CHAPTER I
INTRODUCTION
This chapter will briefly discuss on the project overview. The objective, scope, and thesis outline will be presented in this chapter.
1.1 Project Background
Color Sorting System with Robot Arm is based on the placing system with some capability to decide the object according to their color. The object will be defined by
determining color of the object while the system will figure which location the object should be located. This system use Programmable
Interface Controller PIC to control the whole system.
There are four main parts in this system: robot arm
ball tower color sensor
ball collection station
Firstly, a manually feed object will be determined by the robot. The gripper of the robot will pick up the object and place it to a color differentiating station. The color
2
differentiating station consists of a Light Dependent Resistor LDR which will detect the light reflected by the object. By comparing the reflected light value with the calibrated
value stored in the PIC data base, the PIC controller will process the data and determine the color of the object.
After determining the color of the object, the gripper of the system will pick up the ball and move it to the desire color station. There are four three color station in this
system, there are red station, green station, and blue station. Depending on the color of the object, the gripper will move the object to the correct destination and place the object
inside that station.
Figure 1.1: The Overview of the Color Sorting System The operation of whole system is as below:
1. The ball tower detects the existence of the ball.
2. The robot arm move it gripper to that ball and pickup the ball.
3. The robot arm sends the ball to the color sensor station.
4. The color sensor station will determine the color of the ball.
5. The robot arm will move the ball to appropriate ball collection station based
on the result produce by color sensor station. 6.
The robot arm returns to its original place, and repeat the whole process if there is another ball in the ball-tower station.
