Inelastic Rope Simulation in Brax #388

Closed jc-bao closed 8 months ago

jc-bao commented 10 months ago

Hello Brax team,

I'm interested in simulating an inelastic rope within Brax, similar to this example. When the rope transitions from a loose to taut state, it seems to mimic an inelastic collision. Given Brax's capabilities, I believe this might be feasible. Could you provide any insights or guidance on this?

Hi @jc-bao , it looks like the example you linked to is using tendons in MuJoCo, so I would take a look at the implementation here https://github.com/google-deepmind/mujoco. I'm not very familiar with the implementation but hope that helps
