Micro robots are tiny machines, often measuring just a few millimeters or even smaller. They are designed to perform specific tasks, such as moving through narrow spaces, delivering drugs, or conducting inspections in hard-to-reach areas. These robots can be controlled remotely or programmed to operate autonomously, making them useful in various fields, including medicine and engineering. Researchers are exploring the potential of micro robots in medical applications, such as targeted drug delivery to treat diseases like cancer. Additionally, they can be used in environmental monitoring to assess pollution levels or in manufacturing for precise assembly tasks. Their small size allows them to navigate complex environments where larger robots cannot operate effectively.
