 +Service robots operating in domestic environments are typically faced with a variety of objects they have to deal with to fulfill their tasks. Some of these objects are articulated such as cabinet doors and drawers, or room and garage doors. The ability to deal with such //articulated objects// is relevant for service robots, as, for example, they need to open doors when navigating between rooms and to open cabinets to pick up objects in fetch-and-carry applications.
 +
 +We developed a complete probabilistic framework that enables robots to learn kinematic models of articulated objects from observations of their motion. We combine parametric and nonparametric models consistently and utilize the advantages of both methods. As a result of our approach, a robot can robustly operate articulated objects in unstructured environments. As an illustrating example, consider the images below where a mobile manipulation robot interacts with various articulated objects in a kitchen environment, learns their kinematic properties, and infers their kinematic structure.

 +All software is available open-source (including documentation and tutorials) on [[http://www.ros.org/wiki/articulation]].
