A Smart Dining Assistance Robot Enabled by IoT Connectivity and Android-Based Interaction Framework

Abstract

This work introduces the development of an automated service system termed a Smart Dining Robot, designed to improve operational efficiency and customer experience in modern restaurant environments. The system is built around an Arduino microcontroller platform (Arduino – Open-Source Microcontroller Board) that coordinates multiple hardware and software components for seamless food delivery operations. An intuitive touchscreen interface enables users to place orders, access real-time updates, and manage system interactions with ease. For navigation and obstacle avoidance, the robot integrates Infrared Sensors (IR – Infrared) along with Bluetooth Communication (Bluetooth – Wireless Short-Range Communication Technology), ensuring precise movement and reliable table-to-table delivery. In addition, the system incorporates an Internet of Things (IoT – Internet of Things) based temperature monitoring mechanism, where environmental and food conditions are continuously tracked and displayed through a Graphical Liquid Crystal Display (GLCD – Graphical Liquid Crystal Display). Supporting components such as a Regulated Power Supply (RPS – Regulated Power Supply), keypad modules, and control switches enhance system stability and user interaction. The overall design emphasizes automation to reduce manual intervention, minimize service delays, and increase service accuracy. Furthermore, the architecture is scalable and cost-effective, allowing easy adaptation to different hospitality settings. By integrating embedded systems, wireless communication, and intelligent monitoring, the proposed solution demonstrates a practical step toward smart restaurant automation and provides a flexible platform for future advancements in service robotics.
