An untethered model that is fully wireless and autonomous, weighing less than 1 gram and carrying its battery and all electronic components on its back. Credit: EPFL Researchers at EPFL have developed an ultra-light robotic insect that uses its soft artificial muscles to move at 3 cm per second across different types of terrain. It can be folded or crushed and yet continue to move. Imagine swarms of robotic insects moving around us as they perform various tasks. It might sound like science fiction, but it’s actually more plausible than you might think. Researchers at EPFL’s School of Engineering have developed a soft robotic insect, propelled at 3 cm per second by artificial muscles. The team developed two versions of…

A conceptual hypersonic aircraft, powered by an oblique detonation wave engine, is pictured. Background image credit: NASA. Aircraft and composite image credit: Daniel Rosato, UCF. The UCF-developed propulsion system could allow for flight speeds of Mach 6 to 17 (more than 4,600 to 13,000 miles per hour) and would have applications in air and space travel. University of Central Florida researchers are building on their technology that could pave the way for hypersonic flight, such as travel from New York to Los Angeles in under 30 minutes. In their latest research published recently in the journal Proceedings of the National Academy of Sciences, the researchers discovered a way to stabilize the detonation needed for hypersonic propulsion by creating a special…
