Climbing and Walking Robots

With the advancement of technology, new exciting approaches enable us to render mobile robotic systems more versatile, robust and cost-efficient. Some researchers combine climbing and walking techniques with a modular approach, a reconfigurable approach, or a swarm approach to realize novel prototypes as flexible mobile robotic platforms featuring all necessary locomotion capabilities. The purpose of this book is to provide an overview of the latest wide-range achievements in climbing and walking robotic technology to researchers, scientists, and engineers throughout the world. Different aspects including control simulation, locomotion realization, methodology, and system integration are presented from the scientific and from the technical point of view. This book consists of two main parts, one dealing with walking robots, the second with climbing robots. The content is also grouped by theoretical research and applicative realization. Every chapter offers a considerable amount of interesting and useful information

Ultrasonic Tethering to Enable Side-by-Side Following for Powered Wheelchairs

In social situations, people who use a powered wheelchair must divide their attention between navigating the chair and conversing with people. These conversations could lead to increased mental stress when navigating and distraction from maneuvering the chair. As a solution that maintains a good conversation distance between the wheelchair and the accompanying person (Social Following), a wheelchair control system was developed to provide automated side-by-side following by wirelessly connecting the wheelchair to the person. Two ultrasonic range sensors and three piezoelectric ultrasonic transducers were used to identify the accompanying person and determine their position and heading. Identification involved an ultrasonic beacon worn on the person’s side, at hip level, and receivers on the wheelchair. A drive control algorithm maintained a constant conversation distance along the person’s trajectory. A plug-and-play prototype was developed and connected to a Permobil F5 Corpus wheelchair with a modified Eightfold Technologies SmartChair Remote. Results demonstrated that the system can navigate a wheelchair based on the accompanying person’s trajectory, which is advantageous for users who require hands-free wheelchair control during social activities

État des connaissances sur les fauteuils roulants motorisés intelligents (FRMIs) et recommandations pour la poursuite de leur développement : un examen de la portée

Contexte : La participation sociale d’utilisateurs de fauteuils roulants peut être affectée par certains facteurs, tels que l’accessibilité et les caractéristiques individuelles de ces derniers, pouvant limiter leur pleine implication dans la réalisation des activités signifiantes de la vie quotidienne. Afin d’améliorer leur mobilité, différents prototypes de fauteuils roulants motorisés intelligents (FRMIs) sont en développement, à l’intention de personnes présentant des déficiences physiques, cognitives ou sensorielles, et qui sont dans l’incapacité d’utiliser un fauteuil roulant motorisé (FRM). Le but visé est de leur procurer davantage d’autonomie dans leurs déplacements, et tenter ainsi de répondre à leurs besoins en termes de mobilité et de participation sociale. Objectif : Explorer la littérature portant sur le développement de FRMIs afin de comprendre dans quelle mesure les prototypes existants répondent aux besoins réels des utilisateurs, d’identifier les limites des études, et de faire des recommandations pour mieux orienter le développement continu des FRMIs. Méthodologie : Un examen de la portée a été réalisé suivant les six étapes proposées par Arskeys et O’Malley (2005), puis bonifiées par Levac et al. (2010). Les études publiées en anglais ou en français, jusqu’à septembre 2020, ont été consultées. Résultats : Au total, 41 études ont été retenues pour l’analyse. Les résultats suggèrent que les différentes technologies intégrées aux FRMIs pourraient contribuer à répondre à certains besoins d’utilisateurs présentant différentes incapacités, contribuer à améliorer leur mobilité, procurer de l’autonomie et favoriser leur participation sociale. Par ailleurs, des résultats complémentaires ont permis d’identifier : (a) d’autres technologies, pouvant favoriser davantage le sentiment d’autonomie et de confort aux utilisateurs, et (b) d’autres usages possibles du FRMI en clinique. Une limite importante identifiée est l’absence d’études expérimentales pouvant permettre d’évaluer l’efficacité du FRMI. Le point de vue des proches-aidants est également peu rapporté dans la littérature. Conclusion : Des études futures seraient à envisager en vue d’améliorer les prototypes de FRMIs existants.Background: The level of social participation among wheelchair users can be affected by factors such as accessibility, as well as their individual clinical profile, which can limit their full involvement in meaningful activities of daily living. To meet their needs in terms of mobility and social participation, different prototypes of intelligent powered wheelchairs (IPW) are being developed, in order to improve the mobility of people with physical, cognitive or sensorial impairments, who have difficulties using standard powered wheelchairs. Objective: The aim of this study was to map the existing literature on the nature of studies carried out on IPWs to better understand how the existing IPWs meet the needs of powered wheelchair users, and to better guide the ongoing development of IPWs. Methods: A scoping review was conducted in accordance with the six stages of Arskeys and O’Malley’s (2005) framework which was later enhanced by Levac et al. (2010). All studies available until September 2020, written in English or in French, were included. Results: A total of 41 studies were included in the scoping review. The results suggest that the various technologies integrated into IPWs could meet some of the needs of powered wheelchair users (PWu), could help improve mobility, provide independence, and promote social participation of some PWu. Moreover, additional results were identified: (a) other technologies, that could provide more independence and comfort to users, and (b) other clinical uses of IPW. An important limitation of the literature is the lack of experimental studies that could help assessing the efficiency of IPW. The point of view of caregivers is also less reported in the literature. Conclusion: Further studies should be considered to improve the functioning of the existing prototypes of IPW

Thinking Bodies and Sensational Minds: Affect and Embodiment in Contemporary Art

The human subject is profoundly interdependent, in relation to other people and to the surrounding environment, both “natural” and technological. Western dualistic thinking creates bounded and oppositional categories and generates a conception of human subjects as autonomous, self-sufficient beings that are transparent to themselves and in control of self, other, and world. This contributes to the ongoing inequalities in society and supports normative hegemony. This dissertation argues that it is imperative to insist on the intersubjective, permeable, and contingent qualities of existence. While this project is preceded by a great deal of theoretical criticism of Western metaphysical dualism, we must still continually work to break down the binaries of mind and body, self and other, rational and emotional, culture and nature. We need not just to critique the binaries but to generate new ways of thinking. I propose that art can act as a catalyst for thinking the new. Art can queer the boundaries. It is impossible to separate out the mind from the sensual body in the production or reception of art. Art demonstrates how the sensual and affected/affecting body is integral to the thinking subject, not an impurity or distraction that needs to be controlled

Analysis of the backpack loading efects on the human gait

Gait is a simple activity of daily life and one of the main abilities of the human being. Often during leisure, labour and sports activities, loads are carried over (e.g. backpack) during gait. These circumstantial loads can generate instability and increase biomechanicalstress over the human tissues and systems, especially on the locomotor, balance and postural regulation systems. According to Wearing (2006), subjects that carry a transitory or intermittent load will be able to find relatively efficient solutions to compensate its effects.info:eu-repo/semantics/publishedVersio
