Army’s 'Wingman' program developing armed robo Humvees and other vehicles
Army engineers aim to qualify an autonomous combat vehicle on a gunnery range in the coming months as part of a new program they say is the first step toward weaponized robotics. Under the "Wingman" Joint Capability Technology Demonstration program, engineers have already been able to autonomously pilot a specially configured Humvee and hit targets with its on-board 7.62-mm weapon system.

How a powerful LED-based train headlight was optimized for energy savings
Researchers in Taiwan have designed a new LED-based train headlight that uses one-tenth of the energy required for headlights using conventional light sources. To create a high-efficiency train headlight, the design challenge came in the form of how to combine the small outputs of multiple high-efficiency LEDs into a larger circular output to create a beam large enough to use as a train headlight.

Can shark skin help planes fly better?
A team of evolutionary biologists and engineers at Harvard University has shed light on a decades-old mystery about shark skin and, in the process, demonstrated a new, bioinspired structure that could improve the aerodynamic performance of planes, wind turbines, drones, and cars. For inspiration, they turned to the shortfin mako, the fastest shark in the world.

How a NASA engineer created the modern airplane wing
Once dubbed "the man who could see air," NASA engineer Richard T. Whitcomb used a combination of visualization and intuition to revolutionize modern aviation -- by turning the shape of the airplane wing on its head. Today, nearly every commercial airplane bears the marks of Whitcomb’s several innovations.

Advanced Motor Tech:
Precision motion for X-ray optics

Despite their potential danger, X-rays are one of the most powerful instruments and resources utilized in medical diagnostics to help medical professionals restore health by identifying the correct prognosis. When it comes to achieving the best imaging with the lowest X-ray exposure, lenses made by Optec are almost inevitably involved. Their aperture, focus, filters, and zoom are moved by FAULHABER motors.

Tribology: How specialized coatings can make mechanical parts harder for extreme industrial applications
Although bearings, gears, rollers, and other precision components are generally made of hardened steel or metal alloys, those used in high-load applications still can fail due to excessive wear, surface fatigue, pitting, galling, and corrosion. To address this problem, product engineers and component manufacturers often turn to specialized PVD (physical vapor deposition) coatings that can further harden the surface of these parts. Oerlikon Balzers provides solid solutions.

Introducing the smallest wave springs on the market

Smalley has expanded the Crest-to-Crest® Wave Spring Series. Smalley's popular C (imperial) and CM (metric) Series have been expanded; standard sizes are now available from stock down to .188 in. and 5 mm in diameter. Smalley Wave Springs can replace conventional coil springs while occupying only half the space and providing the same force and deflection.

Choosing between brush and brushless DC motors: What are the tradeoffs?
Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application.

Image - How hexapods advance production processes
How hexapods advance production processes
Hexapods, six-legged parallel-kinematic machines, are quickly gaining ground in a broad range of industrial automation applications after "learning" how to directly communicate with PLC or CNC controllers via fieldbus interfaces. They are used in such varied processes as aligning the smallest optical components in silicon photonics to positioning entire body parts for automotive production, and the intrinsic hexapod features contribute to a wealth of new possibilities in robotics. PI (Physik Instrumente) gives a comprehensive rundown on the state-of-the-art in hexapod tech.

Air gun with variable flow from the squeeze of a trigger
EXAIR’s new VariBlast® Compact Safety Air Guns are a small and lightweight cast aluminum air gun capable of handling tough jobs. Because of the engineered variable flow trigger, they are able to produce light, medium, or heavy force upon a target simply by pulling the trigger. This comfortable and ergonomic air gun has two 1/4 NPT air inlets and a storage hanger for convenience. Air consumption of the VariBlast Compact air gun is only 10-17.5 SCFM, depending on the nozzle installed, which is among EXAIR’s most efficient air guns. It is capable of producing up to 1 lb of force, making it a great choice for light- to medium-duty applications. Extensions up to 72 in. long available.

Image - Smallest capacitive touch LED sensor display
Smallest capacitive touch LED sensor display
Visual Communications Company (VCC) recently launched the CSM Series surface-mount capacitive touch LED sensor, which boasts the smallest footprint in the industry. These displays are unique because they measure only 15.0 mm x 15.0 mm x 3.2 mm and can be surface mounted or even reverse mounted to save additional space. The compact, high-output LED sensor displays can be used in a wide range of applications, including: medical devices, home automation and mobile communication devices, as well as portable instruments. Available in green, yellow, red, blue, and white, these touch sensor displays provide streamlined manufacturing and enhanced product life cycle over a mechanical on/off switch because there are no mechanical components to wear down or break.

USAF selects Garmin D2 Charlie aviator watch for pilots

The United States Air Force has picked Garmin's D2 Charlie aviator watch to be used by the pilots of the Lockheed U-2 aircraft. The high-sensitivity WAAS GPS-enabled D2 Charlie aviator incorporates global navigation capability, rich and colorful moving maps, and more, providing pilots in the USAF with an exclusive, back-up navigation timepiece in the cockpit. Most of us aren't pilots, but we can imagine flying a little higher in everyday life with wrist tech like this, which also offers weather and radar; a complete feature set of sports/training, fitness, and outdoor navigation tools; and phone, text, and message screening options.
