Homework

Now from the Boston Museum of Science, Sci-tech today on NECN.

You’ve heard about imitating life, but how about technology imitating biology? Joining us now from Museum of Science Boston is Casey Kute from Carnegie Mellon University in Piz burg.

-Hi, Casey.
-Hi, how are you?
-Good, good to have you with us. So you are looking to biology to design robots, and what’s specifically of your comeup with?

-If you look at the nature, you’ll see really unique abilities, one of them is gecko which is a small lizer that’s able to climb on smooth surfaces. So we want to go and figure out how is it doing that and take that same ability and those principles and use them on some of the robots we have. And one of them is Fober which I have here. And actually it uses a flag tacular last summer, which was our first step before beginning the s**, gecko fibers.

-And how does the gecko do what it does?
-So the gecko has tiny hairs on the feet and each one of those hairs can get really close contact with the wall. And the forces between the molicurs and both the fibers and the wall come together and what it called intimu?? forces, more specifically, the vendor wall’s forces. And if you get thousands of those tiny little hairs really close to each other, you can actually get the significant among the force.

-And what do you use to make the robot mimic how the gecko moves?
-So we use a p*** and molded some of these fibers, put them on one of our robots called wallbot and it actually can climb on really smooth surfaces. One of the problems that you have is that the ** between the fibers and ** is really strong which is great for climbing. When you want to move, you gotta a figure out the way to move it. So we actually peel from the surface and in the same way that the gecko peels its toes off.

-And so we are looking at some video here, this is wallbot.
-Yes, absolutely.
-So, it moves up the wall.
-Yeah, and so you see it as the f** coming off, it peels. This is slightly different from the gecko. Because the gecko actually is really soft at peels back and when we’re using more r** surface. But it tests same principles behind all the biological things.

-Pretty cool. What are some of the applications for this new technology?

-So one of those things we’ve wanted to do is take these really small robots and put them in so places we could do civilians and video monitory, you could put different pillows, you do sens** and temperature monitory and all kinds of things that move the se** around. It’s just really you expect.

-All ready and there are on display at the Museum of Science.
-Yep, they are. Come by and see them.
-All right, Casey Kute, thanks so much for joining us this morning.
-Thanks for having me.
-And you’ll be sure to join us every Thursday at this time for Sci-tech today or log on the Museum of Science website mos.org.
