[Eirik] wants to help inspire others to take on big projects to he sent in a link to his ROV project. He started it about one year ago and the image above shows the first generation. After the break you can see the video that the ROV captured during a couple of it’s initial voyages. They’re pretty clear and right off the bat you’ll see the little guy following a jellyfish. Like a lot of homebrew ROV’s [Eirik] is still searching for the right way to pass wires through the housing without leaks. He does okay so far, and has designed a nice cable spool for the topside tether, but some water does get in. He’s almost finished the second generation which re-designs the camera mount to aim downward so that what’s in frame is more interesting.

Next-Level Robotic Hijinx
Oberon is a wheeled remotely operated vehicle that [LucidScience] built based on an electric wheelchair. The detailed and helpful build log is valuable enough even before considering the vast potential of Oberon’s intended use: strutting around town, scaring the neighbours.
We’ve seen other ROVs before, of course, but none with the same kind of War of the Worlds “real-life invasion” kitch. Running down hapless pedestrians or raining hell upon your enemies are great and all, but once you’ve destroyed the surrounding population you’re out of laughs. Not so with Oberon, with which you can convince Mr. Nutcase down the road to go on wild quests for the glory of the new robot empire. The fun doesn’t stop there–enjoy the Hubbard side of life by starting a cult to worship the great Oberon and enjoy decades of financial payoff and moral depravity…all from the comfort of your own living room!
It would be wicked rad if we could move forward with this idea by combining the abilities of specialized ROVs like this camera-bot and this termite-killer-bot. Face it, who wouldn’t want a smooth-talking camera-snapping chemical-spraying avatar for christmas?
Remote Operated Underwater Vehicle
PVC hull, SLA batteries, Bilge Pumps, sounds like a good start to [Jimmy’s] ROV project. Paintball gun (as a BCD), dual live cameras paired with an Arduino making it internet controlled, all tethered with a fiber optic cable, sounds like [Jimmy’s] ROV got a whole lot more astounding.
While some very important parts have yet to be implemented, like the leak detectors, the project looks to be going quite smoothly. With updates promised, we can’t wait to watch this continue until the end.

Naval Academy’s AUV Team Project
[Daniel] sent us over to the blog for the Naval Academy’s Autonomous underwater vehicle entry for the AUVSI competition. You can follow along as they design, build, and test this years entry. It really looks like it would be fun to be the guy who gets to swim with them, like in the latest post in their blog. Their entry, named “Awkward turtle” can be seen above in orange, pictured with their 5th place winning previous entry.
Underwater ROV
[SpaceShipOne] has built this very nice looking under water ROV. It is still a work in progress, but nearly complete. This ROV is a fairly simple construction. most of the body parts are held together using zip ties. There’s no microcontroller and no custom boards. He’s using a radio control transceiver that was intended for airplanes to control some standard speed controllers and servos. For thrust, he pulled the motors out of some bilge pumps and fitted them with propellers. He’s only tested it once, but promises videos from the lake soon. He mentions [Jason Rollette] several times since [Jason] has done both simple and complex designs in the past.
Electric Screwdriver Robot Hand
Here’s an interesting grabber hand built for use on an ROV. This grabber is a novel use of a very common and extremely cheap electric screwdriver, that is probably found in everyone’s toolbox. It is also a great way to reuse that small electric screwdriver you have kicking around that uses proprietary batteries that are not worth replacing. Many of the ROV’s covered previously could benefit from such a powerful device built from very common materials off his parts list. Because the screwdriver was extremely cheap the designer chose not to completely seal the housing.
It seems like this simple design that could be used in many robotic projects and by simply changing the jaws could yield other creative uses. The first thing that comes to mind is to upsize this hack into something bigger and stronger. Either way, you might not want to get your fingers in there.
Underwater Camera Housings
Underwater cameras can produce some amazing photography, but who wants to pay for housing if you can make something yourself?
This underwater camera housing on Instructables doesn’t require a specific container, allowing you to choose anything you have around the house that’s watertight and large enough to fit your camera. A finger from a glove is added so you can still operated the controls. A similar project uses an insulated water jug, accommodating any camera that fits inside. Neither of these involve any camera mods.
