Cutting Edge

A robot fish developed at the U.K.'s University of Bath features a unique method of propulsion--a single fin rippling along its belly like a wave. Bath engineers say Gymnobot might inspire lighter, more efficient robotic submersibles.

Recent robot fish, such as MIT's low-cost polymer fish, have flexible bodies, but Gymnobot is rigid save for a long undulating fin powered by twin crankshafts inside its body.

The design is a nod to freshwater knifefish, which can move forward and backward, and hover, by rippling an elongated ventral fin. The skin of the fin covers hundreds of fin rays … Read more

Aldebaran Robotics is showcasing the skills of its pint-size humanoid robot Nao ahead of its planned mass market release in about a year.

Nao is definitely one of the coolest humanoids around that stands a chance of making it into households as a real product. Aldebaran envisions it as "an autonomous family companion."

Fully programmable, the 23-inch bot boasts 25 degrees of freedom, affording it an impressive range of motion. Check it out in Nao's new promo vid after the jump.

Nao can grasp objects with its prehensile hands; process image and sound data; and navigate its environment using its sonars. Multimedia features include high-fi speakers, microphones, and CMOS digital cameras.

The biped runs on an x86 AMD Geocode 500 MHz CPU, 256MB SDRAM, 2GB flash memory, and lithium polymer batteries that last about 90 minutes per charge.

With striking similarities to Sony's discontinued Qrio humanoid, you'd think Nao was made in Japan. Pas du tout. Aldebaran is based in Paris, though Nao can only speak English. … Read more

Perhaps you are skeptical about the notion that computers will, one day, actually control us.

Perhaps you might imagine yourself to be a little dependent on your digital friend but not to the degree that it tells you what to do.

Perhaps, however, you have never stayed at the Hotel Monte Mulini on Croatia's Adriatic Coast. Please allow me to explain.

I am currently in Rovinj, Croatia, home of the Weekend Media Festival. The festival has speakers from companies such as Google, MTV, and Nokia and, well, there was this one speech Saturday titled, "Why advertise when you … Read more

Panasonic has created a robotic bed that can transform into a wheelchair, allowing the elderly or people with disabilities to get up without assistance.

Users can remain in the bed while it turns into a wheelchair. Half of the mattress rises and half lowers while a motorized unit beneath it automatically slides out from the bed.

While in chair mode, the robot can detect people and obstacles and help users avoid collisions, according to Panasonic.

A controller allows for driving and returning to the bed.

The mattress can also help people turn over in bed to prevent bedsores.

The bed'… Read more

After two months of checkout and calibration, NASA's $504 million Lunar Reconnaissance Orbiter was maneuvered into a circular 31-mile-high mapping orbit Tuesday, and scientists said Thursday the spacecraft's instruments are delivering intriguing clues about the possible presence of water ice.

"The moon is starting to reveal her secrets, but some of those secrets are tantalizingly complex," said Michael Wargo, NASA's chief lunar scientist.

Scientists expected the spacecraft to find signs of hydrogen--an indicator of possible water ice deposits--in permanently shadowed craters near the moon's south pole. Ice could be expected from cometary impacts over … Read more

The Defense Advanced Research Projects Agency has demoed its Precision Urban Hopper robot, a wheeled ground unit that can leap over 25-foot-tall obstacles and keep on truckin'.

Seen in the video below, released last week by the Sandia National Laboratory, the shoebox-size Hopper easily takes on a chain-link fence, bounces a bit after landing, and then keeps rolling. It seems that a piston-fired leg makes it fly.

The Precision Urban Hopper is being developed by Sandia and Boston Dynamics, creator of the famously creepy BigDog robot, for surveillance operations in urban terrain. Guided by GPS, it is designed to "… Read more

Injured soldiers and people with disabilities might one day benefit from a hydraulic hand that doubles finger strength. Scientists at the Department of Energy's Oak Ridge National Laboratory say a "mesofluidic" hand could be used to remotely disarm explosives and manipulate IEDs.

Mesofluidics is the study of applying pea-size hydraulics to applications requiring significant power in a limited space.

So far, the team at the Tennessee laboratory has developed an artificial finger made up of 25 moving parts. It can deliver 20 pounds of pinch force, about double that of a human finger, while remaining lightweight and … Read more

They pissed it. You may have missed it.

Recently, there was a fascinating glow in the sky that moved observers to ponder just what it might be.

I am assuming that Space.com is an authoritative source of information, for it informs me that the glow that was seen in the sky by so many last Wednesday was, indeed, astronauts' urine.

NASA spokeswoman Kylie Clem told a press conference that this aurora boreapiss was the result of the space shuttle Discovery releasing an unusual amount of water and urine into outer space.

I have never consciously weighed urine--not even my … Read more

NASA's embattled Constellation moon program, thought by many to be on life support in the face of ongoing budget cuts, is technically feasible, "soundly" managed, and capable of putting American astronauts back on the moon as planned in the 2020s, the chairman of a manned space review said Tuesday.

But if the Obama administration and Congress fail to restore some $3 billion in lost funding, he said, NASA will be unable to return to the moon or venture beyond the confines of low-Earth orbit.

Norman Augustine, former CEO of Lockheed Martin and chairman of Review of U.… Read more
