Homework
Now, from the Boston museum of science, Si-tech Today, on * CN.
You've heard robot imitating life, but how about technology imitating biology? Join us now from museum of science. Boston is Casey Kute from Carnegie Mellon University
Hi, Casey.
Hi, how are you?
Good, glad to have you with us. So, you're looking to biology to design robots, and what specifically  have you come up with?
So, if you look at nature, you'll see really unique abilities. One of them is the gecko, which is a small lizard that's able to climb on smooth surfaces. So, we want to go and figure out how it is  doing that. And take that the same ability, and those principles, and use them on some of the robots that we have and one of them is Folbar, which I have here. And it actually uses a flat * which is our first step before beginning the synthetic gecko fibers.
And how does the gecko do what he does ?
So, the gecko has tiny hairs on the feet, and each of those hairs can get very close contact with the wall. And the forces between the molecules, and both the fibers and the wall come together under what are called intermolecular forces, more specifically the Van der Waals' forces. And if you get thousands of those tiny hairs really close to each other, you can actually get a significant amount of force.
And what do you use to make the robot mimic how the gecko moves?
So we use a polymer material and molded some of these fibers, put them on one of our robots called wallbots and it actually can climb on really smooth surfaces. One of the problem that you have is that the adhesion between the fibers and the wall is really strong which is great for climbing. But when you want it to move, you've got to figure out the way to move it. So, we actually peel from the surface, and in the same way that the gecko peels its tones off.
And so we are looking at some videos here, this is robot.
Yes, absolutely.
So it moves up the wall.
Yap, you'll see as the feet coming off, it's peels it's slightly different from the gecko ,because the gecko actually has really soft toes and it peels back when we are using more rigid surfaces. But it has the same principles behind all the biological things.
Pretty cool, what are some of the applications for this new technology?
So one of the things that we want to do is to take this really small robot and put it in such place that we could do surveilance and video monitoring. you can put different pillows, the sensors and temperature monitor  and all kinds of these things that moves the sensors around. It is really our expect.
All that is on the display on the museum of science.
Yap, we are. Come on and see you.
All right, Cesy. Thanks for joining us this morning.
Thanks for having me.
Wish you join us every Thursday morning at this time for Si-tech Today or log on the museum of science web set at os.oak.
