This document discusses nanorobotics and its applications. It begins with an introduction to robotics in general before focusing on nanorobotics, which deals with robotic devices at the nanoscale level. Nanorobots could have a variety of medical applications, such as detecting pathogens in the bloodstream or acting as a mouthwash. Fractal robots are also discussed, which are modular robotic structures made of interconnected cubes that can rearrange themselves into different shapes. Fractal robots may one day be used for tasks like construction or repairing themselves. The document concludes by emphasizing the promising potential of nanorobotics technology.
