1.2 OBJECTIVE

This project is developed with the purposed to optimizing the productivity, minimizing the cost of the project and make no human mistakes. The main thing of this project is to study how to use the programming language to communicate with the PIC controller. After determining the color of the object, the robot arm system will make its own decision to the station that been programmed. The objective can be summarized as below: i. To sort the object according to their color. ii. To sort the object to the station accordingly. iii. To make the system run continuously with less rest. iv. To make an interface between the programming of robot arm and the sensors. v. To make the robot’s gripper has the function of pick and place. vi. To make the robot capable to stop at the desire location accurately.

1.3 SCOPE OF PROJECT

This project is subjected to several scope and limitations that are narrowed down to the study. There are a few scopes and guidelines listed to ensure the project is conducted within its intended boundary. This is to ensure the project is heading in the right direction to achieve its intended objectives. The objectives are: i. Research and study on the Programmable Intelligence Computer, PIC16F876A microcontroller and the control system of the circuit. ii. Research and study on C programming language to communicate with the microcontroller. iii. Research and study on the Light Dependent Resistor for color sensor. iv. Research and study on the Infra Red transmitter and receiver for proximity sensor. v. To design circuitry for the overall system. 4 vi. To fabricate a PCB circuit board for the overall system. vii. To develop the program that can integrate and control the overall system. viii. To construct the model and test either the robot is function or not.

1.4 PROBLEM STATEMENT

The problems which often occurred in the industrial that can be solved by this project are: i. The speed of color sorting process by an operator is very slow. This is due to the limitation of response time for a human eye. The eye will always take some time to see an image and project this to the brain to initiate visual sensation. After the brain has received the image, it will take some time for the brain to determine the color of the object too. However, this limitation can be covered by using a computer. In this project, a PIC microcontroller is used to increase the speed of color sorting . ii. The accuracy of color sorting process by an operator is very slow. This is because an operator will need to handle hundred or thousand of object each day, they will feel boring and their eyes are tired after a long day working. It was a very common case for an operator to give wrong result. However, a machine will not have this problem. A machine will give accurate result even after it has repeated a process for billions of times. In this project, a PIC microcontroller was used to substitute the operator and thus increase the accuracy of color sorting iii. The implementation cost for a color sorting process using the operator is very high. This is because the work load for an operator is very low. If an industry needs to sort a bulk quantity of product, they have to recruit many workers, implement shift and overtime system for the workers. This will definitely increase the cost of a product. In this project, a color sorting system was designed so that to increase the process time, increase the process accuracy, 5 and cut-down the cost of process of color sorting. This project should overall optimize the productivity of an industrial
