- The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to span about four decades of energy, from a few tens of GeV to above 100 TeV with enhanced angular and energy resolutions over existing VHE gamma-ray observatories. An international collaboration has formed with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America. In 2010 the CTA Consortium completed a Design Study and started a three-year Preparatory Phase which leads to production readiness of CTA in 2014. In this paper we introduce the science goals and the concept of CTA, and provide an overview of the project. (C) 2013 Elsevier B.V. All rights reserved.

- People like to play, and robotic technology offersthe opportunity to interact with artifacts in new ways. Robots co-existing with humans in domestic and public environments are expected to behave as companions, also engaging in playful interaction. If a robot is small, we foresee that people will want to be able to pick it up and express their intentions playfully by hugging, shaking and moving it around in various ways. Such robots will need to recognize these gestures -- which we call "full-body gestures" because they affect the robot’s full body. Inertial sensors inside the robot could be used to detect these gestures, in order to avoid having to rely on external sensors in the environment. However, it is not obvious which gestures typically occur during play, and which of these can be reliably detected. We therefore investigate full-body gesture recognition using Sponge Robot, a small humanoid robot equipped with inertial sensors and designed for playful human-robot interaction.

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

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.

Modelling Embodied Appraisal in Humanoids : Grounding PAD space for Augmented Autonomy
- 2011
-
Ingår i: Proceedings of the Workshop on Standards in Emotion Modeling, 2011.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A computational emotion architecture is presented which grounds an aspect of an appraisal theoretic architecture in energy related processes. The incorporation of an energy constraint on emotional-cognitive behaviour allows greater potential for autonomous agency when implemented on a physical (NAO) robot platform. In this paper we present an algorithm that enables metabolic grounding of the arousal component of the PAD emotion space used in the architecture. We describe an exemplar problem that abstracts variables and performance criteria relevant to service robotics applications. Future work on further integration based on neurobiological grounding is discussed as well as means by which the exemplar scenario may be scaled up to more realistic service robotics based scenarios.

The role of arousal in two-resource problem tasks for humanoid service robots

Konferensbidrag (refereegranskat)abstract
- A computational architecture of emotion is presented which grounds a component of an appraisal cognitive model into the homeostatic processes of a humanoid robot. The focus of the present work entails a `grounding' of the arousal component of the Pleasure Arousal Dominance emotion space into the electrical energy processes of an iCub robot. Key variables and performance criteria for robotic energy autonomous behavior in interaction with human are discussed. We show that our bio-inspired affective architecture offers viable basic cycles in exemplar “two-resource problem” testbed scenarios for a real iCub robot. The expression of the robot's emotional state and its role for the efficient interaction in the proposed two-resource problem task is discussed and experimental designs are presented.
