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.

A Writing Prompt with a Puzzle/Game Twist!

I’m always on the hunt for different ways that puzzles have found their way into pop culture and society in general, and it never ceases to amaze me how ubiquitous puzzles can be.

I recently stumbled across a puzzly reference in a list of writing prompts intended to spark some creative scribbling:

A long while back, the world came to an end, and with it your favourite newspaper. For years you’ve been filling the idle hours between scrounging and scavenging by solving crosswords puzzles. You’ve got 50 years worth of backlogs, but now you’ve completed every single one.

Every single one except the most recent one. The final one, that is. The crossword puzzle that never got released because the world ended.

So now you’re on a journey through the post-apocalyptic wasteland to find the last puzzle, and finally complete your collection.

A dystopian tale with a puzzly hook? Sounds like a can’t-miss YA book to me!

It’s an intriguing pitch — for a story or a roleplaying campaign — and one that reminds me of David Steinberg and the Pre-Shortzian Puzzle Project, as they’re still on the hunt for 142 missing New York Times crosswords that weren’t published in New York.

And, naturally, since my mind has wandered to puzzle-and-game-fueled scribblings, I simply must include this board game-inspired take on the classic Abbott and Costello routine “Who’s on First?” that a friend of mine penned. Enjoy!

Customer: Excuse me, do you sell this particular board game whose name I’ve forgotten, it’s like Parcheesi, only smaller and has a Pop-O-Matic dice rolling bubble in the middle.

Clerk: Are you looking for Trouble?

Customer: What? No! Sorry.

Clerk: Ah, we do have that. But without the dice popper.

Customer: What?

Clerk: Sorry.

Customer: No, it’s fine. I just want your opinion of the other game you have, if it’s no trouble.

Clerk: Well, it kind of is. According to some people.

Customer: Sorry?

Clerk: Yes.

Customer: You are fast becoming a source of aggravation.

Clerk: Oh, we have that one, too!

Customer: Argh! What. Game. Were you talking about before, and what’s your opinion?

Clerk: Sorry, and it’s no Trouble, if you ask me.

Customer: Well, great.

Clerk: So do you want that?

Customer: Huh?

Clerk: Or would you prefer Aggravation?

Customer: I’d rather you gave me a clue!

Clerk: Well that game’s nothing like Parcheesi.

Customer: Then why bring it up?

Clerk: I didn’t, you did!

Customer: Look, just… go.

Clerk: We don’t have that, but what about Othello?

Customer: ARGH!


As always, puzzles and games make everything better.

The Diabolical Art of Bar Bets

We discuss all sorts of time-honored puzzles and brain teasers here on the blog, but it’s not often that those discussions wander into the arena known as bar bets.

Simply put, bar bets are contests between two parties wherein money or free drinks are wagered on one’s ability to accomplish a given task. Sometimes, that task is answering a bit of trivia, or engaging in a feat of strength.

But more often than not, bar bets are brain teasers designed to separate a fool from his money.

And if you approach them like brain teasers, you have a better chance of holding onto your hard-earned dough.

You see, many of these bar bets are designed more like carnival games than fair wagers; there’s usually a trick involved, and your opponent is wagering on you playing by the rules, rather than out-thinking the game itself.

Example: the wager seems simple. There is a drink placed completely beneath a hat. You must drink the drink without touching the hat.

It seems impossible, but that’s where you must get creative. You can crouch down near the hat and make a slurping noise, and then declare that you’ve succeeded in drinking the drink. Your curious opponent is forced to lift the hat to check, and at that moment, grab the drink, down it, and you’ve won.

You adhered to the letter of the wager, but not the spirit. But that’s the name of the game.

Be careful, because some bar bets are based solely on wordplay.

Example: Tell your opponent to get a coin out of their pocket and set it under a drink coaster, ensuring that you don’t see it. The wager? That you’ll be able to tell them the date.

As you wave your hand over the coaster, as if doing a magic trick, simply announce today’s date. After all, you weren’t specific. You just said you’d tell them the date, not necessarily the date on the coin.

A similar one involves wagering that you can stay underwater for any particular length of time. Once you make the wager, simply hold a glass of water over your head for that amount of time.

A little cheap? Sure. But hey, a bar bet is a bet. And the devil is in the details.

Some bar bets, though, come down to technique. You present a seemingly impossible task, and then accomplish it in a clever way.

For example, my favorite bar bet: You have a glass (a wine glass, a shot glass, whatever), with a coaster (or business card) on top of it. Atop the coaster is a cigarette, standing on end. And atop the cigarette is a coin.

The wager? Put the coin into the glass without touching the glass, coaster, cigarette, or coin.

There’s no wordplay, no trickery, and no deceit here. This one is all about gravity.

You see, the coaster and the cigarette are light, while the coin is not. If you crouch down below the glass and blow upward, you’ll be able to push aside the coaster and cigarette, leaving the coin to fall straight down into the now-open glass.

Easy. Once you know how it’s done, that is.

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!
