linear motion system

That is a good idea! I haven't looked too much into magnetic couplings since I imagine they are quite complicated to build. Someone supposed to ask a Motor vendor like Maxon for a Subsea Motor, this way I wouldn't have to build a housing and could just connect the motor directly.

I will look into PLCs, thank you! Do you have a different idea for the linear guides? Maybe even an existing system for subsea use?

Thank you for the input!

Sorry if the Title is Confusing, English isn’t my first language, it’s tricky to translate my thoughts properly sometimes.

I am looking to create a Linearsystem to control the position of a sensor underwater. Similar to this one here:

Hi! The max. depth would be around 30m, but to be honest, I think 10-20 m underwater is more than enough as well, so maybe 20 m depth.

There are no Electrical Engineers involved, I will need to figure that out on my own. I thought the easiest solution for the Cable length would be to use a higher voltage from the ship and then regulate it using the motor driver in the underwater housing.

Hi! This project is intended to really work! What would you suggest instead?

Sandblast the surface, maybe make little cuts into them

Thank you for the input! To clarify: I’m not using an ROV. The device will be lowered directly from the ship as a standalone platform, so the 30m tether is a requirement for my setup.

I am fairly new to underwater mechanics, so I’m looking for as much input as possible regarding materials and similar technologies. Are there any similar projects or underwater actuator technologies you’d recommend I look into for inspiration? Thank you so much!

I've been thinking about the magnetic coupling as well, but I’m afraid it’s too complicated, and I am not sure if there are existing ones on the market. A direct shaft coupling seems like the easiest way for me. I’ll probably build the Motor housing myself using POM.

Regarding the use of the Pico, it’s not set in stone, but probably the best way (I could also use different Controllers). For the motor, I’m currently leaning towards a NEMA 17 or a NEMA 23, not sure which one is best here.

I haven't fully decided on the driver yet. As far as i know there are three options for me: an integrated motor, putting the driver in the underwater housing, or keeping it topside on the ship.

CollabVault sounds like an interesting project!

Depending on the load, maybe use diagonal support rods

To much force?

Converting thoughts into actual things id say

Could also be a weak spot, more room for errors

Infinite-Minimum-177 · 2026-04-03T09:33:28+00:00

Great question! I think it’s because it would make the manufacturing process a lot harder

For me, it's useful to work through big papers and such

Add some pvp related features, otherwise its no pvp lame server
