Tiny flying insect drones now a reality: See the video of controlled flightSubmitted by legalizeliberty on Fri, 05/10/2013 - 10:25
(NaturalNews) It's been more than a decade in the making, but now Harvard University researchers have developed a tiny flying drone that is barely larger than a quarter.
Robotics researchers at the Ivy League school have achieved a first, reports Forbes: the creation of robotic insects that are capable of flight. A paper detailing their work was recently published in the journal Science. Here's an abstract of the research:
Flies are among the most agile flying creatures on Earth. To mimic this aerial prowess in a similarly sized robot requires tiny, high-efficiency mechanical components that pose miniaturization challenges governed by force-scaling laws, suggesting unconventional solutions for propulsion, actuation, and manufacturing. To this end, we developed high-power-density piezoelectric flight muscles and a manufacturing methodology capable of rapidly prototyping articulated, flexure-based sub-millimeter mechanisms.
We built an 80-milligram, insect-scale, flapping-wing robot modeled loosely on the morphology of flies. Using a modular approach to flight control that relies on limited information about the robot's dynamics, we demonstrated tethered but unconstrained stable hovering and basic controlled flight maneuvers. The result validates a sufficient suite of innovations for achieving artificial, insect-like flight.
