Abstract

Home monitoring system has been one of the basic infrastructure that will be installed in almost every residential compound in this modern world while closed-circuit television has become the trend replacing the security guard to look after their house 24 hours. However, closed-circuit television system which uses non-mobile video camera and wired system have created some limitation to the system such as limited angle rotation of camera which lead to creating blinds spot and high usage of wire. Thus, in this project we will develop a remotely-controlled home monitoring mobile robot system with obstacle avoidance property which provide more flexibility and mobility to the existing home monitoring system. Nevertheless, a modern networking system of local area network system (LAN) will be applied to the home monitoring mobile robot that enable user to control the robot from long distance wirelessly. To obtain a more optimal motor speed control, Pulse Width Modulation technique (PWM) is being used due to the simple operation method. Different combination of motor PWM will create different mobile robot turning angle while different surface condition and different steepness of slope will required different motor PWM to overcome. Performance of the mobile robot is tested in task 2 and task 3 with different parameter. However, the first task of this project is to analyse the sensitivity of IR sensor for developing the obstacle avoidance system. In task 2, the most suitable turning angle for the mobile robot to avoid the obstacle will be tested through experimental test. Task 3 is carried out to test the performance of mobile robot encountering different steepness of slope in working environment. The result from all the task have been collected and collaborated with each other to produce the final prototype which have a precise IR sensor obstacle avoidance system and able to operate at different conditions
