Abstract: A method for operating an assistance system based on an attribute space obtains task information defining a target state and initial state information of an autonomous device or a user, and of an object. A planning problem is defined based on the task information, the initial state information, and further based on attribute information related to the object. The method selects an action to solve the planning problem. A control signal to a human-machine interface HMI or the autonomous device for achieving the target state is generated and output. The method decomposes, in case of determining that the selected action does not achieve the target state, the planning problem based on the attribute information to generate a decomposed planning problem, solve the decomposed planning problem, and generates the control signal based on the solved decomposed planning problem.

Abstract: Method for operating an assistance system based on an attribute space comprises: obtaining task information defining at least one target state to be achieved; obtaining initial state information defining an initial state of an autonomous device or a user, and of at least one object involved in achieving the target state; defining a planning problem based on the task information, the initial state information and attribute information related to the object; selecting an action or a sequence of actions to solve the planning problem; and outputting a control signal to a human-machine interface HMI or the autonomous device for achieving the target state; determining whether the action or sequence of actions achieves the target state, and, if not, decomposing the planning problem based on the attribute information to generate a decomposed planning problem; solving the decomposed planning problem; and outputting the control signal to the HMI or the autonomous device.

Abstract: The present invention provides a robot system for learning one or more new semantic relations in a knowledge base of physical skills. The system is configured to obtain knowledge on a physical skill by observing a demonstration, by a human user, of the physical skill, update the knowledge base with the obtained knowledge, generate a hypothesis of using the physical skill in a different context compared to a context of the demonstration by performing similarity considerations on the knowledge base using the obtained knowledge, present the hypothesis to the human user, receive a confirmation or a refusal from the human user with regard to the presentation of the hypothesis to the human user, and update the knowledge base according to the hypothesis in case of receiving the confirmation or discard the hypothesis in case of receiving the refusal.
