/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
    /* Create an autonomous robot that integrates */
    /* ultrasonic object detection and infrared line- */
    /* following capabilities to navigate complex */
    /* environments while avoiding obstacles effectively. */
/****** END SYSTEM REQUIREMENTS *****/

/****** DEFINITION OF LIBRARIES *****/
#include <NewPing.h>  // Library for ultrasonic sensor
#include <IRremote.h> // Library for infrared communication

/****** FUNCTION PROTOTYPES *****/
