Without external senses in a medium that's far more ... "Extra-dependent" upon the subject body the solution, or best available solution, would seem to be sensory, or best articulated sensory to the ends of determining metric of objective and subjective interchange, would be a machine learning or A.I. approach, particularly due to the unbelievable complexity of fluid dynamics, from what I've seen. The effect "on land" isn't so noticeable due to our relative slow movements in relation to friction influence from a physics perspective... Just my 2 cents anyway... Unbelievably important research towards the understanding of the "macro" microcosm though, or micro biological layer.

Well, if you keep manually actuating a servo then yes, they do tend to go bad.

This sort of Robotics enables biomechanical studies that would be practically and ethically impossible with real living creatures.
Le fyziks guise (1 month ago)
Projects like these need to prove that any removal, or lack of, features found in nature, will have a non-significant effect on their results. They're understanding how fish swim while a) having a hollow body b) cable connected c) limited flexibility compared to real fish. I doubt these can be safely ignored when implementing physical models to understand how fish swim.

Why is there no skin? Doesn't that totally change the hydrodynamics?
Dirty Robot (1 month ago)
You should pitch this as an autonomous device to collect plastic waste from the ocean. If they could collect the plastic and extrude more drones from them we would end up with a win/win situation. Sarc.

mig san (1 month ago)
for his applications he was talking about a torpedo drone would be better... fish seams pointless and over engineered
bokkenka (1 month ago)
When he said "drone", I wondered what's wrong with the current drone form? Underwater quad-copters should be way more maneuverable than a fish-drone.
Johan (1 month ago)
Lmao.
Far from acceptable. A baby can do that, without sensor you can not do anything, the simplest life being has them, and all that study about fishes and you haven't included fins? Why do you think fishes have them anyway?

The tether looks like it would interfere a lot with stabilization. Maybe it needs LASER power!

I'm not one to complain about free entertainment, but despite 5 minutes of talking, they didn't say much. Is there anything interesting happening in the field of bio mimicry? Perhaps something with neural networks?
David Sullivan (1 month ago)
kebakent the interesting thing about biomimicry is that it’s actually not that interesting from a CS standpoint. The programs can be super super simple and in many ways outperform a traditional bot. It would have been nice if the servo in the middle of this particular fish was working better. In the snake video, he talks about the “sidewinder” movement style, which is stable across different sand terrains. So because the movement is stable, you can greatly reduce the number of sensors, as well as the number/quality of processors running to calculate real-time corrections.

I imagine this kind of robot being great at underwater cave exploration. Being able to maneuver in tight spaces can be very handy.

Can't this be simulated? I mean, the drag from the cable must be larger than the inaccuracies you'd get modeling it in software right?
Brandon Walker (1 month ago)
They are doing this research at University of Akron. Probably just working with what they have.
Adam Harrington (1 month ago)
This is probably cheaper & faster. There'll almost certainly be some CFD involved when designing the body that fits around the skeleton but a simulation can only go so far.

I like the idea of robot fish, but I feel like accidental shark murder would become more of an issue than with the refrigerator robots.

An actual servofish! I can't wait to fish them with magnetic-pulse spears.
huldu (1 month ago)
I'm not impressed by the movement at all. It just looks very inefficient as a mechanical device. How about you spend the money you get on actually creating a cyborg fish, fish body and AI brain. Done.

Because he's studying fish movement???
Duane Degn (1 month ago)
In both the fish and the snake robot videos, I noticed they used AC to DC power supplies. Motors (like those in servos) don't always behave well with these sorts of power supplies. I often have much better luck with large LiPo batteries compared to bench top power supplies, when powering multiple servos. *Fun robot and video!*
MichaelKingsfordGray (1 month ago)
Then you are not using the power supplies correctly, or have poor ones.
Mike Moloch (1 month ago)
maybe adding a few fins would help stabilize things ;-)
The only fin that would do that would be dorsal fins. Though, they need to be able to extend and retract.
Loomy (1 month ago)
Very cool video! Would like to see more research projects like that!
Andreas Aristokrates (1 month ago)
It would have been only honest to talk about energy consumption and drag along the water. Drones under water seem to be really hard, air drones don't go kilometers away (solar ones yes, but there's no solar under water), but the ocean is really deep and you need to get close to stuff, to see it. And the snake man did disclose these issues, why not here...

What software do people use to design the physical body of something like this...? I'm in CS/EE so I never see this side of things. Is it ... solidworks or something?

I see Fusion360 being used by a lot of 3D printing YouTube channels. Adafruit (a great resource) has some Fusion360 tutorials.

I use OpenSCAD, it's been named the "programmer's CAD program". It's a wonderful piece of software. It doesn't have the features that AutoCAD or SolidWorks has, but it gets the job done

How do they want to make sure that the "fish" doesnt get accidentally(?) eaten by some larger fish?

Sometimes the little fish eats the big fish.

I think the fact it's swimming about in a paddling pool inside a lab helps ensure no other fish appear.

4:19-4:31 Why not just use mini submarines for that? What is the advantage of using a robot fish?
Alex Simpson (1 month ago)
+censacrof Haha, I could just imagine people believing that nature is always most optimal, and all cars having legs :)
Sam (1 month ago)
+huldu This would probably be primarily used by researchers to get footage of aquatic animals. I dont see much military need for this, as sonar is already a very effective tool for detecting objects, and I dont believe much fighting is done underwater. Also I have no idea how you could think a small remote controlled fish drone could be any where near the price of a submarine, or that it would make anywhere near as much noise as a propeller and a nuclear engine.
huldu (1 month ago)
This would cost even more than a tiny submarine. Also this one makes a lot of noise when moving unlike a small submarine which they can muffle quite well with the technology they have today. I'm sure in the future things like this will be better but, we have to get there first, maybe these guys will take the first few steps. You never know.
huldu (1 month ago)
They're just trying to find a niche to get money, possibly from the military in the future. It just looks so bad imo in the current form.

*_Does anyone know whether many AI researchers are tying their attempts to build AI to bodies that experience sensation?_* My concern is that the first generation of human level AI will be fundamentally sociopathic in the sense of being unable to experience empathy in the absence of being developed in tandem with a body through which it will gain the means to understand what it is to be human: to feel, to suffer injury, to feel empathy, to understand death.
