Diagnostics and Repair - Control
Control problems can occur due to a communications problem, a hand controller problem, a problem with an ROV subsystem, poorly adjusted buoyancy, or a physical problem like a stuck tether or fouled propeller.
VideoRay Cockpit instruments can confirm that a hand controller input is being received. If the instrument does not indicate a controller input, such as the camera indicator does not move when you press the camera tilt button, then check to make sure the hand controller is plugged in. You can also check whether the hand controller is recognized by Windows. You can check if the hand controller is recognized by Windows using the Game Controller application in the Windows Control Panel.
If the hand controller is working, but you cannot pilot the ROV, check for a loose or fouled propeller. If the propellers are clear, the problem could be a thruster motor or motor controller. If the problem is vertical control, then you might need to adjust the ballast.
If the ROV can be piloted, but another subsystem, like camera tilt, is not functioning, verify the hand controller function as listed above, and then suspect the subsystem.
See the Control Sensitivity and Systems Tuning section of the VideoRay Cockpit Guide for more information about adjusting the responsiveness and power settings of the thrusters.
