Description
Summary:In order to successfully perform typical household tasks such as manipulation or navigation, domestic robots need an accurate description of the world they are operating in. Creating and maintaining such a description, in this work referred to as world model, is a non-trivial task in a domestic environment that typically has a high number of objects, and is unstructured and dynamically changing. This work introduces probabilistic multiple hypothesis anchoring to create and maintain a semantically rich world model using probabilistic anchoring. Multiple hypothesis tracking-based data association is included to be able to deal with ambiguous scenarios. Multiple model tracking is included to be able to easily incorporate different kinds of prior knowledge. ► We introduce probabilistic multiple hypothesis anchoring. ► Anchoring with multiple model tracking and multiple hypothesis based data association. ► Experimental validation of the approach in a series of challenging experiments. ► An analysis of the (im)possibilities of the method based on the assumptions made.
