ROV for college project
Posted: Jan 22nd, 2016, 10:54 am
Hello!
I am building an ROV for my graded unit at college.
The specs/features I would like on the ROV are;
33m tether
Raspberry Pi Noir infra red control camera to surface
Dazzne P3 HD action cam
4 Rule bilge pumps with props
Laptop displaying video feed from Pi Noir
Homemade lithium ion battery pack
Adjustable buoyancy using bicycle inner tubes
Depth indicator
Otterbox 3250 for electrical items

I started this project years ago, but didn,t understand much about electricity so it went in the loft. Now i,m studying a degree in electrical engineering and I would like to finish this as my project. The ROV will be used to explore flooded mine workings, this will be used for my hobby (mine exploring).
I would like the ROV to have a 33m tether, I will be buying 3 100m rolls of 1.6mm CSA single core wires for the thrusters.
I have lots of questions to ask, mainly regarding the drive system.
I,m going to use 4 thrusters, 2 forwards/back, 1 to point the nose up or down, and one on the nose to turn left or right. Is this a good way to control it?
I am worried about volt drop on the Noir camera over the 33m, so I,m wondering if I should have the Pi on the surface and extend the wires to the camera, or have the Pi underwater and send the signal up the wire to the surface?
If I have 4 thrusters, controlled by 4 DPDT switches would that mean I need 8 wires? Can I share a common earth?
The Pi NOir has its own IR lights built in, I was thinking of also fitting a seperate IR light from a security light to provide additional light whilst underground, would this help visibility?
Thats all the questions I have... for now
Any info greatly appreciated!
