ANSWER: electric motors [accept DC motors]

[10m] A DC motor, a position potentiometer, and a specialized microcontroller form a common type of these devices, which are defined as precise motor-driven components with a positive feedback mechanism.

ANSWER: servomotors

[10h] Controlling hobby servos typically uses this technique, which converts any analog signal into a rectangular wave with a variable duty cycle.

ANSWER: pulse-width modulation [or PWM; accept pulse-duration modulation or PDM; accept pulse-length modulation or PLM]
