Making an PVC ROV Sub

This is an update to the underwater ROV submarine built a while back. It has an improved design, and is more versatile. Maker Jason writes “…the build process, and parts, I used to build an Underwater ROV with camera – This will be version 2 of my ROV adventures, I plan to take things I learned from version 1 and fix them, plus I will be adding features later. The plan is to make this a flexible platform that will allow me to add things like temp/pressure sensors, air lift balloons, torpedos, sonar, grabbing arm. But stage one is going to be working the bugs out the main platform.” [via] Link.
