Watch the video in the water.

This one uses a processor per segement and they are sort of networked, I would have thought the propeller could do the whole lot. That would be seriously amazing. My interest is in micro stuff so it would have to be micro servos, I've heard of those down to silly prices.

Wow!!! http://forums.parallax.com/images/smilies/freaked.gif For sure not a 'hobbyist' effort. Lots of shekels in such a project.

Amazing to see the swimming video. Now, if it could come out of the water on it's own. Interesting how many different robots the Japanese have funded. Glad to see so many into it, whether hobby or not.

Who says you have to have knowledge to use it?

I've killed a fly with my bare mind.

oh "quitcherwhining"

Back in my day, my "internet" connection was a 300 baud modem on my Commodore 64. :P

hehehe

I'm beginning to wish I hadn't posted the link.

Would anyone like me to post it to them on 3.5" floppies?

:) + as many winks as are needed not to cause offence :)

I remember those days. I can remember when Compuserve and AOL were new.

Those were the days.

Hey I could get 2 way sat.....I just hate to fork out the moola.

Then there was my first modem, an 80 baud acoustic coupled handset...

Anyway, on topic, it would be very interesting to put a camera in the nose of this, if it could handle any depth it would be a very useful tool...

It looks like it has a camera. There's a ring of LEDs in front, surrounding what looks like a lens.

Your right it does.

I'm wondering what the radio range is underwater.

I wondered about that, too. Maybe they just record the video for later playback.

How can we get some more details on this?

byond reading the webpage you could email them or try and track down any technical papers they have produced.

Many of the website references are in Japanese, but I am trying to get an English copy of the symposium papers. This would seem a natural for a Propeller application. I am not sure if the unit in the nose is a camera or a proximity detector. In the video it seems to avoid the bottom and walls of the pool using a sensor. If I learn any more, I will post to this thread.

I suspect it was not operating autonomously in the video and was backed away by the user. It is definatly a camera.

Another video here, shows the joint mechanisms, the camera and the mechanism to keep the camera level (I think)

A much better video, more details, thanks. It sure seems like a camera.

FYI - a radio controlled submarine that I saw in a hobby store about 2 years ago has a limit of 10 ft. The cheap subs only have a depth equal to the depth of the antenna.

That's still better than I expected. The video however is an interesting one, we can only assume its not 2.4Ghz or the poor thing would be cooked alive.
