More information please!
i need to design an underwater robot that can be swim like a fish in the water. So, i need to know what is the main points that can help me to design it and what is the main component that i can used.
-
The best thing to do is an internet search and see how other people have done it.
Here is my robot fish:

Now,
The first thing you need to know is how YOU define an underwater robot.
For instance it could be an autonomous pool cleaner or a robot submarine that could figure the depth of the water body or pool by SONAR.
For a beginner like me an underwater robot would be something that just manages to move around.....
If I were you, my basic idea would be to build a waterproof box sealed tightly with a shaft/turbine coming out....you know like a ship....
and for the turbine to move, connect a powerful servo inside the box to a metal rod......YOU GET THE IDEA!
So if you agree with me try the following links out-
1. http://in.youtube.com/watch?v=nS8iZ7ns2i4 - Just an example of an underwater squid robot.
2. http://adventure.howstuffworks.com/cruise-ship3.htm -How Ships Move(I don't think you'll need this... but anyway)

^ :D simplicity FTW~! ^ "K.I.S.S." ;)
You could also use a PVC pipe with threaded endcaps, and ready made and/or home made gasket for water tightnets. If you go the home made route, use CLEAR silicon or RTV sealer, as it is durable, saltwater resistant, and its most important quality - just flexible enough to provide a reliable seal. When starting out with underwater robots, PVC plumming stuffs are your friend. They are cheap, reliable, and versatile. Also keep in mind to take your time; Dont just build the container and stick the electronics in it with out testing every component separately, to see if they perform their function, first. Lastly, be conscious of the materials and physics of what you are working with... water's eagerness to come and check out the inside your bot increases exponentially along with dept. :D

The problem with this project is that a fish is such a unique creature in the way it moves. If I were to do it and if I wasn't that experienced I think I would get a propeller propollusion kit or two and use that and just make my robot look like a fish. Whatever you do the key here is going to be that it is waterproof.
And one more thing what are you building it out of?
Good luck!

Do you have to control its height and use RC???
There are many RC forums here....use one of those if you do.

How about magnetohydrodynamics propulsion systems? http://www.skewsme.com/mhd.html
It sounds like a very interesting concept, although probably not so efficient.
I did try to make a very simple proof of concept experiment a few years back, but the electricity flowing through the water separated the H and O molecules (electrolysis) instead of propulsing it :(
Have anybody else tried it before?

Did you try cooling your coils with liquid helium to 452.13° till the coils provided little next to no electrical resistance? ... ... ...
