Design and Development of an Obstacle Avoidance Mobile-controlled Robot

Mobile robot development has been receiving attentions from researchers worldwide in recent years, especially in developing autonomous mobile robots. However, there are still needs for developing semi-auto robots, mainly for allowing human-assisted control mechanism while operating the robots. This is greatly helpful in performing site surveying tasks and where environment setup is variable or unknown. In this research, an obstacle avoidance mobile-controlled robot is developed using an Arduino Uno R3 microprocessor operated by controlling of a mobile Android-based device via Bluetooth. Apart from performing well basic functions like moving forward and backward, turning left and right, the robot is able to detect preceding obstacle, stop movement, and then identify suitable clear way for avoiding the obstacle.
