Self-assembling modular robotic systems are swarm robotics that allows for the assembly of different complex robotics configurations from individual modules. Creating an adaptable and capable robotics system. Such systems are applicable to unpredictable environments such as search and rescue and can further improve efficiency in the logistics industry. This project presents the design and manufacturing of such a system. Each module has 4 degrees of freedom, wheel-based locomotion, wireless communication, and an electromagnet connection system. The system control is achieved utilizing AprilTags, OpenCV, and several PID controllers. Tests of mechanical performance, automated load carrying, and automated self-assembly were conducted to validate the performance of the system as a whole.
