1. What is the primary purpose of a robot manipulator’s forward
kinematics?
A. To calculate joint torques from end-effector forces
B. To determine the end-effector position given joint parameters
C. To compute the required joint parameters for a desired position
D. To optimize energy consumption during movement
Forward kinematics computes the position and orientation of the
robot’s end-effector based on known joint parameters.
2. In robotic programming, what does “tool center point (TCP)” refer to?
A. The sensor point used for collision detection
B. The reference point on the end-effector used for motion
calculations
C. The geometric center of the robot base
D. The communication endpoint with the controller
The TCP is the reference location on the tool that the controller uses
to plan and execute robot movements.
3. In an industrial robot, what is the function of an encoder?
A. To regulate motor temperature
B. To measure joint position or velocity feedback
C. To provide power to the servo drive
D. To filter communication signals
, Encoders provide feedback on joint position and velocity, which is
essential for accurate motion control.
4. What type of robot motion is typically used for welding applications?
A. Linear motion only
B. Circular motion only
C. Continuous path motion
D. Random point motion
Welding requires continuous, smooth motion along a programmed
path for consistent weld beads.
5. Which programming method allows an operator to guide a robot
through required positions manually?
A. Teach pendant programming
B. Offline simulation
C. Text-based coding
D. Automated calibration
Teach pendants allow manual guiding and recording of waypoints
directly on the robot.
6. What is the purpose of “axial runout” compensation in robot
programming?
A. To reduce communication latency
B. To adjust for tool alignment errors
C. To speed up motion profiles
D. To balance power distribution
Axial runout compensation corrects alignment discrepancies
between the tool axis and the actual TCP.
7. What is the standard safety feature to prevent robots from operating
outside a defined area?
A. Overcurrent protection
B. Emergency stop button
C. Safety fence or light curtain
D. Battery backup
Physical safety barriers like fences or light curtains prevent entry into
robot work envelopes during operation.
8. In industrial robots, what does “cycle time” refer to?
A. The time for tool calibration
, B. The time required to download a program
C. The time to complete one full programmed sequence
D. The time between maintenance checks
Cycle time is the duration it takes for the robot to complete its
assigned task loop.
9. What type of coordinate system is used to define robot motion
relative to the floor or base?
A. Tool coordinate system
B. World or base coordinate system
C. User coordinate system
D. Image coordinate system
The world system references the robot’s base and is used to position
movements relative to the floor or cell.
10. Why is path blending important in robot motion planning?
A. To increase programming complexity
B. To reduce power usage
C. To smooth transitions between motion segments
D. To isolate sensors
Path blending reduces stop-and-start motion, resulting in smoother,
faster, and more efficient paths.
11. What is the advantage of offline programming?
A. Requires robots to be powered down
B. Only usable for simple tasks
C. Allows simulation and programming without halting production
D. Reduces the need for encoders
Offline programming enables tasks to be developed and validated
without occupying the production robot.
12. In robot motion, what does the acronym “JPT” stand for?
A. Joint Positional Torque
B. Joint Position Target
C. Jump Path Transition
D. Jogging Path Technique
JPT indicates the target position for a robot joint as part of motion
planning.
