I. Introduction
This paper describes a Robotic Arm for sorting products according to their respective colors. The electronic control system of the robot utilises the System-on-Chip technology to design a low cost, low turnaround-time color sensing solution for an academic robot. Robots are used in industry for applications such as welding, painting, assembly, packaging, palletizing and SMT, product inspection, and testing; all of which can be accomplished with high endurance, speed and precision. Advances in camera technology have dramatically reduced the cost of cameras, making them the sensor of choice for robotics and automation. Vision provides a variety of cues about the environment (motion, color, shape, etc.) with a single sensor [1]. In this paper the color aspect of vision is discussed. System-on-Chip (SoC) technology is becoming a widely accepted architecture for complex and heterogeneous systems that include digital, analogue, mixed-signal, radio-frequency, micromechanical, and other types of components on a single piece of silicon [2].
