This paper presents the development of a dynamic ball-and-plate system successfully completed for a one-semester Senior Capstone Design project. A group of five undergraduate students developed the project concept and constructed a prototype within a semester, integrating major mechatronics engineering concepts learned in classes. The three-degree-of-freedom system consists of sensors, actuators, and controls to keep a free rolling ball in a desired position on a flat plate, accounting for any possible external disturbances. Due to its complexity, multiple steps were taken to solve the design challenges and develop the system. The major works were mathematical modeling, kinematic constraints and dimensional analysis, simulations, and construction of the system. The control system required an effective control strategy and a thorough analysis of system parameters. The system's feasibility and optimal operation were fully considered in the design phase. The design was then validated by simulations using Simulink/MATLAB™ and experimental testing. The completion of the system development provided the understanding of analyzing different control designs on various system parameters based on multidisciplinary mechatronics design principles. Lastly, the class outcomes confirmed the effectiveness of students' learning on multidisciplinary mechatronics engineering through this hands-on project as an assessment of the design project presented.
