Analyzing Modular Robotic Systems

This paper surveys modular robot systems, which consist of multiple modules and aim to create versatile, robust, and low cost systems. The modularity allows these robots to self-assemble, self-reconfigure, self-repair, and self-replicate. Therefore, the surveyed research covered the previous characteristics along with evolutionary robotics and 3D printed robots. These fields are interdisciplinary, so we organize the implemented systems according to the main feature in each one. The primary motivation for this is to categorize modular robots according to their main function and to discover the similarities and differences of implementing each system.
