1. What is the primary function of a robotic end effector?
A. To power the robot’s joints
B. To provide sensory feedback
C. To interact with the robot’s environment
D. To serve as the robot’s central processor
The end effector is the part of a robot designed to interact physically
with objects in its environment, such as grippers or tools.
2. In a typical industrial robot, which axis of motion allows the robot arm
to move up and down?
A. X-axis
B. Z-axis
C. Y-axis
D. W-axis
The Z-axis corresponds to vertical movement, allowing up and down
motion in a three-dimensional coordinate system.
3. What type of sensor is commonly used to detect the proximity of a
metal workpiece without physical contact?
A. Optical sensor
B. Ultrasonic sensor
C. Inductive proximity sensor
D. Capacitive proximity sensor
Inductive proximity sensors detect metallic objects by generating an
electromagnetic field without contact.
,4. Which control strategy adjusts robot output continuously based on
feedback to reduce error between actual and desired position?
A. Open-loop control
B. Closed-loop control
C. Feedforward control
D. Dead-reckoning control
Closed-loop control uses feedback to compare actual outputs with
desired values and corrects discrepancies.
5. What does PWM stand for in robotics motor control?
A. Pulse Width Monitoring
B. Pulse Width Modulation
C. Power With Measurement
D. Position With Memory
Pulse Width Modulation is a method of controlling motor speed by
varying pulse durations in a signal.
6. A robot’s teach pendant is primarily used for what purpose?
A. Monitoring sensor outputs
B. Programming and controlling the robot manually
C. Measuring joint torque
D. Cooling the robot controller
A teach pendant is a handheld device that allows technicians to
program and manually move the robot through desired positions.
7. Which type of actuator is most common in industrial robotic joints?
A. Hydraulic actuator
B. Pneumatic actuator
C. Electric servo motor
D. Shape memory alloy actuator
Electric servo motors are widely used in industrial robots for precise
motion control.
8. What safety device immediately shuts down robot motion when a
perimeter is breached?
A. Limit switch
B. Light curtain
C. Encoder
D. Thermal fuse
, Light curtains create an invisible barrier; when broken, they trigger
an immediate stop to prevent injury.
9. What describes the reachable workspace of a robot?
A. The maximum payload capacity
B. The robot’s control resolution
C. The volume in space the robot can access
D. The robot’s operating temperature range
Reachable workspace refers to all positions the robot’s end effector
can physically reach.
10. What is ‘kinematics’ in the context of robotics?
A. Study of force and torque
B. Study of energy consumption
C. Study of motion without regard to forces
D. Study of electrical wiring
Kinematics focuses on motion parameters such as position, velocity,
and acceleration without considering forces.
11. Which digital communication protocol is widely used in
industrial automation for real-time control?
A. HTTP
B. FTP
C. EtherCAT
D. SMTP
EtherCAT is a high-performance industrial Ethernet protocol designed
for real-time control applications.
12. What component provides feedback on a joint’s angular
position?
A. Torque sensor
B. Thermistor
C. Encoder
D. Potentiometer
An encoder measures rotational position and is commonly used for
joint position feedback.
13. What is the purpose of a robot’s teach mode?
A. To test safety circuits
B. To record joint positions for tasks
