This paper proposes a universal constructor implemented on a selftimed cellular automaton, which is a particular type of asynchronous cellular automaton. A binary digit is represented by the presence or absence of a pulse at a given position at a given time, and since the pulses circulate around the system, the digit is not stored in any fixed position.

A selfreplicating machine is a type of autonomous robot that is capable of reproducing itself autonomously using raw materials found in the environment, thus exhibiting selfreplication in a way analogous to that found in nature. It is argued that the transition from asexual to sexual reproduction necessitates a change in number and structure of the genetic tapes involved.
