How I designed the frame for my Underwater...

In my last post “Underwater Alioli ROV” I shared all the information I got from Internet to build my own Underwater ROV. In this post I will explain how I managed to build the frame.

The main thing the ROV needs to become a real thing, is a frame, something where to rest on. After checking several designs from different websites I got ideas all together and made my own version of it. Even if I had a clear idea about how I wanted the frame to look like I had to change the design because of the lack of pipe’s joins. My first version looked like this:

But then I realized that I made some mistakes on the design because it was difficult for me to find some joins. The reason was that I had only the choice of joins of few kinds: 135 degrees (kind of very open “L”), 90 degrees as an “L”, the shape of “T” and nothing else, so I wasn’t able to make the corners as an X-Y-Z Axis. This was the reason I decided to add some changes to make it compatible with what I could find in normal shops. Here is the version 2 of Alioli Underwater Rov:

I started building the frame and here you have a step-by-step how to build it:

Next steps

After building the frame the next steps are to drill holes on the pipes so water can go through and put the structure together using screws. Then paint it with preparatory coat and paint it on yellow so it will start looking like a real submarine.
