  This study presents a theoretical model for a self-replicating mechanical
system inspired by biological processes within living cells and supported by
computer simulations. The model decomposes self-replication into core
components, each of which is executed by a single machine constructed from a
set of basic block types. Key functionalities such as sorting, copying, and
building, are demonstrated. The model provides valuable insights into the
constraints of self-replicating systems. The discussion also addresses the
spatial and timing behavior of the system, as well as its efficiency and
complexity. This work provides a foundational framework for future studies on
self-replicating mechanisms and their information-processing applications.
