Thank for the kind words! We agree it is awesome for us to see just how far the BlueROV2 has reached around the world, and what manner of cool things are being accomplished with it.
We agree that tools and other instruments are necessary to expand the capabilities of the BlueROV2, and definitely have plans for these in the future. We are working on actuators and a gripper, but there is a lot of work to be done, and unfortunately it is a lot more difficult than just waterproofing an off the shelf servo. We are definitely aware that there is a lot of demand for such things, and they are on the list!
