Army discovery opens path to safer batteries
Soldiers carrying 15-25 pounds of batteries could carry batteries a fraction of the weight but with the same energy and improved safety, a new study shows.
Converting Wi-Fi signals to electricity with new 2-D materials
Imagine a world where smartphones, laptops, wearables, and other electronics are powered without batteries. Researchers from MIT and elsewhere have taken a step in that direction, with the first fully flexible device that can convert energy from Wi-Fi signals into electricity that could power electronics.
Small flying robots haul heavy loads
A closed door is just one of many obstacles that poses no barrier to a new type of flying, micro, tugging robot called a FlyCroTug. Outfitted with advanced gripping technologies and the ability to move and pull on objects around it, two FlyCroTugs can jointly lasso the door handle and heave the door open.
World's first 3D volumetric circuit
Research on the 3D/volumetric circuit technology was borne out of the notion that a three-dimensional circuit offers more freedom to make circuits smaller, lighter and more efficient. 3D printing allows them to be manufactured into arbitrary form factors that can be integrated into any object or surface.
If military robot falls, it can get itself up
Scientists at the U.S. Army Research Laboratory and the Johns Hopkins University Applied Physics Laboratory have developed software to ensure that if a robot falls, it can get itself back up, meaning future military robots will be less reliant on their Soldier handlers.
Water bottles and other recycled 3D printing materials
Soldiers on the battlefield or at remote bases often have to wait weeks for vital replacement parts. Now scientists report they have found a way to fabricate many of these parts within hours under combat conditions using water bottles, cardboard and other recyclable materials.
Introducing the latest in textiles: Soft hardware
The latest development in textiles and fibers is a kind of soft hardware that you can wear: cloth that has electronic devices built right into it.
A higher-energy, safer and longer-lasting zinc battery
A team of researchers has created a water-based zinc battery that is simultaneously powerful, rechargeable, and intrinsically safe.
Invertebrates inspire first fully 3-D printed active materials
To overcome the material rigidity and actuation limitations in current robotic systems, a joint U.S. Army Research Laboratory and University of Minnesota research project sought inspiration from invertebrates.
Scientists mimic neural tissue
Researchers have discovered a process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue. The breakthrough material may lead to autonomous soft robotics, dual sensors and actuators for soft exoskeletons, or artificial skins.
New algorithms to train robots
Researchers have developed new techniques for robots or computer programs to learn how to perform tasks by interacting with a human instructor.
Army partners with Marine Corps on 3-D printed drones
Army researchers are working with the Marines to develop 3-D printed drones as materials science, aviation technology and software development merge to deliver new capabilities.
Engineers to develop intelligent, adaptive and resilient robot teams
The United States Army Research Laboratory has awarded a five-year, $27 million grant to develop new methods of creating autonomous, intelligent, and resilient teams of robots.
Water-based lithium-ion batteries without explosive risks now reality
Researchers have developed for the first time a lithium-ion battery that uses a water-salt solution as its electrolyte and reaches the 4.0 volt mark desired for household electronics, such as laptop computers, without the fire and explosive risks associated with some commercially available non-aqueous lithium-ion batteries.
Army discovery may offer new energy source
Army scientists and engineers recently made a groundbreaking discovery -- an aluminum nanomaterial of their design produces high amounts of energy when it comes in contact with water, or with any liquid containing water.
Strengthening 3D printed parts for real-world use
Researchers have discovered a way to make 3-D printed parts stronger and immediately useful in real-world applications.
