<br/><br/> The development of an unmanned vehicle for infographics and public announcement was an<br/>innovative approach designed to enhance information dissemination and campus-wide<br/>communication within the College of Industrial Technology. This study focused on designing and<br/>constructing a system capable of autonomous mobility, audio broadcasting, and infographic<br/>information to effectively deliver announcements in indoor facilities. The mechanical structure<br/>included a chassis and mounted wheels for mobility, and electronic parts such as the bluetooth<br/>speaker with wireless microphone for public announcement and digital tablet for infographic<br/>display, as well as internal mechanisms like a gear motor and battery. The system also included a<br/>variety of sensors, infrared and ultrasonic distance sensors for line reading and obstacle detection.<br/>The system underwent a series of tests, which indicated that it showed better accuracy tracking on<br/>smooth surfaces for curves and straight lines. These findings suggested that the prototype was a<br/>promising development in the field of public announcements. The prototype’s ability to deploy<br/>message ranges showed that clear announcements up to 500 cm distance, with a peak sound level<br/>of 84.5 dB and an average sound level of 80.9 dB, could lead to better distribution of information.<br/>Thirty respondents, consisting of students and faculty, evaluated the device based on its<br/>functionality, effectiveness, and design. The system received an overall rating of 4.84, indicating<br/>a high level of performance. Findings confirmed that the unmanned vehicle was a practical and<br/>reliable solution for improving public announcements in academic or public settings.
