A mobile virtual character with emotion-aware strategies for human-robot interaction

Emotions may play an important role in human-robot interaction, especially with social robots. Although the emotion recognition problem has been massively studied, few research is aimed at investigating interaction strategies produced as response to inferred emotional states. The work described in this paper consists on conceiving and evaluating a dynamic in which, according to the user emotional state inferred through facial expressions analysis, two distinct interaction strategies are associated to a virtual character. An Android app, whose development is in progress, aggregates the user interface and interactive features. We have performed user experiments to evaluate whether the proposed dynamic is effective in producing more natural and empathic interaction.FAPESP (São Paulo State Research Support Foundation) (grant 2014/16862-4

Uma plataforma aberta e de baixo custo de robô móvel para propósito geral

Pesquisas na robótica móvel tem sido impulsionadas pelos avanços tecnológicos. Existem frentes de pesquisas que abordam diferentes aspectos e desafios da robótica móvel, dentre os quais é possível citar tópicos como locomoção, navegação e arquitetura de controle. Esse crescimento em pesquisas acarreta uma maior necessidade por plataformas de robôs que possam ser destinadas à pesquisa e também para fins educacionais. Este trabalho propõe uma alternativa de plataforma de robô móvel de baixo custo, de arquitetura de hardware, software e controle aberta, destinada a atividades de propósitos gerais. A plataforma almeja a facilitação e flexibilização do processo de desenvolvimento de estudos e aplicações robóticas por meio de uma interface de comunicação simplificada e pela abstração da heterogeneidade dos dispositivos periféricos de hardware, sendo assim, capaz de oferecer maior liberdade em relação às linguagens de programação, paradigmas de controle e tecnologias de controle

Environment for teaching and development of mobile robot systems

Using robots for teaching is one approach that has gathered good results on Middle-School, High-School and Universities. Robotics gives chance to experiment concepts of a broad range of disciplines, principally those from Engineering courses and Computer Science. However, there are not many kits that enables the use of robotics in classroom. This article describes the methodologies to implement tools which serves as test beds for the use of robotics to teach Computer Science and Engineering. Therefore, it proposes the development of a flexible, low cost hardware to integrate sensors and control actuators commonly found on mobile robots, the development of a mobile robot device whose sensors and actuators allows the experimentation of different concepts, and an environment for the implementation of control algorithms through a computer network. This paper describes each one of these tools and discusses the implementation issues and future works. © 2010 IEEE

TAO - A software platform for autonomous mobile robots

To date, different techniques of navigation for mobile robots have been developed. However, the experimentation of these techniques is not a trivial task because usually it is not possible to reuse the developed control software due to system incompabilities. This paper proposes a software platform that provides means for creating reusable software modules through the standardization of software interfaces, which represent the various robot modules. © 2012 ICROS

A self-healing architecture for Web service-based applications

Web service-based application is an architectural style, where a collection of Web services communicates to each other to execute processes. With the popularity increase of developing Web service-based application and once Web services may change, in terms of functional and non-functional Quality of Service (QoS), we need mechanisms to monitor, diagnose, and repair Web services into a Web Application. This work presents a description of self-healing architecture that deals with these mechanisms. Other contributions of this paper are using the proxy server to measure Web service QoS values and to employ some strategies to recovery the effects from misbehaved Web services. © 2008 IEEE
