Hello, my team and I recently assembled a Blue ROV2 and established QGround Control. After running tests out of water we tested it in a small pool. Robot will descend, ascend, yaw and move side to side correctly.
However, it will not move forward and backward. We pulled it out of the water to see how it would run on dry land, and it appears that only 2 motors are working at a time. Going forward motors 1 and 4 would run, and going backward motors 2 and 3 would run. When we use depth hold mode, it would hold for a moment then begin to roll to the side. We believe these are issues with calibration and not motor position.
Also, we set up and calibrated the Subsea Gripper. It was working fine during our first test 2 days ago, but now it has stopped working. It would make a clicking sound when we hit the button, but would not move.
Is there any advice you can offer to remedy these issues?
