The "Albie" 3D Printed ROV

- This is a 3D designed and printed ROV that uses basic equipment and the simplest control system I could come up with. Many current ROVs on the market have complex control systems requiring ethernet connectivity to get all the functions to run. This is much simpler, albeit less capable depending on what you are intending on doing with it. For swimming it around looking at the underwater world, this is sufficient, and fun!
RC Control Link:
The control uses a basic RC transmitter and receiver (FrSky Taranis w/X8R receiver). The reason for this paining is that the X8R has S.BUS capability built-in, meaning that the receiver can pass up to 16 channels directly to the ROV using only a single signal wire and a ground wire. So 2 wires, 16 channels! All without ethernet or other fanciness. What it does need is a S.BUS to PWM converter in the ROV to decode the signals to servo signals for the ESCs to use. That's a $15 part at hobbyking.com. Note: Any S.BUS tx/rx pair would do just fine. You could also probably use a ppm rx also, but I did not test it as S.BUS was already available. My tether is 20m long, no signal loss is detected over this length. Great connection! The reason for the RF buoy is really just so that no tether comes back up to the boat, meaning that the 20m length will give the ROV close to that in depth, with no limit (within say 1km of the boat) in the horizontal direction. Cheaper AND more capable.
Motor Control:
Three brushless motors are used and as they can be run underwater without any modification, they are very simple to operate. The props are the ones available on thingiverse.com at the link below. I also used the same motor. Cheap. :)

(3) brushless ESCs are used (Spider 30A Opto) and they have had their firmware changed to be able to have forward and reverse operation. See Google for how to do that. I forget how I accomplished this, but remember that it wasn't hard. :)
Video Link:
In the RF buoy, in addition to the X8R RC receiver there is a standard TS351 Boscam video transmitter. Since we already have 12v and ground coming up from the ROV in the tether, and a third line taking the S.BUS communication, we have one left in the tether. This is the line that the video signal uses. One single wire takes the video from the Runcam FPV camera mounted in the ROV to the surface, and then it's broadcasted to the boat using the TS351.
Put your FPV goggles on and go explore!

you made excellent work.Thank you for sharing the archives.
Thank you very much that’s nice to hear! :)
Thanks a lot...excellent effort..keep up the good work...looking forward to more stuff from you
Great design and thanks for making it sound simple:-)
You just got me wanting to do one, great!!!
Simply effective and great!
Great! great! great! project man! thumps up!
Hey, yes it’s definitely mixed are used essentially the right stick does Left right and pitch. Throttle on the left stick for forward reverse.
Thanks! Today’s test was for mobility. Camera signal looks good but I need to take it to the lake to get anything worth seeing. :) The bottom of my pool is not that interesting! Haha.
Very nice.
я долго искал это видео )) но я настойчивы. спасибо тебе, добрый человек.
This is awesome. I've been considering building a ROV and this is exactly what I was thinking of doing, since my experience is with quadcopters, brushless outrunners and transmitters. I am so tempted to buy this off of you (I'm in KW).
dege13 Hey thanks for the nice comment! It is pretty cool what’s possible these days with the parts we have from RC hobbies that can be combined together into some pretty spectacular new stuff. I did however sell this are Ovi to a nice fellow from the GTA. Apparently he has it running already and is loving it! I posted the design as well as all the 3-D printing parts on the website listed in the description if you were interested in building one.
@@soaringtuna I have already saved the parts on Thingiverse. Hahaha. I will need to start building one soon. I mostly don't trust myself to make it neutral buoyancy and water tight.
@@dege13 Well, just go for it! Any problem you encounter can be overcome. You did however point out the two main challenges in ROV design! :) The watertight part of it is handled by the Blue Robotics 4" housing... its awesome! Follow the potting instructions and it's an awesome design.
very very nice.
너무 좋아요 ~~~
Very clean setup you have. Can you provide link for Buoyancy enclosures?
Thats great
Finally, a homebuilt ROV that doesn't look like it's from the 50s!! Very nice job. I've been wanting to build an ROV using very similar methods and components. What did you use for the tether exactly? Proper ROV tether is so expensive so I've been trying to come up with an alternative.
Levi Temple hey thanks! It worked quite well for a first prototype. Some changes to attitude control were necessary. But the tether is BlueRobotics tether. They sell off cuts once in a while in 20m lengths and so I used that. Given that the control and video goes through a buoy, it’s unlimited distance, but 20m depth limit. Plenty. All the details are on the thingiverse.com page including all the printable parts.
Hello Marc, Not being an RC guy, how to you connect the X8R to the tether? Everything I have read is you use the DSC port, which then disables the radio. I like the buoy idea. Thanks
First of all, really nicely done ! But can you make it RC? Without any attachments? If so, is it possible that it travelled 1-2 KM-s with RC signal?
Hey! Yes you can do it RC if you use 72mhz, or 50mhz. The 2.4ghz modern systems don’t work so well under water. Ever the long wavelength ones are only good to 10ft or so in freshwater, but not at any distance. The buoy control solution was the best I could come up with for both the video and the rc control.
Some fpv footage would be great
hi, first of all, congratulations for the project ... I'm trying to replicate the rov by making some personal changes, but this is the only thing that is not clear to me is how you manage the engine control part ... use a pixhawk aeduino controller etc etc or you have the esc connected directly to the rc .... thanks
how do you control it ? left joystick left motor and right joystick right motor ! Or are you using mixin
well I found what I'm making next
When are you going to make an fpv footage video? I would love to see that!
Mantisman Gaming hopefully in the spring! Everything is frozen here in Canada .... ;)
Nice, any way of getting a copy of the Control Box? Wiring Schematics? Small control board components? I Know we don't have to spend $4000 on an ROV.
Hello. Can i get the measurements of the design? Im actually also developing an rov just like this.
hello. is there no case of a complete step-by-step manual for building this project?
What kind of motors did you use? Brand, model, etc? How have they done over time, any rusting issues?
PROPDRIVE 28-30 750KV - 0:42
Do you have some fpv footage already ?
Which batteries are you utilizing? In the video it seems like zippy battery packs however cant tell if they are 4s or 6s. Can you provide some insight to your battery solution?
Actually, I'm using 3s 5000 lipos... it's surprising how little power you need to make a lot of water move. :)
how much cost those motors and cable,what company you use ??,that look good and seems work well👍👍🤘👌👌👌👏
This is using the waterproof components (including tether) from bluerobotics.com... they have great stuff!
Have you checked the maximum depth? will he be able to descend 20 m? Is there a loss of video signal with a cable of 20 meters?
Hey yes it’s entirely fine at 20m, the canister is good to 300ft. No video degradation through tether.
What kind of cebal did you use?
I have it built and when I try and go upward when it is touching the bottom of the lake it wants to lower the front, making it stay at the bottom. Any thoughts? It works fine when it isn't on the bottom.
Mantisman Gaming hey that’s great that it’s up and running! I found that the forward and backwards buoyancy balance is critical. Also, I have been toying with the idea of increasing the prop size on the up/down motor to make it more responsive.
I ended up going with a larger and lower pitch prop on the top motor to make that part work better.
Where can I type to you? I have some plans and got some questions in my mind.
Already have some more results of ALbie? I'm thinking about printing it and building it. have some more info ?
Marnix Verschraegen hopefully soon! Just started holidays and the lake is angry! Haha 40km/hr winds here for a few days. Have to wait until it calms down.
@@soaringtuna Hey, I am looking forward to your next update.
How much does the entire rov weigh?
It's about 10lbs I'd say. With the ballast weight which is close to 4lbs.
@@edhstechnology thanks! Im just about done printing one :)
Can sell two units for my twin boys.
