Development of 3-DOF robotic arm sorter based on color type using a microcontroller

Today, one of the sorting systems developing in the industrial economy era is robotic arms. The sophisticated technology in the arm sorting system can replace human tasks and continuously operate without feeling tired. Therefore, this study designed a 3-DOF robotic arm prototype and made it to sort objects by colour type. The robot arm has been successfully designed and realized with 3 degrees of freedom with an average success rate of sorting objects according to a predetermined colour with reasonably good results from the research that has been done. Based on the results, the failure analysis was due to the shape of the test object being larger than the clamp designed for the robot arm.
