Cutting Edge

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

Clearwire Communications has created a sandbox more than 20 square miles in size where developers can play with WiMax.

Clearwire announced on Tuesday the launch of the largest test area yet for its 4G WiMax service in Silicon Valley. Covering a wide area from Santa Clara to Mountain View to parts of Palo Alto, the company's Clear 4G WiMAX Innovation Network will let developers test the mobile broadband network on a large scale.

First announced in April by Clearwire, the Clear 4G WiMAX Innovation Network is seen as a testbed to prepare for the launch of commercial WiMax service … Read more

Detoured by bad weather in Florida, the shuttle Discovery dropped out of orbit and swooped to a flawless California landing Friday to close out a successful space station resupply mission.

Shuttle commander Frederick "C.J." Sturckow and pilot Kevin Ford fired the shuttle's twin braking rockets at 4:47 p.m. PDT to drop the ship out of orbit for an hour-long descent to Edwards Air Force Base.

After a steep plunge across the Los Angeles basin, Sturckow took over manual control at an altitude of about 50,000 feet above the Mojave Desert landing site and … Read more

Japan has developed a fitness robot to help its rapidly aging population stay in shape.

Taizo is a small humanoid bot that can perform a number of calisthenics routines. It's covered with a plush white material and looks like Frosty the Snowman in a pressure suit.

Taizo, a play on "taiso" (gymnastics), has 26 joints, or degrees of freedom, and can do about 30 moves, mostly while sitting down. Its internal structure is fairly simple and resembles many of the robot kits sold in hobby stores in Japan.

The National Institute of Advanced Industrial Science and Technology (AIST), a state-run research center, and General Robotix, a spinoff company, created Taizo to help lead groups of older Japanese in rehabilitation exercises and general fitness routines.

Taizo's head, hands, and feet are made of fiberglass reinforced plastic. Its body weighs about 14 pounds and stands roughly 2 feet tall. It can recognize simple voice commands and can link to external computers via Bluetooth and wireless LAN. A single battery charge allows it to operate for about two hours. … Read more
