Self-Repairing Mechanical Systems

A concept of a self-repairable mechanical system which is composed of homogeneous mechanical units is described. We have developed a modular system capable of 'self-assembly' and self-repair. The former means a set of units can form a given shape of the system without outside help, and the latter means the system restores the original shape if an arbitrary part of the system cut off. We show both of 2D and 3D unit design, and distributed algorithm for the units.
