Paper Tubes Make Stiff Origami Structures

Paper Tubes Make Stiff Origami Structures

Essentially, what is special is that we havea structure, configuration, that essentially is very flexible in one deformation mode, extremely flexible.

In the other modes, it's very stiff.

So, we have a paradoxical kind of structurethat is flexible and stiff at the same time.

We can tailor that flexibility and the stiffnessto do special movements, special configurations that allow us to have reconfiguration capability and adaptabilityof the structure at the same time.

We start with the basic miura strip.

Then we make two strips.

And then we put them together.

We glue them.

And then they will form a tube.

And what is beautiful about this is that wecan combine tubes with different angles.

Then we do the same thing, either with the same dihedral angle as theprevious one that I described or a different one.

And then we are going to couple them in thiszipper configuration.

And then we keep doing that.

And the creativity in the number of extractionsand solutions that you can come up with is endless.

It will be up to you on how you are goingto assemble this basic configuration.

It's a basic unit cell, the two tubes.

But how you combine them, that's up to you.

Then if you combine them in a certain way,you can do a bridge.

In a different way, you do a building.

In a different way, you do a robotic arm.

And so on and so forth.

What we did, I think, is just the beginning.

And we hope that other people can exploreapplications of these tubes in ways that we did not anticipate.
