I have started helping engineer a waterjet saw (at work). Similar but a
miniature version of this:
Not commands, but work orders would be uploaded over wireless local network.
Software would control the arm to direct the waterjet, with about 30 tons per
square inch of pressure. Software would also control a suction device. The
water allows for cold cuts, so steel and stone don't burn or discolor. The
reason it will be miniature is because its for a specialized task, only one
of them will ever be made, so the software isn't really distributed if I
compile it natively. Often these machines run DOS. Linux would be more
flexable; the gui would be easy to modify, additional tasks, like inventory,
are easy to add. The hardware for this saw might take 2 years to build and
test, the software is the last thing needed. It doesn't necessarily need to
be a hardened machine, but there's a fair chance this machine will be online,
so it needs some defense. In general the software will need to be failsafe.
There's too much pressure and the material is too expensive for the saw to
make mistakes because of the software. It can't crash. It would also be easy
to convince these guys to send regular donations when they upgrade.
