I am reposting this in this section of the forum because i think it is more appropriate here and might get more answers.
Hello! I am a newb at building ROVs, but I am really interested at building my own. I plan to assemble the frame out of PVC pipe. The thrusters will be 4 modified bilge pumps, 2 placed horizontally to go forward and back, and for turning, and 2 placed vertically for going up and down. That part is pretty straight forward. Now the part I'm not so sure about...Electronics.
I plan on using an Arduino Uno to control everything, but I'm not sure the best method of controlling the thrusters and motors to make them go in either direction. I also plan on having a webcam that can be tilted by servos. I have heard the USB will not be be good for the tether, so i plan on getting 2 USB-Ethernet adapters so i can change it use an Ethernet tether.
To waterproof it i plan on making a PVC hull that is sealed on one end and has a closet flange and polycarbonate on the other. The camera will look out of this and i can easily pull out the flange to do any modifications to the electronics/inside.
Would this work? Have any suggestions to make this better? Please, help a newb in need.
