Origami robots that reshape and transform themselves

As a roboticist,
I get asked a lot of questions.

"When we will they start
serving me breakfast?"

So I thought the future of robotics
would be looking more like us.

I thought they would look like me,

so that I built eyes
that would simulate my eyes,

I built fingers that are dextrous enough
to serve me baseballs.

Classical robots like this are built

and can function based on
the fixed number of joints and actuators,

and this means their
functionality and shape

are already fixed at the moment
of their conception.

So even though this arm
has really nice throw,

to even hit the tripod at the end,

it's not meant for cooking you
breakfast per se.

It's not really suited for scrambled eggs.

So this was when I was hit
by a new vision of future robotics:

the transformers.

They drive, they run, they fly

all depending on the ever-changing
new environment and task at hand.

To make this a reality,

you really have to rethink
how robots are designed.

So imagine a robotic module
in a polygon shape

and using that simple polygon shape
to reconstruct multiple different forms

to create a new form of robot
for different tasks.

In CG, computer graphics,
it's not only news,

it's been done for a while, and that's how
most of the movies are made.

But if you're trying to make a robot
that's physically moving,

it's a completely new story.

It's a completely new paradigm.

But you've all done this.

Who hasn't made a paper airplane,
paper boat, paper crane.

Origami is a versatile
platform for designers.

From a single sheet of paper,
you can make multiple shapes,

and if you don't like it,
you unfold and fold back again.

Any 3D form can be made
from 2D surfaces by folding,

and this is proven mathematically.

And imagine if you were to have
an intelligent sheet

that can self-fold into any form it wants

anytime.

And that's what I've been working on,

and I call this robotic origami

"robogami."

This is our first robogami transformation

that was made by me about 10 years ago.

From a flat-sheeted robot,

it turns into a pyramid
and back into a flat sheet

and into a space shuttle.

Quite cute.

Ten years later, with my group
of ninja origami robotic researchers,

and there about 22 of them right now,

we have a new generation of robogamis,

and they're a little more effective
and we do more than that.

So the new generation of robogamis
actually serve a purpose.

For example, this one actually navigates
through different terrains autonomously.

So when it's a dry
and flat land, it crawls.

And if it meets some rough terrain,
it starts rolling.

It does this, it's the same robot,

but depending on which terrain it meets,

it activates a different sequence
of actuators that's on board.

And once it meets and obstacle,
it jumps over it.

It does this by storing energy
in each of its legs

and releasing it and catapulting
like a slingshot.

And it even does gymastics.

Yay.

So I just showed you
what a single robogami can do.

Imagine what they can do as a group.

They can join forces to tackle
more complex tasks.

Each module either active or passive,

we can assemble them
to create different shapes.

Not only that, by controlling
the folding joints, we are able

to create and attack different tasks.

The form is making new task space.

And this time, what is most
important is the assembly.

They need to autonomously
find each other in a different space,

attach and detach depending on
the environment and task.

And we can do this now.

So what's next?

Our imagination.

So this is a simulation of what
you can achieve with this type of module.

So we decided that we were going
to have a four-legged crawler

turning into a little dog
and making small gaits.

With the same module, we can actually
make it do something else:

a manipulator, a typical
classic robot task.

So with a manipulator,
it can pick an object.

Of course, you can add more modules
to make the manipulator legs longer,

to attack or pick up
objects that are bigger or smaller,

or even have a third arm.

For robogamis, there's no
one fix shape nor task.

They can transform into anything
anywhere anytime.

So how do you make them?

The biggest technical challenge
of robogami is keeping them super-thin,

flexible, but still remaining functional.

They're composed of multiple layers
of circuits, motors,

micro-controllers and sensors,
all in the single body,

and when you control
individual folding joints,

you'll be able to achieve
soft motions like that

upon your command.

Instead of being a single robot that is
specifically made for a single task,

robogamis are optimized
to do multi-tasks,

and this is quite important

for the difficult and unique
environments on the Earth

as well as in space.
