This is my first ROV Project which is already underway. Here is a list of specs.
- Dimensions: 42"L x 14"W x 10"H (excluding control surfaces and thrusters).
- Hull Design: Oval (similar to an old Russian Typhoon Class Submarine).
- Hull Material: Fiber glass & Carbon fiber.
- Power: Internal from 2 - 18AH agm batteries.
- Thrusters: 4- T100 Thrusters from Blue Robotics w/ESC.
- Control: Logitech Wingman 3D Pro Extreme.
- Lights: 2- 3000 Lumen Cree T6 LED’s.
- Camera: 1 PTZ IP Camera. Bow Mount.
- Sonar: 1- Raymarine Dragonfly 6 GPS & Transducer.
- Electronics: Arduino Mega, 2-L293D Motor Control Shields, 1-5 Port Ethernet Hub/Switch, 3 Servos(TBD).
- Ballast: Fiber glass & Carbon Fiber Air Tank, 4- Ballast tubes w/ rubber bladders and 2-12vdc Soleniods.
- Possible Addition: Digital Compass/Directional Heading.
I have begun the construction by cutting the basic hull mold out of stryofoam. I am in the process of coating the mold with plaster to further smooth and refine the shape. I have built the mold for the air tank and have all the fittings on hand. Next step is to fit the 2 thruster shafts, the rudder shaft, camera view port and light housings before fiber glassing and the carbon fiber finish. The camera view port is 1/2" thick acrylic plexiglass which I have to shape to fit the bow. I have already made a concrete cast of the bow to use for shaping the plexiglass. I did the preliminary design in CAD and have made all my patterns from that. As I am focused on inland fresh water lakes, I don’t intend to go below 100’ so I plan on a hull thickness of ~3/8". The air tank will hold approximately 100 psi and is also going to be ~3/8" thick. I am not sure how many ballast cycles I can get from a single tank, but I will determine that through testing. I will be cutting a ~12" x ~12" hatch in the top of the ROV. I will use 2" x 1/4" thick 6061 aluminum bar stock to make the hatch plate. Most of the items are on order or already in hand other than some of the more pricey items. I welcome any feed back or questions.
