1. What is the primary function of a robotic end effector?
a) To power the robot
b) To interact with the environment
c) To process data
d) To navigate the robot
Rationale: The end effector is the device at the end of a robotic arm
designed to interact with objects, such as grippers, welders, or suction
cups.
2. Which type of robot movement allows a robotic arm to move in a
straight line between two points?
a) Joint interpolation
b) Linear interpolation
c) Circular interpolation
d) Point-to-point motion
Rationale: Linear interpolation controls the robot to move its end
effector in a straight line from one point to another.
3. In robotics, what does DOF stand for?
a) Direction of Function
b) Degrees of Freedom
, c) Digital Output Frequency
d) Direction of Force
Rationale: Degrees of Freedom indicate the number of independent
movements a robot can perform.
4. Which sensor type is most commonly used for object detection in
robotic arms?
a) Thermocouples
b) Strain gauges
c) Proximity sensors
d) Potentiometers
Rationale: Proximity sensors detect the presence or absence of objects
without physical contact.
5. What is the purpose of a teach pendant in industrial robotics?
a) To calibrate sensors
b) To program and control the robot manually
c) To power the robot
d) To measure torque
Rationale: A teach pendant allows operators to manually guide the
robot and program motion sequences.
6. Which type of robot is typically used for spot welding in
automotive manufacturing?
a) SCARA robot
b) Articulated robot
c) Delta robot
d) Cartesian robot
, Rationale: Articulated robots with multiple rotary joints are ideal for
welding applications due to their flexibility.
7. What is a PLC used for in a robotic system?
a) To control robotic operations and I/O devices
b) To measure robot speed
c) To lubricate joints
d) To provide mechanical support
Rationale: A Programmable Logic Controller (PLC) manages robot
actions and communicates with sensors and actuators.
8. Which of the following is a benefit of using a collaborative robot
(cobot)?
a) Requires full safety fencing
b) Can safely work alongside humans
c) Only performs heavy payload tasks
d) Cannot be reprogrammed
Rationale: Cobots are designed with safety features to allow interaction
with humans in shared workspaces.
9. What type of actuator is most commonly used in industrial
robots?
a) Hydraulic
b) Pneumatic
c) Electric motor
d) Manual crank
Rationale: Electric motors are precise, reliable, and widely used in
industrial robotic arms.
