Hello,
We do not provide a public test license at the moment, it was only available for a limited time and has since expired. It also says so in the text.
Members can of course use their license for both the Grasshopper and Dynamo versions of KUKA|prc.
If you would like to test the Dynamo version, you can send me an eMail and I can provide you with a temporary license. johannes@robotsinarchitecture.org
Best,
Johannes
