Interview Questions and Answers

A robot is a programmable machine capable of performing tasks autonomously, while an automation system involves the use of control systems to operate equipment without human intervention.

Kinematics is the study of motion in robots without considering the forces causing the motion. It involves position, velocity, and acceleration analysis of robot mechanisms.

Sensors in robotics are used to gather information about the robot's environment. They provide feedback for control systems, enabling the robot to adapt to its surroundings.

Degrees of freedom refer to the number of independent parameters or motions that define the configuration of a robotic manipulator. It represents the flexibility of movement.

The end effector is the device or tool at the end of a robotic arm designed to perform specific tasks. It is crucial for the robot to interact with its environment.

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.
