Homebuilt ROVs Forum

Dry fitted the ROV today and it was more buoyant than I calculated. I will be making one of the cross pieces wet. Easy to do when I am using snap on tees. The good news was that it was plenty stable! I poured some lead sticks to glue to the inside of the lower pipes and was surprised how much weight...

For the rov I am building now, my calculations show that I can achieve a slightly positive buoyancy by sealing most of the frame. I am using 3/4 class 200 pvc which is thinner walled than what others are using, it's made to handle internal pressures of 200 psi.. I am planning on diving no deeper the...

I have decided not to use the inner plugs like those in the link I posted. I am using several of these snap on tee's that are meant to be glued to an existing pipe and then drilled out. My concern that I need to test is if I make the frame sealed and close to neutral buoyancy will it end up being ve...

Nice website, your calculations assume that the skids and cross members are all sealed and thus displace water based upon their OD. Looking to build my first rov, I see that many folks seem to allow water into their entire frame which would dramatically reduce the displacement. I am looking to seal ...

I am in the design phase of my rov. I am planning on using 3/4" class 200 pvc and assume it should be fine down to 60-75'... Thoughts? I am considering sealing a portion of my frame for buoyancy thereby avoiding large floats. My preliminary calculations are positive. Has anyone else done this? ...

I tried calling the company today, no answer and no mention of their business name in their voicemail, maybe they will call back?? I want to find out about the brightness, rated depth etc. Concerning This part of the project has been the toughest for me in the planning stage. I really want to be abl...

I am thinking about using a fishing camera system for my ROV, does anyone have much experience with them? My biggest concern is getting a display I can see in the sunlight. These were the models I am considering : http://www.cfish.com/underwater_fishing_camera_order.html The more expensive one has a...

I have been lurking on the internet for a couple of years thinking about building an ROV. This is the winter I am going to do it. We boat in the summer in the San Juan Islands and I want to explore the anchorages and around the State Park docks. I gave been forming a design in my mind and have even ...
