<![CDATA[The development of service robots has gained increasing attention as a solution to improve efficiency and consistency in food delivery services, particularly in environments with limited space and dynamic conditions. This study aims to design and implement an Arduino-based food delivery robot with Bluetooth control operated via a smartphone. The research employs a prototype-based development method, encompassing system requirement analysis, mechanical and electronic design, prototype construction, and functional testing. The robot is equipped with an Arduino Uno R3 microcontroller, DC gearbox motors, a Bluetooth HC-06 module for wireless communication, and an audio system to support basic human–robot interaction. System testing focuses on evaluating the robot’s ability to respond to movement commands and audio activation instructions transmitted through a smartphone application. The results demonstrate that the developed prototype is capable of executing directional movement commands and activating the audio system consistently within the defined operational range. These findings indicate that low-cost embedded platforms can be effectively utilized to develop functional food delivery robot prototypes suitable for controlled environments such as parties or small-scale service settings. This study contributes to the validation of a simple and replicable service robot design that may serve as a foundation for further development toward more autonomous and intelligent robotic service systems.]]>
