Due to inevitable power dissipation, it is said that nano-scaled computing devices should perform their computing processes in a reversible manner. This will be a large problem in constructing three-dimensional nano-scaled functional objects. Reversible cellular automata (RCA) are used for modeling physical phenomena such as power dissipation, by studying the dissipation of garbage signals. We construct a three-dimensional self-inspective self-reproducing reversible cellular automaton by extending the two-dimensional version SR(8). It can self-reproduce various patterns in three-dimensional reversible cellular space without dissipating garbage signals.

SUMMARYWe have designed self-reproducing cellular automata based on two-and three-dimensional self-inspection, and emphasized the importance of simulating the intercellular transitions during the design phase. In particular, to understand the behavior in three dimensions, viewing the video image is essential. In this paper, we present videos generated by a simulation tool we built and demonstrate the operation according to the designs of previously designed self-reproducing cellular automata.
