Bottom up positional assembly
From apm
This is about:
- Using (A) nanoscale to microscale robotic positional assembly devices to
- assemble (B) nanoscale to microscale (and eventually larger) atomically precise products.
Especially in the context of bootstrapping towards advanced productive nanosystems.
Examples
(A)
- Robo approach (in bottom up context) ... Big bottom up self-assembled robotics structures positionally assembling other really big bottom up self-assembled structures.
- Printer approach ... Bottom up self-assembled robotics just sufficient for minimal viable weak positional assembly like site-specific workpiece activation.
- Catalysis construction kit approach ... But this early beginning of formation of a kinematic loop can barely be called positional assembly yet.
(B)
- Pre-made self-assemblies as building-blocks so big that further self-assembly gets difficult but positional assembly becomes easy
- Advanced materials that are only assemblable to atomic precision via positional assembly (Highly polycyclic small molecule, spiroligomers, adamantanes, gemstones)
- Mid size foldamers (smaller SDN blocks, de-novo proteins) ... But this may run into the positional assembly redundancy blockade
