ESA successfully tests controlling a robot on Earth from orbit

10:13 am

The European Space Agency (ESA) has successfully completed a test program, proving that an astronaut in orbit on ISS can control and operate a small robot on Earth.

Astronaut Luca Parmitano aboard the ISS [in 2019] operated the gripper-equipped ESA Interact rover in a mock lunar environment inside a hangar in Valkenburg, the Netherlands to survey rocks and collect samples. The two-hour space-to-ground test was a success, overcoming a two-way signal delay averaging more than 0.8 seconds and a data packet loss rate of 1% plus.

The value of this test is obvious. It shows that astronauts will be able to use small rovers and robots in remote operations, such as sending a probe down to the surface before landing themselves, or once on the planet sending that probe into dangerous terrain as a scout, while the astronaut stays back in safety.

At the same time, the robot used and the tasks it completed were all relatively simple. Moreover, the “mock lunar environment” was hardly realistic. A lot more work is needed before such a robot is functional in a real planetary environment.

Robots playing soccer

6:01 pm

An evening pause: This is a clip from a robot competition in 2019 of what are called “kidsized” robots. Short but entertaining, especially because it demonstrates the relative stupidity and slow incompetence of state-of-the-art robots. Future versions might someday get to the level of Terminator, but these robots show that we are fortunately nowhere that close today.

Robots

6:01 pm

An evening pause: This sequence from the animated film Robots (2005) is a very typical scene from almost every modern Hollywood film, whether real or animated (though the difference is getting harder to see as they put more and more CGI in every film). Regardless, it is fun, and takes the idea of a Rube Goldberg device to a very strange extreme.

Saudi Arabia gives robot citizenship

10:36 am

As part of a publicity stunt to encourage investment, Saudi Arabia has given citizenship to a new robot, designed to show human emotions by facial expressions.

A humanoid robot took the stage at the Future Investment Initiative yesterday and had an amusing exchange with the host to the delight of hundreds of delegates. Smartphones were held aloft as Sophia, a robot designed by Hong Kong company Hanson Robotics, gave a presentation that demonstrated her capacity for human expression.

Sophia made global headlines when she was granted Saudi citizenship, making the kingdom the first country in the world to offer its citizenship to a robot.

Below the fold I have embedded the video of Sophia’s conversation with the host. It is obvious that most of the conversation was scripted. It is also obvious that robots still have a long way to go before their facial expressions appear natural to the human eye.

Robots communicating in languages humans can’t understand

10:04 am

The rise of the machines! When two bots of its artificial intelligence software (AI) began to communicate in a language humans could not understand, Facebook researchers put a stop to it.

At first, they were speaking to each other in plain old English. But then researchers realized they’d made a mistake in programming. “There was no reward to sticking to English language,” says Dhruv Batra, visiting research scientist from Georgia Tech at Facebook AI Research (FAIR). As these two [robot] agents competed to get the best deal–a very effective bit of AI vs. AI dogfighting researchers have dubbed a “generative adversarial network”–neither was offered any sort of incentive for speaking as a normal person would. So they began to diverge, eventually rearranging legible words into seemingly nonsensical sentences.

…Facebook ultimately opted to require its negotiation bots to speak in plain old English. “Our interest was having bots who could talk to people,” says Mike Lewis, research scientist at FAIR. Facebook isn’t alone in that perspective. When I inquired to Microsoft about computer-to-computer languages, a spokesperson clarified that Microsoft was more interested in human-to-computer speech. Meanwhile, Google, Amazon, and Apple are all also focusing incredible energies on developing conversational personalities for human consumption. They’re the next wave of user interface, like the mouse and keyboard for the AI era.

The other issue, as Facebook admits, is that it has no way of truly understanding any divergent computer language. “It’s important to remember, there aren’t bilingual speakers of AI and human languages,” says Batra. We already don’t generally understand how complex AIs think because we can’t really see inside their thought process. Adding AI-to-AI conversations to this scenario would only make that problem worse.

The article makes some interesting points about the advantages of allowing this AI software to create its own language. For me, none of these arguments are very convincing.

More new robots from Boston Dynamics

4:34 pm

The video at the link shows off SpotMini, of video of which I posted previously. However, the first robot shown is one they have named Handle and is something they admit could be “nightmare-inducing.” It walks upright on two legs, but instead of feetpods it has wheels, giving it the ability to move very fast. And for some reason, they put its arms on backwards so that the elbows bend inward instead of outward.

Watch the video. The robot design work here is truly breath-taking.

Want to buy a used NASA robot? You can!

8:55 am

Link here. The robot was developed in the 1960s to test spacesuits, though because it leaked oil it was never used.

In fact, this particular 1960s NASA project appears to be a perfect example of “engineers gone wild!” The website explains that the robot was an attempt to replace human test volunteers.

Unfortunately, pressure suits aren’t like coveralls. They’re complex pieces of engineering. A human can provide qualitative information about how (un)comfortable a suit is, but cannot gauge the forces involved with the precision and accuracy that an an engineer needs. In addition, testing pressure suits with volunteers can be grueling, unpleasant and even painful.

In the end, however, the robot didn’t work and the testing was done by humans, probably for a lot less than the $175,000 they spent (in 1960s dollars) to build two of these robots. One however is now being auctioned off, and could serve wonderfully as a great piece of interesting artwork in someone’s home.

Russian robot escapes!

9:16 am

A robot being tested by Russian engineers ended up on its own on a public street, baffling passersby and traffic.

“The robot was learning automatic movement algorithms on the testing ground, these functions will feature in the latest version of the Promobot.” The co-founder of the robot’s maker, Oleg Kivokurtsev, told ura.ru news agency. “Our engineer drove onto the testing ground and forgot to close the gates. So the robot escaped and went on his little adventure.” Kivokurtsev explained.

The team only noticed their brainchild was missing 45 minutes into the robot’s travel stint and by the time they located it, there was already a crowd of puzzled citizens and the police had arrived.

I have a suspicion that this was not really an accident, but instead a publicity stunt, but have no way to confirm this suspicion.

Robotic servicing demo resumes on ISS

9:26 am

After a two year hiatus, engineers have resumed experiments on ISS to demonstrate robotic servicing of satellites in space.

Known by its creative team as the “little ISS experiment that could,” RRM broke uncharted ground in 2011-2013 with a set of activities that debuted robotic tools and procedures to refuel the propellant tanks of existing satellites. Its second phase of operations, which took place in April and May and will resume again later in 2015, offers something entirely different and just as disruptive, says Reed. “We’ve outfitted the RRM module with new hardware so we can shift our focus to satellite inspection, instrument life extension, and even techniques for instrument swap-out,” says Reed. Such servicing technologies could open new possibilities for owners of spacecraft in low and geosynchronous Earth orbit, he says.

Many of the designs of this demo project are based on actual research satellites that need refueling or repair. Thus, if the robot can do the work on ISS, it is likely it can also do the work at the satellite itself.

A compilation of robots falling down at the DARPA Robotics Challenge

12:18 pm

More information here. It seems that on the dry run prior to the start of competition, not many robots fell over. Then on Day 1, when the competition was for real, a lot had problems standing up.

The impressive thing about these falls is that, although they look pretty bad, the robots were just fine (well, most of them). After humans got them back on their feet and gave them a reboot, the machines were ready to run again. Team IHMC’s Atlas fell twice during their run and it still scored 7 points (of a maximum of 8). Team MIT’s Atlas had a bad stumble out of the vehicle and also went on to complete most of the course. So it’s a good thing that robots are falling at the DRC Finals—that’s how we’re going to make them better.

On Friday an astronaut on ISS controlled and steered a rover on Earth.

While zipping around Earth several hundred miles above the planet’s surface, European Space Agency astronaut Luca Parmitano drove a 220-pound (100 kilograms) rover across a moon-mimicking landscape here at NASA’s Ames Research Center, even ordering the robot to deploy a simulated film-based radio telescope antenna.

Robot engineers have successfully built a fleet of small flying robot helicopters that can fly individually or as complex large arrays.

Robot engineers have successfully built a fleet of small flying robot helicopters that can fly individually or as complex large arrays. With video.

Applying this biologically-inspired solution to swarms of robots could enable a wide range of applications. Swarms of robots could be used to explore other planets, or search a large area for a missing person. When a larger payload needs to be lifted, groups of robots would combine to make a larger flying platform and when that job was done, disperse into smaller groups that can cover a larger area. The advantage of distributed control in these scenarios is that there is no vulnerable central control unit which, if taken out, could bring down the entire mission.

Robotic refueling demo begins today on ISS

1:06 pm

A robotic refueling demo. designed and built by the same people who ran the Hubble Space Telescope repair missions, begins today on ISS, using Dextre.

This demo is designed to prove that a robot, operated from the ground, can refuel a satellite not designed for refueling. The demo satellite on ISS was built to match the design of several climate satellites already in orbit that will end up defunct in a few years if they can’t be refueled.
