Abstract: The present invention relates to the field of industrial robotics and intelligent manufacturing, and more particularly to a smart multifunctional 3D-printed robotic manipulator capable of performing pick-and-place operations, spray painting, and Metal Inert Gas (MIG) welding using interchangeable end-effectors. The robotic manipulator comprises a lightweight five-degree-of-freedom (5- DOF) articulated arm fabricated through additive manufacturing using Acrylonitrile Butadiene Styrene (ABS) material, thereby reducing manufacturing cost, overall weight, and fabrication time while maintaining adequate structural strength. The manipulator is integrated with an ESP32-based intelligent control unit that provides real-time motion control and wireless connectivity through Wi- Fi, enabling remote operation using a mobile application and web-based interface. The system incorporates precision servo actuators, an interchangeable quick-mount end-effector assembly, and programmable motion control algorithms to perform multiple industrial tasks without requiring separate robotic platforms. The end-effector can be configured as a gripper for material handling, a spray painting nozzle for uniform surface coating, or a MIG welding torch for automated welding applications. The modular design enables rapid tool replacement, thereby improving operational flexibility and reducing production downtime. The proposed invention offers an economical, compact, and scalable robotic automation solution suitable for small- and medium-scale industries, educational institutions, research laboratories, and smart manufacturing environments. By integrating additive manufacturing, IoT-enabled wireless control, modular end-effector interchangeability, and programmable multifunctional operation into a single robotic platform, the invention significantly improves productivity, reduces human intervention in hazardous environments, minimizes equipment cost, and enhances process efficiency across multiple industrial applications. Keywords: Smart robotic manipulator, 3D printing, ESP32, IoT, multifunctional robot, pick-and-place, spray painting, MIG welding, interchangeable end-effector, industrial automation.
