Let's Make Robots!

NURC National Underwater Robotics Challenge entry from Carl Hayden H.S.

It is teleoperated from the surface while it goes under water

Here is an ROV built for the National Underwater Robotics Challenge. This video clip shows the mission and then shows one of the teams, Carl hayden High School, Falcon Roboitics team's ROV, Amanda going through its mission at 4 x the speed. You can learn more about this competition at www.h2orobots.org

Students at the school spen three months designing and building this rov based on the legacy knowledge from the four years prior experience.for pictures of the construction

Way cool! First submergable on LMR! Nice!!

- And it looks like good fun too. Whish my HS was that fun!

Love to see some pictures of the thing to really understand it..

Here is the lnik to see more pictures during the construction

Impressive!

All in silecone, new challenges for a robot..

What is this:

DSC04653.JPG

It is a 36 LED cluster encased in clear resin like thise used in ecasing spiders  or models. There is a PVC sleeve in the back that is filled with 3M Scotch Cast, it is a black liguid rubber mix that is in two parts initially but can be mixed and then it becomes solid rubber in 30 min. We embeded a Subconn  wetmateable connector in the PVC while we poured the Scitch Cast in so we can replace by connecting and disconnecting it.We use LED light becauseof the low power consumption and because of the nature of the light it produces. It is great for underwater cameras. Too much light and harsh light like incandecents are no good due to the "hot spots" they create. The LED create more of an ambient light. 

I guess I should put a few more links to these items on the post. I will do that soon. Thanks again for letting us post. 

The silcone you see is just in case the Scootch Cast pulled away from the PVC. Insurance!

I wonder if we could make one for under $200.
There are some that come close!

We helped to develop tyhe ROV in A Box for Inventivity.com

There is also another site that has plans and ideas for inexpensive rovs

Hope that helps!

OKay. That's me sorted for my next project.
Great we should see you next year at NURC in AZ in June! www.h2orobots.org
I'd be there in a shot, but the flights would cost more than my robot!!!!
thats soooo expensive
