Bottom up positional assembly

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
