Have you ever been captivated by the idea of exploring the depths of a lake or ocean with your very own underwater robot?

How hard could it be? It turns out that there were several challenges to making a submersible ROV. But it was a fun project and I think it was quite successful. My goal was to have it not cost a fortune, have it easy to drive, and to have a camera to show what it sees underwater. I didn't like the idea of having a wire dangling from the driver's controls, and I have a variety of radio control transmitters already, so that's the direction I went, with the transmitter and control box separate.

When I first started documenting this project on my website, I intended to explain every step of the process both physical construction and software development in as much detail as possible. I believed that doing so would better help anyone who wanted to attempt this for themselves and clear up any confusion particularly regarding the code. Such detailed documentation has presented challenges however. All of this makes for a very laborious effort in maintaining this website, and as a result I have decided to explain things in more brief and "abstract" manner with links to my assembly code files as references as opposed to posting screen shots of code and giving a detailed explanation in paragraph form. If at some point I feel that a particular part of the software will be more or less "frozen" and unlikely to be significantly changed in the future, I may come back and provide more detailed explanations. At this stage however, there is little chance that anything about the project will remain frozen for long, which is why I have decided to change my approach to documentation. After over four years, this project has reach "end of life" status due to time and resource constraints. All design files source code, schematics and repository are effectively frozen and will not be updated or developed further. I was looking for a project that would provide a significant challenge, but at the same time not be so daunting as to be nearly impossible given my skill set. To be quite frank, it has proven to be a bit more daunting than I originally imagined funny how that works , but in an encouraging way that has caused me to learn quite a bit. The list of topics that I had almost zero prior knowledge of before tackling a submersible vehicle was quite large. Serial protocols, voltage drop across long lengths of wire, brushless DC motors, electronic speed controllers and many more

Underwater exploration and research can be exceedingly dangerous, which is why remotely operated vehicles ROVs are so commonly used. Operators can remotely command these small submersibles to capture images or collect samples at depths which would otherwise be unreachable. Unfortunately, such technology comes at a considerable price. Constructed largely from off-the-shelf components and 3D-printed parts, the Aruna promises to be far more affordable than anything currently on the market. Hopefully cheap enough to allow local governments and even citizens to conduct their own underwater research and observations. More than just the ROV itself, Aruna represents an entire system for developing modular underwater vehicles. Is the center pipe thing pressurized or not? I worry more about the sealing of wire junctions and splices than the motors themselves, tbqh. The brushless RC motors are definitely a consumable. Run them for a few dives and then throw them in the trash.

First post of ! With the advent of the raspberry pi and easy access to code the past few years this project was something that seemed more feasible than before and I decided to dive in head first pun intended. Most of the project is DIY but a few of the important waterproof parts were sourced from blue robotics. Our ROV is going to need a frame, and what better else material to build one out of than extruded aluminum. I am not very savy with CAD programs but I did find a software Maytech that lets you design structures in extruded aluminum. For the frame I chose rail with a double smooth side.

Third pic is more of the same plus the additional bump for potting depth meter and its wires. I did however want to build my own control-device that could operate completely independent of a laptop computer which is the manner used to control most ROVs on the market. All design files source code, schematics and repository are effectively frozen and will not be updated or developed further. Here are the results of my own testings:. The First Successful Test: Testing Beyond the Bathtub: While initial testing took place in my bathtub, the real milestone was achieved during a test in a larger body of water. Such detailed documentation has presented challenges however. Enjoy capturing the wonders of the deep! This DIY project not only offers valuable hands-on experience but also the exciting prospect of exploring underwater environments with a ROV designed to meet your specific needs. If at some point I feel that a particular part of the software will be more or less "frozen" and unlikely to be significantly changed in the future, I may come back and provide more detailed explanations. Installing the Onboard Battery: Prepare Battery Wires: Solder two wires to the positive and negative terminals of the battery, ensuring secure connections. This means the side thrusters are mounted at 45 degree angles and combine their forces to move the ROV in any direction. This meticulous approach will result in a neatly organized and reliable meter tether. The choice of colour is entirely yours, so express your creativity! To ensure you have the right thrusters for your ROV, you conducted thrust tests. Ensure that all connections are properly insulated to prevent water ingress.

DIY traditionally means Do-It-Yourself and refers to the culture of building or creating things that can be bought. At DIY. Within this community, we encourage them to create, share, and interact with each other over shared interests, without the fear of negativity, bullying, or predatory behavior limiting them.

The top tubes are sealed, filled with air, and equipped with end caps. It's a cost-effective way to start your underwater adventures and serves as a stepping stone for more advanced ROV projects in the future. By following these guidelines, you can establish a dependable tether for your ROV, enabling seamless communication and power transfer during your underwater expeditions. By diligently following these detailed instructions and implementing your custom dimensions, you will be well on your way to constructing a personalized Seafox-design ROV. After a year of dedicated effort and overcoming various challenges, the time had come to put my ROV to the test in a real-world setting. I soon found out that many ROVs use a vectored thruster technique for direction control. Carefully attach these end caps to the ends of the PVC pipes. Double-click on "Video Capture Device. Neat and Efficient Tether: Take your time to ensure the heat-shrink tube sections are properly placed. I may, if I get real ambitious, try to add a grabber arm.
