John von Neumann's Universal Constructor is a self-replicating machine in a cellular automata (CA) environment.

Description

It was designed in the 1940s, without the use of a computer.

The fundamental details of the machine were published in von Neumann's book Theory of Self-Reproducing Automata, completed in 1966 by Arthur W. Burks after von Neumann's death.

Von Neumann's specification defined the machine as using 29 states, these states constituting means of signal carriage and logical operation, and acting upon signals represented as bit streams.

A 'tape' of cells encodes the sequence of actions to be performed by the machine.

Using a writing head (termed a construction arm) the machine can print out (construct) a new pattern of cells, allowing it to make a complete copy of itself, and the tape.
