The Robots That Swim Like Fish

as the man himself mentioned, the problem is connectivity and energy/space/pressure/moisture-constraints..its hard, thats probably why we know so very much less about the ocean.. i wished i was able to study marine engineering, i always dreamed about working on subs... :)

[@benjaminlynch9958]

Crazy to think how primitive all these robots are - the first ones are barely 30 years old and were made in the lifetime of most viewers. I imagine this is kind of what airplanes felt like in the 1920’s. If history is any guide, these aquatic drones are going to get A LOT better in the next 10-20 years.

[@ivancho5854]

As the First World War accelerated aircraft development, so the Ukraine war is accelerating drone development in the air and at sea. Future wars will contribute too. This will eventually result in improvements in civilian technology as with aviation post WW1 & 2. Interesting stuff. All the best. 🐟

[@josephyoung6749]

WWI saw many innovations, some of which spilled into peace-time, but human civilization will never be what it could have been were the World Wars averted. I know this sounds like a truism, but let me break it down further: It's simply impossible for us to recover ourselves, or imagine recovering ourselves, from something so titanically iniquitous as WORLD WAR, nor is it even possible to imagine a different outcome at this point. A climate of open-mindedness was emerging (at least in Europe) right before WWI that I fear we may never experience again as a species. There was an optimism at play at that point in history, culturally speaking, which would have been able to overcome all the vices we now associate with nihilism caused by constant warfare and maintenance of standing armies. The world would have continued to be multipolar, would have simply slowly moved away from colonialism. The concentration of power in the old nobility would have inevitably eroded, was already eroding, regardless of the World Wars, and even the human population might have grown at a slower rate, had there not been the threat and reality of so many of us dying in such a short amount of time due to not only conventional warfare, but nuclear warfare. Humanity lost about 100 million people due to these completely unnecessary wars, and several governments continue to argue that low birthrates are a threat threat to national security. I wish I could communicate what I mean. @@ivancho5854

@@josephyoung6749 Sadly everything you say is true. I have been all over Europe and today in every single country I see the scars of the First and Second World Wars and the Soviet occupation of Eastern Europe. The loss was unimaginable in scale and its impact continues. My mother had to be dug out of her house as a child and it is by sheer luck that I am able to converse with you now. A quarter of the men in my family died in WW1. Although they were not inevitable I think that biggest factor in Europe not continuing the pattern of the preceding centuries was the development of nuclear weapons, though that hasn't stopped war from returning to Europe in Ukraine. Unfortunately the devastation of cities there today is again unbelievable. Go in peace my friend Joseph.

At the 6:20 mark, I feel the vortices must both spin in the opposite direction for the fish to get a forward boost.

[@bubbasplants189]

water goes back, fish goes forward.

[@amkamath]

​ @bubbasplants189 instead of vortices let us imagine a pair of vertical rollers like a car wash. If they roll as shown, the fish will be sucked backwards. The fish could push the centers of the vortices backwards while getting an extra push from the rotation in the direction of motion.

[@cebo494]

To be fair, it's basically impossible to evolve something like a propeller in nature, and they do work pretty well for providing 1-dimensional thrust while also being relatively easy to design and construct. Evolution is very good at optimizing a system, but it doesn't create *the* optimal system. Fitness has to improve or at least stay roughly the same in an evolutionary system, so it gets stuck in local-maxima in the absence of environmental changes. It's the same as the classic "why haven't animals have evolved wheels" question. I could imagine a hybrid design being ideal instead, with a rear propeller for main thrust and fin-like structures on the sides, top, or bottom for maneuverability. There's no reason we can't have the best of all worlds.

[@ivancho5854]

I vaguely recall that nature has evolved a universal type joint which rotates under power at the microscopic level. Sorry that I can't remember more, I do know that when I read about it I was stunned at what I thought was impossible. All the best.

None of these types of fish "propulsion" is as effective as ship screw. It's the same case like by planes. Jet turbines are similar to ship screws. There is only one rotational movement along longitudal axis. No cyclic acceleration and decelation like by fish's fins. The only parts that wear out are bearings. Easy to maintain, easy to construct, lightweight. I do not see big reason of using of fish-like propulsion.

[@OzMat]

A robot battery powered fish if designed properly could be able to recharge its own batteries by anchoring itself into a water current by its nose/mouth /rod connected to internal motor/generator while body spins around it.😮 Just a thought, putting it out there. 😮

[@josephyoung6749]

Nature deals with matter at a 3d-spatial level in which every point (or part) of internal volume within the animal's body works in tandem with what we recognize as the external form of the fish, or rather, the outside surface of the fish's body, which is essentially a 2-D manifold embedded in what we consider a 3-D volume. The human mind deals with matter based largely on flat diagrams, or volumetric diagrams that have been unrolled onto a flat plane for visual identification. Because we only consider the outside form, all the gears and pullies and even the fixed components within the body of a robotic fish, while serving the function of producing a thrust by the flapping of a tail or fin, don't work together with the external form of the robot fish. For natural fish, both inside and outside bodily forms were developed in tandem over long-time. In a very real sense, the functional internal components of the robot fish conflict in many unforeseeable ways with the functions of the external form, such as flapping. The components of a fish's body will be even more difficult to replicate in a robot the more the living fish's center of gravity and general movement are informed by the *liquid* components of the fish's body, such as blood circulating with the fish's body. The physical characteristics of these innards are such that they include multiples states of matter (solid, liquid, gas) and mediate between them with varying degrees of softness and hardness within the fish's body (think "goo"). I imagine this could be overcome with math and AI basically, since these mediums are so abstract, and since their abstractness permits them to offer a vision of all 3-d Spatial points in tandem, as opposed to the limited manner in which human perception isolates shapes.

[@josephyoung6749]

Alongside computational models, there is also trial and error, the evolutionary process occurring over deep-time. This must in some way be reflected in the scientific method, in which it is possible to simply produce many, many variations of a form and test them out to see which ones are best. The problem with this is you could end up stuck in a local maximum of functionality and never reach the global maximum of whichever function is desired, forward locomotion being the function in question here with the robot fish. Neural nets could be capable, alongside other black-box tools, of accounting for this wholistic interpretation of functionality, by producing and testing models much faster than what we see over deep time with the evolution of various fish.

@Jon - I was surprised that Viktor Schauberger and his research on salmon propulsion did not get any coverage. Is he still considered too eccentric for the mainstream.

I was thinking about the examples over at Mothership Aeronautics, but utilising some of the bio mimetic propulsion methods mentioned by Jon. kzbin.info/www/bejne/n3bOnK2KYreDnLc Imagine a drone like this that uses flexibility rather than propellors, and looks like a whale, a trout or a manta.
