Remotely Operated Underwater Vehicle

Hello Arduino community,
I am embarking on a journey to build an electrical system for a remotely operated vehicle. I will be using a Dual shock playstation shield connected to an ethernet shield and arduino uno. These three things will be on land. Connected to that will be an arduino uno, ethernet shield and an adafruit motor shield in the water. The adafruit shield will be hooked up to four dc motors and two servo motors. If anyone has any ideas about how my project will malfunction, please let me know. If there are things that you can help me with regarding coding, please help a brother out.
Best Regards,
Andrew Schussler

Do you plan of sending the video data over ethernet cable from the Arduino? I don’t think the arduino Uno is fast enough to do this, maybe using a seperate coax from the camera? If you plan on using a USB cable, think about the maximum lenght.

Hey johnyboy, I will not be running the camera through the ROV, only through the computer via a usb cord. Thanks for the help. Andrew

aschussler: how my project will malfunction,

If it will work on land the only serious issue will be water getting in through cable glands and along axles. These are not easy things to seal.

Are the motors driving propellers or wheels that run on the bottom of the pool?

If the device is floating the drag of the cables may overwhelm the thrust of the propellers. CAT5 cable is very stiff. Maybe use a different comms system that would work over lighter cables - perhaps light Coax such as you would use for stereo earphones. Might save the cost of Ethernet shields also.

Might even get away with using that light coax with the Ethernet shield. Although CAT5 has 4 twisted pairs, only two of those pairs is actually used. Furthermore, two of those could potentially be run together.

Makes my previous point, pointless :)
