Tóm tắt

As the era of industrial 4.0 coming, robots replace most of the human work is no stranger to us. However, in Vietnam, putting robots in service industry such as waiter robot serving in restaurants is still very limited. This study presents the development of restaurant serving robot using line following approach. The robot is designed by referring to the survey on the size and appearance requirement at a restaurant. Robot is programmed to come to a specific table by mapping data. Based on the line reading algorithm implemented on microcontroller PIC18F4550, the robot follows the line marked on the floor to move to the desired table position and returns to the service counter after completing the task. There are ultrasonic sensors on the robot that can detect the obstacle to help the robot stop and output warning signal. The robot also can output some simple voice to customers in English, Korean and Vietnamese such as \"welcome\", “please enjoy your food\"...
