NASA Spacebot, what big eyes you have
Space isn't exactly the safest of places for squishy meatbags like us, what with the lack of atmosphere and all. But when satellites in orbit break, somebody's got to fix them. That's why NASA is developing a robotic remote viewing system called the VIPIR (Visual Inspection Poseable Invertebrate Robot). It leverages an articulating borescope as well as a zoom-lens camera to help Earth-bound engineers troubleshoot external issues aboard the ISS, launch vehicles and satellites. NASA is currently in the second phase of operational testing with the VIPIR. Eventually the space agency hopes to eventually pair these eyes with Dextre, Canada's dual-armed spacebot that is currently serving aboard the ISS.
Robot fixes robot on the ISS so astronauts don't have to (video)
When something goes wrong with the ISS, astronauts usually don their suits and brave the harsh conditions of space to do what needs to be done. But the space station's Canadian robotic arm (aptly called Canadarm2) is currently attempting to fix itself with minimal human input, thanks to its very special passenger -- a multi-limbed helper robot called Dextre. Canadarm2 carries the handymanrobot around to fix anything that's broken on the ISS or to catch unmanned vehicles headed for the station, such as SpaceX's Dragon capsule. This time, though, Canada's Space Agency is remotely controlling Dextre to move and replace old cameras on Canadarm2 itself.
Canada puts its robot arms on $5 bills, leads the space currency race
Americans like to tease Canadians about their colorful (and often animal-themed) money, but we think the tables might just have turned. When the Bank of Canada issues a new $5 polymer bill this November, one side will include both the Canadarm2 and Dextre manipulator robots in tribute to the nation's work on both the Space Shuttle and International Space Station. Let that sink in for a moment: a country's currency will reference space robots alongside the usual politicians. The only thing dampening the awesomeness is the irony of it all, as it's an ode to technology in a format that's being destroyed by technology. Still, we'll consider the $5 note a victory for geeks everywhere when we're buying a box of Timbits.
Canada's Dextre robot refuels faux satellite from the ISS in first-of-a-kind test
Move over, Canadarm. You may have helped the space shuttle fleet repair the Hubble Telescope and build the International Space Station, but there's another robotic tool that's the apple of the Great White North's eye. Dextre, the Canadian Space Agency's dual-armed mechanical "handyman," has successfully refueled a faux satellite from the ISS as part of NASA's and the CSA's joint Robotic Refueling Mission. Not only did the exercise demonstrate how satellites could be juiced up in space and have their lives extended, but the CSA says it's a first for the history books, to boot. Since 2011, Dextre completed a trio of tests to show how it could service satellites that weren't built for being pried opened in space. Late this week, NASA and CSA robotics controllers removed two safety caps from a washing machine-sized mock satellite, snipped two sets of retaining wires and pumped in a bit of ethanol. Sure, you could take a Frankenstein-like approach and cobble together new satellites from old ones, but Dextre's trials indicate there's promise for a proactive tactic that would keep existing hardware humming.
NASA robotic gas station successfully installed -- our Jetsonian dreams (almost) fulfilled
So we won't be zipping around with wife and kids in a flying car anytime soon, but NASA brought us ever closer to a Jetsonian future, yesterday, with the installation of its Robotic Refueling Mission (RRM) experiment. Fifteen minutes into their spacewalk, Mike Fossum and Ron Garan successfully installed the appropriate hardware on the International Space Station for pumping fuel to satellites in space. Using the Canadian-born Dextre (aka Special Purpose Dextrous Manipulator) as a gas station attendant, the RRM will eventually be used to refuel and perform minor repairs to satellites in orbit, potentially extending the time they can stay aloft. Now that that's underway, how 'bout y'all get to work on making Rosie a reality?
Dextre robot now fully assembled, ready for testing
Apparently, the folks aboard Space Shuttle Endeavour aren't wasting any time piecing Dextre together (or jamming to their iPods), as just days after we first heard about this creature's future in space, now we're hearing that he's totally assembled and ready to rock. The bot, which is formally known as the Special Purpose Dextrous Manipulator, has been fitted with various tools and cameras and is all set to "undergo a series of tests and trials before it is asked to do major tasks." Godspeed, young Dextre -- hopefully you'll have more success than Ted and Gadget.
Canadian-built Dextre robot set for delivery to space station
It may be not be the only bot on the block for long but, for now at least, the Canadian-built Dextre robot has the spotlight to itself, with it set to blast off Tuesday on board the shuttle Endeavor for delivery to its new home on the International Space Station. As USA Today reports, the robot has been some ten years in the making (at a cost of $210 million), and is designed to handle many of the tasks that would otherwise be done by astronauts on spacewalks. Those astronauts will still have a job for a while yet, with one of the main tasks during Endeavor's mission obviously being the assembly of Dextre, which is currently broken down into nine parts. Even after that's done, however, Dextre apparently won't start work until sometime in 2009, at which point it'll be able to replace nearly 140 parts on the ISS, and be controlled either by mission control or the crew on the space station.
