Self-replicating nanobots are robots built using nanotechnology that are able to perform programmed functions and reproduce. ... Many researchers in nanotechnology lack equivalent expertise in artificial intelligence.

Can nanobots actually exist?

Nanobots are not real and do not currently exist. There are many challenges related to creating a nano-sized robot. In the future, nanobots might exist and might be able to do useful things. Future examples of nanobots include applications in medicine.

Are there self-replicating robots?

A self-replicating machine is a type of autonomous robot that is capable of reproducing itself autonomously using raw materials found in the environment, thus exhibiting self-replication in a way analogous to that found in nature.
