This paper revolves around a mobile robot that can sense its distance from a certain obstacle. This project makes use of the PIC16F877A microcontroller for it to function. The read length measurement is programmed to exhibit continuously onto a liquid crystal display (LCD). The movement of the robot’s motor is controlled by the use of a L293D integrated circuit. The mobile robot (MOBOT) embedded system’s overall purpose is similar and could be compared to a bat’s echolocation skills.
