Abstract

Purpose

This paper aims to propose a novel system design and control algorithm of lower limb exoskeleton, which provides walking assistance and load sharing for the wearer.

Design/methodology/approach

In this paper, the valve-controlled asymmetrical hydraulic cylinder is selected for driving the hip and knee joint of exoskeleton. Pressure shoe is developed that purpose on detecting changes in plantar force, and a fuzzy recognition algorithm using plantar pressure is proposed. Dynamic model of the exoskeleton is established, and the sliding mode control is developed to implement the position tracking of exoskeleton. A series of prototype experiments including benchtop test, full assistance, partial assistance and loaded walking experiments are set up to verify the tracking performance and power-assisted effect of the proposed exoskeleton.

Findings

The control performance of PID control and sliding mode control are compared. The experimental data shows the tracking trajectories and tracking errors of sliding mode control and demonstrate its good robustness to nonlinearities. sEMG of the gastrocnemius muscle tends to be significantly weakened during assisted walking.

Originality/value

In this paper, a structure that the knee joint and hip joint driven by the valve-controlled asymmetrical cylinder is used to provide walking assistance for the wearer. The sliding mode control is proposed to deal with the nonlinearities during joint rotation and fluids. It shows great robustness and frequency adaptability through experiments under different motion frequencies and assistance modes. The design and control method of exoskeleton is a good attempt, which takes positive impacts on the productivity or quality of the life of wearers.

Abstract

Purpose

This study discusses the tracking trajectory issue of the exoskeleton under the bounded disturbance and designs an useful tracking trajectory control method to solve it. By using the proposed control method, the tracking error can be successfully convergence to the assigned boundary. Meanwhile, the chattering effect caused by the actuators is already reduced, and the tracking performance of the pneumatic artificial muscles (PAMs) elbow exoskeleton is improved effectively.

Design/methodology/approach

A prescribed performance sliding mode control method was developed in this study to fulfill the joint position tracking trajectory task on the elbow exoskeleton driven by two PAMs. In terms of the control structure, a dynamic model was built by conforming to the adaptive law to compensate for the time variety and uncertainty exhibited by the system. Subsequently, a super-twisting algorithm-based second-order sliding mode control method was subjected to the exoskeleton under the boundedness of external disturbance. Moreover, the prescribed performance control method exhibits a smooth prescribed function with an error transformation function to ensure the tracking error can be finally convergent to the pre-designed requirement.

Findings

From the theoretical perspective, the stability of the control method was verified through Lyapunov synthesis. On that basis, the tracking performance of the proposed control method was confirmed through the simulation and the manikin model experiment.

Originality/value

As revealed by the results of this study, the proposed control method sufficiently applies to the PAMs elbow exoskeleton for tracking trajectory, which means it has potential application in the actual robot-assisted passive rehabilitation tasks.

Abstract

Purpose

This study intends to analyze the trend of walkability research over two years (2021–2022) in several aspects, including the research problem, gap and aim underlying walkability issues, research setting, the scale of analysis, the type of data, the data collection tool, the analysis method and contribution.

Design/methodology/approach

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) is employed to conduct a systematic literature review from three leading databases including Web of Science (WoS), Scopus and Sage.

Findings

From the review, it can be concluded that the research focuses on two aspects, namely, the built environment and people. The studies in this field are conducted at different scales of the built environment, from macroscale to microscale, including region, city, neighborhood and street-level studies that are conducted around the world including Asia, Europe and America which receive high attention from researchers. Meanwhile, the study of walkability in Australia and Africa gains less attention. It is revealed that there are four factors of walkability including land use and accessibility for macroscale which cover region, city and neighborhood, while street network and pedestrian infrastructure and facility are mainly analyzed for street-level. Most of the studies widely utilize a quantitative approach for analyzing physical walkability factors in a measurement-based approach by using certain tools/software, and a perception-based approach by using questionnaires.

Research limitations/implications

The findings can assist to keep up with the rapid pace of scientific publications and help accelerate the understanding of particular ideas in the field of walkability for the planning and design practice and policy that can be used by researchers/academia, urban designers, urban planners, architects, engineers and policymakers. Also, this study hopefully could assist further research direction for the future and could add value to a more advanced way of understanding the research on walkability.

Originality/value

This research provides a robust framework for walkability trend analysis and a comprehensive understanding of the main ideas from the existing research on walkability worldwide.

Abstract

Purpose

This paper studies the role of heritage walks and tours in promoting inclusive education. It assesses if these walks are an effective method of exhibiting culture and facilitating inclusive heritage learning. The purpose of this paper is to attempt to establish that walks can play an imperative role in creating greater sensitivity towards heritage and conservation.

Design/methodology/approach

The study uses a case study approach using mixed methods. Participants for qualitative interviews were chosen using purposive sampling and six interview schedules were sent to walk leaders. Walk participant data were collected through participant observation and standardised survey with randomly selected participants of the case walks. Surveys were sent to participants electronically.

Findings

Heritage walks play a crucial role in not only imparting knowledge about history and heritage but also as a tool for learning other crucial skills, competencies, values, attitudes, etc. This paper attempts to highlight that walks are an effective and inclusive way to shed light on the alternative and forgotten stories. As an educational tool these walks can not only encourage the development of historical knowledge and appreciation but also assist in the development of competency to “de-construct” mainstream “grand narratives”, questioning and learning about the forgotten.

Research limitations/implications

This paper has limited itself to the study of select cases in New Delhi. Since the study has followed a case study design, it does not produce a largely generalizable result, but rather examines and understands the dynamics of particular walks and produces insights that may well be applicable in other contexts. Whilst this paper makes an attempt to understand the changes in perception and attitudes, it does not study behavioural changes.

Social implications

In the long run, walks allow for meaningful citizen engagement with tangible heritage such as monuments as well as intangible heritage such as practices and festivals. This allows for appreciation for the value of heritage resources and leads to a demand for better conservation and preservation from the authorities. In a few cases, local citizens themselves lead heritage management and development activities in a bid to promote their local culture. This paper has shown that heritage walks can be helpful tools in giving “forgotten” voices and stories recognition in contemporary society.

Originality/value

As heritage walks have recently gained popularity, there has been very limited research in the field especially linking heritage walks to heritage education. This is especially true for India. Even a city like New Delhi, which boasts of a robust heritage and is one of the tourism hubs of the country, heritage walks have been a very recent phenomenon. This research aims to address this lacuna in academic research and contribute meaningfully to the field of heritage education and conservation by studying how heritage walks support and promote inclusive heritage education.

Abstract

Peripheral arterial disease (PAD) is an occlusive atherosclerotic disease that affects blood vessels and reduces blood flow in the lower limbs. It is estimated that around 200 million people worldwide suffered from it, with a significant number of older people affected. Walking is one of the first-line therapeutic measures for intermittent claudication (IC) in patients with PAD. Supervised Exercise Therapy (SET) programs effectively increase walking distances, however, remain an underutilized tool because they are not readily available in most clinical centres, are extremely expensive, and patient participation is low mainly due to socioeconomic constraints. Home-based Exercise Therapy (HBET) programs are an effective and low-cost alternative to improve both the functional capacity and quality of life (QoL) of patients with IC, as they are performed in the patient’s area of residence and not in the hospital. The WalkingPad program conciliated a smartphone app – the WalkingPad app – with behaviour change intervention to increase walking distances and decrease walking impairment as well to improve QoL at 6 months.
