NASA Scientists Control Robotic Arm With Kinect And Oculus Rift

fb share tweet share

NASA JACORobots in space — two great tastes that taste great together. They might go to Mars ahead of the humans to set up facilities, 3-D printed robotic spiders might build spacecraft, and robots might make isolated astronauts less lonely. Yet another robotics advancement at NASA pairs humans and robots, allowing humans to control the actions of robotic counterparts using a good ol’ Microsoft Kinect and something called the Oculus Rift.

The Kinect sensor provides the position tracking, while the Oculus Rift virtual reality headset allows for rotational tracking and the first-person experience one gets when playing a game in virtual reality. When the user has the view he needs, he can perform tasks which control the real-time movements of robotic arm. NASA has been using a JACO robotic arm developed by Kinova, a Canadian company that specializes in rehabilitation and research. The arm has three fingers, six degrees of freedom, and is designed to represent a “new generation of lightweight portable robotic manipulators.”

Cassini Offers A New Glimpse Of The Pale Blue Dot

The Day the Earth SmiledGiven my fascination with the universe, my love for Carl Sagan, and my hopes that the reboot of Cosmos will take viewers by storm, it’s only appropriate that my last post of the year would be about space — and more specifically, about a planetary scientist who arranged a pretty awesome photo op of Earth from the Cassini spacecraft.

Carolyn Porco, leader of the Cassini Imaging Science team and professor of astrophysics and planetary scientists, is following in Carl Sagan’s footsteps, especially when it comes to appreciating the significance of Earth as the “pale blue dot.” The phrase refers to a photograph taken in 1990 by the Voyager 1 probe on its way out of the Solar System, nearly four billion miles from Earth. At Sagan’s request, NASA had the probe turn around and take a photo of Earth, which Sagan then elegantly wrote about. While the photo provides some perspective on the enormity of the universe and the relative smallness of Earth, the original image wasn’t actually that good, and Porco has been wanting to update that image for a long time.

DARPA’s Robotics Challenge Narrows The Field To Eight Finalists

SCHAFT robotDARPA’s Robotics Challenge, where teams compete to design and develop disaster response robots,
kicked off in June, with the software-based Virtual Robotics Challenge. For this first phase, teams create software and ran it on a robotic simulation. The challenge has now moved from virtual to physical, and the trials have just wrapped up, leaving a field of eight finalists that will compete in the Grand Challenge next year. In case you were wondering, the winner walks away with $2 million in prize money.

Merry Christmas! Astronauts Conduct Emergency Repairs On ISS Cooling System

spacewalkUnless his flying reindeer are truly amazing, like Falcor, Santa probably doesn’t make it to space. Or maybe he does, and that’s actually where he is the other 364 days of the Earth year. A galactic sleigh would have come in pretty handy at the ISS this Christmas, as astronauts had to attend to an emergency situation that led to a holiday spacewalk. You know, to take in all the lights.

I mean, they’re not decorating the tree, making a holiday dinner, or getting drunk on eggnog, so why not?

American astronauts Rick Mastracchio and Michael Hopkins have gotten to walk in space twice in the past four days. Today’s was the second Christmas Eve spacewalk ever. Is there a best day for a spacewalk? I think I’d like to do it on New Year’s Day, maybe. I probably wouldn’t enjoy an emergency spacewalk at any time, though, and that’s what these were. NASA helpfully tweeted along the way and provided a video feed.

Asteroid Hunting Spacecraft NEOWISE Is Back In Business

fb share tweet share

NEOWISE imageForget diamonds — asteroids are the hottest rocks out there. And unlike most objects, celestial or otherwise, asteroids have a particularly compelling dichotomy. On the one hand, they’re mineable and they provide a wealth of resources that could benefit us on Earth, as well as catalyze space exploration. On the other hand, they present for some dodgy spacecraft flying conditions, obliterated the dinosaurs, and have wreaked havoc in Russia. Along with a slew of movies about asteroid apocalypses, these events have galvanized scientists and governments into action to detect (and hopefully prevent) threats posed by asteroids. Regardless of whether you think asteroids are cool or terrifying, or a bit of both, we have to be able to find them in order to do anything else with or about them. NASA has put out a call to help it find asteroids, but now the single best asteroid hunter, NEOWISE, is back in business.

Meet Valkyrie, NASA’s Superhero Robot

fb share tweet share

ValkyrieWe’ve done lots of posts here on GFR about NASA, many of which bemoan the state and the budget of the beleaguered agency. Now NASA has something that just may solve all of its problems — a superhero robot.

Valkyrie, who shares a name with female characters from Norse mythology who decide which soldiers die and which live, but who looks more like Iron Man, has the stature of a superhero at 6 feet tall and 275 pounds — it even sports a glowing NASA logo on its front. Engineers at the Johnson Space Center in Houston built Valkyrie in just nine months as part of this month’s DARPA Robotics Challenge Trials. This means Valkyrie will have to prove its disaster-thwarting meddle by driving vehicles, clearing debris, cutting through obstructions, climbing ladders, turning valves and knobs, and other physical tasks that any life-saving superhero needs to be able to perform.
