Self-reproducing machines

A set of modular robot cubes accomplish a feat fundamental to biological systems.

Abstract

Self-reproduction is central to biological life for long-term sustainability and evolutionary adaptation. Although these traits would also be desirable in many engineered systems, the principles of self-reproduction have not been exploited in machine design1. Here we create simple machines that act as autonomous modular robots and are capable of physical self-reproduction using a set of cubes.
