In this video, a fruit fly steers a small robot through an obstacle course. The researchers at ETH Zurich's Institute of Robotics and Intelligent Systems glued a fly down in front of an array of LEDs and flashed patterns that tricked it into thinking it was flying. Data from a computer vision system trained on the fly's wings was then translated into commands for the mobile robot in the obstacle course. The robot was outfitted with sensors that triggered the appropriate light patterns on the LEDs. The whole shebang is called The Cyborg Fly. From IEEE Spectrum:
"As autonomous robots get smaller, their size and speed approach that of the biological counterparts from which they are often inspired," they write in the paper, adding that their technique could "be relevant to the tracking of micro and nano robots, where high relative velocities make them hard to folow and where robust visual position feedback is crucial for sensing and control..."
The Cyborg Fly is not the only "flight simulator" for bugs, and other research groups have used insects to control robots. But still, the ETH project stands out because of its high-speed vision component. This system could be useful not only for biology research, to study insect flight and track fast movements of appendages or the body, but also for industrial applications -- for monitoring a production line or controlling fast manipulators, for example.
In the current acquisition binge around artificial intelligence, tech behemoths with deep pockets lead the way, including Google, Apple, Facebook, Amazon, Intel, Microsoft, Twitter, and Salesforce. The only one with a limited consumer-facing presence is social monitoring firm Meltwater.
In 2008, Telstra Chief Scientist Geoff Huston wrote an informative and important retrospective on the shifts in internet technology since 1998; now, ten years later, he's written another one, tracing the remarkable shifts (and weirdly unbudgeable technological icebergs) in the past decade's worth of internet changes, advances and retreats.
Improved super-thin solar panels and nuclear fission are all in development to handle the massive logistical problems of meeting power needs in space. Fraser Cain takes viewers through the newest developments, including NASA’s new Kilopower Reactor.
Summer’s here, which brings not only warmer weather but also the unsettling realization that the year is more than halfway over. So, for those who weren’t as productive as they would have liked during the first half of 2018, we’ve rounded up 5 skill course bundles you can start learning today to help you finish […]
It’s good to be proactive, but when it comes to preparing for an emergency situation, one of the most important items you can pack is a flashlight. After all, whatever else you include in your kit won’t be of much use if you can’t see what you’re doing. The Viper 1000-Lumen Tactical Flashlights not only […]
Chances are you took a handful of language classes in high school, and aside from a smattering of conjugations and vocabulary words, the only things you likely remember are the dry, rehearsed sentences that did little to make you speak like a true native. If you’re still hoping to learn a new language but want […]
