As of now, nanorobots in the form of fully autonomous machines do not exist; however, researchers have developed nanoscale devices and systems that can perform simple tasks. These include drug delivery systems, targeted therapies, and diagnostic tools that operate at the molecular level. While significant progress has been made in Nanotechnology, the creation of fully functional nanorobots capable of complex behaviors is still in the experimental stage.
