Adverbs of degree

It's clearly robotic and also, well very human like the uncanny valley when something artificial triggers a feeling which can go from super cute, super creepy happens in an instant.

Adverbs of manner

But there are actually two in candy valleys, one static and one for motion.

And this team of designers and roboticists think they figured out how to avoid the fall.

We have this really strong notion of biological motion.

So you very, very rarely mistake a machine for a living thing.

So what is it about the way that a machine moves that will make you believe in it as if it's a live wire talk with Will Jackson founder and Ceo of engineered arts to understand how they design prototype and test their humanoid robots, cracking the code of dynamic movement has been a continuous journey of prototypes and designs for engineered arts.

Amica is their latest instead of being sort of photo realistic.

We're more concerned about what is the essence of being human.

And it's not just visual, it's this dynamic data, it's this movement data.

Um, so we have uh changing the expression so the focus of the eyes comes in tighter.

I think we went through 10 different attempts of getting a smile and it was just trying to get the crease in the, in the skin when when the robot smiles.

So we ended up having to add various fibers and parts that with tension the skin inside.

Part of what the programmers here are doing is they're studying people and looking at how people behave and how can we can mimic these kind of behaviors?

So if the robot behaves and the way you expect and it makes expressions that you understand, you can do a lot of powerful communication with that.

You know, you go to the cinema and you don't look at the screen and say, oh look some red pixels and some blue pixels you immerse into it and you become part of that story.

What we're doing is taking that kind of willing suspension of disbelief and putting it into the physical world.

America is a communication robot built to entertain and educate engineered arts, focuses on designing the gestures.

Look and movement of the robotic systems.

They leave the Ai and what's being said to the universities and companies that buy them each unit takes about 12 to 16 weeks to make and cost between 125 $100,000.

The first thing you learn is that you're never going to match human.

So the first thing you learn is how to deal with disappointment.

And so we were trying to mimic the way that human vertebrae worked and then these red cords here are like the muscles, there were six motors on this as well.

So enormously big and bulky problem is that we have these incredibly effective actuators.

Human muscle has this huge power density and very, very fine force control.

This one in front of me is a version two.

So one paper this looked kind of cool and I drew it all out and I came back into work and I thought with a mechanical design team and said hey guys can you turn this into reality?

And then we realized there was so much friction in all of this complexity in all of this kind of cable drive in here that just all the power of the motors was lost in this drive.

So I spent maybe three or four months just working on this and then you just at the end of it, it's just like, wow doesn't work at all.

I think we actually went through seven different versions by the time we got to this when we dropped the idea of having seven vertebrae because we realized you couldn't actually see it.

But human movement isn't just affected by how our bones, joints and muscles move together, but also by the movement of our skin.

You have 45 I think it is different facial action units that you can do.

So it's everything from a little tiny muscle pool in here to your inner browse, middle brows out of browse mouth corners, how do they transition from into a smile and then back into a neutral expression.

So we did a lot of work actually studying human faces to these faces are made of silicone.

So we end up having to put all kinds of fibers and fabric and things inside that gave it some more strength.

The head is actually used up with the motors for driving the face and then we try to make the skin as Then as we can so it goes down to about one thick.

Their models are all made in house allowing ideas to go quickly from design to production.

They categorize and record every part they make if something doesn't work now it may work later.

America is built on the years of learning and design from earlier models.

So robo thespian was our first kind of robot that was a hybrid pneumatic electric robot which is quite an unusual design.

We were really interested how can we make a compliant robot?

How can we make a robot that's safe around people?

We did that with the early ones by using pneumatic, so air is compressible whereas highly geared motors, you can't really back drive them.

You'll notice some of the motion is quite jerky, it's a little bit clunky.

There is actually a very small compressor inside America which is used for the arm balance mechanism.

So the air is used more like a spring within the system.

This is definitely something we discovered with robo thespian, you know, 15 year old robot that using this hybrid pneumatic electric approach could be really efficient.

He's a Mesmer type robot which means he's got natural skin actually touching his face.

Every little piece of hair on his face is inserted manually.

Even his wobbly little he's gonna punch me.

It's a very very different aesthetic to America.

So amica we wanted to make robot as robot.

No pretense that it's human and we were more concerned about the movement with the measurement type robots they made to have a more human look.

So we've got this soft skin and you see all these wrinkles on the hands.

The team is still fine tuning its design and functionality with plans to perfect its hands dexterity.

 So all these subtle things come and kind of mean that thing doesn't work.
