“One day while I was on YouTube I saw a man is trying to recover something that missed in a lake using an underwater robot. I was so excited to know what is the magical robot and how it works.
After searching and reading about that robot, I found it’s a robot called underwater ROV(Remotely operated vehicle). Just not only taking an idea about ROV, I want to have my own one. When I seared for an ROV on eBay the result always came with the cost is higher than 1000$. But I am also cheap. Only one way left to come up with my dream. So I went with DIY. I found some people did the same procedure to build an ROV well. Why I can’t???? Finally, I came up with my dream!!!
This Instructable post will show you how to make your own Underwater ROV. An ROV is a robot-like submarine, but the way how submarine is functioning is quite different from an ROV. When writing this post I already finished building my ROV so, in some steps, I can’t show you how I build it with real images, but you can take a great idea than real with the scratch. Fusion 360 always with me, no need to be worry:). The below links are for the ROV builders who had done It well before me, go through their sites and videos before building your own.
