r/rov

Hi r/rov ! So i saw Austin and Psychomaneshark's posts asking for cephalopod sightings and i thought it would be a good idea to give a shout-out.

We're putting together a paper reviewing currently known deep-sea anglerfish sightings. So far we have a few coming from commercial sources thanks to the SERPENT project.

If you have *any* such sightings plz feel welcomed to forward/send them to me in dm! I'll review them first to make sure they are indeed anglers before sending them to the first author and senior author. Thanks!

I wanted to share a project I'm starting: I’m working on designing and building a diy rov from scratch.
Right now,i’m in the early reacher and development phase,focusing on the mechanical frame and the thruster system.For the tech and control side,i’m planning to build it using the nvidia ecosystem like jetson.
If any of you are into robotics,3D printing,embedded system or nvidia development.
i’d love to connect,swap ideas,or share useful resources!
See you in te chat!

Greetings all!

My name is Austin and I am one of the founders of an organisation known as the Cephalopod Research Network (mostly Discord/Instagram based) until we get more footing. We are currently setting up a "species library" where we will be tracking footage and or photographs of species from all cephalopods (squids, octopus, nautilus, cuttlefish, bobtail/bottletail squids, etc), which we hope can be useful for a new website called CephRef (still under development).

If anyone has any cephalopod footage to share, please let me know. And as always all credit will be given to the person, and if you don't want your videography or images put onto Cephref in the future, they wont without your strict permission, but the library itself is being only built for Cephalopod researchers

If you have any questions about the species library itself, or Ceph ref, or if you are unsure what genus/species you are looking at, please feel free to reach out, we have many experts dedicated to all groups of cephalopods

Happy Squidding!

Austin

Hi, my name is Erik, im from Spain. I’m 15 years old and I’ve been into robotics since probably 5 years old.
I have recently decided to build my own rov, which will be capable of diving to 300m depth.
I’ve never done any underwater robotics stuff, so it’s a difficult project for me.
I decided to create a YouTube channel to share my journey, and it is the first ROV themed YouTube channel in Spanish in the world.
I’m a beginner so please excuse the dumb mistakes I might make.
Any support to this channel will be incredibly appreciated.
I just posted my first video today and plan to post one each two weeks approximately.
I’ll leave the link so you can check it out and drop a follow if you like the video.
If I get some subs YouTube will enable automatic translation so you will be able to watch the videos in English.
As I said, any support will be greatly appreciated!

Hi all,

Im working with a few ports and other water companies where i do ROV inspections. we recently purchased a big ROV with sonar and other gadgets, but its a heavy 32kg ROV

The issue is that its heavy and lifting it in/out of the water is an issue. We also work at varying/remote places all the time, so we cant montage a strong crane somewhere. We do have a transport van.

We found a solution of a 3M davit, but the arm is too short for most of the tasks. Thats why i decided to come here and ask others around the world of solutions to get an ROV easy into the water when its heavy and big

Im designing and building an ROV for myself, this is my first venture into the ROV world. Im trying to build a vessel capable of depths of 500 meters. i live close to Lake Chelan in Washington state, which has a max depth of 453 meters, so thats my goal.

Budget wise im trying to stay around $1000 for the vessel itself, Fortunately for me, i have access to machining and tooling to build much of the mechanical components myself. Really the only things i wont be able to build myself are the electronics, but ive got most of that sourced already. The only thing that im having a difficult time with is finding a suitable tether for not an egregious price.

My question is: Are there any suitable off-the-shelf options for making a tether capable of withstanding 500 meters for a reasonable price?

If i can make the tether for under $600, ill be happy. I know traditional copper cored wire has data loss issues at length, so im leaning towards fiber optic as it is.

I am a Class 12 student building a low-cost DIY underwater ROV for a science project.
Current components:

• Arduino UNO R4 Minima
• Freenove ESP32-S3 WROOM with camera
• Three 12V 775 DC motors
• SG90 servo
• pH and turbidity sensors
• 12V battery

Constraints:

• Budget approximately ₹10,000–12,000
• No 3D printer, CNC machine, or laser cutter
• Construction must use acrylic tube, PVC, hardware-store materials, and basic tools

My current plan is to use a transparent acrylic tube as the pressure hull and mount three thrusters for propulsion and steering.
What are the most important design considerations for:

1. Waterproof motor mounting
2. Shaft sealing and cable entry points
3. Hull construction using acrylic and PVC
4. Maintaining stability and buoyancy
5. Common mistakes beginners make when building an ROV

I would appreciate advice from anyone with experience building small underwater robots.

I am looking to measure the RPM of a propeller underwater non-intrusively. I've looked at waterproofing a laser tacho, but I'm worried about scattering. I've seen that a hydrophone could theoretically work, but I want a relatively simple solution. I'd like to initially stray away from indirectly measuring the RPM with the eRPM. Any thoughts?

Hey everyone! I am an FTC competitor here from the Santa Clara area. I'm looking to start a community-based underwater robotics team and wanted to see if any high schoolers nearby would be interested. The plan is to compete in the MATE ROV Competition, building underwater ROVs for environmental missions. It'd be fully independent, open to any high schooler in the area, regardless of school.

Looking for people with any background in:

- Robotics (FTC/FLL/FRC experience a plus)

- Electronics/Arduino/Raspberry Pi

- Programming

- Environmental science

Drop a comment if you're a high schooler in the Bay Area and interested. Just gauging interest for now!
