After the initial section encompassing the analysis of the robotic arm market and the current technological landscape, the master's thesis provides a comprehensive description of the process involved in creating a custom robotic arm. The thesis covers the design development of the robotic arm, starting from conceptual development, modeling the design within a modeling software , all the way to the physical realization through 3D printing. Furthermore, a kinematic model of the robotic arm has been developed, which plays a pivotal role in solving the direct kinematic problem. This model enables precise control over the robotic arm's movements. Appropriate actuators for the robotic arm have been selected, including a stepper motor and servo motors, and an electrical system has been devised for their control. This system consists of an Arduino Uno R3 control unit, a stepper motor driver, sensors for object color and distance detection, LED lights for illuminating sorted objects for better color detection, and an LED light used for visual signaling of the robotic arm's status. Furthermore, a software code has been developed that allows the control of the robotic arm's movements based on information received from sensors through the Arduino programming environment, Arduino IDE.
