The design of this research to simulate the actual movements of the robot industry. This robotic arm designed with kinematics using forward kinematics and inverse kinematics by showing the movement of any DoF. This design includes the mechanical design model and available to control with microcontroller by using Arduino UNO. Each DoF are driven by DC motor which is controlled by using microcontroller. This application of robot arm is connected using a Graphical User Interface (GUI) Visual C# with calculation data covers kinematics. The result of this research obtained the lowest error percentage at special angle movements in the process of inverse kinematics at θ1, θ2 amounting to 0% of 0.011% and θ3 of 0.233%. While in the process forward kinematics retrieved the value of the error in x, y of 0%, and z of 0.39%.idTeknik ElektroMekatronikaTeknikRoboticsKinematicsThesis
