postheadericon Robot fish get upgraded, keep schooling real-life counterparts

Okay, so they still look like Depression-era bath toys, but Maurizio Porfiri’s robot fish have come a long way from the coconut-and-tin-foil look they were sporting last summer. In an attempt to further “close the loop” between robotics and nature, Porfiri has continued to tinker with the little leaders by incorporating diving and surfacing into their aquatic repertoire, and it seems to be working: real fish have shown interaction patterns including tracking, gathering, and following in the presence of the pesci-bots. Now if they could just do the same with the the feral ferret living in our bedroom walls…

postheadericon Water-propelled jetpack is no dream, can be yours for $99,500 this March (video)

It’s taken a long time since that 2005 patent was filed for, but Raymond Li is now finally ready to bring his water-propelled jetpack to the money-spending world. Nailing down a March 2011 launch date and a price of $99,500 hasn’t been easy for the inventor, who says his efforts to procure capital and prototyping quotations were mostly met with incredulity — “almost everyone thought I was crazy.” His JetLev personal transporter relies on an engine and fuel tank (which remain on the water’s surface) to pump H20 into a backpack that then shoots out streams of the drinkable stuff to keep your airborne. Top speed is 22MPH, max height is nearly 33 feet, and the fun factor is somewhere off the scale, whether you’re talking metric or imperial. Levitate past the break for a video demonstration.

[Thanks, Suraj]

postheadericon China builds a jet-propelled water cannon, just because it can (video)

Just what does $456,000 buy you these days? Well, if you happen to run the fire department of China’s Luoyang City, the answer is a jet-propelled water cannon capable of spraying four tons of water per minute. That pretty much qualifies it for a “terminal velocity” badge, as the water is said to move at such speed as to choke fires from the oxygen surrounding them. Maximum range for this blaze blaster is 120 meters (nearly 400 feet), though you’ll need to only move a fraction of that distance to click past the break and watch the awesome video of it in action.

postheadericon Twin camera concept floats in water, unites sea and sky

Taking an underwater self-portrait isn’t the easiest thing in the world — even if you’re fond of robot DIY — but this concept camera won a Red Dot award for capturing more than typically meets the eye. The UNDERABOVE floats like a buoy thanks to a pair of watertight ballast compartments, takes images with twin cameras above and below, then stitches the result into a turquoise vertical panorama viewable on the inbuilt LCD screen. If and when this device actually gets produced (and gains some serious image stabilization) the worlds of fish and man will never be the same.
