Certified Robot Integrator Ultimate Exam | Latest Verified
Questions and Detailed Answers
OVERVIEW DESCRIPTION
This comprehensive set of multiple-choice questions is designed for the Certified
Robot Integrator Ultimate Exam, a rigorous assessment that evaluates advanced
competency in industrial robot system integration. The exam covers a broad spectrum
of topics including international safety standards (ANSI/RIA R15.06, ISO 10218, ISO
13849), risk assessment and performance level determination, collaborative robot
operation modes, safeguarding device integration, robot kinematics and programming,
end-of-arm tooling design, functional safety with SIL/PL, and commissioning with
validation procedures. Questions probe practical application of safety-rated functions
like Safe Torque Off, safely-limited speed, and safety-rated monitored stop, as well as
cell design, network protocols, and troubleshooting, ensuring a candidate’s readiness
to design, verify, and maintain safe, compliant robotic systems.
QUESTION 1
What is the primary standard governing industrial robot safety in North America?
A. ISO 13849-1
B. ANSI/RIA R15.06
C. ISO 10218-1
D. IEC 62061
CORRECT ANSWER: B
EXPERT RATIONALE: ANSI/RIA R15.06 is the adopted North American standard for
industrial robot safety, harmonizing ISO 10218 with regional requirements.
QUESTION 2
Which ISO standard specifies safety requirements for industrial robots?
A. ISO 12100
B. ISO 10218-1
,2|Page
C. ISO 13849-2
D. ISO 13850
CORRECT ANSWER: B
EXPERT RATIONALE: ISO 10218-1 addresses the robot itself, while ISO 10218-2 covers
robot systems and integration.
QUESTION 3
In a robot risk assessment, what is the first step according to ISO 12100?
A. Risk evaluation
B. Hazard identification
C. Risk reduction
D. Determination of limits of machinery
CORRECT ANSWER: D
EXPERT RATIONALE: Risk assessment begins by defining the machine’s limits, including
use, space, time, and environmental constraints, before identifying hazards.
QUESTION 4
Which collaborative robot operation mode requires the robot to stop when a human
enters the collaborative space?
A. Power and force limiting
B. Speed and separation monitoring
C. Safety-rated monitored stop
D. Hand guiding
CORRECT ANSWER: C
,3|Page
EXPERT RATIONALE: Safety-rated monitored stop stops all hazardous motions while the
operator is in the collaborative workspace, resuming automatically once the person
leaves.
QUESTION 5
What does a “deadman switch” on a teach pendant require to maintain robot motion?
A. Continuous pressure only
B. Release and re-press within 2 seconds
C. Three-position enabling device held in center position
D. Dual-channel signal without time limit
CORRECT ANSWER: C
EXPERT RATIONALE: A three-position enabling device allows motion only when held in
the middle position; fully released or fully depressed stops the robot.
QUESTION 6
Which performance level (PL) according to ISO 13849-1 corresponds to the highest risk
reduction?
A. PL a
B. PL c
C. PL d
D. PL e
CORRECT ANSWER: D
EXPERT RATIONALE: PL e provides the greatest risk reduction, with an average
probability of dangerous failure per hour of ≥10⁻⁸ to <10⁻⁷.
QUESTION 7
In functional safety, what does “SIL” stand for?
, 4|Page
A. Safety Integration Level
B. Safety Integrity Level
C. System Integrity Limit
D. Standard Integration Logic
CORRECT ANSWER: B
EXPERT RATIONALE: Safety Integrity Level (SIL) is a measure of safety system
performance, defined in IEC 61508 and used in robotics.
QUESTION 8
Which type of robot singularity occurs when axes 4 and 6 of a six-axis articulated robot
become aligned?
A. Shoulder singularity
B. Elbow singularity
C. Wrist singularity
D. Overhead singularity
CORRECT ANSWER: C
EXPERT RATIONALE: Wrist singularity happens when joint 5 approaches zero, causing
axes 4 and 6 to align, losing one degree of freedom.
QUESTION 9
What is the purpose of a User Frame in robot programming?
A. Define the tool center point
B. Shift the robot’s world coordinate system
C. Align with a workpiece or fixture
D. Set payload mass
CORRECT ANSWER: C
