Abstract

This article presented a study on the efficiency of image processing techniques for controlling a small robotic arm. The system used a webcam to capture images, which were then processed using the PyCharm program. Micro servo motors served as the driving mechanism for the robotic arm, controlled through an Arduino board. The robotic arm operated based on hand movements, utilizing real-time hand detection techniques that measured the distance between the hand and the camera. The image processing analyzed the movement patterns and distance of the hand to determine whether it was moving forward, backward, left, right, grasping, or releasing an object. This information was then used to command the microcontroller, which controlled the small robotic arm's movement along the X, Y, and Z axes. Test results showed that the image processing techniques effectively controlled the small robotic arm's movement along the axes. The X, Y, and Z axis values changed according to hand movements. When testing the robotic arm's ability to move an object from left to right at a distance of 35 centimeters, the average time for object movement was 34.51 seconds. When powered by a 12-volt, 2200 milliamp-hour lithium-polymer battery, the small robotic arm could operate for an average of 20 hours and 45 minutes.
