What is the primary function of a servo motor in robotics?

The primary function of a servo motor in robotics revolves around providing precise control of angular position. Servo motors are designed to allow for accurate positioning, which is crucial in many robotic applications where specific movements are required. They operate based on feedback systems, enabling them to adjust their position with high accuracy. This capability makes them ideal for tasks where precise angles and movements are necessary, such as in robotic arms, camera gimbals, and automated machinery.

In contrast, other options focus on different aspects of motion or functionality. The option related to increasing linear speed does not accurately describe the specialized role of servo motors, which prioritize positional accuracy over speed. Storing energy for motion is a characteristic associated more commonly with components like springs or flywheels rather than servo motors. Similarly, operating in an open loop refers to control systems that do not use feedback to adjust their performance, while servo motors typically function in a closed-loop system to achieve their precise control.
