THESE ARE A FEW OF MY FAVOURITE THINGS

OBJECT(s) OF THE WEEK

BY: ROWENA MCGOWAN

It’s that time of the year. I, too, am graduating and moving on from Musings. Unfortunately for me, I haven’t come close to running out of objects to rant about. So I thought I’d change up the formula and talk a bit about several of the objects I love but ran out of time to devote a full column to. So, without further ado:

Robovie

We’ve thought a lot about the industrial and economic consequences of an increasingly automated world but what about the cultural ones? How will people relate to the robots who are probably in our very near future? Is our robotic world going to be more I, Robot or Terminator?

Robovie was part of an experiment to determine how children (ages 9, 12 and 15) reacted to a robot which acts like a human and in particular, how they reacted to a perceived injustice being done to that robot (although Robovie was not technically a robot, since it was actually controlled by a technician in another room).

Each child interacted individually with Robovie. Robovie showed them an aquarium, taught them about the ocean, asked them for a hug and played ‘I Spy’ with them. During Robovie’s turn to guess, a technician would come in and tell Robovie that it was time to get into the closet. Robovie would respond that it was unfair to make him go into the closet before the game finished and that he was frightened.



Afterwards, the children were given a questionnaire to see what their opinions of Robovie were. Over 2/3 of the children were willing to be friends with Robovie but only a little over half of them thought that it was wrong to put Robovie in the closet (compared to putting a person in the closet, which almost all of them thought was wrong).

As robots become more advanced, we’re going to have to grapple with how we treat them and eventually, perhaps, what it means to be human. As for me, I got upset just watching the video!

The Great Omar

Sorry to any bibliophiles that I just made cry by reminding them of this book. The Rubáiyát of Omar Khayyám is actually the name given to a collection of poems written by Omar Khayyám, a Persian poet, astronomer and mathematician, and first translated by Edward Fitzgerald.

In the early twentieth century, Sangorsky and Sutcliffe, a British bookbinding company, were commissioned to bind a copy of The Rubáiyát of Omar Khayyám, money no object. The spectacularly beautiful final product was called The Great Omar.

In 1912, the book was sold to an American collector. Since the book was so valuable, they sent it over on the safest ship available at the time.

Yeah. That didn’t go so well. The book has never been found but the legend of the ‘priceless book’ lost on the Titanic lives on.

Not the quitting type, Sutcliffe created a second version of The Great Omar and, taking no chances, it was locked in a bank vault for safekeeping. The vault was subsequently bombed to smithereens in World War II, because some objects can’t get a break.

A third copy is currently resting in the British Library. If I was them, I would be very, very nervous.

Apatosaurus tail

If I had any Photoshop skills whatsoever, I would put an Indiana Jones hat on an Apatosaurus. Why? Well, partially because I have an extremely weird sense of humour but mostly because, like Indy, the Apatosaurus was a master of the whip.

Recent research has suggested that Apatosaurus and its relatives could crack its tail hard enough to break the sound barrier, much like a bullwhip.

The evidence comes from tail vertebrae. Tails have been found with fusions of the bones between the thick, muscular section and the thin, flexible part. These kinds of fusions are often caused by stress – like the stress of being repeatedly cracked. Recently, paleontologists have built and tested a model of the tail, which proves that such a whip crack was physically possible.

 Why did an Apatosaurus need a whip? Probably not to fight Nazis. The latest theory is that they used them for communication and especially courtship.

Shiri

No, this hasn’t become a porn blog. Shiri is a robot (yes, I’m having two robots. It’s my swansong and I like robots). Shiri was created by the University of Electro-Communications in Tokyo and responds to stimuli in the same way a human would. When touched unexpectedly, it flinches. When struck, it clenches.



But what’s the point of making a robot butt? It’s not the reason you’re thinking! Shiri is actually an innovation in expressing sensation organically. The hope is that through Shiri, researchers will eventually be able to create a robot which responds exactly like a human. Freaky? Yes. But a robot that behaves like a human is also easier for a human to interpret and understand.


And that’s it for me! Thanks, everyone, it’s been a treat. And, when things get tough, remember:

THIS IS THE DROID WE'RE LOOKING FOR

OBJECT OF THE WEEK

BY: ROWENA MCGOWAN

Last year, a little movie came out that you might have heard of.

You know, if you were really paying attention, you might have caught a whisper. Source.

I jest, of course. Disney’s marketing kicked into high gear last year to make sure that everyone was excited about the new Star Wars movie. A lot of the marketing focused on BB-8, the adorable new droid starring in the film, who premiered in the first teaser released in November 2014.

 Of course, people got excited about BB-8. Somehow, the filmmakers had made a droid even cuter than R2-D2. And BB-8 had a cool, if apparently impractical, design. BB-8’s lower body is a sphere, the head a small dome perched on top. As the body rolls, the head stays perfectly in place. It was a pretty weird design but hey, with CGI you can produce anything, no matter how physically impossible, so people were mostly nonplussed.

Then, during the Star Wars Celebration 2015, BB-8 rolled out on stage.

People went nuts. It had actually already been confirmed, in December 2014, that BB-8 was a physical prop but I don’t think people were really expecting it to actually be able to move autonomously. Somehow, this weird little thing could move, look around and interact with the world without its head falling off. The Internet being the Internet, the race was on to figure out how BB-8 works.

With all of nerddom bent on solving this problem, we must know by now, right? Not so much. Disney has never confirmed exactly how BB-8 works so we’re still just guessing.

People pretty quickly connected BB-8 with the Sphero, another spherical rolling robot. This seemed like a pretty safe guess, since Disney had actually contributed funds to start the company behind it. However, Sphero didn’t have a head on top, which is the truly amazing part of BB-8, and Lucasfilm released a statement saying that, in fact, Sphero’s mechanism was not used because it didn’t produce the expressiveness that BB-8 demanded.

So, how does BB-8 work? Magic? Giant hamster ball? (Don’t laugh, it was suggested!). The best guess comes from howbb8works.com, which is run by Carlos Sánchez and Emilio Gelardo.

They discovered a patent filed by Disney for a magnetic spherical balancing robot drive. One of the descriptions pretty closely matches BB-8. The body rolls using omni wheels (wheels which can roll in any direction) and relies on accelerometers and gyroscopes to know its position in space. The body also has a mast inside, which swivels around as the body moves so the head can reposition itself (for a video of how it works, click here). How does the head stick to the mast? That’s still the biggest question but the general consensus is magnets.

This is all very cool but is all this pop culture and techy stuff really relevant to the museum world? I think so. Museums are unique because of their focus on objects but lately, especially with the rise of digitization, we’ve been wondering how much the physical object really matters. Can people form the same connection from just looking at a picture or a digital model?

I think BB-8 and the broader Star Wars movie proves how much the object still matters. It would have been far easier for the filmmakers to just use CGI to create BB-8, just as it would have been easier for them to skip many of the physical effects they used. But they didn’t. They took the time to make a functioning prop. They played with it. They innovated. They poured their hearts and souls into BB-8. And people responded. They got excited. They got curious. They started theorizing how it worked and sharing ideas. They researched. They built websites. They built working models. None of that would have happened if BB-8 had been just a collection of pixels on a screen.

CGI creates marvels. But objects, physical objects, still have the ability to connect with people in a special way. BB-8 would always have been cute. But the magic happened when we found out it was real.

Also, when tired MMSt students misspoke the name. That was pretty magical, too. Credit: Olivia Gawron
