A robotic arm is a highly sophisticated, electromechanical device designed to emulate and surpass the dexterity, precision, and strength of a human limb in a controlled industrial or research environment. This advanced machinery embodies the fusion of cutting-edge engineering, robotics, and artificial intelligence, enabling it to execute an array of intricate tasks with remarkable efficiency and accuracy.
The structural composition of a typical robotic arm mirrors that of a human arm, featuring several interconnected segments: a base mount serving as the "shoulder," an elbow joint allowing for flexion and extension, a wrist with rotational and pivotal capabilities, and a terminal effector, often resembling a "hand" tailored to specific applications such as gripping, welding, or painting. These components are linked by robust, precisely engineered joints, typically driven by servo motors, which provide precise control over position, velocity, and torque.

A 3D printer is an innovative technology that fabricates three-dimensional solid objects from digital models, layer by layer, using various materials such as plastics and metals.
