Automated Service Robot for Catering Businesses Using Arduino Mega 2560

As technology becomes more advanced, the use of robots will further increase in the near future. It is expected that most of these robots are industrial robots and are most likely to be utilized in the upcoming years. However, the use of other types of robots, such as service robots, is also expected to increase gradually in the future. A waiter robot is a type of service robot that works in a catering business by performing the roles of a waiter, such as serving meals or accepting orders depending on its function. Currently, waiter robots are facing limitations. The main factor is how it navigates and interacts within a human environment. This paper aims to create a service robot that serves orders in a catering business. Arduino Mega 2560 was used as a microcontroller, and the line-following algorithm was used to guide the robot to the location of the dining tables. Two ultrasonic sensors were used to detect obstacles from a distance. Results show that the robot moves at a speed of 0.06 m/s in controlled testing and maintains that constant speed while carrying a maximum of 15kg load. Furthermore, it is shown that the robot is capable of serving multiple orders at a single dining table. The robot was able to serve 56 customers in a restaurant.
