vex motors have built - in ______________ that count rotations or degrees. sensors gears ports encoders
Answer
Brief Explanations:
Encoders are used to measure the position, rotation, or degrees of a motor - related component. VEX motors have built - in encoders for this purpose. Sensors detect other types of environmental or mechanical changes, gears are for mechanical power transmission and speed/ torque modification, and ports are for connecting components.
Answer:
D. encoders
