Neptune a Raspberry ROV

[ZacharyMoran]

Good Afternoon Everyone,

Just thought i'd post alittle about my project maybe get some feedback.

I'm designing a mostly printed ROV, the only components not printed are the hull.
in addition to being printed my ROV is controlled by 2 raspberry pi's and a nodemcu.







Here is a few images.
The basic design is the 3dprinted frame attaches to a PVC hull.

The frame has three bilge pumps, 1 for depth and two for horizantal movement.

The Thrusters get wired into the hull using the above black wire plug.

Once wired in it's attached to a few hbridges and internal pi controls using PWM signals

The water pi uses a nodejs server to host all webpages and etc also motion software to send a usb camera signal back above ground.

The nodejs app uses websockets and etc to control the thrusters.

I have a ground pi as well connecting to a NODEMCU the NODEMCU host's a wifi accesspoint my mobile phone and the ground pi connects to.

The ground pi acts as an ethernet bridge.

The NODEMCU is connected to a lcd display which displays status and etc on the ground station.

Let me know what you think.
Thanks for taking time to look at this writeup.

I'm sure the formatting needs work but hopefully i got my point across!

I am also thinking in using two rasbperry to make an ethernet connection and pass data from the surface to the ROV. I am thinking to put a hub in the rov so to connect various ethernet cameras and obviously the rasbperry; do you think its feasible?

Can you go a bit more in detait on the cap of the first picture?

What is the depth you think you will be able to get before the dry hull implodes?

Hope it will go well!


Could you give me, if you have them, some good resources to learn how to use nodejs. I know how to use sockets only in C using file descriptors.

Hi There!

I can actually upload all code to github and share it with you!

The endcap thing is totally a guess and i have no idea if it will hold water

These are the caps
Then i used standard marine epoxy.

If you want to learn nodejs i'd suggest youtube but also W3Schools has a great tutorial!
take a look here

Hope this helps will post more as i go!

My design calls for the use of a PVC hull too.

I plan to bring the tether wires through along the side with a plug inside to remove the entire guts. I plan to use a plumbing test key to seal it up for the dive, but allow access at the surface (replace wing nut with a locknut)...

Buenas noches.
Lamento tener que decirte que no soy programador, y que no tengo ni idea de cómo hacer funcionar la Raspberry, tengo a medias un proyecto con Arduino, y bastantes problemas con la programación, pero aun así, seguiré tu proyecto por los pasos de construcción de la caja seca, y la motorización del ROV.
Un saludo.


Good night.
I'm sorry to have to tell you that I'm not a programmer, and that I have no idea how to run the Raspberry, I have half a project with Arduino, and quite a few problems with programming, but I'll still follow your project through the construction steps of the dry box, and the motorization of the ROV.
Greetings.
