Keeping EVAs to a minimum is a good goal.

A better robotic hand has other uses than space assembly.
If they're marketable, manufacturing runs could be large. Then the unit
cost could be low.

But it does not reduce the difficulty of 'building a ship in a
bottle'. It works for ISS because you are plugging modules into a
shell already built and rigged, and launched with the hard-to-rig bits
(ECLSS etc) already installed. Building in space means rigging all
those cables, pipes, ducts, etc... It also means doing the hard bits
in space, rather than on the ground.


If teh bits are hard, then obviously too little engineering was applied to
make it simple. IN fact, its not clear why humans should be involved at all -
they should go up in the last flight, have their ship dock with the assembly
from the previous launches and fly off.

You know, this isn't 19th century and we are not dealing with sailing ships.

The worlds maritime and aeronautical engineers and their customers
await your instructions on how to cure the current situation with
bated breath. They've been try to solve this problem with limited
success since the early part of the 20th century. A life of fame and
fortune will be yours when you reveal the secret that has eluded
hundreds of thousands of engineers, planners, builders, etc... across
the last century.

I suppose pixies and fairies will the construction and installation?

You know, you are utterly without a clue as to how complex these
things are and how difficult assembly and maintence really is.

Certainly. But that's what conning a ship s as well, issuing orders
to the Helm.

Back in the good old days of wind-driven sea travel, there were firms
competing to send pilots out to arriving ships to bring them into
harbor; since the first pilot to arrive would generally be the one to
get the job and make the money, building high speed pilot boats became a
worthwhile endeavor, and their design formed the foundation from which
the racing yacht "America" sprang.
