Microrobots are small robotic devices that can navigate and perform tasks at the micro and nanoscale. Synonyms for microrobot include nano-robot, microbot, nanorobot, micromachine, nanomachine, microscale robot, and nanoscale robot. These tiny machines are designed to carry out a range of functions, from performing medical procedures to exploring environments that are too dangerous or inaccessible for humans. Microrobots are made using a variety of materials, including metals, polymers, and biological components. With continued advances in technology, it is likely that these tiny machines will become even more advanced and versatile, opening up new possibilities for scientific research and practical applications.
