Arduino-Controlled BLDC Motor for the Mobility of Asia Pacific College RamiBot: Concierge Robot

This paper is about Asia Pacific College's (APC) innovative concierge robot, RamiBot. One critical aspect of RamiBot's effectiveness is its seamless navigation and mobility within the college lobby. The focus of this paper is enhancing RamiBot's mobility through the integration of BLDC motors and Arduino control. The importance of certain technological elements for enhancing the mobility of an efficient concierge robot was discussed in the background. The objective of this project is to use an Arduino microcontroller to control a BLDC hub motor, testing its responsiveness and RPM both loaded and unloaded. Meanwhile, the scope includes testing the motor-Arduino responsiveness and maximum RPM of RamiBot and evaluating its accuracy in reaching designated targets. This also outlines the default and opposite motor orientations, which are required for forward and reverse movement. Moreover, it illustrates how system commands are translated into motor actions, allowing for a better understanding of the process. It also depicts the sequence of actions RamiBot takes in response to system inputs, allowing it to move forward, backward, rotate left, rotate right, or stop/brake. Furthermore, speed computation takes into consideration the maximum RPM and average walking speed, providing a basis for determining the appropriate RPM for RamiBot's operation. Lastly, the conclusion emphasizes the system's positive features, such as smooth operation and quick responses, while addressing concerns about stability and user experience. RPM testing confirms the motor's ability to maintain the indicated speed and discusses recommended speed safety considerations. Overall, this paper provides in-depth research into improving RamiBot's mobility. It provides important insights into the technical aspects and considerations involved in developing an agile robotic mobility system, ensuring RamiBot's effectiveness in assisting visitors, students, and faculty members in the college lobby.
