What is defined as an automatically controlled reprogrammable multipurpose manipulator programmable in three or more axes?

An industrial robot is defined as an automatically controlled, reprogrammable multipurpose manipulator that is capable of being programmed in three or more axes. This definition encapsulates the critical characteristics of industrial robots, which include their ability to perform a variety of tasks in manufacturing and production environments. They are designed to operate with high precision and can be programmed to carry out repetitive tasks, making them essential for processes like welding, assembly, painting, and materials handling. Their multipurpose nature allows them to be used across different industries, adapting to various tasks by simply changing their programming without the need for significant mechanical alterations. The capability of operating in three or more axes indicates their operational flexibility and effectiveness in executing complex movements and tasks.

In contrast, automated systems might refer more broadly to systems that automate processes and do not necessarily include the specific multi-axis programming capability. A mechanical arm, while similar, typically lacks the advanced programming features and versatility of an industrial robot. A programmable logic controller is a type of digital computer used for automation of industrial electromechanical processes and does not fit the description of a manipulator. These distinctions clarify why the term industrial robot accurately fits the provided definition.
