“…The processes are normally realized in a distributed and stochastic manner, that is, once a set of experimental conditions is invoked, components act in parallel, intrinsically following local causal rules imposed by the system. Inspired by various instances that demonstrate self-assembly in nature, we have constructed an experimental platform to analytically investigate the properties of self-assembly (Miyashita, Casanova, Lungarella, & Pfeifer, 2008;Miyashita, Go¨ldi, & Pfeifer, 2011).…”

Self-assembly is a phenomenon broadly observed in nature where a vast number of various molecules spontaneously synthesize complex structures. In this article, prompted by the need for the realization of highly autonomous selfassembly systems that employ magnetism as a driving force, we discuss fundamental issues associated with magnetically driven self-assembly systems. We first introduce some examples from our case studies, in which the models all subscribe to a distributed approach, and thus lack central control. Then we categorize them by their type of magnetic attachment. The issues discussed include several fundamental properties, such as the effect of morphology, stochasticity, the difference between two-dimensional models and three-dimensional models, emergence, allostericity, and parallelism. The conclusions obtained support our stance that the appropriate morphology lightens the control cost for the assembly, providing primal but engaging instances of magnetic self-assembly systems that warrant further study.

“…However, their limitation is the existing trade off between the adhesion effectiveness and the biocompatibility of the adhesive. Outside the clinical setting, alternative approaches exist to name but a few, such as utilising the van der Waals force [9], [10], [11], surface tension [12], [13], [1], electrostatic force [14], or ice freezing [15]. However, these existing approaches require a physical access to the injury site and some are designed for single use and lack the autonomous operation.…”

“…Through the connections, the implemented circuits can be further extended to the connected modules. Hydrogen bonding using a thermal cycle is proposed by Miyashita et al (2008). The mechanism exploits the characteristics of the media (water, in this case) and changes the physical phase from liquid to solid, depending on the temperature.…”

We present a scheme of two-dimensional module reconfiguration based on interactions between microscale magnetic modules with potential applications in micro-robotics, particularly in automatic micro-fabrication, non-invasive diagnoses, micro-surgery, and drug delivery at unreachable sites. The approach taken is a mixture of a top-down engineering approach and a bottom-up self-assembly approach, where reconfiguration commands are delivered from outside the workspace in the form of a magnetic field, which directs configuration changes in the set of modules by changing the strengths of individual magnetic moments. The magnetic modules in the study, 750 µm in size, are constrained to a liquid surface, providing a simplified two degrees of freedom translational motion environment, where the laterally interacting inter-module magnetic force determines the assembly configuration. In this way, the relative distance of the magnets simply reflects the strength of the interactions, and thus easily enables the design of the system's reconfiguration scenario. Reconfiguration occurs when the magnetic attractive forces are changed. To direct the assembly morphology in a controlled manner, the modules are addressed magnetically by incorporating a different magnetic material into each module type, each with different magnetic hysteresis characteristics. For addressing different modules' magnetizations, we incorporate three different magnetic materials that feature different magnetic coercivities. This allows for the independent control of the magnetization of each material using applied external fields of varying strength, leading to arbitrary configuration change in a three-module set and limited control over a four-module set. General cases with more than five modules are further discussed.
