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.

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.
