Robotics Interview Questions and Answers
Intermediate / 1 to 5 years experienced level questions & answers
Ques 1. Explain the difference between open-loop and closed-loop control in robotics.
Open-loop control relies on predetermined commands without feedback, while closed-loop control uses feedback from sensors to adjust the system and improve accuracy.
Ques 2. What is the importance of the PID controller in robotics?
A PID (Proportional-Integral-Derivative) controller is crucial for maintaining stability and precision in robotic systems. It adjusts control parameters based on error feedback.
Ques 3. Describe the concept of SLAM in robotics navigation.
Simultaneous Localization and Mapping (SLAM) is a technique that allows a robot to map its environment while simultaneously determining its own location within that environment.
Ques 4. What are the advantages and disadvantages of wheeled versus legged robots?
Wheeled robots are efficient on smooth surfaces but struggle with rough terrain. Legged robots offer better adaptability to diverse environments but may be mechanically complex.
Ques 5. Explain the term 'robotic middleware' and its role in robot control systems.
Robotic middleware is software that facilitates communication between different components of a robot system. It enhances interoperability and simplifies the development process.
Ques 6. What challenges are associated with human-robot collaboration in industrial settings?
Challenges include ensuring safety, defining clear roles for humans and robots, and developing intuitive interfaces for effective communication and collaboration.
Ques 7. What are the challenges in developing robotic systems for underwater exploration?
Challenges include high pressure, communication difficulties, and limited energy sources. Designing robust and efficient underwater robotic systems requires overcoming these obstacles.
Ques 8. Explain the concept of swarm intelligence and its application in robotics.
Swarm intelligence is inspired by the collective behavior of social organisms. In robotics, it involves multiple robots coordinating their actions to achieve a common goal, mimicking natural swarm behavior.
Ques 9. Discuss the role of computer vision in robotic perception and recognition.
Computer vision enables robots to interpret and understand visual information from the environment. It plays a crucial role in tasks such as object recognition, navigation, and manipulation.
Ques 10. Explain the concept of teleoperation in robotics.
Teleoperation involves controlling a robot from a distance. It is commonly used in situations where direct human presence is impractical or hazardous, such as in space exploration or hazardous environments.
