提高英语听力能力 找对方法很重要!

Now from the Boston Museum of Science, Scientech today on NECN.
You've heard about imitated life, but how about technology imitating biology? Joining us now from Museum of Science Boston is Kathy Cue from Connell University in Pittsburgh. Hi, Kathy.

Hi, how are you?
Good. Good to have you with us. So you are looking to biology to design robots. And what's specifically you can come up with?
So, if you look at nature, you'll see really you need abilities, one of them is gecko, which is a small visitor that is able to climb on smooth surfaces. So we wanted to gonna figure out how it's doing that and take that same ability, and those principles and use them on some of robots that we have. And one of them is Forbot which I have here. And it actually use a flat tacky // which is our first step before being // synthetic--gecko fibras.  

And how does the gecko do what he does?
So the gecko has tiny heels on the feet. And each one of those heels can get very close contact with the wall. And the forces between the molecules, the fibras and the wall come together. And what called intimate forces more specifically the vanderwall forces. And if you get thousands of those tiny little heels really close to each other, you can actually get significant amount of force.

And then what to use to make the robot mimic how the gecko moves?
So we use a poler mimic tool and moded some of the fibras. Put them on our robots called Wallbot and it actually conquire really smooth sureface.One of the problems that you have is that the higent between fibras and walls is really strong which is great for requiring. But when you want to move you gonna figure out the way to move it. So we actually peel it from the surface and the same way that the gecko peels its toes off.

And so we looking at the video here, this is Wallbot?
Yes, absolutely.
So it moves up the wall.
Yeah, so you see as the feet coming off, it peels. This is by the way we get from gecko. Because the gecko has really soft toes and peels back, and when using more // surfaces. But it has the same principles behind the biological things.

Pretty cool. What are some of the applications for this new technology?
So one of the things we are wanting to do is taking really small robots and putting them in some places so we could do surveillance and video monitoring. You can put different pallows and do sensors and temperature monitoring, and all kinds of the things. Move the settings around which you really need gas backed.

Already. And there is the play and the museum of science?
Yeah. May I come by to see you?
All right. Kathy Cue, thanks so much joining us this morning.
Thanks for having me.
And you will be joining us every Thursday morning at this time for scientech today or log on the museum of science website mos.org
