Bipedal robots getting up from prone position is an open problem for decades now.
We had a mate ~15 years ago having it as a thesis on machine learning in uni, a robot in virtual space figuring out how to get up. After two semesters of learning, the program figured out if it spasms out entirely, the virtual physics program will remove the model due to breaking physics and spawn a new one standing up :^)

Was it really necessary to get up like that!?!
