Design of touch screen based robot with obstacle detection module for autonomous path navigation

摘要

Autonomous path navigation is the best known method for indoor navigation. This paper proposes a novel design of an autonomous path navigation robot based on the touch screen. The robot has the capability to move from specific location to any other chosen location that can be customized with a fixed path. The current position of the robot is displayed on the touch screen. Once user touches specific part of the screen, the device motors would get activated and it will start to move towards its destination based on the fixed route map in the program. In case of unknown environments user can move in any direction by touching the direction keys or turning keys of the touch screen. The ultrasonic sensors will provide information regarding path clearance to the robot. If any obstacle in its path, the robot can adjust itself till it locates obstacle clear path. The calculated results depict the robustness of the touch-screen based robot with obstacle detection module. Based on these results, it is ensured that the proposed method can be used for different applications where the autonomous path navigation is needed.
