 | 60 Years Ago: First American in space
In 1961, the United States and the Soviet Union found themselves in a race to put the first human being into space. The Soviets won the race in April 1961, but on May 5, 1961, Alan B. Shepard became the first American in space during a suborbital flight aboard his Mercury capsule named Freedom 7. Three weeks later, President John F. Kennedy committed the United States to achieving a lunar landing before the end of the decade.

 | Enhanced UR10e cobot handles 25% more payload
Universal Robots has just released a new, enhanced version of its bestselling cobot, the UR10e, with 25% more payload capacity. That means this versatile unit can now handle 27.55 lb. The increased payload is a response to customers needing to move heavier items in applications like palletizing using the UR10e. Better yet, the robot's price is staying the same.

 | Researchers create world's most power-efficient high-speed ADC microchip
To meet soaring demand for lightning-quick mobile technology, each year tech giants create faster, more powerful devices with longer-lasting battery power than previous models. To do that, they need better and better high-speed analog-to-digital converter (ADC) microchips. A new chip developed by researchers at BYU has the highest power efficiency currently available globally -- a record it holds by a substantial margin. In this article, the researchers explain how they did it.

 | Automation: ECONOmaster drilling units -- affordable, flexible, get the job done
Suhner's ECONOmaster® is a low-cost, high-output automated drilling unit that puts holes in light metal, composite, thermoplastic, and even wood substrates at high speed with excellent accuracy. It features low power and air consumption. On a recent project for Mid-State Engineering, Suhner custom ECONOmaster drill units -- featuring selectable drill heads that can be used in combination or individually -- were used to automatically drill holes into fiberglass panels for truck trailer bodies.

 | Servo press vs. hydraulic press: Which is best for automotive stamping?
The subtle shift made by automotive metal stampers from mechanical to hydraulic to servo press may be largely imperceptible, but it is there. Stampers are attracted to the speed and versatility of the servo press, but the hydraulic press isn't going anywhere. It remains a budget-conscious stamper's top pick -- and possibly the only solution for jobs that require high-force demand early in the stroke. So how real is the stamping shift? And which technology is best suited for metal forming in the automotive industry?

 | Voice coil stages and actuators for precise motion
Because of their small dimensions, voice coil motors are often integrated in compact stages, actuators, and fast tip/tilt mirror platforms. These devices are driven by an electromagnetic motor consisting of a moving coil winding and a fixed magnet (the opposite is also possible). By precisely controlling the electric current in the coil, the magnetic force (Lorenz force) -- and thus, acceleration, velocity, and position -- can be varied very accurately.

 | Sealing fasteners may optimize your designs
Highly specialized sealing fasteners include sealing screws, sealing nuts, sealing bolts, and sealing washers. Unlike ordinary fasteners, sealing fasteners are configured with a rubber O-ring (or a rubber element) that, when squeezed, permanently seals out a wide range of contaminants from entering and damaging equipment while preventing leakage of toxins into the environment. ZAGO sealing fasteners are designed to withstand harsh weather and extreme temperatures and are vibration and pressure resistant.

 | Compact, low-noise gearboxes for high loads
With the GP56-N series, the Nanotec product line now also includes low-noise planetary gearboxes for brushless DC motors and stepper motors with flange size 56 and 60 mm. They are ideally suited for applications in medical devices and building automation. The helical toothing allows the teeth to mesh gradually, which results in a smoother transmission of forces so that vibrations and noise are reduced. Planetary gears and the ring gear consist of a high-quality, low-wear plastic, making the new gearboxes quieter than conventional, straight-geared metal gearboxes. Available in one- and two-stage versions in nine different reductions and varying output torques.

 | Gearless speed reducers with traction drive tech
Stock Drive Products/Sterling Instrument (SDP/SI) has introduced new speed reducers with traction drive technology. Featuring a gearless drive, these speed reducers are highly efficient and feature only six moving parts. They use engineered traction fluid to cool and lubricate, and they generate less heat than conventional drives. Years of development and testing have been invested in this new technology, resulting in a product featuring infinite ratios up to a ratio of 5:1, dramatic reduction of motor torque ripple, low vibration and noise level, and significantly less maintenance than a conventional gearbox.

 | NASA working on solid-state battery using 'holey graphene'
A NASA project called SABERS is researching how to create a safer battery by using brand-new materials and novel construction methods. The goal is to create a battery that has significantly higher energy than lithium-ion batteries. This battery also would not lose capacity over time, catch fire, or endanger passengers if something goes wrong.
