1. A robot is tasked with welding automotive body panels. Which type of
robot configuration is most suitable for high-speed, repetitive welding
along straight seams?
A. Cartesian
B. SCARA
C. Spherical
D. Cylindrical
SCARA robots provide high speed and precision for planar, repetitive
tasks like straight seam welding common in automotive assembly.
2. In industrial robotics, the term “degrees of freedom” refers to:
A. The robot’s power source efficiency
B. The number of tools a robot can hold
C. The number of independent axes of motion a robot possesses
D. The robot’s safety compliance rating
Degrees of freedom describe each independent axis along which a
robot can move, directly influencing its dexterity and reach.
3. A teach pendant is primarily used to:
A. Power the robot during maintenance
B. Program and manually guide the robot through positions
C. Test the robot’s safety circuits
, D. Replace the robot’s controller
Teach pendants allow operators to input waypoints and motion
sequences, facilitating hands-on programming of robot paths.
4. What sensor type is most appropriate for detecting the presence of a
metal component regardless of its color or surface finish?
A. Photoelectric sensor
B. Ultrasonic sensor
C. Inductive proximity sensor
D. Capacitive proximity sensor
Inductive sensors detect metal objects through changes in
electromagnetic fields and are unaffected by color or transparency.
5. A PLC controlling a robotic cell must respond to an input within 1 ms.
Which type of PLC scan mode ensures the fastest reaction time?
A. Sequential scan
B. Batch scan
C. Time-scheduled scan
D. Event-driven scan
Event-driven scanning prioritizes immediate reaction to input
changes, critical for fast safety and control responses in robotics
cells.
6. In robotic vision systems, “blob analysis” is used to:
A. Calibrate the camera lens
B. Detect color gradients
C. Identify and quantify connected regions of interest in an image
D. Filter out background noise by frequency
Blob analysis groups adjacent pixels into meaningful objects,
allowing the vision system to locate parts and features.
7. A robot arm moves a 5 kg payload. What is the kinetic energy when
the end effector is moving at 2 m/s? (Ignore gravity.)
A. 5 J
B. 10 J
C. 10 J
D. 20 J
Kinetic energy equals ½ * mass * velocity²; 0.5 * 5 * 2² = 10 Joules.
, 8. Which safety standard specifically addresses industrial robots and
robot systems?
A. ISO 9001
B. ISO 14001
C. ISO 10218
D. ISO 27001
ISO 10218 outlines safety requirements and guidelines for industrial
robot design, integration, and operation.
9. A gripper actuated by pneumatic cylinders requires 90 psi to operate.
If the compressor supply drops to 60 psi, what effect occurs?
A. Reduced grip force
B. Increased cycle time
C. Electrical overload
D. Overheating of the gripper
Insufficient air pressure in pneumatic systems results in lower output
force, reducing gripper effectiveness.
10. The teach/playback method of robot programming is best
described as:
A. Mathematical path optimization
B. Manual remote simulation
C. Recording physically guided motions to reproduce later
D. Off-line code generation
Teach/playback captures real motions via teacher pendant as the
operator guides the robot, then replays them automatically.
11. A robot wrist joint that rotates 180° about a single axis
contributes to which type of motion?
A. Linear
B. Planar
C. Rotary
D. Helical
Rotation about an axis is a rotary motion, fundamental for orienting
end effectors.
12. What does PWM stand for in motor control?
A. Pulse-Wide Modulation
B. Pulse-Width Modulation
