Multiple tasks employing swarms of autonomous robots have been investigated and implemented using swarm intelligence concepts. Modularity in complex systems results from breaking down the system into smaller, manageable components, facilitating easier understanding and parallel development processes. Additionally, modularity simplifies component replacement, maintenance, and the integration of new features. Therefore, swarm intelligence concepts combined with modularity have the potential to enable innovative and successful projects. This paper primarily focuses on integrating modularity concepts into swarm robotics platforms. A working model of the proposed platform, consisting of three individual robots, was developed to demonstrate the concept practically. This paper details the comprehensive design of the platform, including precise dimensions, hardware and software components, manufacturing processes, and costing analysis. Objectives included designing and fabricating a modular swarm robotic platform consisting of physical and algorithmic bases. Additionally, a Printed Circuit Board (PCB) was designed, and a CoppeliaSim-based 3D simulation platform was developed to observe swarm behavior and potentially incorporate swarm algorithms. Through these objectives, the paper aims to provide an affordable and adaptable swarm robotics platform, contributing to advancements in the field.
