So, this came up for me recently. Kawasaki robots used to be Left-handed. I remember learning on them, since they were my first robots. And the Kawasaki documentation as recently as the C model controller still officially says that Kawasakis run Left Hand Rule.
However, I'm reasonably certain that modern Kawsakis run in Right Hand Rule -- however, I haven't touched a Kawasaki in... 15 years? RDK appears to agree with me, and a very quick-and-dirty test after I downloaded the Lite version of K-ROSET also seems to run RHR, although I haven't figured out how to choose specific controller generations in K-ROSET.
I also noticed that the RDK Kawasaki model appears to have "Base 0" rotated 90deg around Z relative to the "front" and "back" of the robot mounting base, as compared to ABB, Fanuc, and KUKA, so that Y+ points "forward" and X+ points from "left" to "right" (from a viewpoint standing behind the robot, where the cables plug into the base).
I'm trying to use RDK to convert a large amount of point data from Kawasaki to Fanuc, so I'm interested in how RDK is modelling the Kawasaki, and if there's any known "gotchas" that I need to look out for relating to the geometry.
