- In this paper we suggest a biologically inspired approach to flexible behavior through emotion modeling. We consider emotion to emerge from relational interaction of body, nervous system and world, through sensory-motor attunement of internal parameters to concern-relevant relationships. We interpret such relationships with the notions of collective variable and control parameters. We introduce a simple robotic implementation of this model of appraisal, following the techniques of evolutionary neuro-robotics.

- In order to explain and model emotion we need to attend to the role internal states play in the generation of behavior. We argue that motivational and perceptual roles emerge from the dynamical interaction between physiological processes, sensory-motor processes and the environment. We investigate two aspects inherent to emotion appraisal and response which rely on physiological process: the ability to categorize relations with the environment and to modulate response generating different action tendencies.

From the virtual to the robotic : Bringing emoting and appraising agents into reality
- 2011

Ingår i: Proceedings of the 2nd European Future Technologies Conference and Exhibition 2011 (FET 11). - : Elsevier. ; , s. 241-243

Konferensbidrag (refereegranskat)abstract
- - A classical appraisal model of emotions extended with artificial metabolic mechanisms is presented. The new architecture is based on two existing models: WASABI and a model of Microbial Fuel Cell technology. WASABI is a top-down cognitive model which is implemented in several virtual world applications such as a museum guide. Microbial fuel cells provide energy for the robot through digesting food. The presented work is a first step towards imbuing a physical robot with emotions of human-like complexity. Classically, such integration has only been attempted in the virtual domain. The research aim is to study the embodied appraisal theory and to show the role of the body in the emotion mechanisms. Some initial tests of the architecture with humanoid NAO robot in a minimalistic scenario are presented. © Selection and peer-review under responsibility of FET11 conference organizers and published by Elsevier B.V.

Grounding Motivation in Energy Autonomy : A Study of Artificial Metabolism Constrained Robot Dynamics

- We present an evolutionary robotics investigation into the metabolism constrained homeostatic dynamics of a simulated robot. Unlike existing research that has focused on either energy or motivation autonomy the robot described here is considered in terms of energy-motivation autonomy. This stipulation is made according to a requirement of autonomous systems to spatiotemporally integrate environmental and physiological sensed information. In our experiment, the latter is generated by a simulated artificial metabolism (a microbial fuel cell batch) and its integration with the former is determined by an E-GasNet-active vision interface. The investigation centres on robot performance in a three-dimensional simulator on a stereotyped two-resource problem. Motivationlike states emerge according to periodic dynamics identifiable for two viable sensorimotor strategies. Robot adaptivity is found to be sensitive to experimenter-manipulated deviations from evolved metabolic constraints. Deviations detrimentally affect the viability of cognitive (anticipatory) capacities even where constraints are significantly lessened. These results support the hypothesis that grounding motivationally autonomous robots is critical to adaptivity and cognition.

An Analysis of Behavioral Attractor Dynamics

Ingår i: 9th European Conference, ECAL 2007. - Berlin, Heidelberg : Springer Berlin/Heidelberg. - 9783540749127 - 9783540749134 ; , s. 213-222

- The interaction of brain, body and environment can result in complex behavior with rich dynamics even for relatively simple agents. Such dynamics are, however, often notoriously difficult to analyze. In this paper we explore the case of a simple simulated robotic agent, equipped with a reactive neurocontroller and an energy level, that the agent has been evolved to re-charge. A dynamical systems analysis, shows that a non-neural internal state (energy level), despite its simplicity, dynamically modulates the agent-environment system’s behavioral attractors, such that the robot’s behavioral repertoire is continually adapted to its current situation and energy level.

An Oxygen-Diffusion Cathode MFC Model for Simulation of Energy-Autonomous Robots
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- We present a macroscopic mathematical model of energy generation dynamics in oxygen-diffusion cathode microbial fuel cells (ODC-MFCs). The model is phenomenologically derived on the basis of actual experimental data, obtained by a battery of ODC-MFCs connected in series that supplied energy to a physical robot prototype. Due to its limited computational overhead, the simple set of equations is particularly suitable for the study of robot adaptive behavior under naturalistic energyconstraints in computer simulations, and as a tool for the design and optimization of stack configurations of large sets of MFCs.
