Last I had heard, the KRC... 6?... was supposed to come out soon, with an option for either KSS/KRL, or Sunrise/Java (as on the iiWA). But that was about a year ago.The KRC4 continues to get evolutionary updates, and KSS 8.6 / WorkVisual 6 just came out (or is in beta release, I'm not sure).
The KRC1 and KRC2 had a similar evolution path. The entire industry has a "if it ain't broke, don't fix it" mentality, so any major changes or releases are pretty far apart, with small updates/upgrades in between.
As far as the Medea purchase, the one major change I know happened is that KUKA Aerospace had to be spun off as a separate company (due to federal regulations concerning Aerospace and Defense work), and was soon after bought by another American aerospace supplier.
Thank you very much, SkyeFire. I am actually not a guy from this area, but focusing on investment. So I would really value the ideas from experts in this forum, like you For the past couple of months, I was told KUKA was in some kind of dilemma, as the Rueter has left, those top guys changed a lot and even some guy from China told me he had not seen KUKA`s new product initiation for long time (which I presume he meant KUKA`s totally new model, not those modification ones). These news worries me with the pretty unfavorable financial report of 2018. But now I saw your message listing a bunch of new products which has been and will be released, I feel quite excited about it. At least it means the situation is now as bad as those rumors said. Thank you very much.
