INSTANTANT DOWNOAD PDF
1. Which of the following sensors is commonly used to detect distance
in industrial robots?
A) Infrared sensor
B) Ultrasonic sensor
C) Gyroscope
D) Thermocouple
Rationale: Ultrasonic sensors measure distance by sending sound waves
and detecting their echo, making them ideal for obstacle detection.
2. What is the main purpose of a robot's end effector?
A) To control the robot's speed
B) To interact with the environment
C) To provide power to motors
D) To store programming data
Rationale: The end effector is the “tool” at the robot’s arm, such as a
gripper, welding torch, or sensor, enabling the robot to perform tasks.
3. Which type of robotic joint provides rotational motion?
A) Prismatic joint
B) Revolute joint
C) Spherical joint
D) Cylindrical joint
,Rationale: Revolute joints allow rotation around an axis, which is
fundamental for robot arm articulation.
4. Which programming language is most commonly used in industrial
robot programming?
A) Python
B) RAPID
C) Java
D) SQL
Rationale: RAPID is ABB’s proprietary language for controlling industrial
robots, widely used in manufacturing.
5. What is the main advantage of using servomotors in robotics?
A) Low cost
B) Precise position control
C) High-temperature resistance
D) Simple mechanical design
Rationale: Servomotors provide accurate control of angular or linear
position, essential for precision tasks.
6. In robotics, what does “DOF” stand for?
A) Digital Output Function
B) Degrees of Freedom
C) Direction of Force
D) Data Optimization Framework
Rationale: DOF refers to the number of independent movements a robot
can make, such as rotating or extending joints.
7. Which type of robot is best suited for assembly line operations in
manufacturing?
, A) SCARA robot
B) Delta robot
C) Mobile robot
D) Humanoid robot
Rationale: SCARA robots are specialized for fast, precise horizontal
assembly tasks.
8. What is the purpose of PID control in robotics?
A) To optimize battery usage
B) To provide closed-loop motion control
C) To generate AI-based decisions
D) To connect sensors to the controller
Rationale: PID (Proportional-Integral-Derivative) controllers regulate
motors by correcting errors between desired and actual positions.
9. Which type of robotic vision sensor uses structured light to measure
depth?
A) LIDAR
B) Infrared camera
C) Stereo camera
D) 3D structured light sensor
Rationale: Structured light projects patterns onto objects and measures
distortion to compute depth.
10. Which safety standard applies to industrial robots in the U.S.?
A) ISO 9001
B) ANSI/RIA R15.06
C) OSHA 300
D) IEEE 802.11
