Homebuilt ROVs Forum

I recently embarked on a journey for my first ROV. I decided I'd jump right into the thick of things and start off with an arduino controlled ROV. I decided since I have some pretty good knowledge with computers I'd try to make a GUI with some help and use that to control the arduino which controls the motors, etc.

Specs:

Frame material: PVC Pipe, WET frame, very slightly positive buoyancy.
Controls: Home Made GUI, camera mounted on board.
Lighting: 12vDC LED Light
"The Brain": Arduino Mega
Motors: 6 1100GPH bilge pumps, unmodified.
Power: two 5000mAh batteries on board, 3 cell LiPos
Sensors: I have a digital compass from sparkfun, and an acellerometer, a water sensor in the main housing and camera housings, and battery level monitors.
to come: claw, better lights, better camera.

I'll attatch a picture of the GUI now, It's going to be changed a lot from now until tomorrow when I get it prepared for first launch.More pictures will come tomorrow

ALSO: I will attatch the wiring scheme.

Nice setup. If you change the resistor for water detector to 5-10 M ohm the water detector will also work on fresh water. I have the same type of water detector.

I love it man
I am also redoing my setup to use a mega but haven't gotten as far as you have.
Nice work.

that is a good start. don't forget those diodes between the motor leads otherwise you'll be replacing those fets pretty regularly. I'm not sure you need two fets in parallel, though. your bilge pumps only draw about 3.5 amps max so you'll be well below the power rating of those fets.

good luck!
