Interesting. I'm entering this competition next year. http://www.marinetech.org/rov_competition/
Well, I'm joining a group. They started making it, but they're about as electonic illiterate as you can get, so they're basically hiring me. Not really. It would be fun though.
This year I made a robot for Batelle, but I can't enter it in the National Robotics Competion, because I'm a bit late. Although I won 1st last year. Maybe I'll make something and enter it next year. The only issue is money.
