 * You can specify hybrid robot with the material `gs.materials.Hybrid`, which consists of `gs.materials.Rigid` and `gs.materials.MPM.Muscle`. Note that only MPM is supported here and it must be the Muscle class since the hybrid material reuses internally the `muscle_group` implemented for `Muscle`.
 * When controlling the robot, given the actuation being from the inner rigid-bodied skeleton, there is a similar interface to rigid-bodied robot, e.g., `control_dofs_velocity`, `control_dofs_force`, `control_dofs_position`. Also, the control dimension is the same as the DoFs of the inner skeleton (in the above example, 2).
 * The skin is determined by the shape of the inner skeleton, where `thickness` determines the skin thickness when wrapping the skeleton.
-* By default, we grow skin based on the shape of the skeleton, which is specified by `morph` (in this example, the `urdf/simple/two_link_arm.urdf`). The argument `func_instantiate_soft_from_rigid` of `gs.materials.Hybrid` defines concretely how skin should grow based on the rigid-bodied `morph`. There is a default implementation `default_func_instantiate_soft_from_rigid` in [genesis/engine/entities/hybrid_entity.py](https://github.com/zhouxian/Genesis-dev/blob/main/genesis/engine/entities/hybrid_entity.py). You can also implement your own function.

 * When `morph` is `Mesh` instead of `URDF`, the mesh specifies the soft outer body and the inner skeleton is grown based on the skin shape. This is defined by `func_instantiate_rigid_from_soft`. There is also a default implementation `default_func_instantiate_rigid_from_soft`, which basically implements skeletonization of 3D meshes.
 * The argument `func_instantiate_rigid_soft_association` of `gs.materials.Hybrid` determines how each skeletal part is associated with skin. The default implementation is to find the closest particles of the soft skin to the rigid skeletal parts.
