A 3D-Printed Nod to Lady Liberty

Editors Note: Over the course of this week, Machine Design will be sharing a series of articles addressing the development and distribution of the COVID-19 vaccine—and the obstacles surmounted along the way. Be sure to check out the other installments below: At a Glance: A group of engineers collaborate to design and produce a respirator to help offset a shortage of personal protective equipment during the pandemic. The particulate filtering facepiece respirator, also known as the OSR-M1, rivals the industry’s…

Squid-inspired robot swims with nature’s most efficient marine animals

Robot. 6, eabd2971 (2021) Scientists at the University of Southampton and University of Edinburgh have developed a flexible underwater robot that can propel itself through water in the same style as nature’s most efficient swimmer—the Aurelia aurita jellyfish. The findings, published in Science Robotics, demonstrate that the new underwater robot can swim as quickly and efficiently as the squid and jellyfish which inspired its design, potentially unlocking new possibilities for…

Practical Predictive Maintenance for Machines

At a glance: A software-powered simulation for assembly behavior can compensate for the gap in automation by building intuition in the safety of a high-fidelity digital twin. The best way to align a screw is a thumb and finger because human fingers have mechanical properties that many engineers spend their careers trying to replicate. Software-defined manufacturing can fundamentally transform how products are made. Thanks to advancements in robotics, software and computer vision most stages of manufacturing today are highly automated—from the…

Fast TRACK Career – University of Missouri College of Engineering

Leah Albietz with her 1993 Corvette she built with her father. Leah Albietz is on the fast track, whether in or out of her race car. “My dad owns a racing engine shop in St. Louis, and he has always been around the drag racing scene there,” Albietz said. “I’ve grown up going to the racetrack and helped him build engines whenever I could.” Albietz, BS ME ’20, from Wentzville, MO, went beyond just engine building. At age 13, she…

How do you know where a drone is flying without a GPS signal?

Credit: Aalto University In Jouko Kinnari’s doctoral dissertation, the location of a drone can be determined using map data and sensors. When Jouko Kinnari started his doctoral dissertation while on Saab’s payroll in January 2019, the concrete research question was not yet clear. After some discussions and preliminary research, the localisation of unmanned flights was selected as the topic.…

Orient Electric Fans Review – Summer Breeze Pro, Twister and Rapid Air

Whenever we speak about fans, there is always a certain brand whose picture we paint in our head and start speaking about them, referencing that brand. One such brand that has laid an impression on the Indian customer base is Orient Electric. A product of CK Birla Group, with a worldwide presence, many awards, and accolades in its bucket and world-class products, Orient Electric has evolved as a trusted brand in the Global Fan Industry. Recently, Orient Electric has launched…

Light-controlled Higgs modes found in superconductors; potential sensor, computing uses — ScienceDaily

Even if you weren’t a physics major, you’ve probably heard something about the Higgs boson. There was the title of a 1993 book by Nobel laureate Leon Lederman that dubbed the Higgs “The God Particle.” There was the search for the Higgs particle that launched after 2009’s first collisions inside the Large Hadron Collider in Europe. There was the 2013 announcement that Peter Higgs and Francois Englert won the Nobel Prize in Physics for independently theorizing in 1964 that a…

The design could be a quieter version of velcro with uses ranging from diapers to robotics — ScienceDaily

A Velcro-like fastener with a microscopic design that looks like tiny mushrooms could mean advances for everyday consumers and scientific fields like robotics. In Biointerphases, published by AIP Publishing, researchers from Wageningen University in the Netherlands show how the design can use softer materials and still be strong enough to work. Probabilistic fasteners work, because they are designed with a tiny pattern on one surface that interlocks with features on the other surface. Currently available fasteners, like Velcro and 3M,…

Challenges of Automated Assembly | Machine Design

A product’s design determines its features, materials, performance, time to market and costs. Its quality, however, depends on the quality of the processes used to develop and make it. This doesn’t mean good designs only come from healthy design processes, but the odds of good results are surely higher if the processes are healthy. So, how healthy are your product development processes? Check-up List One way to assess a company’s design processes is to have those involved in those processes…
