Soil Studies Continue At Phoenix Mars Lander Site
Pasadena CA (SPX) Aug 13, 2008Vibration of the screen above a laboratory oven on NASA's Phoenix Mars Lander on Saturday, Aug. 9, succeeded in getting enough soil into the oven to begin analysis. Commands were sent for the lander's Thermal and Evolved-Gas Analyzer (TEGA) to begin analysis Sunday of the soil sample from a trench called "Rosy Red." Phoenix's robotic arm delivered soil Thursday from the Rosy Red trench ... more 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 |

Paris, France (SPX) Jul 31, 2008The field of robotics could be poised for a breakthrough, leading to a new generation of intelligent machines capable of taking on multiple tasks and moving out of the factory into the home and general workplace. The great success of robots so far has been in automating repetitive tasks in process control and assembly, yielding dramatic cuts in production, but the next step towards ... more Phoenix Lander Working With Sticky Soil 
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 |

Tucson AZ (SPX) Jul 17, 2008A powered rasp on the back of the robotic arm scoop of NASA's Phoenix Mars Lander successfully drilled into the frozen soil and loosened material that was collected in the lander's scoop. Images and data sent from Phoenix early Wednesday indicated the shaved material in the scoop had changed slightly over time during the hours after it was collected. The motorized rasp -- located on ... more NASA Robots Perform Well During Arctic Ice Deployment Testing 
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
