What Is Industry 4.0, Anyway?
The four industrial revolutions: (1) Mechanization through water and steam power. (2) Mass production and assembly lines powered by electricity. (3) Computerization and automation. (4) Smart factories and cyber-physical systems. If you’ve been to a trade show or read an op-ed on manufacturing in the past few years, chances are you’ve seen the terms ‘Industry
Cobots: the Rise of the Collaborative Robot (Cobot) – What You Need to Know
As we move to the realization of more Industry 4.0 implementations as part of an ongoing industrial transformation journey, the use of collaborative robots (cobots), which are designed to work alongside people in, among others manufacturing , warehousing, logistics and healthcare, is expected to grow at astonishing rates in the next few years. The idea
The Car of Tomorrow: Under the Hood
Autonomous vehicles get all the attention, but in the next several years, the experience of driving will change in many other ways. “Things are moving really fast,” says Anna Stefanopoulou, a professor of mechanical engineering at the University of Michigan. “Automotive technology hasn’t advanced this quickly since the era of the Model T.” At the
High Density Reactive Composite Powders
Abstract . Materials capable of armor penetration and prompt chemical energy release are desired for future weapon systems in order to better couple the kinetic energy of a projectile to its target. High-density metals used today such as tungsten are slow to react, and do not generate as much chemical energy as lower density materials,
Russia Will Not Mass-Produce T-14 Armata Main Battle Tank
Given the high price tag of Russia’s new main battle tank, the Russian military is looking for cheaper alternatives. Russia will not mass-produce its new third-generation T-14 Armata main battle tank (MBT) as it is too costly, Deputy Prime Minister Yuri Borisov told Russian media on July 30. Instead, the Russian military will continue to
U.S. Must Hustle On Hypersonics, EW, AI
China is besting the United States in key military technologies like hypersonic missiles and electronic warfare, Gen. Paul Selva, vice-chairman of the Joint Chiefs said today. We can still catch up, he predicted. What about Artificial Intelligence? That’s too close to call, said former deputy Defense Secretary Bob Work, so we’d better get a move
Bringing Drones into a Smart City Network
San Diego is in the midst of a tech convergence. It is working to build what it calls the nation’s largest smart city network, and it also was selected for the U.S. Department of Transportation”s UAS Integration Pilot Program. The city plans to bring these two efforts together, coordinating unmanned aerial systems with the smart
Nevada Launches Drone Safety Research Center
Nevada to establish Drone Center of Excellence for Public Safety. Nevada is no stranger to drones. The state is one of the Federal Aviation Administration”s original national test sites for unmanned aerial systems technology, and has produced research into drone traffic management systems. The city of Reno was selected for FAA’s Drone Integration Pilot Program,
America Needs New Weapons
Today, high-energy laser and high-power microwave systems—or “ directed energy ” weapons, which use focused electromagnetic energy—have been shown to work and could combat a variety of emerging threats, but more investment is needed to bring them into the hands of our warfighters more quickly to protect the American people. One might imagine that using
Fiber Lasers Mean Ray Guns Are Coming
The U.S. Navy’s most advanced laser weapon looks like a pricey amateur telescope. As it emerges from a chassis high on the USS Ponce to look out onto the daytime sky above the Persian Gulf, its operator sits in a darkened room elsewhere on the ship holding what looks like a game controller. The screen
Hydrazide Salts of Di‐Picric Acid as Dense and Insensitive Energetic Materials
Abstract. Energetic dipicrate hydrazide salts were synthesized by combining picric acid (PA) as anion and carbohydrazide and oxalyldihydrazide as cations in stoichiometric amounts (2 : 1 mol ratio). The structures of 2,2′‐carbonyldi(hydrazin‐1‐ium) bispicrate (1) and 2,2′‐(1,2‐dioxoethane‐1,2‐diyl)di(hydrazin‐1‐ium) bispicrate (2) were investigated by single‐crystal X‐ray diffraction analysis, illustrate that both crystals of 1 and 2 belong to the
