• C. LARS
• D. Thruster

Answer: (B)

Hydraulic systems provide the power and precision needed for a manipulator to perform tasks such as collecting samples, turning valves, and deploying tools. A manipulator is essentially a robotic arm that uses hydraulic actuators at its joints to convert fluid pressure into controlled, multi-axis movement. The high force and smooth, precise positioning of hydraulic actuators are ideal for delicate sampling, accurate valve operation, and tool deployment in tight or challenging environments. Pumps and other components supply the fluid power, but the device that actually interacts with objects and performs the tasks is the manipulator. Thrusters are for propulsion, not manipulation, and LARS is a deployment/recovery system rather than a manipulator.
