1. What is the primary function of an industrial robot in
manufacturing?
A. To replace all human workers
B. To automate repetitive or hazardous tasks
C. To design production layouts
D. To manage supply chains
Answer: B
Rationale: Industrial robots are primarily designed to perform
repetitive, precise, or dangerous tasks, improving efficiency and safety
rather than fully replacing humans or handling management-level
functions.
,2. Which component is considered the "brain" of an industrial robot?
A. Servo motor
B. End effector
C. Controller
D. Teach pendant
Answer: C
Rationale: The controller processes instructions, executes programs,
and coordinates all robot movements and actions.
3. What is the purpose of a robot end effector?
A. Power the robot arm
B. Execute software commands
C. Interact with the environment
D. Store program memory
Answer: C
Rationale: End effectors are tools such as grippers or welders that
allow the robot to physically interact with objects.
4. Which axis typically defines left-right movement in a Cartesian
robot system?
,A. X-axis
B. Y-axis
C. Z-axis
D. R-axis
Answer: A
Rationale: In Cartesian coordinate systems, the X-axis represents
horizontal left-right movement.
5. What does “degrees of freedom” refer to in robotics?
A. Number of robot programs stored
B. Number of independent movements a robot can perform
C. Speed of the robot controller
D. Number of sensors attached
Answer: B
Rationale: Degrees of freedom describe how many independent axes
or motions a robot can perform.
6. Which type of robot uses linear axes for movement?
A. SCARA robot
B. Cartesian robot
, C. Articulated robot
D. Delta robot
Answer: B
Rationale: Cartesian robots move along straight X, Y, and Z axes using
linear motion systems.
7. What is a teach pendant used for?
A. Cooling the robot
B. Programming and manually controlling the robot
C. Powering the robot
D. Measuring payload weight
Answer: B
Rationale: A teach pendant allows operators to manually move the
robot and input programs.
8. Which sensor is commonly used for object detection without
contact?
A. Pressure sensor
B. Proximity sensor
