Interview Questions and Answers

Open-loop control relies on predetermined commands without feedback, while closed-loop control uses feedback from sensors to adjust the system and improve accuracy.

A PID (Proportional-Integral-Derivative) controller is crucial for maintaining stability and precision in robotic systems. It adjusts control parameters based on error feedback.

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.

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.

Robotic middleware is software that facilitates communication between different components of a robot system. It enhances interoperability and simplifies the development process.

Challenges include ensuring safety, defining clear roles for humans and robots, and developing intuitive interfaces for effective communication and collaboration.

Challenges include high pressure, communication difficulties, and limited energy sources. Designing robust and efficient underwater robotic systems requires overcoming these obstacles.

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.

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.

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.
