid. It does not move freely across the ground or fly through the air. But in a single day, it can autonomously execute 100 experiments, compared with about one for its human peers.

U.S. Army scientists and engineers recently designed an aluminum nanomaterial that produces high amounts of energy when it comes in contact with water, or any liquid containing water. Since the nanomaterial powder has the potential to be 3-D printed, researchers envision future air and ground robots that can feed off of their very structures and self-destruct after mission completion. Another possible application of the discovery that may help future soldiers is the potential to recharge mobile devices for recon teams.

Robots have done their fair share of safeguarding troops on the battlefield, from defusing bombs to scouting out caves for insurgents. In spite of their success, or perhaps because of it, the U.S. Defense Department now wants its unmanned ground vehicles to be more than one-trick ponies. 

Researchers are planning the inaugural test flight of a cyborg dragonfly, a brand-new type of micro aerial vehicle. Harnessing the power of nature, the hybrid system is smaller, lighter and stealthier than most man-made systems and could prove valuable for military reconnaissance and a variety of other missions. 

Scientists with The Charles Stark Draper Laboratory Inc., Cambridge, Massachusetts, and the Howard Hughes Medical Institute (HHMI), Ashburn, Virginia, are partnering on a Draper-funded project known as DragonflEye. 

Today’s ruggedized robots will go where man has gone before—and where man should no longer have to go. While U.S. defense officials are not ready to fully relinquish warfighting duties to robots, they are on the fast track to acquiring technologies and platforms anticipated to shake up military operations.
