Yeah, right now, it doesn't even have the googly eyes on it.

So I think that's probably Steven.

How I'm 1/4 year PhD student in the bio mimicry program, and I study fish biomechanics.

So I'm interested in how they move on and how their body movements relate to their total body.

So this is our fish robot.

It's, ah, robotic platform that we used to answer questions about official promotion that we can't with life.

Fish cause robots do what you want.

Where is the animal?

Doesn't always do what you ask it to.

And so, um, the robot actually provides this interesting set of circumstances.

We can change the shape of the robot independent of the motions of the body makes.

So if I'm studying eels and tuna, I can't tell the hell Would you mind something like a tuna for me And vice versa.

Wears with the robot.

We can make this shaped like a tuna and say robot, please swim like an eel.

Theo.

Yeah, Robot is pretty simple.

It's five servo motors connected through an artery.

No.

And then we use the Arduino program.

Thio run the robot, and the program that we've written allows us to program, uh, straight swimming, but also interject turns whenever we want on.

This is based on some of my earlier research with fish, and I'm understanding how they control their pulses.

Tether.

It's like taking for war.

So, yeah, there's no sensors or anything in here deciding when it should turn.

It's just a pre programmed algorithm, and, um, I used the tether kind of as a leash to reset the system.

Looks like we have a motor not behaving everything on this robot save the motors and the wires is three printed.

So that flexible tail you see, we printed in our machine in the back and these body shells, we copied the morphology of an actual fish.

So this is based on a giant Daniel, which is the larger cousin of the zebra fish that you see in the pet shop all the time.

We can make this shape like anything are, um, future research is going to involve looking at how increasing body depth changes the maneuverability.

So think about plate shaped fish like a discus or my place or escape toe well places and skates are interesting because they've turned their heads to the side, and so they look like they're top to bottom.

But they do swim like a laterally compressed fish.

But I think more like tangs like Dori.

I'm trying to see what mother.

This is not just unplug it.

Complaining?

Yeah.

No, that didn't drop the amperage.

Okay, there's a few different applications, mainly opportunities for underwater reconnaissance.

It could be applied to mean the Navy would be interested in things like this, but so would, uh, oil rig inspections as well as dams and bridges.

Most often, the robots they're using right now are shaped like refrigerators and have about six squirt guns pointing off several different directions.

And so you can imagine, Jet.

Yeah, you've got a very unhygienic dynamic shape that's very unstable.

A match with the very complicated control scheme.

And so you lose these things all the time, and they're like, $5 million apiece.

So if you have a control scheme that's more robust, but it's still just as maneuverable.

You can potentially not lose things nearly as often s.

Oh, yeah, yeah, but the other thing is like just underwater exploration in general, like weaken scuba dive and free divers can dive down in like 500 feet.

But they can only be down there for 32 40 minutes, depending on the circumstances.

And so because of that, we know almost nothing about what's happening underwater.

Ultimately, it would be good if we can spend a whole lot more time underwater and drones like this.

They're going to be important for being able to expand our capabilities in that round.

So a single wave, we're working on more complex implementations, and finally, it can even perform something called concertina locomotion.

And so once it gets to that point, it'll finish a cycle.

So this is what they do inside of a tunnel.

If it hit the tunnel wall, it would be detecting that.
