Somewhat. The free educational license was only acceptable for 'personal' projects, so not suitable for class work.

Surely that kind of use would have been fine. What they're trying to do with that questionnaire must be to determine if you're making money from the venture. You can share your diary with others and still call it personal, after all. (Once you get a publisher involved, not so much.)

as an undergrad in the 90s I invested thousands of dollars of my own money to work on machine learning. Worth every penny, even if I had to miss out on some cool parties.

Wonderful that you had thousands of dollars as an undergrad to be able to do so.

Working in undergrad isn't a common thing?

Pretty sure this was just a reaction to losing so much mindshare to Brax since that came out.

My understanding is that DeepMind did not previously own MuJoCo, but today they have acquired it and released it for free. On the other hand, Brax is developed by Google and is written using Jax (which DeepMind loves and uses extensively). Why would DeepMind have been concerned that people were switching to Brax?

Good point, I was not aware that Deepmind aquired MuJoCo recently.

For undergrad students trying to dabble in reinforcement learning, several hundreds of dollars can be quite a lot.

But they can accept that the world is not geared towards amateur dabblers, and that a few hundreds of $ for a license (a license, meaning to legalize production usage, you can always copy from somewhere to "dabble") is nothing.

Well now they don't have to, because it really is nothing.

MuJoCo is the standard in much of robotics, and recently in the Deep RL space. When I was learning Deep RL, I edged on what could be done through OpenAI gym, or self-made environments, I decided to begin working with MuJoCo. But for an undergrad student from a developing country, the fees were extremely high. So, I just didn't go forward with Deep RL much. I dabbled for a while and tried using PyBullet. Did not go th…

I similarly did not get in to using MuJoCo because I want all my work to be reproducible with open source. So I spent time trying to get RL working in Godot video game engine, but ran in to some road blocks. I know MuJoCo already has all the necessary pipelines so this is exciting indeed!

Well, if you're working to pay your rent, bills, and food expenses, and you're only working part time (because you're a full time undergraduate student), you may not have a lot left over to pay for software licenses.

My uni was not rich enough to have an email server for students. So, I did not have a uni mail address. That was required.

go to literally any college you can probably walk to one near you if you live in a city, sign up for a basic program, and get a free email address. sounds dumb, but if you sign up to talk an extra language you'll have your email address you so desperatly need in your life

It seems great, but the simulation geometry options feel bit limited? What would be really great would be the ability to simulate scenes with objects imported from STEP/IGES files, so you can do more of the modeling in actual CAD tools. Instead, MuJoCo seems more oriented towards using its own primitives, not sure how that works out with more complex situations.
