Another interesting thing from JHU

http://urobotics.urology.jhu.edu/projects/BW/

I have _no_ idea why the urology department were interested in ball
worms. Unless they got the wrong end of the stick and thought they
were a parasite...

I expect its probably being looked at, at other places than out of the 
country Johns Hopkins facilities, and likely they are not aware of 
linuxcnc since we don't have a 6 or 8 figure advertising budget. But 
drawing such into the linuxcnc camp certainly would be a whole bunch of 
eagle feathers in our collective hat bands.  They'll need to learn just 
how versatile linuxcnc actually is.

Oh...MYGod!!

It is laser-cutting skull repair parts offline, not cutting the holes
in the skull. That would be more scary.

Would it? If it was me on the table, and the hole needing patch was in my 
skull, I think I'd rather have the piece being inserted pre-made during 
the surgical prep phase, then used as a measure/guide, and let 
lCNC cut a clean hole thats a perfect fit. Healing to useable strength 
would be many times faster if all the bone growth needed was that quite 
precisely fitted line.  There is also the possibility of fitting 
dovetailed keys to help retain it while it is healing.  Sucking up the 
debris from the machining would be a bigger problem than the machining 
itself.

In fact, let that be somebody's "next big thing".  And far less dangerous 
than the early bovee knives were.

Well, NIST did a system for ultrasonic inspection of C-5 
aircraft with a couple guys suspended by cables in a basket, 
and path controlled by G-code and the original EMC.  I 
really would NOT have wanted to work on such a life-critical 
system.  That was likely about 15 years ago.

As far as I know nobody from this project ever asked a question on the
forum or mailing list. It makes me wonder how many other "silent"
users there are out there.

I wonder if they got it working? The control computer was a small
ARM(?) based parallel port system (I have one sent as a sample by the
manufacturer)
https://www.robotshop.com/de/en/roboard-ncbox-189-cnc-machine-controller.html

I never had much luck making it work, to be honest.

Taint rocket science. This would be wrapping 3d trace data up, probably 
with some transposing between a 5 or 6 axis autoscan, and in this case a 
kins translation because the actual part could be done in a 3 axis + 
rotary table.

But the translation will have to be canned code, and taking the raw data 
to drive it may take more than the 80 minutes depending of coarse on how 
accurate it needs to be. .010 is probably not possible, but 1/16", which 
since they are growing bone to fill the gaps anyway, does seem to be 
doable once the translation code is written.

There may be problems associated with the OR sterility requirements. I 
used to know a neuro-surgeon whose OR costs were 2x most others, he 
operated in special order western boots, but the autoclave was hell on 
the boots. His home was on Rapid Creek, and he was home the night of 
June 9th, 1972. The only thing left was the slab the house sat on. His 
body was never found. One of 272 that didn't make it thru that night. 
Roy Crowder was a good man. He had the task of telling me my wife was 
dieing 3 years earlier, and did it by putting the xrays on the light box 
to show me just how serious it was. I looked at the pix for perhaps 15 
seconds and allowed as how I'd better call the kin. His answer was yes, 
I don't have the tools to do anything about it, with tears rolling down 
his cheeks. He never sent me a bill, and neither did St Josephs.
