Abstract
Creating a Navigation algorithm for autonomous cars in closed quarters, using ultrasonic waves transmitted from speakers in a foretold location. we receive and process the data in order to locate the robot and thus be able to navigate it. We use mathematical tools including triangulation method.
Mapping Process
In the Mapping process, we are calculating the location using the time difference of signal reception from three speakers, so theoretically we need the three signal transmission to be simultaneous. we will make this happen by subtracting the transmission time difference from the reception time difference.
Final Application
Shows location of x,y coordinates and graph of detected frequencies
