Submarine ROV Robot built from Scratch

This is a video of the ROV that my son and I and a few of the members of his ROV class built. The video explains why it was built the way it was. The ROV was never completed that year but was completed by the 2013 2014 years ROV class. The ROV class made a few changes completed the control box painted it and they placed third place at the NASA Neutral Buoyancy Lab competition. The folks there said it was the first time a Home School Group had placed. Congratulations and Good Work Guys! Please comment and Like if this video helped you or you liked it. The only thing for this simple robot I think it could use would be a higher gauge wire.
