Control Diagnostics

Control problems are usually manifested as an inability to control the ROV in the desired motions. This can be due to system problems or environmental factors such as the ROV being stuck or running out of tether.

Control problems can also arise when a system component has been improperly installed or configured or fails during operations. Examples include:

• Improperly installed propeller
• Fouled thruster
• Faulty or improperly configured thruster
• Faulty or improperly configured hand controller
• faulty or improperly configured DVL

Control problems are divided into manual flight, auto pilot modes like Auto Heading or Auto Depth, or fully autonomous dynamic positioning, course following and orbiting.

For manual flight, check the hand controller and the thrusters.

For dynamic positioning, first verify manual flight then check the control interfaces are selected properly, the verify DVL lock.
