Cutting Edge

Ongoing analysis of the trajectory of a piece of space junk that was believed to pose a possible threat to the International Space Station showed the debris would not pass close enough to the lab complex to force the crew to seek refuge in their Soyuz lifeboats, a NASA official said late Friday.

An agency spokesman said the station's six-member crew would be awakened early, at 10 p.m. EST as planned, but the astronauts would be told to go back to bed and not to press ahead with a tentative plan to shelter in place aboard the station's Soyuz ferry craft.

Earlier Friday, NASA flight controllers predicted the debris, of unknown origin, could pass within about six-tenths of a mile of the space station at 10:48 p.m., toward the end of the crew's normal sleep period. During the evening planning conference Friday afternoon, the astronauts were told to plan on getting up early so they could make their way to the Soyuz lifeboats by around 10:30 p.m. if necessary.

"The ballistics are saying they are looking at conjunction with space debris," Russian mission control radioed. "As you know, this is something we are prepared for. In the past, we have performed avoidance maneuvers, but this time maneuvering away from the path of the debris is not an option.

"Because we cannot perform avoidance maneuver, you will have to ingress Soyuz vehicles. Both Soyuz crews should be in their vehicles. This is what we have. We are going to work on the ballistics data to get greater precision, but right now we are in the red box. The probability of collision is non zero."

NASA flight controllers told the astronauts the tracking data was uncertain and that engineers did not yet have confidence in the trajectory projections. Pending additional analysis later in the afternoon, the crew was told to play it safe and plan on boarding the Soyuz lifeboats after shutting internal hatches in the U.S. segment of the lab complex.

After additional analysis, however, flight controllers concluded the unidentified debris would not pose a threat to the station, according to a NASA spokesman.

Last March, the station's three-man crew - Mike Fincke, Yury Lonchakov and Sandra Magnus - faced a similar situation and briefly took refuge in the lab's single Soyuz ferry craft when another piece of debris from an old rocket motor made a close approach.

There are more than 18,000 pieces of space junk in low-Earth orbit the size of a baseball and larger. U.S. Strategic Command prioritizes radar tracking to protect manned spacecraft first, followed by high-priority military and civilian payloads.

NASA monitors an imaginary volume around the space station roughly the shape of a pizza box measuring 0.466 miles thick and 15.5 miles square.

"Initially, we have a screening box, which is .75 kilometers radial miss, which would be up or down, by 25 kilometers in cross track, which would be left or right, by 25 kilometers down track, which is either in front or behind us," space station Flight Director Ron Spencer said in September.

"Space Command will alert us of any debris objects out there that are going to get that close to us. Then they increase tasking on those objects to try to get a better solution and decrease the uncertainty. Then we calculate a probability of collision based on the data Space Command gives us."

Spencer said NASA has two levels of concern.

"We have two thresholds, yellow and red," he wrote in an email exchange. "The yellow is 1-in-100,000 and the red is 1-in-10,000. We will not take any action if it is below the yellow threshold. If it between the yellow and red, we will only take action if it is easy to do so without impacting the mission. For a red threshold violation we will take action in most cases."

Updated at 6:45 p.m. EST: NASA officials say analysis shows the space debris in question poses no serious threat to the International Space Station.

You've probably heard of or even owned a computer that automatically turns off its hard drive when it senses shock or heavy vibrations. That is an example of sensitive human-machine intimacy. Another example I like is tilting the iPhone to use it as the driving bar for my racing games. Well, that nifty human-to-computer interaction is about to go to whole new level.

HP announced Thursday a new inertial-sensing technology that enables the development of digital micro-electro-mechanical systems (MEMS) accelerometers that are up to 1,000 times more sensitive than those in high-volume products currently available.

A MEMS accelerometer is a sensor that can be used to measure vibration, shock, or change in velocity. When implemented, this allows the device to "feel" the environment it is in.

According to HP, the new sensing technology--the result of HP's 25 years of nano-sensing research--includes multiple detectors as part of a complete sensor network and therefore is capable of real-time data collection, management evaluation, and analysis. This information enables users to make better, faster decisions, and take subsequent action to improve safety, security, and sustainability.

Say salam wa aleikum to an Arabic-speaking android developed at United Arab Emirates University and billed as the first of its kind in the world. It could enter mass production to help people at shopping malls.

The Ibn Sina robot, named after an 11th century philosopher, can recognize faces, converse with people by speaking in classical Arabic, connect to the Internet, and retrieve information. As seen in the video below, it can also exchange kisses with people.

Software for Ibn Sina was developed by a team led by computer science assistant professor Nikolaos Mavridis, with the mechanics by Hanson Robotics. Mavridis says some companies have approached his lab and asked about using the turban-wearing, bearded bot in shopping malls or as a receptionist.

Doubtless Ibn Sina, known as Avicenna in English, would have been pleased.

The International Space Station isn't just an orbiting laboratory, spaceship testing ground, and multinational geek fest--it's also the world's highest (250 miles) and fastest (17,500 mph) computer network. We burrow under its metal skin and siphon out its most interesting specifications, like some kind of star-hopping alien data vampires (but without the plutonium-coated fangs).

Manning security checkpoints is hazardous duty, but vehicles still must be checked. So the U.S. Army is helping develop products that will allow soldiers to do their job, preferably from a distance.

Researchers and scientists at the U.S. Army Tank Automotive Research, Development and Engineering Center (aka TARDEC) have focused on semi-autonomous robotic systems capable of remotely inspecting a vehicle's undercarriage for explosives or roam the line looking for suspicious activity.

TARDEC will showcase a couple of its favorite autonomous robotic systems this week at the Michigan Security Network Market Leadership Conference. Both units were developed for military and homeland security applications, such as airport and seaport inspections and hazardous substance detection. But nothing says you can't deploy them at your next block party.

Here's a sneak peek.

The ODIS performs under-vehicle inspections to detect explosives, contraband, and radiological, chemical, and biological threats. It was developed in partnership with the DOD Joint Robotics Office, Utah State University, and Kuchera Defense Systems.

The SpectorRobotic System, developed by TARDEC in conjunction with Autonomous Solutions, is an omnidirectional platform designed to perform under-vehicle visual inspections for weapons, explosives, or other contraband, while keeping inspectors out of harm's way. It's currently being manufactured for use in Iraq and Afghanistan.

"Autonomous robotic systems like the Spector and ODIS offer military and civilian personnel a modular, mobile, low-cost, safe alternative to conventional inspection and patrol operations," said David J. Thomas, TARDEC Associate Director of Intelligent Ground Systems. "These devices can and do save lives while providing security representatives with the most advanced detection and inspection technologies available in the ground systems arena."

Advanced gamer hardware may soon allow PacBot operators to tell exactly how hard a robot's grip is, allowing soldiers to more safely pick up and handle fragile or dangerous objects, while also increasing their situational awareness.

Novint Technologies, a company that makes 3D touch controllers for video and computer games, announced last month that it has been awarded a subcontract to co-develop a remote touch kit (RTK) for the iRobot unmanned ground vehicle (UGV) PacBot.

The new RTK will allow soldiers to tactually sense the amount of force a robot is exerting from a safe operating distance--a first for military UGVs, according to Novint. It will also increase spatial sensitivity.

For example, the soldier would feel the bumps and jerks when driving the robot, thus improving performance over rugged terrain. The operator would also "feel" when the robot's arm touches a wire--a not inconsequential feature when dealing with booby-trapped IEDs. The result, the company says, will be "greatly reduced task times and operator burden, increased dexterity and situational awareness, and reduced training."

"As demand for unmanned military robots continues to grow, Novint's touch technology will play a crucial role in enhancing operator control during mission-tasks such as bomb disposal or surveillance," Novint Technologies CEO Tom Anderson said in a statement.

It does this through applied Haptics, the art and science of applying sense of touch to human interaction with computer generated environments. A Haptic device makes touching a virtual object seems real and tangible.

The project is funded by the Secretary of Defense Joint Ground Robotics Enterprise through the Robotics Technology Consortium.

KENNEDY SPACE CENTER, Fla.--A preliminary look at data from NASA's Ares I-X test flight Wednesday shows the towering rocket performed as well or better than computer modeling predicted during the climb out of the dense lower atmosphere, a senior NASA manager said Friday.

One of three huge parachutes failed to inflate during the spent booster's descent to the Atlantic Ocean and a second chute only inflated halfway, resulting in a hard splash down that caused the rocket's case to buckle.

But Mission Manager Bob Ess said the parachute system, flying for the first time, was designed for NASA's planned Ares 1 rocket, which is 15 percent lighter than the test version, and that engineers will have plenty of time to correct whatever went wrong.

"No one is concerned about it," Ess said. "In fact, the parachute guys were ecstatic, was their words, (about) the information they got from this flight. They really wanted to test this out."

The Ares I-X rocket was designed to match the characteristics of NASA's planned shuttle replacement, the more powerful Ares I. The test version featured a four-segment shuttle booster, a dummy fifth segment housing guidance and control equipment and an unpowered mockup of the rocket's upper stage and crew capsule.

The 327-foot-tall test rocket was launched Wednesday from shuttle complex 39B at the Kennedy Space Center. The major goals of the unmanned six-minute flight were to collect engineering data on how the tall, slender rocket flew through the lower atmosphere, how the structure responded to aerodynamic and acoustic forces and how the new parachute system, scaled for the planned Ares I, performed.

During the initial seconds of flight, the rocket's nozzle moved 1 degree as planned to help the booster "walk off" the pad, preventing its hot exhaust plume from hitting the upper sections of the shuttle service gantry. As expected, the plume caused minor damage to the lower sections of the gantry, but Ess said that would not be a problem for the new service tower that will be used for Ares rockets.

If I wasn't so worried about traumatizing the kids in my neighborhood, dispensing trick or treat candy in this creepy spider bot pumpkin would be awesome.

It runs C on an Axon microcontroller. It uses all digital servos and can lift over twice its body weight. The software (soon to be given out open source) allows for six synchronous degrees of motion. Future additions will include foot sensors and a remote control option.

Based on that info, and other nuggets gleaned from the Trossen Robotics forums, you might be able to have a Creeper2 bot of your own ready for next year.

Or, better yet, put a Santa head on top of that thing and march it out in the living room on Christmas morning. Your kids are sure to have suppressed memories of it that will bubble up to the surface years and years from now causing a dramatic and crippling meltdown. Priceless.

MIT intends to revolutionize GPS navigation by making it friendly and predictive, using a friendly robot helper to anticipate your needs. The Affective Intelligent Driving Agent (AIDA) is a robot head on an articulated neck, reminiscent of movie robots from the 1980s, that mounts in the center of the dashboard.

It incorporates an expressive "face" that can smile, look sad, show warning signs, and even wink at you. AIDA was developed as a collaboration between the Personal Robots Group at the MIT Media Lab, MIT's SENSEable City Lab, and Volkswagen Group of America's Electronics Research Lab.

AIDA's expressive behaviors are designed to endear the device to you as it helps in your daily navigation. The robot learns your daily commute and which areas you frequent for which purposes.

For example, if you always head to a particular district in your city around dinner time, it will assume you like to eat dinner there. After it memorizes your commute, it will automatically plug in your route to work when you get into the car on a weekday morning. If you go to a hotel for a dalliance every Thursday at noon, it will probably give you a wink and a knowing grin as it maps the route for you.
