Robotics: Self-replication from random parts
Saul Griffith1, Dan Goldwater1 & Joseph M. Jacobson1
Abstract
Autonomously self-replicating machines have long caught the imagination1, 2, 3 but have yet to acquire the sophistication of biological systems, which assemble structures from disordered building blocks. Here we describe the autonomous self-replication of a reconfigurable string of parts from randomly positioned input components. Such components, if suitably miniaturized and mass-produced, could constitute self-fabricating systems whose assembly is brought about by the parts themselves.
