Forensic scientists are trying to understand what tears and distortions in the fabric around a stab wound can say about the knife type, angle of attack, and stabbing technique that caused the wound. But the patterns have been difficult to work out, partly because researchers have had to do most of their laboratory experiments by hand, manually stabbing different fabric swatches. But inconsistencies and human error are unavoidable. So a team of forensic scientists and engineers invented a stabbing machine to help standardize this type of research.
Atmospheric Dive Suits (ADS) are required for dives below three hundred feet. The ADS is a human-shaped hard shell enclosing diver so they can breathe air at normal pressure. ADS become more sophisticated in some ways over the last century, but they still have primitive lobster-like claws called prehensors rather than hands.
Looking back, Google’s emergence as a robotics powerhouse seems obvious—and inevitable. First came the scattered hires of roboticists and the release of self-driving cars into Bay Area traffic. Then, the search giant reportedly bought two humanoid HUBO robots from South Korean university KAIST. But it wasn’t until December’srevelation that Google had acquired eight robotics companies—including Boston Dynamics, maker of BigDog, WildCat and a stableof other astonishing Pentagon-funded bots—that it became clear: Google means to build robots.
We've seen robots with wheels, robots with legs, and even robots with whegs. We've seen snakebots that use a creepy combination of undulation and grip to shimmy and swim. Now one research team has come up an innovative new robot with yet another way of getting around. They've made a plastic sphere with a mechanism inside to propel it like a hamster in a ball.
Our 35 centimeter long robotic elephant trunk has five segments, each made of a silicone membrane with an embedded metal spring that acts like an exoskeleton. The segments are filled with dry coffee grounds and each is vacuum-controlled separately. When coffee grounds are loosely packed, they're in a liquid-like state. When they're vacuum-packed, they transition into a solid-like state.
Though he was destined for manual labour, countless days spent toiling in the factory could not dampen this robot's dream. He was built to examine how objects reflect light, but he never failed to see the beauty in the patterns of light bouncing off a mundane object, say a child's backpack. He always wanted to be an artist, he just needed the chance!
