DEVELOPMENT OF BEVERAGES DISPENSING COBOTIC SYSTEM USING RASPBERRY PI AND ARDUINO UNO

Abstract

The integration of modern technology has significantly transformed various industries by automating daily tasks and enhancing operational efficiency. Artificial Intelligence has enabled the development of collaborative robots (cobots) capable of performing repetitive functions with minimal human intervention. This study aims to develop a Beverages Dispensing Cobotic System using Raspberry Pi and Arduino Uno to address existing challenges in AI-driven systems, such as limited customer interaction, safety concerns, dependency on human supervision, and restricted payload and speed capacities. The prototype incorporates real-time database management, Internet of Things (IoT) integration, safety mechanisms, interactive displays, and audio systems to enhance automation while maintaining options for manual control. The system is intended to support the hospitality sector, improving service delivery for employees and customers alike. This study employs the Experimental Prototype Development Method to design and evaluate the proposed cobotic beverage dispensing system. The development process includes identifying material requirements, assembling an initial prototype, evaluating system performance, and applying enhancements based on feedback. Prototyping plays a vital role in refining usability and functionality while gauging customer satisfaction. The methodology allows for iterative improvements and ensures that system performance aligns with design specifications prior to final production. Prototype testing focused on ensuring that individual components met functional requirements and overall usability standards. The cobotic system’s database was designed to classify beverage identifiers, names, timestamps, and quantities served. Operational tests verified the performance of critical components including cobotic arms, mobility wheels, and water pumps. The system demonstrated successful interactive service capabilities. Respondents, primarily workers and personnel from the hospitality sector, expressed a high level of satisfaction, with an overall weighted mean of 3.43 for system functionality, and a score of 3.11 for both reliability and portability based on a four-point Likert scale. These results indicate a generally favorable reception and usability of the system. The findings suggest that Raspberry Pi and Arduino Uno are effective microcontroller units (MCUs) for developing a functional cobotic beverage dispensing system. The proposed prototype meets the requirements of hospitality and bar establishments, offering a portable, reliable, and sustainable solution that complies with engineering standards. Its positive reception among users demonstrates potential for real-world application, contributing to enhanced customer service, operational efficiency, and technological advancement in the service industry.
