   * Knobs that are rotational should rotate around Z, a light switch should also rotate around Z and X should point away from the hand, a button is a prismatic joint, so the Z should point along the joint, i.e. away from the hand. Z rule is more important than the X rule here.
+===== Modelling conventions for robots =====
+  * No self collision at initial state (like in reality)
+===== Naming convention =====
+  * Each object should have at least two folders: stl for collision and obj or dae for visual.
+  * File names should be in English and follow the convention of using capital letters to separate words, without any underscores. For example: Apple.obj, Table.obj, DoorHandle.obj, FridgeDoorHandle.obj
+  * For mesh and texture, conventions from Unreal Engine are used, Mesh is prefixed with SM_, Texture is prefixed with T_, Material is prefixed with M_. For example:
