but who would want a swarm of cockroaches

Yet one of the greatest differences between natural and human technologies

Remarkably, cockroaches can self-stabilize

or give them a perturbation like an earthquake,

we discovered that their wonderfully tuned legs

They can go over complex terrain like grass,

they actually roll automatically to their side

to go through this artificial test bit of grass.

Robust systems can perform multiple tasks

in less than 150 milliseconds — you never see them —

using the same structures that they use to run, their legs.

very rapidly on rods, branches and wires,

and if you perturb one of those branches,

They have wings for flying when they get warm,

but they use those same wings to flip over

Robust systems are also fault tolerant and fail-safe.

without hardly slowing down. Extraordinary.

Here's an animal using a normal, alternating tripod:

but in nature, the insects often have lost their legs.

Here's one moving with two middle legs gone.

It can even lose three legs, in a tripod,

so they're actually really fast, when you see this.

Robust systems are also damage resistant.

It looks like a rapid, smooth, vertical climb,

They intentionally have a head-on collision with the wall

so they don't slow down and can transition up it

And they can do this in part because they have

And they're really just made up of compliant joints

Here's a dissection of an abdomen of a cockroach.

You see these plates, and you see the compliant membrane.

where you essentially origami the exoskeleton,

And you can do that now in less than 15 minutes.

and they're remarkably robust as a result

They're certainly incredibly damage resistant.

They even have some of the behaviors of the cockroaches.

So they can use their smart, compliant body

Now we want to know why they can go anywhere.
