View source for Top down positional assembly

{{stub}}

This is about:
* Using (A) macrsocale to mesoscale robotic devices to 
* assemble (B) nanoscale to microscale (and eventually larger) [[atomic precision|atomically precise]] products.

Especially in the context of [[bootstrapping]] towards [[advanced productive nanosystem]]s.

== Delineation ==

Top down positional assembly is not to be confuses with: [[Top-down manufacturing]] <br>
[[Top-down manufacturing]] also includes things like photo-lithography which is not [[positional assembly]].

== Examples ==

'''(A)''' – Listed in increasing size of manipulabe parts: <br>
* [[SPM]] microscopes for active manipulations of very small parts down to single atoms
* [[MEMS]] grippers for manipulating parts big enough to be grippable by them

'''(B)''' – Listed in increasing size of manipulated parts:
* [[Piezomechanosynthesis]] - [[direct path]]
* [[Folded-foldamer pushing approach]]
* [[Robo approach]] in top-down context (manipulating really large finished self-assemblies)
