Your author decided to write this book about Microrobots after seeing a news release by MIT about their research on Microrobots. Microrobots and other microelectronic devices were enabled by Nanotechnology first introduced by Professor Richard P Feynman who was a professor at Caltech while your author was a physics student earning the BS in physics there between 1947 and 1951. I started studying the pioneering research of Dr. Feynman after being reminded of his famous lecture titled: There's Plenty of Room at the Bottom. This discourse was presented at an American Physical Society meeting at Caltech on December 29, 1959. Dr. Feynman considered the possibility of direct manipulation of individual atoms as a more powerful form of synthetic chemistry than the techniques being used at that time. This became nanotechnology. Nanotechnology has made possible the many things we see in electronics now: the chips used in PCs, the advent of Laptop computers, mobile devices or Smart Phones such as Samsung Galaxy S3 and the Apple iPhone and Tablet Computers such as the Toshiba Thrive Tablet. And now the latest nanotechnology devices exemplified by Microrobots. These tiny devices will allow things to be done in the near future that could not be done before. This book will tell you about what is known about Microrobots at the end of 2013.
