Controlling and Tracking of Mobile Robot in Real-Time Using Android Platform

摘要

The advanced technology as well as capacity of computer growth has offered dynamic opportunity in the advancement of robotic controls and realization of novel techniques of control system. This technological advancement collectively with the need for good performance robots created accurate and faster. This research presented the controlling and tracking of the mobile robot using Video Broadcasting Feature (VBF) and Audio Broadcasting Feature (ABF) for the unknown environment applications. It is a android based autonomous robot with bluetooth and Wi-Fi are used for communication between robot and remote controller. The robot is to be able to move in all four directions which are forward, backward, left and right movements via remote control. This robot is self powered with 9 V supply to power up the microcontroller, motors and transmitter for audio broadcast. Besides that android smart phone is used for video broadcasting with its own battery. The microcontroller used to control the robot remotely is the Arduino, it has built-in input and output ports and other functions. For the real time audio transmitter, it will detect voice and any kind of audio using a mini electric microphone to transmit the signal when detected through a transmitter circuit that is designed to transmit the sound with the specified frequency range. This robot has real-time video broadcasting capability to watch the activities that take place in other places. The real-time video coverage is broadcast by using smart phone that uses broadcasting software called twitcasting. The video is transmitted using internet medium for longer range receiving destination. This mobile robot can be useful in surveillance purpose or military purpose for spying.
