bullet3/data/quadruped/minitaur_fixed_all.urdf
Erwin Coumans 4db6fa9e29 update minitaur.py to use minitaur.urdf (instead of quadruped.urdf), also sort the legs in the same order as real hardware
added test urdf files for minitaur with all fixed joints, or fixed knees.
added some stiffness/damping to minitaur legs (testing)
tiny_obj_loader, don't crash on invalid texture coordinates
