Abstract

Presents an overview of how satellite‐based positioning techniques could be used to develop novel navigational methods for use on mobile robotic platforms. Details are given of the major terrestrial techniques, both internal and external to the robot, which have been traditionally used to meet positioning requirements. A descriptive summary of the global positioning system of navigation satellites (GPS) is followed by an introduction to Galileo, the European project on the development of a comparable system. A small number of examples, either near to market or in use now, are used to illustrate the use of robotic systems that use GPS as a source of 3D absolute position information, but also velocity, attitude and time. Concludes that GPS is likely to become the universal positioning standard for outdoor applications, with future augmentations and developments enhancing the reliability, integrity and accuracy of the system. Nevertheless, in most cases it will still be necessary to use GPS in combination with alternative positioning sensors.

Abstract

Purpose

This study aims to find a feasible precise navigation model for the planed Lunar rover. Autonomous navigation is one of the most important missions in the Chinese Lunar exploration project. Machine vision is expected to be a promising option for this mission because of the dramatic development of an image processing technique. However, existing attempts are often subject to low accuracy and errors accumulation.

Design/methodology/approach

In this paper, a novel autonomous navigation model was developed, based on the rigid geometric and photogrammetric theory, including stereo perception, relative positioning and absolute adjustment. The first step was planned to detect accurate three-dimensional (3D) surroundings around the rover by matching stereo-paired images; the second was used to decide the local location and orientation changes of the rover by matching adjacent images; and the third was adopted to find the rover’s location in the whole scene by matching ground image with satellite image. Among them, the SURF algorithm that had been commonly believed as the best algorithm for matching images was adopted to find matched images.

Findings

Experiments indicated that the accurate 3D scene, relative positioning and absolute adjustment were easily generated and illustrated with the matching results. More importantly, the proposed algorithm is able to match images with great differences in illumination, scale and observation angle. All experiments and findings in this study proved that the proposed method could be an alternative navigation model for the planed Lunar rover.

Originality/value

With the matching results, an accurate 3D scene, relative positioning and absolute adjustment of rover can be easily generated. The whole test proves that the proposed method could be a feasible navigation model for the planed Lunar rover.

Abstract

Purpose

The purpose of this study is to provide an in-depth understanding about the indoor-orbital electrical inspection robot, which is useful for motivating the further investigation on the inspection of electrical equipment. Currently, electric energy has a strong correlation with the economic development of the country. Intelligent substations play an important role in the transmission and distribution of the electricity; the maintenance of the substation has attracted intensive attention due to the requirement of reliability and safety. The indoor-orbital electrical inspection robot has increasingly become the main tool to realize the unmanned. Hence, a systematic review is conducted systematically reviewing the current technical status of the indoor-orbital electrical inspection robot and discuss the existed problems.

Design/methodology/approach

In this paper, the most essential achievements in the field of indoor-orbital electrical inspection robots were reported to present the current status, and the mechanical structures and key inspective technologies were also discussed.

Findings

Four recommendations are provided from the analyzed review, which have made constructive comments on the overall structural design, functionality, intelligence and future development direction of the indoor-orbital electrical inspection robot, respectively.

Originality/value

To the best of the authors’ knowledge, this is the first systematic review study on indoor-orbital electrical inspection robots; it fills the theoretical gap and proffers design ideas and directions for the development of the indoor-orbital electrical inspection robot.

Abstract

Purpose

This study aims to explore the perceptions and reactions of men, who participate in a female-dominated online consumption space. It looked at the process of men, (re)negotiating their digital gendered identity on Pinterest.

Design/methodology/approach

A grounded theory-light approach was taken. Data were collected through 21 one-on-one semi-structured interviews with male Pinterest users. Subsequently, data were extensively coded and analyzed for the key themes and patterns.

Findings

Three core categories emerged, which speak to the ways men account for their practices on Pinterest as autonomous online agents. These categories were: awareness of Pinterest as a feminized digital space; limited sociality due to the solitary use of Pinterest (the exception being when collaborating with an intimate partner); and performed identities (k = 4) serving to justify the men’s activities on a female-dominated social networking site.

Research limitations/implications

The findings establish a firm theoretical basis for understanding male Pinterest users as autonomous online agents. However, reflective of this relatively small, exploratory qualitative project, the process-based interview questions did not render, particularly, long or rich narratives. Future qualitative research might endeavor to ask deeper, more open-ended questions.

Originality/value

This is an original study of men’s use of Pinterest. Research on the identity projects of men entering fields traditionally occupied by women and coded as feminine is established, there is a lack of understanding of how gender identity is (re)constructed digitally, especially on social media.

Abstract

Purpose

The purpose of this paper is to analyse and compare the impact of implementation of ISO 9001:2008 Standards perceived by Management Teams and Teachers in schools in four autonomous communities in Spain.

Design/methodology/approach

To assess this impact, the authors used an evaluation instrument made up of 93 items assessing seven major dimensions, whose reliability has been excellent for the full scale (Cronbach’s α = 0.987) and dimensions (α > 0.93). The authors conducted descriptive and differential analyses (ANOVA and t-test for independent samples) of the assessments by professional position (managers and teachers) and other variables (size and type of school, years of implantation, etc.). A factorial analysis of variance was conducted to analyse the interaction effect between these variables in each of the evaluated dimensions.

Findings

The most significant results show a high impact on the dimension management, medium on communication, learning process and external relations and low impact on climate, support and recognition and satisfaction. Likewise, the authors found that members of the Management Teams valued the impact that ISO 9001:2008 Standards have had on all dimensions at a higher level, except for external relations, where no significant differences between Teachers and Management Team members were found.

Practical implications

The study makes it possible to conclude that in general terms, the members of the Management Team of the schools perceive a higher impact of the implementation of ISO 9001:2008 Standards than teacher do in the different dimensions evaluated.

Originality/value

The specialised literature shows the lack of studies related to the impact that the implementation of quality management systems has on organisations. Specifically, this study provides conclusions to the scientific and professional community with objective evidence of the impact ISO 9001:2008 implementation has had on schools, through an indirect system of perceptions of the education community of the changes, which according to them had taken place as a result of implementation. Thus, this study contributes to the development of a new body of knowledge by evaluating this impact.

Abstract

Purpose

A literature review is presented in the subject of construction plant and equipment management (CPeM) to: delineate the subject; consider its development over recent years; and identify principal themes within it. The paper aims to close the gap in knowledge, by using these objectives as a mechanism to observe how research themes relate to primary CPeM functions, and to suggest future research direction.

Design/methodology/approach

A thematic review of CPeM academic literature (in the main, refereed journal papers published in English‐speaking countries over the last decade) is undertaken; the nature of identified themes is discussed, for instance, regarding why they might have evolved as they have; and based on the foregone, themes for future research in the field are proffered.

Findings

CPeM is found well established within the broader subject of construction management. Eight principal themes are identified, namely plant maintenance; downtime and productivity; optimisation; robotics and automation; health and safety; operators and competence; machine control; and “miscellaneous”.

Research limitations/implications

It is proffered that based on informational/technological advancements coupled with growing environmental/financial pressures, future CPeM research will strive to facilitate even greater plant reliability and safer modes of working. It is suggested that “optimum production methods” and “minimal resource consumption” will become inherent theme goals.

Originality/value

This is the first time that CPeM research has been consolidated and reviewed for publication in this manner.

Abstract

Purpose

The purpose of this paper is to explain how and why the initially ambitious reform of the Dutch water sector turned into a moderate pace of change. The explanations are based on institutional theory.

Design/methodology/approach

This paper is a case study at the organizational field level of the Dutch water sector.

Findings

In order to enhance efficiency and transparency, Dutch Central Government initially attempted to enforce top‐down radical changes, including the formation of integrated water chain companies. However, after discussions and reactions of the interested parties, the central government authorised a bottom‐up approach, giving discretional powers to the individual water organizations. This transition to a bottom‐up approach can mainly be explained by the limited pressure exerted by the central government to change and the powerful position of the relevant organizations within the water sector, as well as their ability to establish strong coalitions to avoid mandatory radical changes.

Research limitations/implications

The theoretical background is useful in analysing the change processes in other public sectors.

Practical implications

The Dutch way of consensus seeking might be threatened by its own inertia, and in the case of ineffectiveness, it could be replaced by a more top‐down and radical reform package.

Originality/value

Unravelling public sector reform into goals, means and approaches is useful, because although goals can remain the same during the change process, the means and approaches may be altered. Resistance to radical changes might stimulate convergent change options, such as reinforcement of the existing means of reform and may also decrease the embededdness and impermeability of the institutional fields.

Abstract

Purpose

The purpose of this study is to solve the key technical problems of the practical application of electric robots. The UHV multi-split transmission line power cable operation robot is an important equipment to ensure the reliable operation of high voltage lines and is a useful exploration to realize high-quality power transmission. As the robot system platform equipment mature and operation environment gradually become more complex, the double arm coordination motion control in extreme environment becomes one of the main bottleneck for its practical in power system.

Design/methodology/approach

This paper summarizes the key technologies related to power cable robots, and aims at key technical indicators such as operation reliability, operation efficiency and operation quality in the robot’s practical process. The dynamic evolution mechanism of the robot’s mechanical configuration, the multi-physics information fusion algorithm in extreme environments, the robot’s autonomous positioning and its error compensation control, the robot’s robust motion control in extreme environments and the dual-arm force-position hybrid coordination control and the dynamic distribution and elimination mechanism of internal forces in the closed chain between robots and operating objects, all the research methods and solutions of the key technologies are proposed, respectively.

Findings

Finally, a new control architecture for power cable robots in the background of the Ubiquitous Power Internet of Things is proposed so as to manage the operation and maintenance of electric power systems. The above key technologies are a new exploration of the operation and maintenance management of EHV (Extra High Voltage) multi-split transmission lines which have laid a solid theoretical foundation for the power cable robot.

Originality/value

High voltage transmission line is the main channel of power transmission. It is an important means to improve the integration of operation and maintenance management of power system to use robot instead of manual inspection and maintenance of power line, in the promotion and application of electric robot. The authors pay attention to the practicability, and the breakthrough of key technologies of robot is the premise of the practicability of robot. In this paper, the robot operation and control in multi-task and complex scenes are studied. The research and implementation of the main key technologies, such as the dynamic evolution mechanism of robot configuration, the coupling and fusion law of multi physical fields in the extreme electric power environment, the autonomous positioning control of manipulator, the robust control of robot in the super electromagnetic field environment and the cooperative operation control of multi manipulator, are discussed.

Abstract

Purpose

The purpose of this paper is to verify the correctness and feasibility of simultaneous localization and mapping (SLAM) algorithm based on red-green-blue depth (RGB-D) camera in high precision navigation and localization of celestial exploration rover.

Design/methodology/approach

First, a positioning algorithm based on depth camera is proposed. Second, the realization method is described from the five aspects of feature detection method, feature point matching, point cloud mapping, motion estimation and high precision optimization. Feature detection: taking the precision, real-time and motion basics as the comprehensive consideration, the ORB (oriented FAST and rotated BRIEF) features extraction method is adopted; feature point matching: solves the similarity measure of the feature descriptor vector and how to remove the mismatch point; point cloud mapping: the two-dimensional information on RGB and the depth information on D corresponding; motion estimation: the iterative closest point algorithm is used to solve point set registration; and high precision optimization: optimized by using the graph optimization method.

Findings

The proposed high-precision SLAM algorithm is very effective for solving high precision navigation and positioning of celestial exploration rover.

Research limitations/implications

In this paper, the simulation validation is based on an open source data set for testing; the physical verification is based on the existing unmanned vehicle platform to simulate the celestial exploration rover.

Practical implications

This paper presents a RGB-D camera-based navigation algorithm, which can be obtained by simulation experiment and physical verification. The real-time and accuracy of the algorithm are well behaved and have strong applicability, which can support the tests and experiments on hardware platform and have a better environmental adaptability.

Originality/value

The proposed SLAM algorithm can deal with the high precision navigation and positioning of celestial exploration rover effectively. Taking into account the current wide application prospect of computer vision, the method in this paper can provide a study foundation for the deep space probe.

Abstract

Purpose

Connecting autonomous drones to ground operations and services is a prerequisite for the adoption of scalable and sustainable drone services in the built environment. Despite the rapid advance in the field of autonomous drones, the development of ground infrastructure has received less attention. Contemporary airport design offers potential solutions for the infrastructure serving autonomous drone services. To that end, this paper aims to construct a framework for connecting air and ground operations for autonomous drone services. Furthermore, the paper defines the minimum facilities needed to support unmanned aerial vehicles for autonomous logistics and the collection of aerial data.

Design/methodology/approach

The paper reviews the state-of-the-art in airport design literature as the basis for analysing the guidelines of manned aviation applicable to the development of ground infrastructure for autonomous drone services. Socio-technical system analysis was used for identifying the service needs of drones.

Findings

The key findings are functional modularity based on the principles of airport design applies to micro-airports and modular service functions can be connected efficiently with an autonomous ground handling system in a sustainable manner addressing the concerns on maintenance, reliability and lifecycle.

Research limitations/implications

As the study was limited to the airport design literature findings, the evolution of solutions may provide features supporting deviating approaches. The role of autonomy and cloud-based service processes are quintessentially different from the conventional airport design and are likely to impact real-life solutions as the area of future research.

Practical implications

The findings of this study provided a framework for establishing the connection between the airside and the landside for the operations of autonomous aerial services. The lack of such framework and ground infrastructure has hindered the large-scale adoption and easy-to-use solutions for sustainable logistics and aerial data collection for decision-making in the built environment.

Social implications

The evolution of future autonomous aerial services should be accessible to all users, “democratising” the use of drones. The data collected by drones should comply with the privacy-preserving use of the data. The proposed ground infrastructure can contribute to offloading, storing and handling aerial data to support drone services’ acceptability.

Originality/value

To the best of the authors’ knowledge, the paper describes the first design framework for creating a design concept for a modular and autonomous micro-airport system for unmanned aviation based on the applied functions of full-size conventional airports.
