Cytobot - Text by M. Alan Kazlev A bot approximately the size of a cell. Alternatively, a bionano or biomeso-based and/or built or grown organic device the size and shape of a biological cell; an artificial but still organic cell that can be given instructions like any nano or mesobot.
Erotobot - Text by M. Alan Kazlev A bot designed for erotic or sexual purposes.
Knowbot - Text by M. Alan Kazlev Knowledge robot, a data miner or intelligent search agent, a type of software-only aioid, instructed by users to scan networks for various kinds of related information, regardless of the language or form in which it expressed. May be turing or subturing grade.
Mesobot - Text by M. Alan Kazlev An autonomous device or structure, whether sentient or non-sentient, of mesoscale size (generally 10-7 to 10-6 m); very large nanodevices like foglets and cytobots. May be organic and biological, mechanical and aioidal, or any combination of the two.
Microbot - Text by M. Alan Kazlev Autonomous device on the microscale (10-6 m); larger than a nanobot but smaller than a macroscopic bot (the limit is usually set somewhat arbitrarily at one millimeter). Microbots are used for a variety of tasks such as monitoring, repairs, nanite transport and production and smart materials.
Mitebot - Text by M. Alan Kazlev Microscopic or near-microscopic organic or mechanical robot, usually arachnid-like in form. Similar to a gnatbot except that it crawls rather than flies.
