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

The main thing the ROV needs to become real is a frame, something to rest on. After checking several designs from different websites, I got ideas and made my own version. 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 joins. My first version looked like this:

But then I realized that I made some mistakes in the design because it was difficult for me to find some joins. The reason was that I had only the choice of joins of a few kinds: 135 degrees (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 why I decided to add some changes to make it compatible with what I could find in usual shops. So here is version 2 of Alioli Underwater Rov:

Here you have the Blender 3D project just for downloading:

• Alioli Underwater ROV Frame v2 Blender 3D design.

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

Next steps

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