Modular robotics refers to a type of robotic system made up of multiple interconnected modules that can work together to perform various tasks. Each module is a self-contained unit with its own sensors, actuators, and control systems, allowing them to communicate and collaborate. This design enables flexibility, as the modules can be reconfigured to adapt to different environments or tasks. The main advantage of modular robotics is its scalability and versatility. By adding or removing modules, the system can change its shape and functionality, making it suitable for applications in areas like search and rescue, manufacturing, and space exploration. This adaptability allows for efficient problem-solving in dynamic situations.
