Actuators for human-interactive robot systems require transparency and guaranteed safety. An actuation system is called transparent when it is able to generate an actuation force as desired without any actuator dynamics. The requirements for the transparent actuation include high precision and large frequency bandwidth in actuation force generation, zero mechanical impedance and so on. In this paper, a compact rotary series elastic actuator (cRSEA) is designed considering the actuation transparency and the mechanical safety.

The mechanical parameters of a cRSEA are optimally selected for the controllability, the input and output torque transmissibility and the mechanical impedance by simulation study. A mechanical clutch that automatically disengages the transmission is devised such that the human is mechanically protected from an excessive actuation torque due to any possible controller malfunction or any external impact from a collision. The proposed cRSEA with a mechanical clutch is applied to develop a wearable robot for incomplete paraplegic patients. To verify torque tracking performance and disengagement of the mechanical clutch, experiments were conducted.

As the effects of the gear ratio, N1, on the four control performance indexes are conflicting, it should be carefully selected such that the controllability and the output torque transmissibility are maximized, while the disturbance torque transmissibility and the mechanical impedance are minimized. When the four control performance indexes were equally weighted, N1 was selected as 30. Experimental results showed that the designed cRSEA provided good control performances and the mechanical clutch worked properly.

It is important to design the actuator so as to maximize the control performance in accordance with its purpose. This paper presents the design guidelines for the SEA by introducing four control performance indexes and analyzing how the performance indexes vary according to the change of design parameter. From the viewpoint of practicality, a mechanical clutch design method that prevents excessive torque from being transmitted to the wearer and an analysis to solve the locking phenomenon when using a worm gear are presented, and a design method of SEA satisfying both control performance and practicality is presented.

Wesley Snipes has had an extensive career on the big screen starting out as part of the New Black Cinema movement in the 1990s working with Spike Lee and Mario Van Peebles. His roles have been incredibly varied covering drama, comedy, action, thriller, horror and Science Fiction: he has played everything from jazz saxophonist to paraplegic and drag queen to vampire, as well as recently appearing as character actor D'Urville Martin in Eddie Murphy's critically acclaimed Dolemite Is My Name. However, despite his versatility as an actor and his popularity in action films such as Demolition Man and the Blade Trilogy, Snipes has been, surprisingly, the subject of minimal analysis unlike, for example Schwarzenegger and Stallone. Unfortunately, he has also fallen foul of the direct to video curse from around 2005 as well as being sentenced to three years in prison for tax evasion. However, this should not negate Snipes' contribution to cinema, especially in the genre of action. Snipes can be a commanding presence given the right script and direction – as an expert martial artist he is lithe and agile; he has strong facial features and a powerful voice, plus the ability to deliver the wisecracking humour which often goes hand-in-hand with action performances. The aim of this chapter, then, is to focus on Snipes as an action star and, more specifically, his significance as a black action star, examining several key films which have helped to develop his onscreen persona and performance style.

The following paper is a “Q&A interview” conducted by Joanne Pransky of Industrial Robot Journal as a method to impart the combined technological, business and personal experience of a prominent, robotic industry PhD-turned innovator and entrepreneur regarding his pioneering efforts. The paper aims to discuss these issues.

The interviewee is Dr Homayoon Kazerooni, Professor of Mechanical Engineering at the University of California (UC) Berkeley, pioneer and leading entrepreneur of robotic exoskeletons. He is a foremost expert in robotics, control sciences, exoskeletons, bioengineering and mechatronics design. Kazerooni shares in this interview details on his second start-up, US Bionics DBA suitX.

Kazerooni received his MS and PhD in Mechanical Engineering from the Massachusetts Institute of Technology (MIT). He has been a Professor at UC Berkeley for over 30 years. He also serves as the Director of the Berkeley Robotics and Human Engineering Laboratory “KAZ LAB.” The lab’s early research focused on enhancing human upper extremity strength, and Kazerooni led his team to successfully develop a new class of intelligent assist devices that are currently marketed worldwide and used by manual laborers in distribution centers and factories worldwide. Dr Kazerooni’s later work focused on the control of human–machine systems specific to human lower extremities. After developing BLEEX, ExoHiker and ExoClimber – three load-carrying exoskeletons – his team at Berkeley created Human Universal Load Carrier. It was the first energetically autonomous, orthotic, lower extremity exoskeleton that allowed its user to carry 100-pound weights in various terrains for an extended period, without becoming physically overwhelmed. The technology was initially licensed to Ekso Bionics and then Lockheed Martin. Kazerooni and his team also developed lower-extremity technology to aid persons who have experienced a stroke, spinal cord injuries or have health conditions that obligate them to use a wheelchair.

In 2005, Kazerooni founded Ekso Bionics, the very first exoskeleton company in America, which went on to become a publicly owned company in 2014. Ekso, currently marketed by Ekso Bionics, was designed jointly between Ekso Bionics and Berkeley for paraplegics and those with mobility disorders to stand and walk with little physical exertion. In 2011, Austin Whitney, a Berkeley student suffering from lower limb paralysis, walked for commencement in one of Kazerooni’s exoskeletons, “The Austin Exoskeleton Project,” named in honor of Whitney. Kazerooni went on in 2011, to found US Bionics, DBA suitX, a venture capital, industry and government-funded robotics exoskeleton company. suitX’s core technology is focused on the design and manufacturing of affordable industrial and medical exoskeletons to improve the lives of workers and people with gait impairment. suitX has received investment from Wistron (Taiwan), been awarded several US government awards and won two Saint-Gobain NOVA Innovation Awards. suitX has also won the US$1m top prize in the “UAE AI and Robotics for Good” Competition. Its novel health-care exoskeleton Phoenix has recently received FDA approval. Kazerooni has won numerous awards including Discover magazine’s Technological Innovation Award, the McKnight-Land Grant Professorship and has been a recipient of the outstanding ASME Investigator Award. His research was recognized as the most innovative technology of the year in New York Times Magazine. He has served in a variety of leadership roles in the mechanical engineering community and served as editor of two journals: ASME Journal of Dynamics Systems and Control and IEEE Transaction on Mechatronics. Kazerooni has published more than 200 articles to date, delivered over 130 plenary lectures internationally and is the inventors of over 100 patents.

The purpose of this paper is to explore the multi-level mechanisms of institutional formation and change and, in particular, how this occurs through the interplay of multi-level mechanisms? This is answered with a processual analysis of the International Paralympic Committee which is the international governing body of sports for people with an impairment.

This study uses a case-study approach based upon archival records, collected in relevant national and international sport organizations. More than 2,700 pages of archives were gathered, some of them being accessible to researchers for the first time. Embargo was also successfully lifted on recent and sensitive documents.

This study highlights multi-level mechanisms involved in institutional change processes triggered by a shifting institutional logic at the organizational field level. This paper also shows how field logic shifted at the moment of alignment between the societal, field and organizational levels. Moreover, it underlines how societal discourses influenced processes of institutional change by shaping the range of organizational actions available at the organizational and field levels.

This paper proposes a rare account of institutional change processes in which interplay between the societal, field, and organizational levels is analyzed. Furthermore, this paper provides a longitudinal investigation of an under-researched empirical setting, the Paralympic movement. Finally, this study integrates insights from the disability studies’ research field, which significantly deepens this analysis.

The concept expressed by the phrase ‘accessible tourism’ reflects a case of which there is a lot of talk through the means of communication and through which it is possible to promote a theme that must be at the heart of individual subjects, or the accessibility to the use of public transport and mobility, catering and leisure, so it is a concept that aims to encourage a connection between the various services to make them truly usable for all those people who have diverse needs: children, the elderly, mothers with strollers, people with disabilities who move in a wheelchair or who have difficulty walking, people who have limitations in the upper and/or lower limbs, people who do not see and/or do not hear, who have allergies or intolerances to environments or food. Tourism is, therefore, inclusive. In any case, the word accessibility is configured as an ideal towards which, in order to achieve equality of rights and duties, an equality allows the individual to participate in social life as a whole. Therefore, we must not limit the aforementioned concept, only in relation to tourism, but we must consider it in a broader sense, for example, the World Health Organization (WHO) defines it as the ‘possibility of accessing the benefits that everyday life can offer, without encountering architectural barriers’.

The tourism sector, first of all, is that sector that has felt the need to pay attention to this issue. In particular, the tourism sector sees on the one hand the tourist offer that is proposed by the accommodation businesses, and on the other, the demand characterized by the need to satisfy ever more varied needs.

Accessibility, from this point of view, is configured as the most important feature that the tourist offer must have because it allows to bring the demand closer to the offer, managing to satisfy all the needs inherent in the characteristics of the various subjects. The characteristics that the tourism sector must possess in order to be able to speak of accessibility are as follows: firstly, this important word contains many meanings. It is customary to consider the following aspects in order to take into consideration the concept of accessibility: architectural barriers, sources of danger and sources of fatigue. The presence of these elements makes accessible tourism incomplete because it cannot satisfy the users of these services.

Very often, in fact, institutions and ministries have framed within the concept of accessibility all those people in wheelchairs or those paraplegic subjects, as well as all those people with reduced motor skills.

It is therefore necessary to be able to frame the users of accessible tourism and in this wake to propose accessible transport, viable accommodation facilities, but also proposals and programs with itineraries that are once again accessible. In any case, the audience of recipients of accessible tourism cannot be framed in a certain and definitive way, since people with reduced mobility or to whom the offer of accessible structures and services is extended may concern not only subjects with different types of disabilities such as problems of motor, sensory, cognitive or health type but also people who have food-type difficulties such as, for example, people with food allergies or intolerances.

Tourist accessibility is, however, a problem that occurs in every situation of everyday life. The solution to solve the problem of accessibility must be implemented consistently and gradually: a shared awareness of the creation of a built, urban and building space is needed, as well as consultation at all legislative levels in order to reach a clear and efficient legislation.

Making every guest feel like an active protagonist of their tourist experience must be the goal for all those who care about the well-being and satisfaction of all their guests.

BeingBeing able to offer accessible hospitality is an indicator of not only efficiency and professionalism but also great attention to the quality of the service, also in the face of specific requests from guests with disabilities. It means being able to be highly competitive and enjoy an advantage that allows you to stand out.

Tourism companies can insert important ethical values within their strategic business vision by investing in a social business.

What are the advantages that accessible hospitality can offer to a hotel? The expansion of the market through: 1) the increase in seasonality; 2) the increase in turnover; and 3) customer loyalty.

To achieve these advantages, however, it is necessary to adopt strategies.

Training is the most powerful tool through which those who govern the company can transfer the philosophy and know-how of industry experts on accessible hospitality directly to their collaborators, both in positions of responsibility and coordination and merely executive personnel – skills necessary to set up an organized structure that aims at the best quality of its services and therefore at the satisfaction of its guests.

In the 1970s, the United States Congress enacted two statutes that have had dramatic and far‐reaching effects on the education of handicapped children by public schools. These two laws, Section 504 of the Rehabilitation Act of 1973 and the Education For All Handicapped Children Act of 1975 (known as Public Law 94–142), have required local public school agencies to provide new eductional programs for thousands of handicapped children not previously served by the public schools. Counselors, principals, and teachers were quickly informed of the law's requirements and willingly began the task of main‐streaming and assimilating these children into various curricula. Their physical needs were attended to rapidly; their societal and emotional needs, unfortunately, lagged behind. Within the past seven years, there has been an increase in books, articles, and films specifically addressed to counseling the handicapped. Unlike past literature which focused only on the vocational aspect of rehabilitation counseling, current writing emphasizes personal counseling meant to assist a disabled child to participate fully in the problems and joys of daily living.

Lower-limb exoskeleton systems enable people with spinal cord injury to regain some degree of locomotion ability, as the expected motion curve needs to adapt with changing scenarios, i.e. stair heights, distance to the stairs. The authors’ approach enables exoskeleton systems to adapt to different scenarios in stair ascent task safely.

In this paper, the authors learn the locomotion from predefined trajectories and walk upstairs by re-planning the trajectories according to external forces posed on exoskeleton systems. Moreover, instead of using complex sensors as inputs for re-planning in real-time, the approach can obtain forces acting on exoskeleton through dynamic model of human-exoskeleton system learned by an online machine learning approach without accurate parameters.

The proposed approach is validated in both simulation environment and a real walking assistance exoskeleton system. Experimental results prove that the proposed approach achieves better performance than the traditional predefined gait approach.

First, the approach obtain the external forces by a learned dynamic model of human-exoskeleton system, which reduces the cost of exoskeletons and avoids the heavy task of translating sensor input into actuator output. Second, the approach enables exoskeleton accomplish stair ascent task safely in different scenarios.

More than 100 engineers and researchers from industry and from government and academic laboratories met in Pittsburgh, Pennsylvania, in September at the Fourth World Conference on Robotics Research, sponsored by Robotics International of the Society of Manufacturing Engineers.

This chapter focusses on entrepreneurship and policies of public services in England, specifically leisure centre provision in the UK during the late twentieth century. The central role played by local authorities in sport provision was complimented by an increasing cadre of leisure sector professionals and with increasing architectural interest in the provision of leisure. The institutional context was framed by the Sports Development Council (SDC) after 1965 together with the broader action of local authorities who aimed to provide their ratepayers with access to improved sport and leisure services. The resulting leisure centres were perhaps a way to signal the prestige of local authorities but were expensive investments. The capability of local authorities was boosted by the local government reforms of the 1970s, which merged districts, pooling their resources. The possibility of support from private capital and after 1973 from the European Economic Community (EEC) also provided new opportunities for the organizational form. Eventually, there was a shift in emphasis from the provision of organized sport to that of more individualized and commercialized “leisure” as a product. Whether or not this achieved the long-term aims of central government, to improve access to sport and to tackle urban challenges, remains questionable. However, the story of leisure provision in the UK remains one of remarkable public sector entrepreneurship within an institutional context.
