Adding two thrusters and changing their placement may seem like a small change, but it dramatically changes how the BlueROV2 handles in the water.
This video shows the ROV holding its orientation while the tether is pulled, demonstrating active pitch stabilization. The ROV can hold a steady camera view regardless of what’s going on. This stability control is really useful when you’ve attached large or multiple payloads to the ROV, such as sonars or a gripper, or when you’ve got a lot of tether in the water. The control system automatically corrects any unusual dynamics or imbalances.
Full six degree-of-freedom control for the BlueROV2 unlocks new maneuvering capabilities not usually found in ROVs of this size. Combining that with feedback-based stability control, you can orient the ROV in any position, hold that orientation, and continue piloting normally. This is cool and fun to pilot, of course, but it also opens up a lot of new operational possibilities when using tools or manipulators like the Newton Subsea Gripper.
