DESIGN AND DEVELOPMENT OF IOT BASED ROBOT FOR COMMERCIAL APPLICATIONS

Abstract

The rapid advancement of technology, particularly in the fields of robotics and the Internet of Things (IoT), has significantly
transformed various industries, including the hospitality sector. Automation in restaurants has become a focal point of innovation, leading to increased efficiency, reduced operational costs, and enhanced customer satisfaction. Traditional restaurant service relies heavily on human waitstaff, which introduces several challenges such as high labor costs, order inaccuracies, long wait times, and inconsistent service quality. With growing concerns regarding hygiene and social distancing, particularly in the post- pandemic era, automated food delivery systems have gained considerable attention as a viable alternative.
The development of an IoT-based waiter robot aims to streamline restaurant operations by automating the food delivery process. This paper presents the design and implementation of an autonomous food-serving robot that integrates IoT for remote monitoring and control. The system uses an Arduino Nano microcontroller, RF communication, ultrasonic sensors, voltage sensors, an LCD display, a motor driver, and wheels to enable smooth and efficient navigation within a restaurant environment. The robot follows a line- following mechanism for path navigation while employing ultrasonic sensors for obstacle detection and avoidance. The integration of IoT technology allows restaurant staff to remotely control and monitor the robot’s movement, status, and battery levels through a web or mobile application.
