Facing human activity-aware navigation with a cognitive architecture raises several difficulties integrating the components and orchestrating behaviors and skills to perform social tasks. In a real-world scenario, the navigation system should not only consider individuals like obstacles. It is necessary to offer particular and dynamic people representation to enhance the HRI experience. The robot's behaviors must be modified by humans, directly or indirectly. In this paper, we integrate our human representation framework in a cognitive architecture to allow that people who interact with the robot could modify its behavior, not only with the interaction but also with their culture or the social context. The human representation framework represents and distributes the proxemic zones' information in a standard way, through a cost map. We have evaluated the influence of the decision-making system in human-aware navigation and how a local planner may be decisive in this navigation. The material developed during this research can be found in a public repository (https://github.com/IntelligentRoboticsLabs/social%5fnavigation2%5fWAF) and instructions to facilitate the reproducibility of the results.

Robots have been proposed as teaching assistants for children, but few studies have measured their effectiveness. This paper describes an experiment using the Baxter robot for teaching basic computational principles. We compare acquired abilities in students with a control group lectured by a human teacher in a traditional way. These abilities are focused on the application of computational principles to a different domain. Experiment description, data analysis and discussion of the results are also presented in this paper.

Generation of autonomous behavior for robots is a general unsolved problem. Users perceive robots as repetitive tools that do not respond to dynamic situations. This research deals with the generation of natural behaviors in assistive service robots for dynamic domestic environments, particularly, a motivational-oriented cognitive architecture to generate more natural behaviors in autonomous robots. The proposed architecture, called HiMoP, is based on three elements: a Hierarchy of needs to define robot drives; a set of Motivational variables connected to robot needs; and a Pool of finite-state machines to run robot behaviors. The first element is inspired in Alderfer’s hierarchy of needs, which specifies the variables defined in the motivational component. The pool of finite-state machine implements the available robot actions, and those actions are dynamically selected taking into account the motivational variables and the external stimuli. Thus, the robot is able to exhibit different behaviors even under similar conditions. A customized version of the “Speech Recognition and Audio Detection Test,” proposed by the RoboCup Federation, has been used to illustrate how the architecture works and how it dynamically adapts and activates robots behaviors taking into account internal variables and external stimuli.

Any device we want to connect to a global network, e.g. Internet, should have a unique global identifier. However, the size of this identifier can be an unacceptable overhead for devices with limited resources (sensors, toys, disposable devices, micro-robots, etc.), because conventional protocols use full addresses to transmit, process, and store the data required for routing. The usual solution for such devices is to limit the address space to 1 or 2 bytes, but this sacrifices the global unicity of the identifiers. The proposal presented in this article enables devices with limited resources to use reduced addresses that globally identify hosts. We propose the use of abbreviated addresses for routing. We have developed a new protocol named ADSR that takes advantage of these new addresses. This protocol is a modified version of DSR based on the use of abbreviated addresses. The abbreviation procedure can lead to two different nodes having the same address, which we will term collision. ADSR allows rather than avoids collisions. The foundations of this protocol, and some results of an implementation are also presented in this article. [ABSTRACT FROM AUTHOR]
