Yeah, a good one to look at is Isaac Sim from Nvidia. It's basically like a game engine but you connect up your robot system and hook nodes in the system up to a model in the engine. It simulates physics like friction etc as well.
I think that if you can write blog phostthat linksto a repo with a demo of your product and a few images/videos of the test, it will get more upvotes from the general public.
