Robot is scaled to 4 times the size of a 25' Project!
« on: June 30, 2019, 01:00:40 AM »
Hi, I'm running  a trial version of Kuka|PRC on Rhino 6, and I built my model in inches but it is almost 30 feet long.  I tried to set up a simulation printing contours with a 30/60.  I know they are heavy payload bots but I'm pretty sure the one in our shop isn't on a 100' base. Anybody know why this is and how I can fix it?  I imagine it somehow got inches and feet mixed up.  But I changed the units several ways on Rhino already with no response.

Hello,

All KUKA robots work in mm, which is why KUKA|prc always assumes your project to be in millimeters as well.
So in Rhino you will need to copy/paste your geometry into a millimeter project or change the units of your original project.
We decided that it would be better to make this a responsibility of the user, so that we don't have accidental dual conversions or rounding errors on our end (think https://en.wikipedia.org/wiki/Mars_Climate_Orbiter#Cause_of_failure). As you mentioned, the mismatch in scale can be seen clearly in the simulation.
Hope this clarifies it a bit!

Best,
Johannes
