Which item is an auxiliary tooling of an ROV?

• A. Thrusters
• B. LARS
• C. Cutting tools
• D. Hydraulic motor

Answer: (C)

When thinking about an ROV, distinguish between what moves the vehicle and what performs the actual underwater tasks. Thrusters are the propulsion system that steers and moves the ROV, while LARS is hardware used to launch and recover the vehicle. A hydraulic motor is a drive component that powers actuators or tools, not a tool itself. Auxiliary tooling refers to the end-effectors and attachments that carry out interventions—things like cutters, saws, or graspers mounted on the manipulator.

Cutting tools fit this role perfectly because they are the specialized instruments attached to the ROV to perform a work task underwater. They are the actual tooling used to interact with the environment, rather than something that moves the ROV or supports its deployment.
