'Go green' smart robot: article

The main objective of this project is to design and develop a robot to pick up a dustbin that is filled with rubbish, and will go to the main dustbin to transfer all rubbish. After that, the robot is place back the dustbin at the original position and the robot will be back to the original position. The movements are using line follower system that involved many part of sensor while the movement of robot is drive by two DC motors. The development of the robot involved several mechanical systems . One of the mechanical systems is based on forklift system that is used to pick up dustbin. The forklift system is one of the main mechanical systems in the robot. The system is selected as it is easy to implement, easy to control or programming and less of component in order to build the system. The forklift system in this robot is drive by 12V DC motor. There are three targets to achieve in order to build this robot. Firstly the component and system will be simple as can but still able to fulfill the task. Secondly is to get the best design hardware and lastly the robot will operate and do the task with smoothly and less of error. A 300 MHz Radio frequency Module is used as wireless link which is able to transfer signal between transmitter circuit and receiver circuit. The transmitter circuit is place at the dustbin system while the receiver circuit is place at the robot system. PIC16F877A is a microcontroller to control the entire component in the robot system. The robot is start to operate once the signal is send by the dustbin to the robot via transmitter
