			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]].

This is about:
* Using (A) macrsocale to mesoscale robotic devices to
* assemble (B) nanoscale to microscale products.

== 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)
