The correct answer is: D. All of the above
An automation system is a system that uses various components to control and monitor a process or system without human intervention. Automated warehouses, numerically controlled machine tools, and robotics are all examples of automation systems.
Automated warehouses are warehouses that use automated systems to store and retrieve goods. These systems can include conveyor belts, robots, and other automated equipment. Automated warehouses are often used in large-scale distribution centers, where they can help to improve efficiency and accuracy.
Numerically controlled machine tools are machine tools that are controlled by a computer. These machines can be used to create complex parts with high precision. Numerically controlled machine tools are often used in manufacturing, where they can help to improve quality and productivity.
Robotics is the field of engineering that deals with the design, construction, operation, and application of robots. Robots are machines that can be programmed to perform a variety of tasks. They are often used in manufacturing, where they can help to improve efficiency and safety.
All of these systems use automation to control and monitor a process or system without human intervention. Therefore, they can all be classified as automation systems.
