Modular sensor-integrated- AI anomaly detection Robotic ROV for submerged Environmental Analysis

This project presents a modular Biosensor-integrated Remotely Operated Vehicle (ROV) designed for submerged environmental analysis with a main objective on coral-reef health assessment using the incentives of AI networks. The system is engineered to support environmental monitoring tasks particularly in coral-reef ecosystems which are estimated to sustain up to 94% of marine life according to recent ecological studies. The platform incorporates high-accuracy CTD sensors and a suite of biosensors capable of detecting biological and chemical indicators of reef stress. These measurements are supported by hydrodynamic framing, multi-vector thruster placement, and a stabilized sensor suite that enhances data fidelity under varying flow conditions. A computational analysis module integrates CTD and biosensor data with computer-vision based species identification and anomaly detection allowing real-time classification of irregular patterns such as bleaching signatures and water-quality deviations. A two-axis manipulator arm maneuvered by a differential gear mechanism and equipped with a precision claw that allows controlled physical sampling and interaction with delicate substrates, for simplicity on a custom water sampling system. Comparative analysis against advanced U.S. ROV systems shows performance gaps in tether bandwidth, thrust-to-weight ratio, and autonomous correction algorithms, while also prototypeing strengths in sensor integration, modularity, and low-cost mechanical efficiency. Making this ROV a significantly better operation than US ROV’s .This work demonstrates that a compact, accessible, and computationally enhanced ROV can serve as a viable tool for coral-reef research and environmental monitoring particularly for institutions with limited resources.

Hi, since you're aiming for this to be a tier 1, could you please code some firmware showing how the bot will work? Additionally, is it possible to add some complexity?

Hi, your README doesn't show how the parts are supposed to fit together, and there's no sort of wiring diagram - if this is a CAD only project with a raspi, this will probably be approved as a tier 3 at best. You are still requesting a precision screwdriver set and MicroSD-card reader that cannot be approved, you have no BOM.csv file showing where your grant will go, and your files are still unorganized (yes, it is possible to make folders in GitHub, even on old Ubuntu systems)

Your README is still AI-generated. (this is your final warning) Additionally, we cannot fund an ethernet cable, and is a microsd-card reader really necessary for your project? Finally, please immensely expand upon your readme showing your design process and descriptions of what you did to get here, organize your files into CAD and Firmware folders, and explain why your bom adds up to $550 when it only should add up to ~$200?

hi your readme isnt really readable. it looks like an ai generated readme as well so please rewrite yourself and make sure there isnt like a huge block of text. also needs a bom.csv because I have no idea why you need the funding and like schematics for electrical components

same issue as before, theres like no images in the readme (even just renders of the cad and any eletrical components and assembly and stuff) and also your repo needs to be organized in folders nicely

Your readme is incomplete (no images renders etc), and not enough files for validation(all project files should be in repo including cad pcb anything else)

3D Printed

Glad to say everything printed just fine! heres a full assembly excluding the motors and battery stuff of course. This is the CAD let me know in the comments if you want to see the parts printed in real life.

Internal Hardware

I made my internal component holder for better, dc converter, battery, wifi router, etc. Its around 6 inches in diameter and will be contained a a water tight acrylic dome.

Please check other cheaper retail sites such as Aliexpress or Temu, as Amazon is usually the more expensive on the bunch.

Printing Time

I started printing my parts took awhile to get everything set up on the build plat efficiently especially while using a ender 3. But anyway my color scheme is green black white as there neutral colors in marine life eyes.

Differential Claw design

For under water purposes I found a differential system would be best as from 2 servos I would get so much more degrees of freedom and I wont need high torque from another arm instead of a differential.

yugumasudhan added to the journal 12/23/2025 at 9:06 PM ago

Turret Assembly

I just saw how everything fit together from the cad of everything, and found out where I could use epoxy or just normal screws to avoid rusting. Fixed some errors I saw.

yugumasudhan added to the journal 12/23/2025 at 9:03 PM ago

ARM

I decided on a 2 axis freedom arm for simplicity especially if I am underwater. its hollow on the inside as it means less pressure on the arm itself and prevents water leakage from pressure difference.

yugumasudhan added to the journal 12/23/2025 at 9:00 PM ago

ARM Design

I started designing the high torque turret for my underwater sample collection system. it will be using a edited micro 12g servo water proofed using oil by me.

yugumasudhan added to the journal 12/23/2025 at 8:58 PM ago

Created base assembly

Today, I tried my best to find how all the parts would fit together and find potential leaks or issues that might show up in the build process. And tomorrow we will start printing!

Top Deck

I designed the overall brain of the ROV using a raspberry pi 4. I will be using a slot for a 2200mAh battery as well giving a great dive time for the ROV.

Designed Buoyancy weights

I researched what US Navy ROV's use as weights to adjust there depth

in water. I decided on lead shot balls around 2 pounds evenly distributed between the front and back held is a container with 1mm holes.

yugumasudhan added to the journal 12/23/2025 at 8:51 PM ago

Design motor clamps

I essentially ordered my motors and measured out each radius to adjust in the cad for a proper fit on the actual ROV. I also spent time figuring out how to use bilge pumps as a DC motor as it can withstand hundred of meters of pressure.

yugumasudhan added to the journal 12/23/2025 at 8:48 PM ago

Side-Plates

Design Side plates for ROV and bilge motors. Polish design and fix tolerances. There's a picture for you guys. I also rendered these in blender.I also started the turret arm.

yugumasudhan added to the journal 12/16/2025 at 11:42 PM ago

GitHub/ BOM

I made my github repository, and formed a pre-design material checklist. This was to ensure I am able to account for everything in the CAD and nothing is left out! Also can someone tell me how to ask for a grant, in the comments.

yugumasudhan added to the journal 12/16/2025 at 9:37 PM ago

Propulsion wing design

I used Onshape CAD software to design my propulsion thrusters and tested it using simulation software to find the best prototype. I also started finding motors that withstand the water pressure for up too 300meters.
