50 Years Ago: Apollo 11 prep includes Lunar Lander, flight hardware tests With the successful completion in March 1969 of the Apollo 9 mission that tested the Lunar Module in Earth orbit, NASA's confidence rose that President John F. Kennedy's goal of landing a man on the Moon and returning him safely to Earth before the end of the decade was achievable. But March and April were also busy months prepping for Apollo 11.

World's largest airplane (and space launcher) completes first flight It's wider than a football field is long, and it really flies! Stratolaunch Systems, the space company started by Microsoft co-founder Paul Allen, reached a major milestone on Saturday, April 13, when its dual-fuselage main carrier vehicle, called Stratolaunch, flew for 2.5 hours over the Mojave Desert on its maiden flight. The giant plane will one day launch rocket-propelled space payloads from its center span while in the air.

Material's color, thermal properties tuned separately White things reflect heat, and dark things absorb it. Isn't that how it goes? Well not anymore. MIT engineers have figured out a way to tailor the color and heat properties, independently, of a strong polymer material. They designed a thin black film to reflect heat and stay cool and also made films of other colors that reflect or absorb infrared radiation regardless of the way they respond to visible light. So many possibilities!

Chairless exoskeleton solves long-standing problem The Chairless Chair is a new innovation for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. Operating a switch on the strap turns the flexible construct into a stable seat. Two small FAULHABER DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.

Top Product: Cross roller ring can swing the loads Because it has orthogonally arranged cylindrical rollers, the cross roller ring from THK is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90-deg V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including radial, axial, and moment loads. This component is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing machines. Available in several rotation configurations including inner/outer ring, inner ring only, and outer ring only. And now a new micro cross roller ring is perfect to handle smaller applications. Learn more about THK cross roller rings. Learn about the new Micro Cross Roller Ring RAU.

Largest autonomous mobile robot can lift 1 metric ton At the Automate 2019 Show and Conference, Mobile Industrial Robots launched the MiR1000, the company's largest autonomous mobile robot (AMR). This mobile platform can automatically pick up, transport, and deliver pallets and other heavy loads up to 1,000 kg (2,200 lb) through dynamic environments. Like the MiR500 introduced in 2018, the MiR1000 is a collaborative, safe, and flexible alternative to potentially dangerous and expensive forklifts on the factory floor. MiR also released another industry first -- artificial intelligence (AI) capabilities across all of its AMRs for improved navigation.
