— A sensor-based model of a service robot's environment is a prerequisite for interaction. Such a model should contain the positions of the robot's interaction partners. Additionally to the actual positions of the partners it is important for the service robot to predict their possible future positions. This knowledge could for example be used to realize(More)
— Robot perception still lacks reliability in complex natural environments. A commonly used method to improve perception is to incorporate more sensors with different modalities. This leads to increased computational requirements due to the parallel processing of huge amounts of sensor data. Appropriate sensor fusion methods are needed if contradictory(More)
— Experiments showed that Hierarchical Task Network (HTN) planners are suitable to find solutions for non-trivial tasks in complex scenarios. Mobile service robots are able to execute actions which may constitute the basic building blocks to achieve high-level goals. However, only few experiments demonstrate the application of a general purpose deliberative(More)
— General purpose service robots are expected to deal with many different tasks in unknown environments. The number of possible tasks and changing situations prevent developers from writing control programs for all tasks and possible situations. Complex robot tasks are thus accomplished by sequential execution of less complex robot actions that are(More)
