A few weeks ago, we all met up in person and had a fun, productive, and intense week! Working in three teams, we made significant progress across three fronts: integrating the MuJoCo simulator, simplifying our configurations, and advancing our theory!
All three teams made significant progress during that week and presented their advancements in this meeting. In the end, there is also a fun prize!

For those who are curious, you can find the MuJoCo integration prototype here: wip: MuJoCo Simulator Prototype by jeremyshoemaker · Pull Request #853 · thousandbrainsproject/tbp.monty · GitHub
The Hydra config simplification is already merged into tbp.monty and was summarized by @tslominski in this thread: We changed how configurations work (again)
In the next weeks, we will release research meeting recordings that go into the new theoretical ideas in more depth
