  1. What are the main components of a robotic system?

    • Explanation: This question assesses your understanding of the fundamental building blocks of a robot, including sensors, actuators, controllers, and software systems. It evaluates your knowledge of how these components interact to perform tasks.
  2. Can you explain the concept of kinematics in robotics?

    • Explanation: Kinematics is the study of motion without considering forces. This question checks your understanding of how robots move, including concepts like forward and inverse kinematics, which are crucial for robot motion planning and control.
  3. What is the difference between a robot manipulator's degrees of freedom (DOF) and its workspace?

    • Explanation: This question tests your knowledge of the robot's physical capabilities. Degrees of freedom refer to the number of independent movements a robot can make, while workspace defines the spatial area within which the robot can operate.
  4. How do you differentiate between open-loop and closed-loop control systems?

    • Explanation: This question assesses your understanding of control systems. Open-loop systems operate without feedback, whereas closed-loop systems use feedback to adjust their actions and improve accuracy and stability.
  5. What are the different types of sensors used in robotics, and what are their applications?

    • Explanation: Sensors are critical for robots to perceive their environment. This question evaluates your knowledge of various sensors like LIDAR, cameras, ultrasonic sensors, and their applications in navigation, object detection, and environmental mapping.
  6. Explain the concept of path planning in robotics.

    • Explanation: Path planning involves determining a feasible route from a starting point to a destination. This question tests your understanding of algorithms and techniques used in robotics to ensure safe and efficient movement, including A* and Dijkstra's algorithm.
  7. What is SLAM (Simultaneous Localization and Mapping), and why is it important in robotics?

    • Explanation: SLAM is a method used by robots to build a map of an unknown environment while simultaneously keeping track of their location within it. This question assesses your understanding of one of the most challenging and critical problems in autonomous robotics.
  8. How do robots achieve obstacle avoidance?

    • Explanation: This question evaluates your knowledge of the techniques and algorithms used to detect and avoid obstacles, ensuring the robot can navigate safely in its environment. Techniques might include sensor fusion, potential fields, and reactive control strategies.
  9. What are the main challenges in human-robot interaction (HRI)?

    • Explanation: HRI is a critical area in robotics focusing on how humans and robots communicate and work together. This question tests your understanding of challenges such as safety, communication protocols, and creating intuitive interfaces for collaboration.
  10. Can you discuss the ethical considerations in robotics?

    • Explanation: This question assesses your awareness of the broader implications of deploying robots in various sectors. Ethical considerations might include job displacement, privacy concerns, decision-making autonomy, and ensuring that robots are used responsibly.
