Nanorobotics is a field that seeks to create very tiny robots. It combines the engineering requirements of robotics with the scale of nanotechnology to build machines that are as small as the very molecules that make up matter.

In 1959, the famous American physicist Richard Feynman gave a talk entitled, “There’s Room at the Bottom”. In it, he mentioned a device that could write “The Lord’s Prayer” on the head of a pin. Then he asked, “Why can’t we write the entire 24 volumes of the “Encyclopaedia Brittanica” on the head of a pin?” The talk was an eye-opener that inspired many engineers and arguably sparked the beginning of nanorobotics.
