Become a robot programmer in only 87 minutes!
Learning how to set up and program a collaborative robot -- or cobot -- no longer depends on real-life access to a robot or a training class. Now everybody with a desire to learn the concepts of cobots can log in to the Universal Robots Academy and get the introduction necessary to master basic programming skills. Become a master of the cobots! (That's a pretty sweet title.)

Hot stuff: New system draws power from daily temperature swings
Thermoelectric devices, which can generate power when one side of the device is a different temperature from the other, have been the subject of much research in recent years. Now, a team at MIT has come up with a novel way to convert temperature fluctuations into electrical power. Instead of requiring two different temperature inputs at the same time, the new system takes advantage of the swings in ambient temperature that occur during the day-night cycle.

Army hydrogen fuel-cell Chevy pickup takes on training in Hawaii
Soldiers from the 25th Infantry Division put the Army's ZH2 fuel-cell electric vehicle through the rigors of operating in jungle terrain during a training exercise at Schofield Barracks in Hawaii in late January. The aim was to evaluate the Chevrolet Colorado ZH2's operational effectiveness during multiple reconnaissance missions, putting General Motors' fuel-cell and off-road vehicle technology investments and commercial off-the-shelf products to the test.

Image - Engineering mystery: What's that white crack in my bearing?
Engineering mystery: What's that white crack in my bearing?
Metal bearing failure due to rolling contact fatigue is generally a rare occurrence, but it does happen. A characteristic feature of many premature failures is the extensive subsurface crack networks that have a “white etching appearance,” referred to commonly as white etching cracks. Bearing specialists at SKF take a deep look into this phenomenon in an attempt to determine if the white cracking causes failures or is simply a symptom of a bigger problem.

Tests show strength of Tri-Mack’s overmolded thermoplastic composite hybrid bond
Tri-Mack Plastics Manufacturing is sharing the results of a recently completed test that demonstrates the bond strength of a hybrid panel that combines injection overmolding for design flexibility with unidirectional thermoplastic composites for strength and stiffness. The data helps validate the performance of hybrid composites, which are of particular interest in aerospace and other industries where the goals of lighter weight and lower cost are driving material innovation.

It's all about precision: Photo etching specialty stainless steels and more
Tech-Etch uses the photo etching process to produce component parts for industrial, aerospace, and medical applications. Precision thin metal parts can be made from specialty stainless steel alloys like MP35N used in implanted medical devices, Elgiloy used in replacement heart valves, and 716 and 420 alloys used for surgical blades. Other etched materials include Inconel, Hastelloy, titanium, niobium, nitinol, and magnesium, which is gaining interest as a bioresorbable surgical implant material. Parts range in thickness from .0005 in. and up. While providing quick turnaround and low tooling costs, photo etching produces burr-free parts with intricate and complex shapes. Designs can be proved in preproduction quantities without having to commit to expensive tooling. Forming, heat treating, plating, laminating, and assembly are available in house.

Sealing tapes and die-cut gaskets approved for F-16
GORE SKYFLEX Aerospace Materials products have been approved for use on F-16 wing access panels. These materials effectively seal panels and protect against mechanical forces and harsh environments that can damage aircraft structures, such as vibration, corrosion, high temperatures, aggressive fluids, UV radiation, and other environmental hazards that tend to break down and weaken traditional materials. Unlike traditional two-component sealants, the materials are lightweight and non-curing, and they simplify the process by reducing installation steps. They are available in a variety of form-in-place (FIP) tapes and die-cut gaskets in various sizes.

Jet-powered UAV tests flapless blown-air control system
When we think of things that fly, they usually have wings with some kind of moving parts. Even Superman had to thrust his arms forward. But engineers at BAE Systems, along with a team of researchers at the University of Manchester in the U.K., have built and flown a jet-powered UAV that is trying out a new type of aircraft control. They call it "flapless flight."

Electric current flow steered with spinning light
Light can generate an electrical current in semiconductor materials. This is how solar cells generate electricity from sunlight and how smart phone cameras can take photographs. To collect the generated electrical current, called photocurrent, an electric voltage is needed to force the current to flow in only one direction. In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage.
