1. Which of the following best describes a robot’s degrees of
freedom (DOF)?
a) The robot’s speed and payload capacity
b) The number of independent axes of motion the robot has
c) The robot’s programming language
d) The type of end-effector it uses
b) The number of independent axes of motion the robot has
Rationale: Degrees of freedom refer to the number of independent
movements a robot can make. For instance, a 6-DOF robot can move
in six independent directions, typically three translational and three
rotational.
2. In industrial robots, the teach pendant is primarily used for:
a) Mounting the robot to the floor
b) Programming and manually guiding the robot
c) Measuring the robot’s payload
d) Controlling the robot’s internal hydraulics
b) Programming and manually guiding the robot
Rationale: The teach pendant is a handheld device that allows
,operators to teach and program robots by manually moving them
through desired positions and sequences.
3. Which type of robot is most commonly used for arc welding?
a) SCARA
b) Cartesian
c) Articulated
d) Delta
c) Articulated
Rationale: Articulated robots with multiple rotary joints provide the
flexibility needed for precise welding along complex paths.
4. In robot programming, point-to-point (PTP) motion is best
described as:
a) Moving along a precise path between two points
b) Moving from one position to another without controlling the
path
c) Continuous movement along a pre-defined trajectory
d) A motion that requires inverse kinematics
b) Moving from one position to another without controlling the path
Rationale: PTP motion moves the robot from a start to an endpoint
without guaranteeing the path between them, focusing on endpoint
accuracy.
5. A payload rating of a robot refers to:
a) The maximum speed the robot can reach
b) The maximum weight it can carry or manipulate safely
c) The robot’s maximum reach
d) The number of programmed positions
,b) The maximum weight it can carry or manipulate safely
Rationale: Payload rating specifies the maximum load a robot can
handle without compromising precision or safety.
6. Which robot configuration is best suited for pick-and-place tasks
at high speed?
a) Articulated
b) SCARA
c) Cartesian
d) Cylindrical
b) SCARA
Rationale: SCARA robots excel in horizontal pick-and-place tasks with
high speed and repeatability due to their rigid structure and limited
DOF.
7. The process of calibrating a robot ensures:
a) The robot’s internal software is updated
b) The robot moves accurately according to programmed
coordinates
c) The robot consumes less power
d) The end-effector weight is reduced
b) The robot moves accurately according to programmed coordinates
Rationale: Calibration aligns the robot’s coordinate system with the
physical workspace, ensuring precise motion and positioning.
8. Which programming method uses pre-recorded points to define
the robot’s path?
a) Offline programming
b) Teach pendant programming
c) Ladder logic programming
d) Sensor-based programming
, b) Teach pendant programming
Rationale: Teach pendant programming involves moving the robot
manually to record positions, which are later used to define the path.
9. Inverse kinematics in robotics is used to:
a) Determine the speed of the robot
b) Calculate joint angles to achieve a desired end-effector position
c) Program safety zones
d) Estimate the robot’s payload capacity
b) Calculate joint angles to achieve a desired end-effector position
Rationale: Inverse kinematics solves for the joint parameters needed
to place the robot’s end-effector at a specific location and orientation.
10. Which sensor type is commonly used for collision detection
in industrial robots?
a) Proximity sensor
b) Vision sensor
c) Force/torque sensor
d) Encoder
c) Force/torque sensor
Rationale: Force/torque sensors measure forces applied to the robot’s
joints or end-effector, allowing the system to detect collisions and
prevent damage.
11. A robot’s reach refers to:
a) The distance it can move in a single motion
b) The maximum distance from its base to the farthest point its
end-effector can reach
c) The size of its workspace
d) The number of joints it has
