Abstract

In today‟s era of well improved structure, demands in modern and new technology growth rapidly since it contributes a significant contribution in much kind of aspects. One of the most important and frequently used is the wireless communication system. In wireless communication system, Bluetooth has established itself as one of the vital communication system. In general, Bluetooth communication system lets users make effortless and fast connections between two devices or more. Due to low cost, low power consumption and short-range radio link, it is affordable for consumers to have it. Furthermore, there are many smartphones being produces which has the Bluetooth connectivity built-in the devices. The main objective of this project is to control the navigation of a mobile robot which is used as a prototype for an Automated Guided Vehicle (AGV) through Bluetooth communication system by using Android smartphone. This project will apply the wireless connection provided by Bluetooth and be able to control the AGV from smartphone. The structure for this project is divided into two main parts which is hardware and software. In hardware part, the Arduino microcontroller is used in order to enable the Bluetooth connection in 10 meters radius. In order to control the navigation of the mobile robot, an Android application is develop by using MIT App Inventor 2 software in software part. This project uses the hand gestures to move the mobile robot instead of pressing the keypad. The experimental result shows that when the human hand is moved towards certain gestures, then the robot tyre is moving towards the decided direction. All in all, the mobile robot is able to navigate following the instruction of the hand gestures.
