A special type of motor used to drive many robots is called a ________.

• A. Servo motor
• B. Robotic motor
• C. Mimic motor
• D. Select-arm motor

Answer: (A)

A servo motor is a special type of motor used to drive many robots because it provides precise, repeatable position control. It combines a motor with a gearbox, a feedback sensor (like a potentiometer or encoder), and control electronics, creating a closed-loop system. When you command a servo to move to a specific angle, the controller compares the desired position with the actual position and adjusts the motor output until the target is reached. This built-in feedback and control make servo motors ideal for robot joints and arms where accurate placement and predictable motion are essential. The other terms aren’t standard names for a motor with this level of feedback and control, so they don’t describe the same capability as a servo motor.
