homebrew idea

I like to have a challenge for my students students each year and I have been waiting for this one for a while. I wanted something different to try and get some ideas about Robotics happening and came across this 3 years ago now. It is a Homebrew Underwater ROV http://hardware.slashdot.org/article.pl?sid=05/07/30/1928240 and I think it would fit into a project for my students in computer science. Yes I know its not all about computers, but in New Zealand we fit into the technology curriculum, it would require them to documentate everything they do in a journal and would require some testing and deveopment. Thinking about places to try it out. We have a local public pool close by so we can do trials and development down there as well. Look out 2009.
