A new method leverages AI and computer simulations to train robotic exoskeletons that can help users save energy while walking, running, and climbing stairs. The novel method rapidly develops exoskeleton controllers to assist locomotion without relying on lengthy human-involved experiments
New research pushes forward the bounds of stroke recovery with a unique robotic hip exoskeleton, designed as a training tool to improve walking function. This invites the possibility of new therapies that are more accessible and easier to translate from practice to daily life compared to current rehabilitation methods
Researchers have demonstrated a new technique for directly printing electronic circuits onto curved and corrugated surfaces. The work paves the way for a variety of new soft electronic technologies, and researchers have used the technique to create prototype smart contact lenses, pressure-sensitive latex gloves, and transparent electrodes
Instead of adding soft materials to a rigid robot body, researchers have taken a soft body and added rigid features to key components. The structures were inspired by insect exoskeletons, which have both soft and rigid parts. The “flexoskeletons” could lead to the creation of a new class of soft, bioinspired robots
This recommended practice establishes the procedures and requirements for cleaning titanium alloy parts prior to adhesive bonding operations
This document describes an inspection procedure for detecting, by use of a radiographic opaque tracer and fluoroscopy or radiography methods, flaws which have been produced as the result of cutting, machining, or drilling operations in composite or laminate structures
This document describes a manufacturing method for processing unidirectional carbon fiber/epoxy resin impregnated sheet and tape into multi-ply broadgoods and tape produced on an automated cross-plying machine. Broadgoods or tape of two or more ply configurations may be processed, where ply orientations of 0°, 45°, 90°, and 135° (as examples) may be automatically layed in a programmed sequence. In all configurations, the 0° ply direction is parallel to the length of the broadgoods roll or sheet, or tape
Elastic polymers, known as elastomers, can be stretched and released repeatedly and are used in applications such as gloves and heart valves, where they need to last a long time without tearing. But elastic polymers can be stiff, or they can be tough, but they can't be both. This stiffness-toughness conflict is a challenge for scientists developing polymers that could be used in applications including tissue regeneration, bioadhesives, bioprinting, wearable electronics, and soft robots
It’s no coincidence that our most complex, versatile, and useful body part, the human hand, is also among the most prone to injury. “The human hand and forearm are a marvel of capability for its size,” said Jonathan Rogers, a mechanical design engineer at NASA’s Johnson Space Center in Houston. So, it’s no surprise that one of the biggest obstacles to creating the first robot astronaut to fly in space was building its hands
Exoskeletons, many of which are powered by springs or motors, can cause pain or injury if their joints are not aligned with the user’s. To mitigate these risks, a new measurement method was developed to test whether an exoskeleton and the person wearing it are moving smoothly and in harmony
Researchers have developed a lighter, yet more robust knee brace for the elderly who suffer from knee problems. Using 3D printing techniques, the team has managed to reduce the weight of a traditional exoskeleton knee brace (typically built using metal) by 30 percent, thanks to an innovative design that uses lightweight plastic and assistive springs
Engineers designed a novel facemask that can diagnose the wearer with COVID-19 within about 90 minutes. The masks are embedded with tiny, disposable sensors that can be fitted into other face-masks and could also be adapted to detect other viruses
Paraplegia means a drastic change in the life of the person affected and their social environment. From one moment to the next, you lose a large part of your independence. Climbing stairs, getting up, getting from A to B or beloved hobbies: many things are only possible with the help of others. The Swiss company TWIICE has set itself the task of giving sufferers back a large part of their independence with the help of a modular exoskeleton — it makes even ski tours possible. To ensure that the exoskeleton functions reliably under all conditions, TWIICE relies on robust connectors
The current drone market holds a lot of low-cost drones that can be controlled either remotely or autonomously. The command controlling signals can be deployed by using different methods and techniques to enhance the capabilities and missions of the drone. The microcontroller is usually used as the drone brain. Motion control and virtual reality (VR) techniques allow the user new possibilities for a more dynamic control experience. The goal of the present work is to design, develop, and deliver a working prototype of an enhanced VR motion-controlled drone. The developed prototype is an integrated system that includes an off-the-shelf drone, accelerometer and gyroscope unit, flex sensor, gloves, digital potentiometer, VR headset, and microcontroller. The flex sensor attached to the hand gloves allows a fully autonomous control of the drone using the movement of the hand. Hence, the gloves will allow for a more dynamic control of the drone. Furthermore, the virtual headset is connected
Hydrogen peroxide has made headlines as researchers and medical centers around the country have been testing its viability in decontaminating N95 masks to deal with shortages amid the COVID-19 pandemic. While results so far are promising, some researchers worry that the chemical’s poor shelf life could make such decontamination efforts costly
Pressurized insertion of aqueous solutions into water-repellent nano-porous materials, such as zeolites and metal-organic frameworks, could help to create high-performance, energy-absorbing systems. Researchers experimented with hydrothermally stable zeolitic imidazolate frameworks (ZIFs) with a hydrophobic cage-like molecular structure, finding that such systems are remarkably effective energy absorbers at realistic, high-rate loading conditions and this phenomenon is associated with the water clustering and mobility in nanocages
While robots armored with hard exoskeletons are common, they’re not always ideal. Soft-bodied robots, inspired by fish or other soft creatures, might better adapt to changing environments and work more safely with people. Roboticists generally have to decide whether to design a hard- or soft-bodied robot for a particular task. But that tradeoff may no longer be necessary
Fabricated using flexible, stretchable, and electrically conductive nanomaterials called MXenes, novel strain sensors were developed that are ultra-thin, battery-free, and can transmit data wirelessly. By controlling the surface textures of MXenes, researchers were able to control the sensing performance of strain sensors for various soft exoskeletons. The sensor design principles developed will significantly enhance the performance of electronic skins and soft robots
According to research conducted by Markets and Markets (Northbrook, IL), the military wearables market is projected to grow from $4.2 billion in 2019 to $6.4 billion by 2025. That’s a 7.2% growth from 2019 in six short years. Soldier modernization programs that increase soldier coordination, rising asymmetric warfare, and potential geopolitical conflicts are all factors fueling the growth of this market

This research involved a new process developed to support the rapid development of computer-aided design (CAD) geometry to model personal protective equipment (PPE). The armor was developed and used in modeling and simulation for analysis of the Tier 4 Soldier Protection System (SPS) compared to the Improved Outer Tactical Vest (IOTV). The goal of modeling the PPE CAD geometry was to create a representation of the armor system to scale relative to the Operational Requirement-based Casualty Assessment (ORCA) man model and place the armor system in the correct location relative to anatomical landmarks
General criteria are presented as guidelines for: control device location, resistance, and actuation of hand and foot controls by the machine’s operator. The criteria are based upon physical limitations as defined by human factors engineering principles
Dismounted, foot-mobile soldiers currently use a wide variety of wearable technologies, e.g., GPS (global positioning system) /PNT (position, navigation, timing), night vision goggles (NVGs), rangefinders, radios, other Nett Warrior items, etc. These wearable technologies, i.e., electronic systems carried and used by soldiers, sailors, airmen and marines, constitute the individual soldier’s technological ecosystem
