1. In robotics, the term “degrees of freedom” refers to:
A. The number of power sources a robot has
B. The number of axes or independent motions the robot can perform
C. The maximum payload capacity
D. The speed range of the robot
Correct answer: B. Degrees of freedom indicate the number of
independent motions a robotic system can execute, defining its
ability to move in different directions.
2. Which sensor type is commonly used for obstacle detection in mobile
robots?
A. Barometer
B. LIDAR
C. Thermistor
D. Hygrometer
Correct answer: B. LIDAR is widely used for mapping and obstacle
detection due to its precise distance measurement capability.
3. In control systems, a PID controller’s “I” component is responsible for:
A. Proportional error correction
B. Predicting future error
C. Eliminating steady-state error
D. Adding noise to the system
, Correct answer: C. The integral term in a PID controller helps
eliminate residual steady-state error.
4. A robot manipulator typically uses what type of joint for rotational
motion?
A. Prismatic
B. Revolute
C. Linear
D. Translational
Correct answer: B. Revolute joints allow rotational movement
around an axis.
5. The primary purpose of a robot’s end effector is to:
A. Provide power to the robot
B. Navigate the robot
C. Interact with the environment
D. Supply data to the controller
Correct answer: C. End effectors are designed to perform tasks such
as gripping or tooling.
6. SLAM in robotics stands for:
A. Simultaneous Location And Mapping
B. Sensor Localization and Motion
C. Simultaneous Localization And Mapping
D. System Linear Actuator Measurement
Correct answer: C. SLAM is a technique for building a map while
tracking a robot’s location within it.
7. The primary advantage of brushless DC motors in robotics is:
A. Higher noise level
B. Higher efficiency and longer life
C. Lower cost
D. More friction
Correct answer: B. Brushless DC motors offer higher efficiency and
reduced maintenance.
8. In ROS (Robot Operating System), a “node” is:
A. A hardware module
B. A database entry
C. A power supply
, D. A process that performs computation
Correct answer: D. Nodes are executable processes in ROS that
communicate with each other.
9. Which communication protocol is commonly used for real-time motor
control?
A. HTTP
B. CAN bus
C. SMTP
D. FTP
Correct answer: B. CAN bus is often used in embedded systems for
reliable real-time communication.
10. The Denavit-Hartenberg parameters are used to:
A. Calibrate sensors
B. Describe kinematic chains of robots
C. Control battery power
D. Manage network protocols
Correct answer: B. D-H parameters standardize the representation of
robot joint geometry.
11. A robot’s workspace envelope refers to:
A. The robot’s outer casing
B. The volume of space the robot can reach
C. The robot’s manufacturing tolerance
D. The robot’s payload rating
Correct answer: B. Workspace envelope describes the spatial region
reachable by the robot’s end effector.
12. In image processing for robotics, edge detection is primarily
used to:
A. Reduce color saturation
B. Identify object boundaries
C. Increase brightness
D. Measure temperature
Correct answer: B. Edge detection algorithms highlight significant
intensity changes to delineate object edges.
13. A stepper motor is best known for:
A. High torque at high speed
