OMG SysML for Autonomous Systems
Written by Ricardo Sanz   
Wednesday, 21 March 2012

An ASLab Research Seminar

OMG Systems Modeling Language for Autonomous Systems

Using engineering tools in research

Ricardo Sanz

Place: Aula de Seminarios de Automática
Time: February 7, 2013 / 13:00-14:00

The OMG Systems Modeling Language (OMG SysML) is a a general-purpose modeling language for systems engineering applications.

SysML supports the specification, analysis, design, verification, and validation of a broad range of complex systems. These systems may include hardware, software, information, processes, personnel, and facilities.

The origins of SysML can be traced back to the work of the International Council on Systems Engineering’s (INCOSE) Model Driven Systems Design workgroup. In January 2001 they started a roadmap to customize the Unified Modeling Language (UML) for systems engineering applications.

In this speech we will summarily describe the SysML and explain the reasons for its potential importance in the research on Autonomous Systems.

The HPB Flagship Project has been Approved
Written by Ricardo Sanz   
Sunday, 03 February 2013
The Human Brain Project (HPB) has been approved. The proposal won the top European Science Funding as a FET Flagship Project. The project, in which UPM ASLab takes part, tries to reconstruct the brain, piece by piece, in supercomputer-based models and simulations and use them to create health and ICT technology.

The "Human Brain Project" (HBP) will build a large, multiobjective experimental facility to develop a detailed, running model of the human brain.

This model will be used to study how the human brain works and to develop technologies of applicability to humans -e.g. personalized treatment of neurological diseases- and artifacts -e.g. control systems for robots. This research lays the scientific and technical basis for neuro-inspired ICT technology that has the potential to improve enormously the quality of life of many people. Image

UPM ASLab work is focused in the construction and operation of the Neurorobotics Facility. This is an experimental platform for the evaluation of robot control architectures that have been reverse-engineerned from the brain. The purpose of this work is the creation of bodies where to exploit the computer-based, simulated brains. The robot bodies will be both virtual and physical, offering tools (the HBP Virtual Robot Designer) to researchers to customize the bodies according to their needs to perform neuroscience or cognitive science experiments. Our specific work is mostly related to the real-time computing infrastructures that are needed to couple the brains with the bodies (the HBP Closed Loop Engine) and the support of HBP researchers in the use of the neurorobotics platform for their experiments.

Emotion and the expression of action readiness

Title: Emotion and the expression of action readiness

Authors: Carlos Herrera and Ricardo Sanz

Abstract: In this talk we introduce the morphofunctional approach to emotion modelling, using the issue of emotion expression as the entry point. We consider the notion of expressive behaviour and the function of emotion expression. Based on Frijda's theory, emotions are changes in the relationship with the environment through a change in action readiness mediated by autonomic arousal. This is the basis for the morphofunctional approach, which considers systems whose morphology can be changed or modulated to provide different functionality, and the effect of such modification are changes to the dynamics of interaction. Emotion emerges from the control of bodies which can not only perform actions, but also change their readiness and the dynamic space of interaction. In this context, the expressive nature of emotion is explained by the dynamic-relational aspects of emotional behaviour. .

Models as Architectural Foundations for Interaction

Title: Models as Architectural Foundations for Interaction

Authors: Ricardo Sanz

Abstract: In this contribution we discuss the concept of action based on mental models as a grounding theory both for the analysis of biological minds and the systematic construction of artificial cognitive systems. Indeed it constitutes the cornerstone of what we would call the model-based control theory of mind. The topic of mental models have been a classic approach to the study of mind (Craik, 1943; Gentner and Stevens, 1983) focused on representational aspects. But in most cases the approach has just had an aura of metaphorical argumentation due to the lack of formalisation of the concept of model and the less than rigorous approach to the study of its use in the generation of mental activity. The approach we take here establishes that the adaptive value of model-based minds is rooted in their control-enabling capabilities while in presence of uncertainty. Minds are controllers that keep our life going —expanding our genes— by building and using models of the surrounding reality —passive and active agents—, and the inner reality —the body and the mind itself. All these become critical in the production of advanced controlling capabilities. What is also interesting from the cognitive systems point of view, is that seeing minds as just model-based controllers, sets a strong, rigorous foundation for a naturalised epistemology. Knowledge will be identified with those models and they will prove critical for survival at large in an rule-following world. Minds build and use models of the inner and the outer to keep the organism as such. Is in this model-centric aspect that we want to concentrate upon: minds exploit models of the outer to keep the inner working. .

The morphofunctional approach to emotion modelling in robotics

Carlos Herrera, Guadalupe Sánchez and Ricardo Sanz

Abstract
In this conceptual paper, we discuss two areas of research in robotics, robotic models of emotion and morphofunctional machines, and we explore the scope for potential cross-fertilization between them. We shift the focus in robot models of emotion from information-theoretic aspects of appraisal to the interactive significance of bodily dispositions. Typical emotional phenomena such as arousal and action readiness can be interpreted as morphofunctional processes, and their functionality may be replicated in robotic systems with morphologies that can be modulated for real-time adaptation. We investigate the control requirements for such systems, and present a possible bio-inspired architecture, based on the division of control between neural and endocrine systems in humans and animals. We suggest that emotional epi- sodes can be understood as emergent from the coordination of action control and action-readiness, respectively. This stress on morphology complements existing research on the information-theoretic aspects of emotion.
