Submarine ROV Robot built from Scratch

- This is a video of the ROV that my son and I and a few of the members of his ROV class built. The video explains why it was built the way it was. The ROV was never completed that year but was completed by the 2013 2014 years ROV class. The ROV class made a few changes completed the control box painted it and they placed third place at the NASA Neutral Buoyancy Lab competition. The folks there said it was the first time a Home School Group had placed. Congratulations and Good Work Guys!
Please comment and Like if this video helped you or you liked it. The only thing for this simple robot I think it could use would be a higher gauge wire.

Excellent presentation, thank you for sharing your knowledge and experiences.
+Bayou Pirate You're welcome Bayou. If you have any questions fell free to ask anytime. Never got to sail here though, the next years class did though.Best Wishes N Blessings Keith.Ps Bayou, me Southern Louisiana.
How did you attach the propellers to the motor?
Hi Augusto, we used a bushing that slid over the motor shaft and used a set screw on the side to tighten it down. Then we drilled and tapped a hole in the end of the busing to mount the propeller and then screwed it on. Feel free to ask more questions if needed. Thanks for watching. Best Wishes n Blessings.

What kind of wire did you use for the tether cable?
LOL love the name! Well that was over 5 years ago. And I didn't get to choose it, I just helped design it with my son and a few of the guys in his class. They already had the cable. I suppose the gauge of the cable would depend on how much amperage you want to push, how far it has to go (Weight of it) and how much thrust your motors can deliver. There's also a matter of buoyancy. If the cable is to heavy it can pull the ROV down so you have to make the cable buoyancy neutral with floats. The the weight of the cable vs the amount of thrust the motors can give. I think they were using 16-18 gauge wire. To get around the weight of the cable you can have most of it float by using floats to keep it on top of the water. The figure out how far down you want to go and make that portion of the cable neutral so the ROV can easily drag it around. Oh one last thing the longer they are the cables act like big resistors and the voltage and amperage drops the longer it is to. So you'll have to use a wire gauge to amperage drop calculator to see if the length is going to affect your end point voltage and amperage. The best cable is a short heavy gauge wire, but the bigger the gauge the heavier and harder the cable is to drag around. By the way wire diameter goes down as the wire gauge number goes up. Most homes use 14 gauge solid copper, you don't want that because solid copper breaks after it bends a few times, you'll want stranded wire because it's flexible and doesn't break easily.
Balance: When designing an ROV to move or carry things remember that the ROV has a balance point in the middle and what ever you pick up must not upset that balance, hence that's why our hook was in the middle of the ROV right under the balance point, both side to side and front to back. Hope that helps you with the information you need. I will be away from YT for a week so if you have any more questions i'll answer them when I can log in again. Best Wishes& Blessings. Keith Noneya
what kind of motors are you using ?
Johnson Bomba Model: 2855. 500 GPH (Gallons Per Minute) Motor Cartucho. As saias são feitos de tubo de PVC no meu torno. Provavelmente poderá torná-los aquecendo-os com um maçarico de butano e esticando-as sobre um pedaço de madeira o mesmo diâmetro que o motor.
Boa sorte com seu projeto de João Vitor.
Muitas felicidades e bênçãos. Keith
Johnson Pump Model: 2855. 500 GPH (Gallons Per Minute) Motor Cartridge. The Shrouds are custom made out of PVC Pipe on my Lathe. You could probably make them by heating them with a butane torch and stretching them over a piece of wood the same diameter as the motor. Good luck with your project João Vitor.
Best Wishes and Blessings. Keith
What propellers did you use
Sorry I wasn't the one who purchased them, they were purchased a few years before my sons class even inherited the project. I think they are just RC boat propellers. Hope that helps. Thanks for watching and I hope you found some useful information in the video. Best Wishes & Blessings. Keith Noneya
