Nanorobotics - Part 2
Another important document in the history of our subject
is Nanosystems: Molecular Machinery, Manufacturing, and
Computation, by K. Eric Drexler (1992). William A. Goddard
III, Professor of Chemistry ans Applied Physics at the
California Institute of Technology, said that with this
book Drexler has established the field of molecular nanotechnology,
and that the detailed analyses show quantum chemists and
synthetic chemists how to build upon their knowledge of
bonds and molecules to develop the manufacturing systems
of nanotechnology, and show physicists and engineers how
to scale down their concepts of macroscopic systems to
the level of molecules.

In the book, Drexler assembles the conceptual
and analytical tools neded to understand molecular
machinery and manufacturing, presents an analysis
of their core capabilities and explores how present
laboratory techniques can be extended, stage by stage,
to implement molecular manufacturing systems. Marvin
Minsky, with an eye in the future, read the book and
said that devices enormously smalller than before
would remodel engineering, chemistry, medicine, and
computer technology. He even added: "This is
the book for starting the next century of engineering".
Ralph C. Merkle, of Xerox Palo Alto Research Center,
said that what the computer revolution did for manipulating
data, the nanotechnology revolution would do for manipulating
matter, juggling atoms like bits. |
But many problems await researchers, and one of them
is high level programming and planning systems, which
are essential for assembling complex structures. Requicha
says that onde must begin with relatively low-level programming
primitives and build upon them constructs at a higher
level of abstraction. Which is the nanoscale equivalent
of a macrorobotics manipulation task like a peg-in-hole
insertion? So what is known about macrorobotics must be
adapted to the nanoworld. Requicha again says that new
concepts will also be needed, because the physics and
chemistry of the phenomena and objects are quite different
in these two worlds.
