Underwater ROV - Home Built

[@B.Cote39]

The simplicity is brilliant, thank you for sharing

[@mihavatovec5770]

What interest me is how to protect the motors so the water dont come in

[@jameswebb8162]

Awesome video. New subscriber, can’t wait to start building my own!!

[@Entrak]

Very educational, thank you. Currently working on my own ROV system, using Arduino and H-bridge relays to control the motors with PWM and had some issues in regards of design that your video resolved for me.

[@Gajakoshshraddha2607]

Could you attach the components used please?

[@paulcorrigan7999]

That was the most helpful ROV video I have ever watched.

[@kshitijbithel3238]

Can you advise a simulation platform to simulate the ROV basic control

[@braintechlifestyle8244]

Please Can you do a simulation of this rov on MATLAB ?

[@Muhammad-kp3cu]

great video , i need a little help how you select a motor and propeller ,to move a certain weight if the velocity is constant for say 4 knots in salt and fresh water, as the density of fresh water and salt water is different, if you know any formula or any material regarding this problem , please guide me . i will be thnakfull to you

[@agermangineer]

Well done! Always fun to watch these gadgets perform so well! Thanks for sharing!!

[@KyleMatt11]

Great vid. But I can’t find your video about how u use a computer to program control system. Can u Please advise

[@rafeemiracle]

u can use arduino to control it by using relay and the rov will connect by ethernet cable to ethernet Shield on the arduino

[@AlanSaltman]

I was going through some older videos and spotted yours. ROVS have come along way since then nice job

[@michaelrtreat]

Very educational. Thank you

[@naveenprajapati4599]

Sir can you make a video about acoustic communication

[@cihatkursatkalkan8839]

Can you say what type of motors did you use ?

[@discoverymapp]

This is awesome dude! Great work!!

[@bobinsd1]

Are you in CA? If so, where?

[@canalfutebolraiz]

Nice video! Brasil

[@yildiz12321]

Thanks for sharing...

[@rozzinfataulwan2496]

Nice, thanks sir

[@pikahsteadey]

what type of motor (for propeller) did you use? thank you

[@sobrunatfal]

Biasanya kita bisa pakai motor bilge pump bu. terus kita custom shaftnya.

[@naveenprajapati4599]

It's awesome Ur awesome

[@beto798]

Great work

[@enigma3654]

Can we get a link to the relays you use

[@labratscientific1127]

The relays I used were items I scrounged up so I can's suggest any sources - sorry.

[@jugul07]

Where do you buy the motor sir ? Answer me pleas

[@labratscientific1127]

The small ROV just used small 12 VDC motors that can be bought on line or maybe from an electronics store. Motors could also be scavenged from toys... The large ROV used 12 VDC trolling motors - to the tune of $120 each. I carefully cut off the long shafts and cut the wires that were inside the shaft at the speed controller end of the shaft (to make sure I had lots of wire to mess around with). I then used some PVC fittings and 5-minute epoxy to seal up the wires where they run into the motor housing. This sealing part is important...

[@jugul07]

@@labratscientific1127 thank you sir

[@georgehabib4333]

What did you use to extend the shaft of the motors (the ones in the film canisters) and attach the propellers?

[@labratscientific1127]

I didn't have to extend the motor shaft. The motor presses up against the bottom of the film canister and the shaft is long enough to stick though. I then simply press the propeller on the end of the shaft. The trick is to find a propeller to fit the motor shaft. You can probably find propellers at your local hobby shop (I suspect some still do exist), or order them on line...

[@georgehabib4333]

LabRat Scientific Thank you for your response. The shaft does extend beyond the housing for me toobut I’m worried it’s not long enough for the propeller to attach. How much roughly in mm is needed?

[@labratscientific1127]

I would first obtain the propellers and see how much engagement is required. I suspect 10 mm would be OK. However, it might be better to get the propeller farther way from the canister so you get good water flow. You could extend the shaft by getting a small brass or aluminum tube from a hobby shop that has an inside diameter about the same size as the motor shaft. You could apply some 5 minute epoxy in the tube and then slip it over the shaft. The tighter the fit the better... You can also get some piano wire with the same diameter as the motor shaft from the hobby shop to make the extension. Epoxy a section of the piano wire in the other end of the tube. The tube serves as a coupler... The tube and piano wire are generally associated with RC airplane supplies. If you can drill out the hole in the propeller you could just slip it over the tube rather than using the piano wire extension.
