I just have finished doing a simulation by Matlab environment for navigation a mobile robot from its initial point to goal point without collide with any obstacles dependent on the Artificial Potential Field algorithm , and it is done successfully.
Now , I would like to do that practically and I'm new to this "world" , I have built my robot with two motors and ultrasonic sensors , but the hardest part which I faced is which components should I have to get the current position (i.e. (x,y)) and the orientation (i.e. Azimuth) of mobile robot , so what is the simple approach and simple components for this task , please give me the simple solution because I am novice and I have no enough time, it is just one month and I should finish that . I would be very much appreciate any help.
