Fresh hacks every day
[Eirik] wrote in to share the build log for the third iteration of his underwater ROV. The first two project were completed and tested (you may remember reading about it back in January), but both had issues that caused general failure. Most notably, the introduction of water where he didn't want it. But this time around he seems to have gotten everything right, successfully taking this little guy … [Read more...]
[Byrel Mitchell] wrote in to share some details on this water glider which he has been working on with his classmates at the Nonlinear Autonomous Systems lab of Michigan Technological University. As its name implies, it glides through the water rather than using propulsion systems typically found on underwater ROVs. The wings on either side of the body are fixed in place, converting changes … [Read more...]
[Brane] built an underwater ROV from LEGO mindstorm parts. Look closely at this image and you should notice something missing. The tether that normally carries power and control lines from an ROV to the surface is missing. This is a wireless solution that lets him control the device using an Xbox controller. The video after the break shows about five minutes of test drive footage. [Brane] has a … [Read more...]
This rig looks so good it's hard to believe this is the first ROV that [DZL] has ever built. It houses an HD camera which feeds the display at the operator's station. You can see the controller to the left of that screen which uses a joystick and buttons to pilot the underwater vessel. In order to simplify construction, [DZL] decided not to use propellers. The problem with that technique is … [Read more...]
Purdue University's IEEE branch participated in this year's Marine Advanced Technology Education Center Competition, taking second place for the Hybris ROV seen above. The competition included several compulsory functions, including the ability to cap an underwater oil well, collect biological samples, and take water samples at depth. What they came up with is a quick and agile watercraft that … [Read more...]
[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 … [Read more...]
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. … [Read more...]
