Microbots are tiny robots, often measuring just a few millimeters in size, designed to perform specific tasks. They can be made from various materials, including metals and polymers, and are often powered by external sources like light or magnetic fields. Microbots have applications in fields such as medicine, where they can deliver drugs directly to targeted areas in the body, or in environmental monitoring, where they can help detect pollutants. These miniature robots can be controlled individually or in swarms, allowing for complex operations. Researchers are exploring their potential in nanotechnology and robotics, aiming to enhance their capabilities for tasks like surgery or pollution cleanup.
