1. What is the primary responsibility of a robotics technician in an
industrial environment?
A. Designing marketing strategies for robotic products
B. Installing, maintaining, troubleshooting, and repairing robotic
systems
C. Writing only high-level artificial intelligence algorithms
D. Manufacturing raw materials used in robots
Answer: B. Installing, maintaining, troubleshooting, and repairing
robotic systems
Rationale: A robotics technician is responsible for the practical
operation of robotic equipment, including installation, calibration,
preventive maintenance, diagnostics, repairs, and system integration.
Engineers typically handle advanced design, while technicians ensure
reliable field operation.
2. Which component acts as the "brain" of an industrial robot by
executing programmed instructions?
A. End effector
B. Controller
1
,C. Gearbox
D. Servo motor
Answer: B. Controller
Rationale: The robot controller processes programs, receives sensor
feedback, controls motion commands, and coordinates communication
between robotic components. It functions as the central processing
unit of the robotic system.
3. A six-axis articulated robot is commonly used because it provides:
A. Limited movement with only linear motion
B. Human-like flexibility and multiple degrees of freedom
C. Operation without programming
D. Elimination of all safety requirements
Answer: B. Human-like flexibility and multiple degrees of freedom
Rationale: Six-axis articulated robots provide rotational movement
similar to a human arm, allowing complex tasks such as welding,
assembly, painting, and material handling.
4. What is the purpose of a robot’s end effector?
A. To supply electrical power
B. To control network communication
C. To interact with the workpiece or environment
D. To cool the robot controller
Answer: C. To interact with the workpiece or environment
Rationale: The end effector is the tool attached to the robot arm, such
as a gripper, welding torch, vacuum cup, or machining tool. It allows
the robot to perform specific tasks.

,5. Which sensor type is commonly used to detect the position of a
robotic joint?
A. Encoder
B. Thermostat
C. Pressure regulator
D. Fuse
Answer: A. Encoder
Rationale: Encoders provide feedback about motor position, speed,
and direction. They are essential for accurate robotic movement and
closed-loop control.
6. What is the main purpose of preventive maintenance on robotic
systems?
A. Increase unexpected failures
B. Reduce downtime and extend equipment life
C. Remove safety systems
D. Eliminate programming requirements
Answer: B. Reduce downtime and extend equipment life
Rationale: Preventive maintenance involves inspections, lubrication,
calibration, and component replacement before failure occurs,
improving reliability and productivity.
7. In robotics, a degree of freedom (DOF) refers to:
A. The amount of electrical power consumed
B. Independent movements available to a robot
3
, C. Number of workers operating the machine
D. Size of the robot controller
Answer: B. Independent movements available to a robot
Rationale: Each degree of freedom represents an independent axis of
movement. More degrees of freedom provide greater flexibility and
positioning capability.
8. What programming method involves teaching a robot by
physically moving it through desired positions?
A. Lead-through programming
B. Machine learning only
C. Manual machining
D. Hydraulic programming
Answer: A. Lead-through programming
Rationale: Lead-through programming allows an operator to guide the
robot through movements that are recorded and later repeated
automatically.
9. What is the purpose of a robot calibration procedure?
A. Increase electrical consumption
B. Ensure accurate positioning and movement
C. Disable sensors
D. Remove software programs
Answer: B. Ensure accurate positioning and movement
Rationale: Calibration aligns the robot’s actual position with its
programmed coordinate system, improving accuracy and repeatability.
