Robots may enhance disabled people's lives
Rochester, N.Y. (UPI) Aug 11, 2008 A U.S. study foresees robots as improving both the quality and flexibility of the lives of people with disabilities that affect the use of their limbs. The robotics engineering research, sponsored by The National Science Foundation, utilized physiological information -- called bio-signals -- produced by the human body to improve external assistive devices called orthoses that help ... more Japanese Researchers Eye e-Skin For Robots 
Tokyo, Japan (AFP) Aug 12, 2008Japanese researchers say they have developed a rubber that is able to conduct electricity well, paving the way for robots with stretchable "e-skin" that can feel heat and pressure like humans. The material is the first in the world to solve the problems faced by metals -- which are conductive but do not stretch -- and rubber, which hardly transmits electricity, according to the team at the ... more Soil Studies Continue At Site Of Phoenix Mars Lander 
Tucson AZ (SPX) Aug 11, 2008NASA's Phoenix Mars Lander has continued studies of its landing site by widening a trench, making overnight measurements of conductivity in the Martian soil and depositing a sample of surface soil into a gap between partially opened doors to an analytical oven on the lander. Phoenix's robotic arm delivered soil Thursday from a trench informally named "Rosy Red" through a narrow opening to ... more U.S. military use of robots increases 
St. Louis (UPI) Aug 5, 2008 Military robots are no longer only science fiction, with the U.S. Army planning to have 30 percent of its forces composed of robots by 2020. Washington University Assistant Professor Bill Smart and doctoral student Doug Few said the Army's robots won't resemble robotic soldiers from movies such as "Star Wars" and "I, Robot." "When the military says 'robot' they mean everything ... more Japan's Toyota unveils next-generation scooter 
Tokyo (AFP) Aug 1, 2008Japan's Toyota Motor on Friday unveiled the Winglet -- a new two-wheel electric scooter to rival the Segway. The Winglet, which the automaker describes as "a personal transport assistance robot", can be controlled by shifting body weight, allowing the rider to go forward, backward and turn while standing upright. It cruises at a speed of up to six kilometres (four miles) per hour and ... more |

Tucson AZ (SPX) Jul 30, 2008Scientists and engineers on NASA's Phoenix Mars Mission spent the weekend examining how the icy soil on Mars interacts with the scoop on the lander's robotic arm, while trying different techniques to deliver a sample to one of the instruments. "It has really been a science experiment just learning how to interact with the icy soil on Mars -- how it reacts with the scoop, its stickiness ... more Phoenix Revises Method To Deliver Icy Sample 
Tucson AZ (SPX) Jul 29, 2008NASA's Phoenix Mars Lander's robotic arm will use a revised collection-and-delivery sequence overnight Sunday with the goal of depositing an icy soil sample in the lander's oven. "We are going to modify the process we ran on Sol 60 to acquire another icy sample and attempt to deliver it to TEGA," the Thermal and Evolved-Gas Analyzer, said Barry Goldstein, Phoenix project manager from NASA ... more Lander Collects Icy Soil But Needs To Work On Delivery 
Tucson AZ (SPX) Jul 28, 2008NASA's Phoenix Mars Lander's robotic arm collected a more than adequate amount of icy soil for baking in one of the lander's ovens but will need to adjust how it delivers samples. Engineers determined the rasping and scraping activity collected a total of 3 cubic centimeters of icy soil, more than enough to fill the tiny oven cell of the Thermal and Evolved-Gas Analyzer, or TEGA. ... more Trench On Mars Ready For Next Sampling By NASA Lander 
Tucson AZ (SPX) Jul 25, 2008NASA's Phoenix Mars Lander has groomed the bottom of a shallow trench to prepare for collecting a sample to be analyzed from a hard subsurface layer where the soil may contain frozen water. Images received Thursday morning confirmed that the lander's robotic arm had scraped the top of the hard layer clean during activities of Phoenix's 58th Martian day, or sol, corresponding to overnight ... more NASA's Phoenix Mars Lander Prepares For Next Sample Analysis 
Tucson AZ (SPX) Jul 25, 2008The latest activities of NASA's Phoenix Mars Lander have moved the mission closer to analyzing a sample of material, possibly icy soil, from a hard layer at the bottom of a shallow trench beside the lander. Overnight Tuesday to Wednesday, during Phoenix's 57th Martian day, or sol, since landing, Phoenix used its robotic arm to scrape the top of the hard layer in the trench informally named ... more |

Greenbelt MD (SPX) Jul 16, 2008Several snowmobiles navigated speedily over arctic ice and snow in Alaska's outback in late June. This scene might seem ordinary except that the recently unveiled snowmobiles are unmanned, autonomous, toy-size robots called SnoMotes - the first prototype network of their kind envisioned to rove treacherous areas of the Arctic and Antarctic capturing more accurate measurements that will help scie ... more Phoenix Mars Lander Rasping At Frozen Layer 
Tucson AZ (SPX) Jul 16, 2008A powered rasp on the back of the robotic arm scoop of NASA's Phoenix Mars Lander is being tested for the first time on Mars in gathering sample shavings of ice. The lander has used its arm in recent days to clear away loose soil from a subsurface layer of hard-frozen material and create a large enough area to use the motorized rasp in a trench informally named "Snow White." ... more Phoenix Mars Lander Extends Trench
Tucson AZ (SPX) Jul 16, 2008NASA's Phoenix Mars Lander is using its Robotic Arm to enlarge an exposure of hard subsurface material expected to yield a sample of ice-rich soil for analysis in one of the lander's ovens. The trench was about 20 by 30 centimeters (8 by 12 inches) after work by the arm on Saturday. The team sent commands yesterday to extend the longer dimension by about 15 centimeters (6 inches). ... more Sample-Collection Tests By Phoenix Lander Continue 
Tucson AZ (SPX) Jul 11, 2008NASA's Phoenix Mars Lander's science and engineering teams are testing methods to get an icy sample into the Robotic Arm scoop for delivery to the Thermal and Evolved Gas Analyzer, or TEGA. Ray Arvidson of Washington University in St. Louis, Phoenix's "dig czar," said the hard Martian surface that Phoenix has reached proved to be a difficult target, comparing the process to scraping a side ... more NASA's Phoenix Mars Lander Uses Soil Probe And Swiss Scope 
Pasadena CA (SPX) Jul 11, 2008NASA's Phoenix Mars Lander has touched Martian soil with a fork-like probe for the first time and begun using a microscope that examines shapes of tiny particles by touching them. Phoenix's robotic arm pushed the fork-like probe's four spikes into undisturbed soil Tuesday as a validation test of the insertion procedure. The prongs of this thermal and electrical conductivity probe are about ... more
