Do androids dream of electric sashimi?
University of Virginia engineers and Harvard biologists built a robotic fish based on the high-performance swimming of tuna. Above, a visualization of the robot's motion data. Eventually, the Tunabot could be outfitted with a variety of sensors and wireless communication. From UVAToday
The aim of (mechanical engineering professor Hilary) Bart-Smith’s project is to better understand the physics of fish propulsion – research that could eventually inform development of the next generation of underwater vehicles, driven by fish-like systems better than propellers.
Underwater robots also are useful in a range of applications, such as defense, marine resources exploration, infrastructure inspection and recreation...
The eyeless, finless replica fish is roughly 10 inches long; the biological equivalent can get up to seven feet long. A fishing line tether keeps the robot steady, while a green laser light cuts across the midline of the plastic fish. The laser measures the fluid motion shed by the robot with each sweep of its fabricated tail. As the current of water in the flow tank speeds up, the Tunabot’s tail and whole body move in a rapid bending pattern, similar to the way a live yellowfin tuna swims.

“Right now, most Americans are in a perpetual police lineup because they got a driver’s license,” says Clare Garvie, a Washington DC privacy expert. In this New York Times video, Garvie says that driver license photos are scanned and translated into a “face print” that face recognition software can use to compare photos and find […]
Evan from Fight for the Future writes, "More than 30 civil rights organizations, including Fight for the Future, Color of Change, National Immigration Law Center, and CAIR, have signed an open letter calling for elected officials to investigate Amazon Ring’s business practices and put an end to all Amazon-police surveillance partnerships. This is the first […]
I'm 100% in favor of pro-competitive regulation of Big Tech, and that is because I'm 100% in favor of pro-competitive regulation of all our hyper-concentrated, monopolistic industries.
There’s overwhelming support for clean energy, and the planet is giving us more reasons to invest in renewable power sources with every passing year. Even in the most inhospitable areas, wind and solar can provide a good chunk of our power, if not all of it. So why aren’t we all taking advantage of it? […]
Hey, we love Netflix and Hulu, but let’s face it: The whole setup doesn’t exactly encourage active viewing. For all the binge-watching we’ve done, it’s tough to expand our horizons or learn anything new – except for how many episodes of “The Office” it takes to make us fall asleep. It was only a matter […]
