Abstract: Robotic arms are extensively used in industrial automation to perform repetitive and accurate operations such as picking, placing, and assembling components. However, traditional robotic systems are generally expensive, complex to operate, and require specialized infrastructure. This project focuses on the design and development of a low-cost robotic arm fabricated using 3D printing technology and controlled through a mobile device. The system utilizes an ESP32 microcontroller as the central controller, which communicates with a mobile application through Bluetooth or Wi-Fi to control the movements of the robotic arm.
