Diy remote control submarine with camera12/15/2023 The ideal is a small amount of positive buoyancy, so if things go wrong the ROV will eventually float to the surface. The Dry Tube contains the electronics and provides most of the positive buoyancy. Fourth pic shows pulling apart the dry tube. Third pic is more of the same plus the additional bump for potting depth meter and its wires. Second pic attempts to show how thruster wires are led into potted bullet connectors. The intent is more to provide a resource that someone might draw from if they intend to build their own submersible ROV.įirst pic is the buoyancy test. This Instructable is not intended as a set of directions for doing it yourself. Turns out this was also a bit of a challenge. This way the driver doesn't have to move the left stick at all except for diving/surfacing or turning to a new heading. And "vectored thrusters" sounds cool.įor ease of driving it, I wanted depth hold and heading hold. Separate thrusters are used for diving and surfacing. Driving Mecanum Wheels Omnidirectional Robots). I had built a mecanum wheel rover already and I thought the math there would apply. This means the side thrusters are mounted at 45 degree angles and combine their forces to move the ROV in any direction. I looked online and saw some pricey ROVs and saw a few with "vectored thrusters". This is the same setup used on quad-copters, etc. The left stick is Up/Down and turn Clockwise/CCW. On the 6 channel transmitter I used, the right stick is used for forward/back and left/right. I didn't like the idea of having a wire dangling from the driver's controls, and I have a variety of radio control transmitters already, so that's the direction I went, with the transmitter and control box separate. My goal was to have it not cost a fortune, have it easy to drive, and to have a camera to show what it sees underwater. But it was a fun project and I think it was quite successful. How hard could it be? It turns out that there were several challenges to making a submersible ROV.
