This article focuses on the hardware development of an educational robotic arm that spans across multiple fields of mechanical and electrical engineering, from the initial idea, design and 3D printing, to assembly of system components. Almost all parts are designed in 3D CAD software, printed on a 3D printer, and assembled from readily available, inexpensive electrical components to achieve an economically accessible final product with ease of assembly. Control can be achieved using any platform that contains a minimum of 10 general-purpose input/output pins at 3.3V, such as Raspberry Pi mini-computers, ESP32, or ESP8266 development platforms. By utilizing additional IoT capabilities of these development platforms, the control capabilities of the educational robotic arm expand to the internet. This work focuses on mechanical performance, design, 3D printing, and assembly of components into a single platform compatible with most DIY control and programming platforms. Depending on the platform, various sensors and actuators can be added with different communication methods with other devices according to user preferences and project requirements.
