Have we never talked about the uncanny valley on Science Buzz? I searched for the term, and got nothing. (Although… I’m beginning to suspect that my computer doesn’t accept voice commands. “Computer, display LOLcats,” gets me nothing, and I know that there are LOLcats out there.)

So… the uncanny valley. It has to do with robots, and human-simulation thingys. It’s like… like… well, here’s an example:

Think about factory assembly line robots—big arms, repetitive movements… it doesn’t do much for you, does it? They’re just boring ol’ machines.

Now think about R2D2, Star Wars’ trashcan robot. Beep beep, whistle! Cute, huh? He rolls around, and does sassy things we can’t understand, and we know he’s a robot, and he’s pretty likeable.

Now think about Johny 5 from Short Circuit. He can talk, he’s got a face, and expressive eye-flaps. And we still kind of like him, despite the attitude. (Great, you can read fast. Clean my kitchen before I have you recycled, robot.)

Now think abut C3PO, Star Wars’ deeply uncomfortable, shuffle-gaited robot. He’s pretty much human shaped, he speaks human (with an accent too…), and he’s clearly grappling with some of the same personal identity issues we real humans deal with. And… he’s just a little bit creepy, isn’t he? He’s like us, but not like us… How do we deal with this goldbot?*

And then there’s the “Simroid,” the Japanese robotic monstrosity used for dentist training. See the Simroid:

Clearly Lady Simroid has discovered what it means to be human, and she is, appropriately, horrified. And it doesn’t help that her existence is limited to sitting in a chair and having dental students see what hurts.

But, see, robots like the Simroid, in their appearance and limited behavior, are quite like humans. And it’s weird! They make us uncomfortable. So like us, but they’re absolutely missing the piece that makes a person a person. Brrrr

And then, moving on, we have healthy, living humans. Or maybe Blade Runner replicants. And they aren’t so weird any more. We’re back up to something we’re comfortable with.

It’s the Simroid point on this scale where the familiarity/comfort level takes a huge dive. That’s the uncanny valley.

(Another way to think about it might be cartoons. Stick figures. Disney’s Aladdin. Toy Story. The Polar Express movie adaptation. Pirates of the Caribbean. Which of these are you least likely to see on a poster in a kid’s bedroom? Well, maybe stick figures, but do you see what I’m getting at?)

There are different theories as to why objects in the uncanny valley creep us out so much. The remind us of dead things. (Like zombies!) They are similar enough to us that, on a biological level, we perceive them as a threat (because a genetically similar creature is more likely to pass diseases to us, I guess), and so we feel revulsion towards them. Or they’re no longer like robots, but when we judge them on the human scale, they come up disturbingly lacking. Basically, they’re weird.

So, when you’re building your humanoid, you have to decide early on where you’re going to shoot for on the uncanny valley scale. If you aim too high, you may end up dooming your creation to the same hate we have for ventriloquists’ dummies. (In my opinion, you should probably set your expectations somewhere around R2D2, unless you’re making a baby. And even then…)

Enter the military-funded “Battlefield Extraction-Assist Robot,” or BEAR. BEAR was designed to be able to rescue wounded people in combat areas, and to do heavy, potentially dangerous tasks. It’s basically some big treads and a torso with arms, and each new version is a little stronger, and more nimble and damage resistant. And the newest versions have bizarre teddy bear heads, apparently because that’s the sort of thing that’s reassuring to an injured soldier.

So where does this fall on the uncanny scale? We like teddy bears. But teddy bears are usually soft and fuzzy, not six-foot-tall human-torsoed robots, able to dead lift 500 pounds. Also, their dark lifeless eyes aren’t usually set in hard, urban camo faces. For me, at least, a face like that seems to promise physical dismemberment with utter, robotic detachment (pun intended, I guess?).

Am I alone? Am I relating too much (but not enough) to the BEAR? How do y’all feel? Anything else in the uncanny valley that you feel deserves a shout out for its creepiness? Let’s have it.

*I’m aware that R2D2 and C3PO are supposed to be spelled out phonetically. I won’t be doing that. Ever.
