Default Stephen Hawking's Interstellar Spaceship Proposal (And More!)

DARPA is funding methods of getting separate components to self-assemble and
form larger satellites and also self-assemble to form robotic rovers:

Finally, nanotechnology can now fulfill its potential to revolutionize
21st-century technology, from the space elevator, to private, orbital
launchers, to 'flying cars'.
This crowdfunding campaign is to prove it:

Nanotech: from air to space.

You may be thinking of self-reproducing which is different from
self-assembly. Self-assembly can be done at the macroscale. Considering the
advances in nanoscale devices it should be doable at the nanoscale.

Suppose we made the probes at the virus or bacteria scale then used
self-assembly to form a macroscale spacecraft say size of Mars Pathfinder.
Then we might only need a ground laser of currently existing size, say a
few
hundred kilowatts, to send multiple nanoscale components to relativistic
speeds.

Know of references for doing self-assembly with components at the
nanoscale?

You think that you can put a computer/assembly line inside
a nano particle?
Please show us how.
It should be able to go after raw material in space,which
needs oodles of energy.
What useful amount of energy can you store in a nano particle?
Where does the particle get the ions to to travel millions of miles?

I think a minimal self-reproducing craft would weight several tons,
and be anything but small.
