In today's Robot News, "CubeStormer 3" has set a new world record for solving a Rubik's Cube—just 3.253 seconds. This is a field known as "speedcubing," and the human record is just over 5.5 seconds. I, for one, welcome our new robot speedcubing overlords.
CubeStormer 3 breaks the old world record held by—wait for it—CubeStormer 2, which took 5.27 seconds to solve a randomized cube. Here's video; the action starts about nine seconds in, and it goes very quickly, of course.
And here's an overhead look at the process with less hype at the beginning and end:
The CubeStormer systems use LEGO Mindstorms robotics controlled by smartphones to manipulate the cubes. (The phones use cameras to observe the layout of the cube, then figure out the next move, and command the LEGO robot arms to do it.) It's easier to see what's going on by looking at the slightly slower CubeStormer 2, shown here:
And if you've got time, parts, and patience aplenty, here's a time-lapse video showing the creation of a (non-CubeStormer) LEGO speedcubing machine:
When Sony released its robotic dog Aibo in 1999, marketing it as “Man’s Best Friend for the 21st Century,” sales were impressive. But the public fascination didn’t last forever. Even though it was low-maintenance and allergy-free, most dog-lovers still preferred the pets they had to clean up after and feed. Aibo was discontinued seven years later.
Now, Mashable reports that Aibo is making a comeback, and it’s been given a few updates to make it a better fit for the current decade. When the robot companion returns to shelves in spring of 2018, it will double as a smart home device. That’s a big step up from the early Aibos, which couldn’t do much beyond playing fetch, wagging their tails, and singing the occasional song.
Sony’s original Aibo team, which was redistributed throughout the company in 2006, has reformed to tackle the project. Instead of trying to replace your flesh-and-blood Fido at home, they’ve designed a robot that can compete with other AI home speakers like Amazon Echo and Google Home. The new dog can connect to the internet, so owners will be able to command it to do things like look up the weather as well as sit and fetch. Aibo will run on an open source software, which means that third party developers will be able to program new features that Sony doesn’t include in the initial release.
While Aibo is often remembered as a turn-of-the-millennium failure, it's still beloved in some communities. In 2015 The New York Times published a short documentary profiling owners in Japan who struggle to care for their robots as parts become scarce. When the pets break down for good, some of them even hold Aibo funerals. It will soon became clear if the 2018 models inspire a cult following of their own.
A new Honda robot could signal the future of disaster response technology. According to IEEE Spectrum, the Japanese company recently debuted a prototype for a cutting-edge disaster-response robot agile enough to climb ladders, ascend stairs, maneuver over pipes, and move through narrow spaces, among other capabilities.
Honda unveiled the prototype for the E2-DR at September’s IEEE/RSJ International Conference on Intelligent Robots and Systems in Vancouver. The slow-moving humanoid robot looks like a beginning skater stepping onto the ice for the first time, stepping cautiously up stairs and through small spaces, but the fact that it can navigate these kinds of obstacles is a feat. Scaling ladders and walking up and down stairs are usually no easy tasks for robots, and both are among the challenges featured in the annual DARPA Robotics Challenge obstacle course—which is infamous for making very, very expensive robots fall all over the place.
Designed to inspect, maintain, and provide disaster response in places like factories and power plants, the E2-DR is 5.5 feet tall, weighs around 187 pounds, and can run for about 90 minutes at a time. Crucially, it’s less than 10 inches thick back-to-front, allowing it to squeeze through small corridors laterally.
The robot can reverse its knees to allow it to keep them from bumping against stairs as it walks, and its hands can grip ladders and rails. It can also open doors and climb on all fours. It’s equipped with rangefinders, cameras, and 3D sensors so that it can be piloted remotely.
Because it’s designed to work in disaster zones (like within the Fukushima power plant) the robot has to be able to withstand water, debris, dust, and extreme temperatures. It’s already been able to climb up and down a ladder in the face of 1 inch-per-hour rain, according to Honda.
IEEE Spectrum notes that we haven’t seen it fall, and falling down is, despite how silly it looks in testing, an important thing to test before sending robots into the field. In unpredictable settings and rough terrain, it’s likely that a robot is going to misstep and fall down at some point, and it needs to be able to not just withstand the fall, but get itself back up.
The E2-DR is just a prototype, and Honda will continue to work on it for the foreseeable future. For now, though, it’s made an impressive start.
