Related Question 1
Which of these is an example of a robot mobility mechanism?
  • A. Stepper motor
  • B. Hovercraft propulsion
  • C. USB interface
  • D. Ultrasonic sensor
Correct Answer: B
Explanation:
Hovercraft propulsion (or wheels, tracks) provides movement; the stepper motor is the actuator, and the ultrasonic is the sensor.
Related Question 2
What sensor does a robot use for mapping its surroundings using laser beams?
  • A. Gyroscope
  • B. Lidar
  • C. GPS
  • D. Thermometer
Correct Answer: B
Explanation:
LiDAR uses laser pulses to measure distances and help create a map of the environment.
Related Question 3
Why might a roboticist use sensors like accelerometers or gyroscopes?
  • A. To convert electrical energy into motion
  • B. To measure motion, orientation, and acceleration
  • C. To provide power to the robot
  • D. To store data
Correct Answer: B
Explanation:
Accelerometers and gyroscopes measure acceleration and rotational motion, respectively, to support the robot's navigation and balance.
