Ques 1. What is the basic difference between a robot and an automation system?
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.
Ques 2. Explain the concept of kinematics in robotics.
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.
Ques 3. What is the role of sensors in robotics?
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.
Ques 4. Define the term 'degrees of freedom' in the context of robotic manipulators.
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.
Ques 5. What is the significance of the 'end effector' in a robotic system?
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.
Intermediate / 1 to 5 years experienced level questions & answers
Ques 6. 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.
