Design of Detectors on Automatic Trolley Using Ultrasonic Distance Sensors at Airports

摘要

Nowadays, problems with very high accuracy and speed and accuracy. Various equipment can operate or use with the help of mobile robotics. The automatic trolly design can run itself automatically by following the line follower or the line that we created to the check-in room. However, the automatic trolley cannot detect any obstructions in front of it or cover the line follower to endanger visitors who pass in the terminal room. From the problems above, this study uses ultrasonic sensors to detect obstacles or obstacles in front of the automatic trolly and use a buzzer to make a sound so that people know that the person has blocked or covered line follower of the automatic trolly.
