Transferring human navigation behaviors into a robot local planner

Rafael Ramon-Vigo, Noe Perez-Higueras, Fernando Caballero, Luis Merino
2014 The 23rd IEEE International Symposium on Robot and Human Interactive Communication  
The paper presents an analysis of the performance of the controller behavior in two different scenarios interacting with persons, and a comparison of this approach with a Proxemics-based method.  ...  Observations of real human motion interactions found in one publicly available datasets are employed to learn a cost function, which is then used to determine a navigation controller.  ...  The first case is training with the data of scenario DS1 and evaluation in the same scenario (E1). The same evaluation, but with scenario DS2, is denoted E2.  ...

Human robot motion: A shared effort approach

Grimaldo Silva, Thierry Fraichard
2017 2017 European Conference on Mobile Robots (ECMR)  
One such benefit is that human-like motion was shown to reduce the planning effort for all persons in the environment, given that they tend to solve collision avoidance problems in similar ways.  ...  In contrast with such an approach, recent works have showed benefits of robots that can move and avoid collisions in a manner similar to persons, what we call human-like motion.  ...  This approach is necessary in case the person is unaware of the robot or either unwilling or incapable of changing his motion plan. Conversely, in real scenarios, a person does not always yield.  ...

A Character Model with Moral Emotions: Preliminary Evaluation

Cristina Battaglino, Rossana Damiano, Marc Herbstritt
2014 Workshop on Computational Models of Narrative  
According to appraisal models, cognitive processes have the function of building a mental representation of the situation in which a person is involved (person-environment relation).  ...  In this paper, we propose to model story characters as value-based emotional agents, who appraise their own and others' actions based on their desires and values, and feel the appropriate moral emotions  ...  In EMA [33] , the first fully-implemented framework for conversational agents, appraisal is formed by a set of independent processes that operate on a plan-based representation of person-environment relation  ...

Incorporating social practices in BDI agent systems [article]

Stephen Cranefield, Frank Dignum
2019 arXiv   pre-print
We define and implement this mechanism in Jason using a periodically run meta-deliberation plan, supported by a metainterpreter, and illustrate its use in a realistic scenario.  ...  Deliberating about interactions from fundamentals is not very scalable either, because in that case all possible reactions of a user have to be considered in the plans.  ...  In [5] there is a first formalization of all these aspects based on dynamic logic.  ...

Planning for cars that coordinate with people: leveraging effects on human actions for planning and active information gathering over human internal state

Dorsa Sadigh, Nick Landolfi, Shankar S. Sastry, Sanjit A. Seshia, Anca D. Dragan
2018 Autonomous Robots  
We first explore learning these parameters offline, and show that a robot planning in the resulting underactuated system is more efficient than when treating the person as a moving obstacle.  ...  Planning in our model results in coordination behaviors: the robot inches forward at an intersection to see if can go through, or it reverses to make the other car proceed first.  ...  Scenario 3: Make human go first In this scenario, we demonstrate that an autonomous vehicle can plan to cause the human to proceed first at an intersection.  ...

Modeling Agents with a Theory of Mind

Maaike Harbers, Karel van den Bosch, John-Jules Meyer
2009 2009 IEEE/WIC/ACM International Joint Conference on Web Intelligence and Intelligent Agent Technology  
Both approaches have been implemented in a case study, and results show that the ST approach is preferred over the TT approach. *  ...  Based on existing theory of mind theories, a theory-theory (TT) and a simulation-theory (ST) approach for modeling agents with a theory of mind models are proposed.  ...  In our case, execution of a module might result in updating its belief, goal or intention base, but not executing actual actions in the environment.  ...

Paulo H. C. Alves, Marx L. Viana, Carlos J. P. De Lucena
2017 Proceedings of the 29th International Conference on Software Engineering and Knowledge Engineering  
In this context, this paper introduces an approach that considers the agent's personality traits in order to improve the solving process of normative conflicts.  ...  However, norms eventually can be conflicting -for example, when there is a norm that prohibits an agent to perform a particular action and another norm that obligates the same agent to perform the same  ...  We used the architecture proposed in this paper (see Fig. 4 ) in the first and second scenarios.  ...
