Drone technology is quickly evolving –no longer just for military use, these flying robots now have a place within commercial enterprise. Also known as unmanned aerial vehicles, drones today have practical applications, like delivering packages for Amazon or allowing realtors to take aerial video to show off a sale property. (more…)
A two-armed robot named Tarzan, swinging along elevated cables, could allow farmers to monitor fields continuously at lower cost while avoiding interference with plants.
“Swinging – or brachiation – is an energy-efficient way to travel because gravity is doing most of the work,” said Ai-Ping Hu, a senior research engineer at the Georgia Tech Research Institute (GTRI). The lightweight robot has aluminum arms and 3D-printed hands with sensors. The eight-pound robot swings back and forth with one hand on the cable, gaining momentum until its second hand detects the cable overhead and grips it. This swinging motion replicates a gibbon’s movement along a tree limb or vine. (more…)
Berkeley Lab Researchers Demonstrate Advance in Controlling Nano-scale Vibrations at 10 GHz
An advance has been achieved towards next generation ultrasonic imaging with potentially 1,000 times higher resolution than today’s medical ultrasounds. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated a technique for producing, detecting and controlling ultrahigh frequency sound waves at the nanometer scale.
