BlueROV2 Frame Updates

By: Jonathan N., Mechanical Engineer at Blue Robotics

Hello everyone! Today we’ve got a few BlueROV2 updates to announce. We’re always working to make our products better, especially the BlueROV2, and these small changes make a big difference in the feel of the ROV’s frame. Here are the changes.

Minor updates to the BlueROV2 frame.

We have rounded the edges everywhere on the frame. Not only does this look awesome, but it makes the ROV much more comfortable to carry by hand.

We have changed the threaded inserts from press-in inserts to captured inserts. We made this change to make the frame stronger and more rigid. This makes it much more ruggedized and resistant to damage. There are more pictures on the BlueROV2 product page.

Last, there are now two sets of vectored thruster mounting holes; the original set at 45° and a new set at 30°. Mounting the thrusters at 30° instead of 45° increases the available forward thrust by 22% but reduces lateral thrust by 22%. This configuration is better for missions that require flying forward quickly or for a long time. We wanted this option to speed up the ROV when searching for shipwrecks or other targets. You rarely need to move laterally at full speed, so the loss of lateral thrust is barely noticeable. In any case, the original holes are still available to give you options!

The new frame is now available separately on our store for anyone who is interested. This frame kit comes with all of the HDPE panels, the anodized aluminum enclosure cradles, and all of the required hardware.

New Stable Release of BlueROV2 Software

Newest QGroundControl release.

Hello everyone! Today we’re proud to announce an updated release of the BlueROV2’s core software, which includes ArduSub, Companion, QGroundControl. This is our second big software update, and this time it can be performed without opening the electronics enclosure!

Notable changes in this update are:

  • Ability to display camera tilt angle, lights level, tether turns and more in QGC
  • GPS input support in Companion, including support for the Water Linked Underwater GPS Developer Kit
  • Fewer default pre-arm checks
  • Acceptable compass calibration threshold has been relaxed
  • Pilot input failsafe timeout increased from 1 second to 3 seconds (‘Lost manual control’ message)
  • Gyro calibration is disabled at boot by default
  • Support for the Bar100 pressure sensor
  • Companion login is changed to:
    • user: pi
    • password: companion
  • Allow selecting a custom image to display in the QGC ui in place of the ‘ArduSub’ logo
  • Many other various bugfixes, feature additions, and improvements, reference the release notes below for a comprehensive list of changes

We’ve done a lot of work to get this point and special credit goes to Jacob and Daniel, our primary Blue Robotics software developers. We strongly encourage all BlueROV2 users to upgrade to this newest software update. Please visit the full forum topic for update instructions.

New Products! Low-Light HD USB Camera and Bar100 Depth/Pressure Sensor

Hello, friends! It’s a lovely day to #godeep, and today we’re stoked to bring a couple of capable products into the picture.

Check out the New Product Video on Youtube:

Let’s bring our focus to the new Low-Light HD USB Camera. This camera is ideally suited to use underwater with excellent low-light performance, good color handling, and onboard video compression. A specially-chosen wide-angle, low distortion lens provides excellent picture quality on the ROV. With a 3D printed camera mount, it is a drop in replacement for the Raspberry Pi Camera on the BlueROV2.

Next up we have the Bar100 Depth/Pressure Sensor. It’s built around the Keller LD Series pressure/temperature sensor, which communicates via I2C communication, just like the Bar30 Pressure/Depth Sensor. It can measure up to 100 bar – that’s over 1000 meters water depth! It has a pressure resolution of 3 mbar, providing a depth measurement resolution of 3 cm in the water column.
