Um, do you mean, "Caravan", as in "Dodge Caravan", the SUV, or do you
mean it's as big as a string of camels and stuff across the desert?
;-)
And, the more important question - _would_ it run, if pressed into
service? It's true, there are considerations when scaling stuff, but
I've seen pictures of HUGE hydroelectric generators - why not a HUGE
motor?
Or is your point that robots are stupid?
Speaking of stupid specifications, I was in on writing a transformer
spec one time for a very weird power supply - I don't remember the
exact numbers, but this tranny had two secondaries, but it was
guaranteed in the spec that only one of them would be used at any
time. I was only a tech, but I tried to explain to the PHB, "You
don't need to spec the tranny to use both secondaries simultaneously
- you could spec this thing about 33% smaller (or whatever the figure
was)" but he overrode me, ordered the oversized transformer, and when
it came in, it didn't even fit in the enclosure.
When I showed the guy, "Um, Tom, when I mount the tranny here, I
can't put the lid on the box", he was mortified. "OK, it was my
goof."
It was strangely unsatisfying. It could have been an "I told you so"
moment, but I actually felt pity for the poor dimwit. Oh, well, I
guess he's just another example of the PHB syndrome.
Thanks,
Rich
