A Graphical User Interface for Path Planning of Mobile Robot

Abstract

This paper presents a graphical user interface (GUI) for path planning of mobile robot using a modified bat algorithm in a 2D environment containing rectangular static obstacles. The modified bat algorithm was used as the controller that guided the mobile robot based on the echolocation behaviour of bats. This enables the mobile robot to move from a source position to a target destination without colliding with the obstacles. A GUI based path planning simulation environment was developed to display the optimal collision free path generated by the controller. With the GUI software, it is easier for a user to implement path planning of mobile robot as user has opportunity to define environment variables without having knowledge of programming. The simulation result obtained shows that the modified bat algorithm path planning controller generates a collision free optimal path with minimum elapsed time. This indicates that the software is a good technique for implementation of mobile robot path planning in different scenarios of obstacles and maps size
