Can I use mujoco xml models available at bullet physics GitHub https://github.com/bulletphysics/bullet3/blob/master/data/mjcf/humanoid_symmetric_no_ground.xml without MuJoCo license for commercial use or would I need a license for the XML? I want to use the MuJoCo XML model and use the bullet engine for simulation.
I am not sure if Roboschool is not using the Mujoco XML models. It does use pybullet, so it may be the best shot for you.
