Hello,
I am looking at building a one off ROV, Have been doing ALOT of research into the controls and programming aspect of things before I get much further. my goals for the ROV are as follows, 100 Ft depth, live video( with record option) , 2 forward/ back thrusters, with electronic ESC control, one maybe two elevation / depth thrusters, looking to implement joystick control, now I am very versed in arduino and raspberry, but dont like the idea of a wifi phone/tablet to connect to it, I want it to be its on control box , Ie monitor, controller, power all in the surface unit, and the unit to run as long as surface has power supply, I am looking at running everything VIA I2c between raspberry, arduino, nano setup ( still working this out) but want all control and live feed through cat5 , then send power down via a heavier wire to power the ROV ...... what advise can you provide, and what flaws do you see, I really like your ROV , main reason I dont have one is, I want more depth ..... like 100 FT for local lakes and scuba diving spots
Thank you
Couple of things jump out at me. First, the fact that after a week nobody here has been friendly enough to assist you. Second, your control box idea is kinda whacky. Here's why. You're only going down 100 ft. You can create an onboard battery pack out of something like this 18650batterystore .com/21700-p/samsung-40t.htm that would give a 6 thruster, heavy ROV at least 8 hours of autonomy. That's plenty. Besides, a heavy tether is a huge no no. Also, the ones powered via tether use high voltage/low amp and step down transformers onboard in order to use lighter wires but its still better battery pack way. Interface raspberry pi with arduino. For what? Look into Ardusub if you want a more capable, more widely known and supported hardware/software control system with live video feed. Cat6 tether with heavy fishing line is the way to go. Remember the ESC must have reverse. Best.
