I may have asked this before, but I have A Project in mind. This
is much simpler than the last time, when I wanted to build 4 humanoid
robots to pick up a shipping container at the corners and move it.
"Hup, hup, hup, ... detail halt!"
What I want to do this time is to just "slide an I-beam under the
outbuilding, attach a wheeled unit to each end, pivot the building and
roll it to when I want it." No doubt "A simple procedure involving
lasers." I'm sure. Somewhere.
But, my question is: load capacity of the units. Assume a GW of 3
tons, does that meant that each wheeled unit has to be able to 'carry'
a three ton load, or can I divide the gross weight by 4, add a "fudge
factor" and hope for the best?
This is one of those things I'd talk to one of the old guys, but I
find I am one of the old guys.
What are the dimensions of the building, is it empty or full, what is
the floor construction and how far do you need to move it in a lineal
direction?
One is 10'x16'by16' high, "framed" floor with 9/8 T&G flooring
glued & nailed. It's rotating 90° and moving ~20 feet more or less.
The other is 10'x12'by10' high. Also going to be rotated, but
moved about 30 feet.
The Big One is 26 by 32 and two stories. It is jut going to get
rotated. But I might add a basement while I have it off the piers.
Is it sturdy enough to allow that manhandling? Have you weighed it?
Also, how high do you need to lift any of these buildings? What's the
soil like where you want a basement? I'm guessing you want beams to
remove the robots from the vicinity of the excavation so you won't
have to worry about cave-ins. Das some ambitious chit, mon.
Once the preliminaries are done, then Ill be scaling down to move
my footlockers around. (I had this idea for a camp setup, using a
20' shipping container as a base, and outfitting the Clanks with
appropriate livery, depending on if I'm reenacting medieval or
Steampunk. But that's a digression.)
Clanks? Which def?
https://www.urbandictionary.com/define.php?term=Clank
"... clanks (impossibly advanced steampunk robots), dirigibles and
walking gunboats of the world there are constructs – biological
creations which range from Frankenstein-style creatures to talking
cats and mouse-sized mammoths."
https://en.wikipedia.org/wiki/Girl_Genius
What I'd really like to know is: how do I calculate the load
bearing capacity needed by the robot which is going to pick up the
corner.
Why calculate when you could overengineer the things so they could
heft the large buildings onto a single corner with one hand? Compete
with Optimus Prime. (He'd have the calcs handy, but go with 25T.)
Going out on a limb, I'm guessing you can rule out pneumatics here.
Changing approaches, decided I can't just roll any of this over
the Missus's Daisys, so I want to use a couple Rocs. Maybe some
griffins. Now I all need to know what the tension on the straps to the
harness will be.
And where I can lay my hands on a couple environmentally friendly
and sustainably sourced elephant carcases, but that's getting off
track.
