1. Which of the following is the primary function of an industrial
robot?
A. Perform manual labor
B. Replace human operators entirely
C. Automate repetitive tasks
D. Increase factory floor size
Rationale: Industrial robots are primarily designed to automate
repetitive, precise, or hazardous tasks to improve efficiency and
consistency in manufacturing.
2. What type of robot joint allows rotational movement around a
single axis?
A. Prismatic joint
B. Cylindrical joint
C. Revolute joint
D. Spherical joint
Rationale: A revolute joint provides rotation around a single axis,
similar to a hinge, and is common in robotic arms.
, 3. Which coordinate system is most commonly used for
programming industrial robots?
A. Polar
B. Cartesian
C. Cylindrical
D. Spherical
Rationale: Cartesian coordinates (X, Y, Z) allow precise positioning in
three-dimensional space and are widely used in industrial robotics
programming.
4. The teach pendant is primarily used to:
A. Maintain robot power
B. Program and manually control the robot
C. Monitor temperature
D. Replace the robot controller
Rationale: A teach pendant is a handheld device that allows operators
to teach positions, program movements, and manually control the
robot.
5. Which safety feature prevents a robot from moving if a person
enters the work zone?
A. Limit switch
B. Emergency stop
C. Safety light curtain
D. Robot brake
Rationale: Safety light curtains detect objects in the robot’s work area
and stop movement to prevent injury.
6. What does payload refer to in robotics?
A. Maximum speed of the robot
B. Maximum weight the robot can carry
, C. Maximum number of programmed points
D. Size of the robot arm
Rationale: Payload is the weight a robot can safely handle without
compromising performance or safety.
7. Which type of robot is most suitable for pick-and-place tasks?
A. SCARA
B. Cartesian
C. Delta
D. All of the above
Rationale: SCARA, Cartesian, and Delta robots are all commonly used
for high-speed pick-and-place operations due to their precision and
speed.
8. Servo motors in industrial robots are primarily used to:
A. Provide energy to the plant
B. Control joint movement precisely
C. Cool the robot
D. Connect the robot to the network
Rationale: Servo motors provide accurate position, speed, and torque
control, enabling precise robotic movements.
9. When a robot repeats a motion inaccurately, which parameter is
most likely at fault?
A. Payload
B. Speed
C. Calibration
D. Teach pendant
Rationale: Calibration ensures the robot’s physical movements match
the programmed positions; misalignment can cause inaccuracies.
