“…In the context of abstract tile pattern self-replication model, it is tempting to draw a comparison between the CA-based self-replication loops [15]. In particular, the parameters, such as loop sizes and replication periods of different CA based self-replicating loops resemble with the terms, pattern size and replication time of the abstract tile pattern self-replication model.…”

This paper presents a simulation framework in which a pre-assembled rectangular pattern of DNA tiles can be put together with sets of other DNA tiles to autonomously assemble replicas of itself in a discrete two-dimensional grid.The simulator implements both abstract and chemical kinetics based modelling to simulate the tile pattern self-replication. While the abstract model uses only logical matching between the edges of tiles to guide the assembly process, the chemical kinetics model calculates stochastic preference for attachment and/or detachment of each tile during the self-replication. A comparison is made between pattern self-replication timing in the abstract model and cellular automata based models. Simulation of chemical kinetics behaviour shows that the physico-chemical parameters of tile self-assembly govern the tractability of self-replication process and reliability of replicating patterns. Observations are made about the limitations of the simulator, and a few suggestions for improvement and further studies are discussed.

“…Von Neumann found that the large state space was necessary for self-replication. Over the years, his schemes have been simplified and extended (Chou and Reggia, 1998;Nobili et al, 1994;Penrose, 1958Penrose, , 1959Sipper, 1998), though they have never been realized in practice. The rules of cellular automata are arbitrary and disconnected from fundamental physical constraints that apply to actual objects like colloids, which are subject to thermal fluctuations and whose interactions are limited by their surface chemistry.…”

Colloquium : Toward living matter with colloidal particles

A fundamental unsolved problem is to understand the differences between inanimate matter and living matter. Although this question might be framed as philosophical, there are many fundamental and practical reasons to pursue the development of synthetic materials with the properties of living ones. There are three fundamental properties of living materials that we seek to reproduce: The ability to spontaneously assemble complex structures; the ability to self-replicate; and the ability to perform complex and coordinated reactions that enable transformations impossible to realize if a single structure acted alone. The conditions that are required for a synthetic material to have these properties are currently unknown. This colloquium examines whether these phenomena could emerge by programming interactions between colloidal particles, an approach that bootstraps off of recent advances in DNA nanotechnology and in the mathematics of sphere packings. We argue that the essential properties of living matter could emerge from colloidal interactions that are specific -so that each particle can be programmed to bind or not bind to any other particleand also time-dependent -so that the binding strength between two particles could increase or decrease in time at a controlled rate. There is a small regime of interaction parameters that give rise to colloidal particles with life-like properties, including self-assembly, self-replication and metabolism. The parameter range for these phenomena can be identified using a combinatorial search over the set of known sphere packings. * zorana.zeravcic@espci.fr 2 CONTENTS

Abstract-A cyclic fabrication system (CFS) is a network of materials, tools, and manufacturing processes that can produce all or most of its constituent components. This paper proposes an architecture for a robotic CFS based on modular components. The proposed system is intended to self-replicate via producing necessary components for replica devices. Some design challenges unique to self-replicating machines are discussed. Results from several proof-of-principle experiments are presented, including a manipulator designed to handle and assemble modules of the same type it is constructed from, a DC brush motor fabricated largely from raw materials, and basic manufacturing tools made with a simple CFS.
