Give This Rubik-Solving Robot a Hand (Or at Least a Few Fingers)!

Wait a minute, didn’t you write about robots and Rubik’s Cubes just last week?

Yes, gentle reader, I certainly did.

But, as it turns out, that iconic little puzzly cube and all its twisty brethren are incredibly useful to AI and robot designers.

Not only do the acts of pattern recognition, visual assessment, and solving provide ample challenges to programmers — both in terms of speed and efficiency — but the physical manipulation of the cube itself is a frequent subject of testing.

In this particular case, a robot has been developed which can solve the cube one-handed. And, as eloquently stated in this Gizmodo article, that’s a feat in itself:

At one point in time, it was considered an accomplishment when a robot arm could pick up something as delicate as an egg without crushing it between a pair of pincers. But as researchers from the University of Tokyo’s Ishikawa Senoo Lab demonstrate — with the assistance of a high-speed camera monitoring the subtle movements — this agile three-fingered hand can manipulate and reposition Rubik’s fiendish puzzle cube with impressive dexterity.

Check it out:

This is a very different mechanical rig when compared to some of the other speed-solving rigs we’ve seen before. Instead of an elaborate array of motors and manipulators, it’s simply a few limber fingers.

This level of dexterity could prove to have all sorts of applications, from robotic surgery and meal preparation to improving bomb-defusing equipment and hazardous material disposal.

And all thanks to this twisty little puzzle. That’s pretty cool.

This Puzzle Solves Itself!

The slow, steady march of technological advancement in all fields continues to progress, and the world of puzzles is no exception. In previous blog posts, we’ve discussed not only technological leaps forward in making puzzles (like 3-D printers), but also new developments in solving puzzles.

We’ve joked that robots are coming for our puzzles, thanks to advanced machines and AI programs that can play games like chess, Go, and Scrabble on par with — and sometimes, far better than — human experts.

It’s the same with Rubik’s Cubes and other twisty puzzles. Even though speed solvers continue to break new ground in terms of sheer speed and efficiency, we can’t compete with robots that solve cubes in the blink of an eye.

And now, it seems we’ve reached the natural end of this journey…

A self-solving Rubik’s Cube.

Check it out:

The creation of a Japanese technician and self-styled “hardware hacker,” this Rubik’s Cube is the same size as the traditional cube, but the similarities end there.

Instead of the traditional plastic network of connections that allows you to twist and turn the cube every which way, this cube is packed to the gills with electronics, wiring, a series of motors, and the interconnected pieces that give the Rubik’s Cube its signature movement and flexibility.

A marvel of miniaturization and design, this self-solving Rubik’s Cube clearly has its own built-in solving algorithm. It doesn’t simply memorize the twists employed to scramble the cube and then reverse them; the solution and scrambling are completely different chains of events.

All in all, it’s a thoroughly impressive creation. Of course, if I’d known there were going to be self-solving Rubik’s Cubes, I wouldn’t have wasted so much time trying to solve one myself!

What Can YOU Solve In Under a Second?

Oh yes, it’s Rubik’s Cube time once again.

Every time I think I’ve seen everything someone can do with a Rubik’s Cube, a month or two later, another amazing video appears on the Internet, proving me wrong.

We’ve covered Rubik’s Cubes a lot on this blog. We’ve seen them solved underwater, while being juggled, during a skydive, and yes, we’ve seen them solved in increasing faster times.

As of last year, the record for a robot solving a Rubik’s Cube was .637 seconds. That robot, Sub1, has been the Guinness World Record holder ever since.

Until now, it seems.

That’s a right, a pair of engineers — Ben Katz and Jared Di Carlo — have nearly halved that world record with what they call their “Rubik’s Contraption.” This cube-solving bot posts a solving speed of .38 seconds.

Their machine is so fast that they had to program it to only allow one motor to move at a time. You see, in previous runs, more than one motor would try to move, and the cube would be RIPPED APART.

This lightning-fast robot is still waiting review by the team from Guinness, so, for now, Sub1’s record stands.

But for how long?
