Basic Concepts of Industrial Robot Parts
An industrial robot is a programmable electromechanical device designed to perform repetitive or hazardous tasks with precision and efficiency. Its versatile design consists of several interconnected components that work together seamlessly. These components can be broadly classified into three main categories:
-
Mechanical Structure - The physical framework of the robot, including joints, links, actuators, and end-effector.
-
Control System - The brain of the robot, comprising controller, sensors, and software.
-
Power Supply - Provides the necessary energy to operate the robot, typically through electric motors or hydraulic/pneumatic systems.
