Book Synopsis Visual Perception for Humanoid Robots by : David Israel González Aguirre
Download or read book Visual Perception for Humanoid Robots written by David Israel González Aguirre and published by . This book was released on 2019 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of model-based environmental visual perception for humanoid robots. The visual perception of a humanoid robot creates a bidirectional bridge connecting sensor signals with internal representations of environmental objects. The objective of such perception systems is to answer two fundamental questions: What & where is it? To answer these questions using a sensor-to-representation bridge, coordinated processes are conducted to extract and exploit cues matching robot's mental representations to physical entities. These include sensor & actuator modeling, calibration, filtering, and feature extraction for state estimation. This book discusses the following topics in depth: • Active Sensing: Robust probabilistic methods for optimal, high dynamic range image acquisition are suitable for use with inexpensive cameras. This enables ideal sensing in arbitrary environmental conditions encountered in human-centric spaces. The book quantitatively shows the importance of equipping robots with dependable visual sensing. • Feature Extraction & Recognition: Parameter-free, edge extraction methods based on structural graphs enable the representation of geometric primitives effectively and efficiently. This is done by eccentricity segmentation providing excellent recognition even on noisy & low-resolution images. Stereoscopic vision, Euclidean metric and graph-shape descriptors are shown to be powerful mechanisms for difficult recognition tasks. • Global Self-Localization & Depth Uncertainty Learning: Simultaneous feature matching for global localization and 6D self-pose estimation are addressed by a novel geometric and probabilistic concept using intersection of Gaussian spheres. The path from intuition to the closed-form optimal solution determining the robot location is described, including a supervised learning method for uncertainty depth modeling based on extensive ground-truth training data from a motion capture system. The methods and experiments are presented in self-contained chapters with comparisons and the state of the art. The algorithms were implemented and empirically evaluated on two humanoid robots: ARMAR III-A & B. The excellent robustness, performance and derived results received an award at the IEEE conference on humanoid robots and the contributions have been utilized for numerous visual manipulation tasks with demonstration at distinguished venues such as ICRA, CeBIT, IAS, and Automatica.
Book Synopsis Developmental Approach of Perception for a Humanoid Robot by : Natalia Lyubova
Download or read book Developmental Approach of Perception for a Humanoid Robot written by Natalia Lyubova and published by . This book was released on 2013 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les robots de service ou d'assistance doivent évoluer dans un environnent humain en constant changement, souvent imprévisible. Ils doivent donc être capables de s'adapter à ces changements, idéalement de manière autonome, afin de ne pas dépendre de la présence constante d'une supervision. Une telle adaptation en environnements non structurés nécessite notamment une détection et un apprentissage continu des nouveaux objets présents, que l'on peut imaginer inspirés des enfants, basés sur l'interaction avec leur parents et la manipulation motivée par la curiosité. Notre travail vise donc à concevoir une approche développementale permettant à un robot humanoïde de percevoir son environnement. Nous nous inspirons à la fois de la perception humaine en termes de fonctionnalités et du développements cognitifs observé chez les infants. Nous proposons une approche qui permet à un robot humanoïde d'ex- plorer son environnement de manière progressive, comme un enfant, grâce à des interactions physiques et sociales. Suivant les principes de la robotique développementale, nous nous concentrons sur l'apprentissage progressif, continu et autonome qui ne nécessite pas de connaissances a priori des objets. Notre système de perception débute par la segmentation de l'espace visuel en proto-objets, qui serviront d'unités d'attention. Chaque proto-objet est représenté par des caractéristiques bas-niveaux (la couleur et la texture) et sont eux-mêmes intégrés au sein de caractéristiques de plus haut niveau pour ensuite former un modèle multi-vues. Cet apprentissage s'effectue de manière incrémentale et chaque proto-objet est associé à une ou plusieurs entités physiques distinctes. Les entités physiques sont ensuite classés en trois catégories : parties du robot, parties des humains et objets. La caractérisation est basée sur l'analyse de mouvements des entités physiques provenant de la vision ainsi que sur l'information mutuelle entre la vison et proprioception. Une fois que le robot est capable de catégoriser les entités, il se concentre sur l'interaction active avec les objets permettant ainsi d'acquérir de nouvelles informations sur leur apparence qui sont intégrés dans leurs modèles de représentation. Ainsi, l'interaction améliore les connaissances sur les objets et augmente la quantité d'information dans leurs modèles. Notre système de perception actif est évalué avec le robot humanoïde iCub en utilisant une base expérimentale de 20 objets. Le robot apprend par interaction avec un partenaire humain ainsi que par ses propres actions sur les objets. Notre système est capable de créer de manière non supervisée des modèles cohérents des différentes entités et d'améliorer les modèles des objets par apprentissage interactif et au final de reconnaître des objets avec 88.5% de réussite.

Book Synopsis Culture and Human-Robot Interaction in Militarized Spaces by : Dr Julie Carpenter
Download or read book Culture and Human-Robot Interaction in Militarized Spaces written by Dr Julie Carpenter and published by Ashgate Publishing, Ltd.. This book was released on 2016-01-28 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explosive Ordnance Disposal (EOD) personnel are some of the most highly trained people in the military, with a job description that spans defusing unexploded ordnance to protecting VIP’s and state dignitaries. EOD are also one of the first military groups to work with robots every day. These robots have become an increasingly important tool in EOD work, enabling people to work at safer distances in many dangerous situations. Based on exploratory research investigating interactions between EOD personnel and the robots they use, this study richly describes the nuances of these reciprocal influences, especially those related to operator emotion associated with the robots. In particular, this book examines the activities, processes and contexts that influence or constrain everyday EOD human-robot interactions, what human factors are shaping the (robotic) technology and how people and culture are being changed by using it. The findings from this research have implications for future personnel training, and the refinement of robot design considerations for many fields that rely on critical small group communication and decision-making skills.

Book Synopsis Quantum Communications and Cryptography by : Alexander V. Sergienko
Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.
