What is DJI cooking up? May 8, '19

DJI has updated their website with a countdown timer and a promise of something that will help you "UNLEASH YOUR OTHER SIDE".

The artwork for the teaser has a distinctly marine feel.

Could they be planning to launch an ROV? Or will it merely be a highly water resistant aerial drone?

We'll find out in 6 days.

If it's an ROV, maybe I'll be able to request a review unit? 🤔

OpenROV is now Sofar Ocean Technologies Mar 27, '19

OpenROV has merged with Spoondrift to form Sofar Ocean Technologies.

TechCrunch says that SolarCity co-founder Peter Rive is the driving force behind this merger and funding round.

Sofar currently has two main products, the Trident ROV and the Spotter ocean sensor. Not much information is available on any plans they might have to continue developing DIY ROV kits like the OpenROV 2.8.

OpenROV kits are sold out, but some parts still appear to be available on the OpenROV Store. Even the parts might not last for long, though, without an official commitment from Sofar.

Recent Video Reviews Feb 24, '19

Here are some recent video reviews of new ROVs, found on the youtube channel of Dustin Dunnill (definitely subscribe if you're interested in anything RC or ROV).

BlueRobotics BlueROV2 Unboxing/Testing Videos Jan 23, '18

Spotted some fantastic videos on Reddit of the BlueROV2 being unboxed, assembled, and tested. If you want to see the process, check these out.

BlueROV2 is a six-thruster ROV that can operate at a depth of 100 metres (300 feet). They also have an aluminum electronics enclosure that enables some models of the ROV to reach depths of 400 metres (1312 feet).

The base model costs $2,784 USD, although you'll probably want to include the tether and some lights (for a total cost of $3,483 USD). The ROV can be purchased from their store or from a number of distributors.

The Canadian distributor Schooner Labs provided the videos below.

Could Swarms of ROVs Make Submarines Obsolete? Oct 15, '17

This post from "The National Interest" recounts some details of a report that suggests Swarms of ROVs could make it so easy to detect nuclear submarines that their strategic purpose would be nullified. They mainly talk about airborne drones, but they also refer to undersea sonar-equipped "robot gliders" as an important tool in the submarine hunter's kit.

ROV Roundup (Oct 6th) Oct 6, '17

Mysterious 'Long-Arm Squid' is a Lovecraftian Horror of the Deep

Ten years ago, out in the middle of the Gulf of Mexico, a ROV employed by the Shell Oil Company was quietly moving through the chilled, dark waters of Alaminos Canyon. It was nearly 8,000 feet below the ocean’s surface, creeping along, inspecting the underwater area around the Perdido oil platform (the deepest offshore drilling site in the world) when its operator came upon a creature that inhabits both the depths of the ocean and the subconscious mind. The strange being from below was a “long-arm squid,” a 26-foot-long nightmare with elbowed tentacles and pulsating fins that undulate in a way that says: My kind were here for eons before you, and will be here for eons after you.

DIY 3D-Printed Kort Nozzle Thrust Test

And finally, here's a quick youtube video of a DIYer testing out the 3D-printed Kort nozzle. This 3D print, and many other useful ROV-related 3D objects, can be found at the Thingiverse link on the ROVCentral Resources Page.

Beebe and the Bathysphere Sep 23, '17

In the 1930s, William Beebe and Otis Barton used a large steel ball called the Bathysphere to set a submarine depth record that would stand for 30 years.

I recently learned of an initial failed test for their Bathysphere project, one that could have easily killed anyone in the sub as well as people on the surface. They sent the Bathysphere down to a depth of 3,000 feet - unmanned. When they pulled it back up, they could tell something was wrong. There was a small stream of water spraying out from inside it. What happened next was actually captured on video, but I encourage you to read the text description before watching, as it explains some of the things that are happening.
