Homebuilt ROVs Forum

If you look, Blue Robotics went to a 3-bladed prop on the new T200 thrusters, and most professional ROV's also have 3 bladed props. I believe it's the most efficient in water. They are also usually different from boat props, boat props being designed to work best going forward, while ROV thrusters ...

Here is the prop pieces adapted and created for my walker QRX350 motor. The motor and the cables in the rendering aren't exact, I added them just to see it "built" in the computer. RC-GqFoosDM Propeller_Submarine_2020-Jul-10_01-00-14PM-000_CustomizedView14682417237.png Propeller_Submarine_...

Here is the adapter for the prop I had to modify since I will use different motors than the creator. I am using Walkera QRX350 old motors.

Here are some renders (if you need the STL write me since its to big of a size to upload).

Beautiful shape, only I think that the watertightness leaves something to desire. I think that you can achieve a better succes with swaping the whole dome if required. Because a flat surface is "easy" to make waterproof. All the 3D printed parts aren't required to be waterproof. They are ...

From what i hear, BR is quality materials. They've done their research. Hope it works out for you! They seem really high quality pieces. Its a shame that living in europe I had to pay 30€ just for shipping and now I will also pay the customs duty and IVA which I just recieved and It's really high :...

BlueRobotics team was amazing! Super fast shipping!

They also included silicon grease the little blue stick and a sticker!

This is the 3'' version.

Anyways If the problem is the power why not using a transistor to amplify the signal coming out from the RS485 module?

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 f...

Hope I am not to late...

Your design is really simple. I would suggest you to change software.
Fusion360 is really simple to use and free for hobbyist if I am not mistaken. You can also make simulations of the structure using this tool.

Good luck

Hey I would suggest you to watch this video: https://www.youtube.com/watch?v=Zn4NRQgl2tw
