Abstract

Purpose

Path planning is a fundamental and significant issue in robotics research, especially for the legged robots, since it is the core technology for robots to complete complex tasks such as autonomous navigation and exploration. The purpose of this paper is to propose a path planning and tracking framework for the autonomous navigation of hexapod robots.

Design/methodology/approach

First, a hexapod robot called Hexapod-Mini is briefly introduced. Then a path planning algorithm based on improved A* is proposed, which introduces the artificial potential field (APF) factor into the evaluation function to generate a safe and collision-free initial path. Then we apply a turning point optimization based on the greedy algorithm, which optimizes the number of turns of the path. And a fast-turning trajectory for hexapod robot is proposed, which is applied to path smoothing. Besides, a model predictive control-based motion tracking controller is used for path tracking.

Findings

The simulation and experiment results show that the framework can generate a safe, fast, collision-free and smooth path, and the author’s Hexapod robot can effectively track the path that demonstrates the performance of the framework.

Originality/value

The work presented a framework for autonomous path planning and tracking of hexapod robots. This new approach overcomes the disadvantages of the traditional path planning approach, such as lack of security, insufficient smoothness and an excessive number of turns. And the proposed method has been successfully applied to an actual hexapod robot.

Abstract

Purpose

Drawing on anthropomorphism and the stereotype content model, this study aims to explore the impacts of robot anthropomorphism on hotel guests’ word of mouth and continuous usage intention through perceived warmth and competence. This study also investigates the moderating effects of guests’ expertise.

Design/methodology/approach

A total of 524 valid data was collected with Chinese hotel guest through an online survey. Data were analyzed by using structural equation modeling.

Findings

The results indicate that robot anthropomorphism positively affects perceived warmth and competence. Perceived warmth positively affects guests’ word of mouth and continuous usage intention, while perceived competence only positively influences guests’ continuous usage intention. The findings further show that guest expertise weakens the positive relationship between robot anthropomorphism and perceived warmth and competence.

Originality/value

This study advances robot service literature by integrating the stereotype content model with robot anthropomorphism in exploring hotel guests’ perceptions on service robots. This study also discovers the vital boundary role of guest characteristics in human–robot interaction. This study provides valuable information for hoteliers to design and adopt better robots for optimal guest experiences.

The purpose of this study is to provide a micro-nano chip automatic alignment system. Used for micron and nanometer channel alignment of microfluidic chip.

Abstract

Purpose

The purpose of this study is to provide a micro-nano chip automatic alignment system. Used for micron and nanometer channel alignment of microfluidic chip.

Design/methodology/approach

In this paper, combined with the reconstructed micro–nanoscale Hough transform theory, a “clamp–adsorb–rotate” chip alignment method is proposed. The designed alignment system includes a microscopic identification device, a clamping device and a suction device. After assembly, the straightness of the linear slide rail in the horizontal and vertical directions was tested, respectively. The results show that in the horizontal and vertical directions, the linearity error of the linear slide is +0.29 and 0.30 µm, respectively, which meets the requirement of chip alignment accuracy of 15 µm. In the direction of rotation, the angular error between the microchannel and the nanochannel is ±0.5°. In addition, an alignment flow experiment of the chip is designed. The results demonstrate that the closer the angle between the microchannel and the nanochannel is to 90°, the fluid fills the entire channel. Compared with the conventional method, the method and the assembly system realize fully automatic double-layer chip alignment.

Findings

A mechanical device designed by Hough transform theory can realize microfluidic chip alignment at nanometer and micron level.

Originality/value

The automatic alignment device adopts Hough transform principle and can be used for microfluidic chip alignment.

Abstract

Purpose

The relationship between perceived overqualification and knowledge sharing has always been a hot topic, but scholars have come to different conclusions on this issue. The purpose of this study is to integrate conflicting conclusions by considering the moderating role of rewards for knowledge sharing and the mediating role of intrinsic motivation in the relationship between perceived overqualification and knowledge sharing based on self-determination theory.

Design/methodology/approach

The authors collected three-wave survey data from 246 research and development employees in four companies in China.

Findings

The results showed that when rewards for knowledge sharing was higher, employees with perceived overqualification would have higher intrinsic motivation, which could promote their knowledge-sharing behavior. However, when rewards for knowledge sharing was lower, employees with perceived overqualification would have lower intrinsic motivation, thus inhibiting their knowledge-sharing behavior. This result supported the informational function rather than the controlling function of rewards for knowledge sharing.

Originality/value

By considering the important boundary condition of rewards for knowledge sharing, this study reconciles the contradictory conclusions on the relationship between perceived overqualification and knowledge-sharing behavior. At the same time, the authors tell organizations that they can increase the knowledge-sharing behavior of overqualified employees through rewards for knowledge sharing.

Abstract

Purpose

Trust has emerged as a crucial research topic in the sharing economy. However, scholarship on trust in sharing accommodation remains limited. By using stakeholder theory, this study aims to provide a systematic framework for integrating trust among multiple stakeholders and identify potential knowledge gaps and future research directions for trust in sharing accommodation.

Design/methodology/approach

The authors select papers using a combination of multiple keywords from EBSCOhost and Web of Science. The analysis includes 172 journal papers published between 2011 and 2021. The authors conduct a systematic review through thematic content analysis, and each paper is analyzed using manual coding.

Findings

The analysis shows that key stakeholders for trust building in sharing accommodation include consumers, hosts, platforms, residents and governments, with most studies focusing on the consumer perspective. The study integrates various trust antecedents and outcomes from the above multistakeholder. Second, this study summarizes the most commonly used theories, and more diversified theories could be applied to future research. Third, this study finds that most studies use quantitative methods, and researchers should introduce more integrated methodologies such as machine learning on a large scale. Furthermore, the current research disciplinary paradigm should be extended to multidisciplinary and interdisciplinary approaches to promote innovation in trust research. Finally, the COVID-19 pandemic has brought both challenges and opportunities to industry as well as researchers, and more institutional rather than commercial perspectives need to be addressed.

Research limitations/implications

The study contributes to the trust and the sharing economy literature by providing a systematic framework for integrating trust from multistakeholder perspectives. The study also points out several future research directions by combining micro and macro multistakeholder perspectives, identifying more diversified theories and methodologies and specifying multidisciplinary and interdisciplinary approaches.

Originality/value

The study advances knowledge by providing a systematic framework for integrating trust among multiple stakeholders and proposing future research directions for trust in sharing accommodation.

Abstract

Purpose

This paper aims to add to the understanding of dynamic capabilities (DC) as sources of competitive advantage of successful Asian-Pacific shipping companies by demonstrating that DC development unfolds in three steps, from recognition that the environment has changed, to the decision to deploy DC, to assets re-orchestration.

Design/methodology/approach

Based on an approach involving two illustrative case studies, the author analyzed DC development of Chinese and Singaporean-based shipping groups in depth. The analysis was centered on DC by investigating how strategic decision-making on vertical integration, diversification and implementation of new technologies can be underpinned by developing DC to create sustained advantages.

Findings

The author found that strategic components of DC are rooted in strategic decision-making to initiate changes on the corporate and even on an operational level.

Research limitations/implications

While capability development is thoroughly studied, capability erosion has not been integrated into the research. The exploration of human capital as a firm’s idiosyncratic resource in assets orchestration capabilities can be future work.

Practical implications

The proposed research contributes to the debate on micro foundations of DC and provides insights for practitioners striving for retaining competitive advantages.

Social implications

Regarding implications for the society, the research shows how the DC serve to generate competitive advantages. The author has presented a logical structure of the competitive advantage paradigm as a product of DC and business models that can be useful to decision makers.

Originality/value

The research offers insights into the composition of micro foundations of DC and demonstrates that DC can be unbounded into well-known and concrete strategic and operational management activities.

Abstract

Purpose

The purpose of this study is to develop a conceptual model to examine the effect of word-of-mouth in the retailing of Chinese consumer electronics in the US. This study aims to show that word-of-mouth affects directly or indirectly consumer trust-loyalty link for Chinese consumer electronics.

Design/methodology/approach

A research framework was designed to test the direct and indirect relationships with structural equation modelling regarding how word-of-mouth affects consumer trust and loyalty for Chinese consumer electronics in the US consumers.

Findings

The results indicate that word-of-mouth increases consumer trust directly whereas decreases consumer trust through two types of consciousness (i.e. health and price consciousness), resulting in loyalty. The results also show that ethnocentrism moderates the effect of word-of-mouth. For those with low ethnocentrism, the effect of word-of-mouth on trust exists only in the direct route.

Research limitations/implications

The result suggests that retail managers need to carefully consider the positive and negative influences of word-of-mouth to build consumer trust and loyalty when promoting Chinese consumer electronics. Further cross-cultural research should be explored to generalize the moderating influence of ethnocentrism on the relationship between word-of-mouth and trust-loyalty link.

Originality/value

This study contributes to a better and wider understanding of consumer loyalty regarding Chinese consumer electronics by investigating the effect of word-of-mouth and the differential mediating role of multidimensional consumer consciousness with ethnocentrism.
