soft AP block positional assembly
Systems of T.Level I could be two dimensional arrays of robotic manipulators out of atomically precise blocks and other AP base structures on a self assembled scaffold on a chips surface. Building in the third dimesion may unnecessary complicate design because a layered configuration is a natural choice favoured by scaling laws.
This arrays could be produced by some method between
- exponential assembly
- a pritive form self replication using use pre-built blocks and external signals from broadcast channels of the chips surface.

Mascroscopic design examples
There where already several block based self replication systems proposed designed and built.
One example of those can be found here thingiverse_thing:978
The shapelock-reinforcement concepts for more advanced stages may be applicable even at this early stage - see: structural elements for nanofactories.
[Todo: add more examples]
Why many macro self replicating designs are limitedly applicable for nano self replication designs
An actual implementation will be more on the exponential assembly side and less of a "nonproductive replicator" (KRSM classification) since it moves out necessary structure nd makes design simpler.
Differences to most macroscopic models in existence capable of partial structural replication are:
- the blocks / parts will have different properties (low stiffness, low smoothness)
- the actuation method will differ (fast alternating big scale electric field / slow chemical stepping)
- the actuation method will differ multiple highly localized embedded motors are infeasible in early stages (except slow DNA walkers maybe)
- the system may be two dimensional
- a productive instead of a non-productive replicator is wished for - read "has economical motivation"
To investigate:
- minimal set of building blocks for productive exponential assembly system
- How to assemble the materials used in the next technology level with the here present block based nanosystems?
Simple Linkage manipulators
- inspirations from from 3D printer designs RepRap Morgan RepRap Wally
- inspirations from MEMS designs ... e.g. [1]?
- learn from paper stripe hinge mechanisms? Seam hinges between structural DNA bricks?
MMCS

- (To investigate:) How long range is the order in protein crystals?
