This remotely operated vehicle was created thanks to the brains of Jason Rollette, who’s been at it for about five years. This is the second version of his ROV submarine, which is built mostly from PVC tubing.
This kind of reminds me of the movie Abyss for some reason. The ROV submarine uses four 500gph and two 1,250gph bilge pumps. The bigger ones are used for propulsion while the smaller ones are used to dive and surface.
It’s got lights and naturally a functioning camera, which lets Jason guide it into the depths. Jason actually designed some non-explosive torpedoes as well. Sweet. Incredibly, all of the parts needed to build this sub are available at any home improvement store.
