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!

Mounting options for 30° angle to forward.

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.


BlueROV2 Now Comes More Assembled!

By: Jonathan N., Mechanical Engineer at Blue Robotics

Hey guys! Since we started shipping BlueROV2s in August of 2016, we have been making improvements to the kit to make it easier and less time consuming to assemble. We have been incorporating some of the improvements quietly as we went, but we have made a couple of big changes that we would like you to know about.

First we have updated the assembly instructions to reflect the fact that much less assembly is required on your end. The new instructions are 35% shorter than the old instructions! Here’s everything that has changed. Some of these changes happened months ago and some of them happened recently.

  • ArduSub 3.4 (stable version) comes preinstalled on the Pixhawk.
  • Our recommended parameters come preinstalled on the Pixhawk.
  • ArduSub Raspbian comes loaded on the SD card for the Raspberry Pi 3.
  • The Fathom-X Tether Interface board comes installed on the electronics tray and all of the wiring has been completed.
  • The Raspberry Pi and Pixhawk come installed on the electronics tray with most of the wiring completed.
  • The Pixhawk Power Module is installed and the wiring is completed.
  • The ESCs now come with all of the wiring completed.
  • Three of the thrusters now come with the counter-clockwise propellers pre-installed.
  • The camera, Pixhawk, Raspberry Pi, and Fathom-X connections have all been tested.
  • The SOS Leak Sensor is included and installed onto the electronics tray!

If reading a bunch of bullet points isn’t your thing. Here are some pictures comparing the first batch to what we are doing now.

If you received your kit prior to March, you might still want to use the original instructions, which are still available here.
