John W.M. Bush, an associate professor in mathematics at MIT, has studied the underlying hydrodynamics of the seemingly miraculous feat of walking on water (as some insects do). By using mathematics, high-speed photography, and flow visualization techniques, he discovered something short of a miracle: The insects use one set of legs like oars, sculling their way across the water's surface. A full report is in the August 7 issue of Nature Magazine.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
