Knifefish sub

[mgwager]

Enough about that other narrator's voice already...

[bc71766]

ah very inefficient



[hadr0n]

William McGill is an oceanographer - A fine example of nominative determinism!

[CoolDJKool]

it could be used with a propelar

propelar for speed but the fins for sleath mode

[paparodius]

i liked ur idea

[Prestonboy13]

it looks slow

[macspectrum]

the navy would like a sub that moves thru the water without the signature sound of a propellor screw

[BLUFISH61]

creating a bi-linear wave action via a flexible membrane in water maybe should be done by utilising the water itself, a pump, some tubes and a series of open/close valves - perhaps? That rig sure looks as if it was funded by a fat grant from wealthy benefactor (or tax payers) What was the point of it again?

[lexmark136]

useless design, what a waste of time

[slessorpr]

This mode of propulsion cdn't be cilia!!

[mg2sna]

Dr. Bill McGill?

Not surprised.

[superdahoho]

energy and speed ratio will be very inefficient.

[MajorDiarriah]

I'm disappointed, I thought this would be about a knife nosed supercavitating fish robot.

[Saromatae]

Aha! If they want a design that doesn't get caught in weeds then they should make one that resembles a weed! Think about it.

Oh and the woman in the blue dress and short blonde hair looks like one of the Stepford Wives. Creepy.

[Johnnyboy2010]

haha that pretty blonde so didnt know what the fuck that guy was talking about hahahaha

[quietthomas]

That lady's voice makes me feel like I'm watching play school.

[Craydon]

Seems overbuilt.

[iurak6868]

and what benefits they get from that design?

is it more efficient?

does it make less noise than the actual propelers? (avoid being detected?)

[Dyzm]

It doesnt get caught in reeds and seaweed.

[marsCubed]

@iurak6868 they already told you why in the video. try listening. it is because propellers get caught in the leaves.

[iurak6868]

thank you,

I know now from the last reply to my comment

[zenith828]

waste of time... nothing to gain

[alexkidd3d]

awesome, the recent voiceovers have been so much better than that robot sounding lady.

[apyztd]

robobabe

[chakazul]

Nice blue dress! :P

[stigomaster]

McGill is just the perfect name for anyone wanting to make a fishbot.

[ShallowThoughts]

HeLLO NewBlondeScientist

[CredoVeritas]

This just looks like an expensive concept proving experiment that will be totally trashed for something completely different. I'm pretty sure I could have built this in my garage for 200 bucks to get the same results, but no, they had to use a 15lb motor driving 20 lbs of machined linkage to create this delicate wave.

All this knowing that flagellum type bots show the ultimate in propulsion simplicity.

At least he proved that his budget must remain high to meet his critical standards.

[TheManSand322]

--- Why is he talking to a Hooker

[vitruvian8807]

the more technology we have, the more we resort to nature design it seems.

[squidmanlol]

well, billions of years of evolution tends to know better than we do most of the time ; )

[Whats7His7Name7]

if you think that u just made some profound point about nature being better than technology, you are completely wrong. Nature just offers a tried and tested approach to success thanks to evolution.

[WHATFUCKLOL]

useless?

[MichelIchiy]

useless? Have u ever think about that in a near future we could make nanofishbots to swin through your veins and cure diseases? A blade propelled bot would propably harm your veins...so think about it before opening your mouth...

[WHATFUCKLOL]

okay. so can you also explain your nanofishbot engine? and after they cured my "diseases" how the fuck should they leave my body huh? low powered nanobots floating in my heart and you aren't calling it senseless? now think about that. DOC.

[MichelIchiy]

The research shown in the video has the purpose of finding the engine, then making it to nano (in a near future) is a matter of time. And how they are supposed to leave? LOL, man medic u have ppl that live with mechanical parts inside them, nano is a concept of a tiny tiny thing, so it won't be floating around, and probably you won't even notice. Nano things are made with molecules, very tiny parts. So make a research about nanotechnology to get good arguments first....

[WHATFUCKLOL]

i see... you are talking much but dont have any background knowledge...

make a research about accumulators and their seizings and then talk about your nano engine and of course i heard of nano technology... LOL

but if your so called "tiny tiny things" are in my circulatory means they are floating in it.!

nano your brain.

[MichelIchiy]

so if u know so much you know the potentiality of nanotechnology and the what nanobots will be able to do in a near future. If u heard of, u know about nanoengines and nanogears.What i'm sayign about that nanobots can search and cure for less invasive methods for curing cancer, rather and using quimo or radiation that harm the body so much...

[WHATFUCKLOL]

okay so you want to resell what? nano bullshit

[charlieclown]

they can put dampeners in the engine room and it will be like a stealth bomber.

[DeletedDelusion]

Reposting videos, are we?

[georgelpreput]

I really don't see this propulsion method outdoing propellers at speed or energy efficiency. Plus, that engine looks like it makes the craft really wobble a lot.

[GoreFienD]

put two "fins" sideways and you should get rid of wobling I think

[kittenclaws]

Just any two paired and working counter each other should do the trick-wave cancellation etc etc.

[AIWAC]

The point is to use it where propellers don't work.

[georgelpreput]

Where would that be? Even in shallow water, they still work.

[GoreFienD]

maybe in shallow rivers or marshlands. in places where vegetation could become stuck in propeler

[Spanky2k]

Woo! A decent narrator!

[Greywyn7]

Haha, about time.

[Zoiros85]

Hehe! Was thinking the same.

[noraui]

Why do so many people here act like such experts at this area.

[Maracachucho]

i'm a mechanical engineer student, and by the looks of it it seems like a pretty nifty design. i'd propose a more simplistic one though.

[madnessdexter]

how can you get more simpler then this?

[DidntKnowWhatToPut1]

this is nothing special

[comicus211]

Yes! Keep this narrator! She's better than the other one by FAR. thumbs up if you agree.

[Krashevil]

the new narrator looks hot

[HKragh]

not very impressed. seems very clumsy and the movement is kinda hardwired into the motor. Should have been made a lot more flexible with individual systems controlled by software. I'm sure the real deal can not only propel itself forward with this belly fin, but also steer, which will be close to impossible with the approach they have taken. Strange. Looks like something build in a garage, and not by scientists.

[rabbitsib]

This Idea is not new I have seen many scientist replicate fish in hopes of that fish to be the new propulsion under water but the flaw is obvious the amount of energy and parts involve to replicate each is too much which can lead to more problems in the end. "K.I.S.S."

[youstupidwoman]

after that l may be better calling it a Freudian slip,drive , l know I'v ran on less

[bloodaid]

oh my god thats such a horrible construction. it couldve been done so so soooo much better, I saw it immediately. but it doesnt matter right? 'cause I'm not the one making it

[princeofexcess]

legs are lame for transportation the only reason why we evolved legs is because we couldnt evolve wheels. Same thing with propellers they are great and fast and efficient ... why would we want less efficient ones.

[sausage4mash]

Not very impressed ,this could of been built 30yrs ago ! the orientals have synthetic muscles ,uk needs to up the budget on science big time

[bigsmatchy]

I like it when she touched it

[d3adp001]

these guys arent too smart, the crank limits the timing of the fin. They should use linear stepper motors at each location, and a microprocessor controller to establish timing. That way they can change everything in software. The fish has individual muscles, so mimic it properly.

[linqserver]

Yes You Are Right but dont forget the simpiest Solutions are the best.

[kettleschip]

man, you are so smart, you are so god damned smart you are a smartass who doesnt actually know how this was made!

[austpom333]

Would suite cargo liners as well, good woman also.

[TheDivineCellphone]

Not very impressive compared to the Japanese fish-bots and the snake in water...

[Paxmax]

I'm still waiting for organic engines run on glukose.

[1019drummer]

the undulating fin design is very cool........

[tristbjorn]

x-ray view? It's more like a look behind the cover -- which it is?

[snakedad]

Noticed that aswell.

[Uejji]

You're right. It's nothing like an x-ray view. This is more like if you pulled the skin and meat off of someone and said "Here is an x-ray view of this guy." No, you just took his outer layers off.

[1RadicalOne]

Imitating biology. One of the best sources of technology.

[monkeybike]

Dr William Me"Gill"

Good name for a guy that works with fish robots. :D

[blazednlovinit]

lol i thought that

[Docthewrench]

crankshafts  he doesnt even know he is using camshafts not crankshafts

[joshbradley1982]

It is a crankshaft because the "pistons" are connected to it - not a shaft with lobes on it that drive "pushrods" like in a camshaft

[reptilezsweden]

Just goes to show that knowing what things are called isn't necessary to make them work =) Schoolbook knowledge is a useless bitch =)

[AbsalomPitchingfork]

I love you.

[NikiDaDude]

It looks like a swimming camshaft.

[OntarioScienceCentre]

very cool.

[AntiCliche]

This would be freaking sweet! It'd have such a tiny sonic signature.

[barakuda1111]

That blonde on 1.25 was like duhhhhhhhhh :D

[xoANONiMUSox]

nature way is the best way !

[Shaunt1]

So it has a mechanical fin?

[eatyourteacher]

Does it also taste like fish? THAT would be awesome :)

[deadNIGHTCRAWLER]

no it wouldent, why would u want to eat it aneway?

[2014andBeyonD]

yes
