Self-Replicating Machines

Do we have self replicating machines?

Have we humans been able to make artificial physical self-replicating machines? Is it feasible to make such machines?

If those robots were self-replicating, maybe.

Certainly, professor Von Neumann: https://en.m.wikipedia.org/wiki/Self-replicating_machineWe are such machines, so we know they’re possible to make, even though we don’t yet know how to make one on Earth let alone in space.

You mean a probe capable of self-replication? They can absolutely be quite small. As a motivating example, a bacteria is capable of self-replication despite being microscopically small! Human beings are capable of self replication, along with being able to construct anything they want out of raw materials.

Please provide an explanation of what form "self-reproducing robots" would take based on the "tech we've got" in a way that applies to the context you've provided.

Maybe if we ever figure out true, self replicating nanomachines.

Still a strawman because I didn't say sci fi replicators. You could make an automated system that travels, mines, and manufactures. Like a 3D printer that prints copies of itself. That's not unbelievable.

Oh that's insane. It says it's self-replicating, but can it assemble the parts it creates or is a human needed? And what about the microchips? Those still take expensive machinery to produce, right?

Earth is full of machines that are capable of self-reproduction (e.g. bacteria), and some of them are clever enough to build rockets, so I don't think it's such a big stretch to assume that von Neumann probes are possible.
