Abstract

Purpose

This paper aims to demonstrate a cloud-based version of the improved Monte Carlo localization algorithm with robust orientation estimation (IMCLROE). The purpose of this system is to increase the accuracy and efficiency of indoor robot localization.

Design/methodology/approach

The cloud-based IMCLROE is constructed with a cloud–client architecture that distributes computation between servers and a client robot. The system operates in two phases: in the offline phase, two maps are built under the MapReduce framework. This framework allows parallel and even distribution of map information to a cloud database in pre-described formats. In the online phase, an Apache HBase is adopted to calculate a pose in-memory and promptly send the result to the client robot. To demonstrate the efficiency of the cloud-based IMCLROE, a two-step experiment is conducted: first, a mobile robot implemented with a non-cloud IMCLROE and a UDOO single-board computer is tested for its efficiency on pose-estimation accuracy. Then, a cloud-based IMCLROE is implemented on a cloud–client architecture to demonstrate its efficiency on both pose-estimation accuracy and computation ability.

Findings

For indoor localization, the cloud-based IMCLROE is much more effective in acquiring pose-estimation accuracy and relieving computation burden than the non-cloud system.

Originality/value

The cloud-based IMCLROE achieves efficiency of indoor localization by using three innovative strategies: firstly, with the help of orientation estimation and weight calculation (OEWC), the system can sort out the best orientation. Secondly, the system reduces computation burden with map pre-caching. Thirdly, the cloud–client architecture distributes computation between the servers and client robot. Finally, the similar energy region (SER) technique provides a high-possibility region to the system, allowing the client robot to locate itself in a short time.

Abstract

Purpose

To analyse the scope of localization strategies and corresponding benefits of these strategies to subsidiaries of international companies in the automobile industry in Thailand.

Design/methodology/approach

The authors have adopted the case research method to investigate localization strategies of subsidiaries of seven companies (Toyota, Hino, Honda, Isuzu, DaimlerChrysler, BMW, and Auto Alliance) as well as 14 of their dealers and suppliers in Thailand. The information was gathered by conducting in‐depth multiple interviews with 120 local and expatriate employees at various levels in the organizations; by referring to annual reports, policy documents and internal reports of these companies; and by observation during plant visits.

Findings

Contrary to the belief that international companies implement localization strategies to simply match the local market environment, it was found that these companies implement a wide range of localization strategies to achieve multiple benefits. The paper identifies nine areas of localization: localization of strategic decision making; building and exploiting the local knowledge pool; deployment of local human resources; localization of R&D; localization of products; use of local supplier networks; adaptations to manufacturing processes; local deployment of subsidiary profits; and localization of corporate image. These localization strategies are not just based on the principle of “cost‐based localization” but are based on “value‐based localization.” These strategies work in tandem and create value through a system of multiple benefits, such as managements' ability to comprehend and deal with uncertainty in the operating environment; make informed decisions to respond to challenges in developing efficient local assembly and marketing systems; cost reduction; higher degree of commitments by local employees; product customization and acceptance; and greater brand equity and image as a good corporate citizen.

Practical implications

Based on concrete illustrations of seven companies, this study identifies nine distinct areas for planning and implementing localization strategies and their corresponding benefits. The managers of subsidiaries can benefit by focusing their localization efforts in these areas to gain maximum advantage from host country context and then translate these advantages into a competitive international strategy.

Originality/value

CEOs of subsidiaries in emerging markets can learn how to build and harness local advantages for global competitiveness by implementing a wide range of localization strategies.

Abstract

Purpose

Precise vehicle localization is a basic and critical technique for various intelligent transportation system (ITS) applications. It also needs to adapt to the complex road environments in real-time. The global positioning system and the strap-down inertial navigation system are two common techniques in the field of vehicle localization. However, the localization accuracy, reliability and real-time performance of these two techniques can not satisfy the requirement of some critical ITS applications such as collision avoiding, vision enhancement and automatic parking. Aiming at the problems above, this paper aims to propose a precise vehicle ego-localization method based on image matching.

Design/methodology/approach

This study included three steps, Step 1, extraction of feature points. After getting the image, the local features in the pavement images were extracted using an improved speeded up robust features algorithm. Step 2, eliminate mismatch points. Using a random sample consensus algorithm to eliminate mismatched points of road image and make match point pairs more robust. Step 3, matching of feature points and trajectory generation.

Findings

Through the matching and validation of the extracted local feature points, the relative translation and rotation offsets between two consecutive pavement images were calculated, eventually, the trajectory of the vehicle was generated.

Originality/value

The experimental results show that the studied algorithm has an accuracy at decimeter-level and it fully meets the demand of the lane-level positioning in some critical ITS applications.

The purpose of this paper is to propose an enhanced pose tracking method using progressive scan matching, focusing on accuracy, time efficiency and robustness.

Abstract

Purpose

The purpose of this paper is to propose an enhanced pose tracking method using progressive scan matching, focusing on accuracy, time efficiency and robustness.

Design/methodology/approach

The general purpose of localization algorithms is to dynamically track a robot instead of globally locating one. In this paper, progressive scan matching is used to promote the performance of pose tracking. Rotational and translational samples are separately generated to accelerate the calculation and to increase the accuracy. Progressive iteration of sample generation can ensure localization to achieve a specific precision. The direction of localization uncertainty is taken into consideration to increase robustness. Nonlinear optimization is adopted to achieve a more precise result.

Findings

The proposed method was implemented on a self-made mobile robot. Two experiments were conducted to test the accuracy and time efficiency of the method. The comparison with the basic Monte Carlo localization shows the advantages of the method. Another two experiments were conducted to test the robustness of the method. The result shows that the method can relocate a robot from an inaccurate place if the offset is moderate.

Originality/value

An enhanced pose tracking method is proposed to promote the performance by separately processing rotational and translational samples, progressively iterating the sample generation, taking the direction of localization uncertainty into consideration and adopting nonlinear optimization. The proposed method enables a robot to accurately and quickly locate itself in the environment with robustness.

Abstract

Purpose

Recently, service robots have been widely used in various fields. The purpose of this paper is to design a restaurant service robot which could be applicable to provide basic service, such as ordering, fetching and sending food, settlement and so on, for the customers in the robot restaurant.

Design/methodology/approach

Based on characteristics of wheeled mobile robots, the service robot with two manipulators is designed. Constrained by the DOF, the final positioning accuracy within ±3 cm must be guaranteed to successfully grasp the plate. Segmented positioning method is applied considering the positioning costs and accuracy requirement in the different stages, and the shape‐based matching tracking method is adopted to navigate the robot to the object.

Findings

Experiments indicate that the service robot could successfully grasp the plate, from wherever is its initial position; and the proposed algorithms could estimate the robot pose well and accurately evaluate the localization performance.

Research limitations/implications

At present, the service robot could only work in an indoor environment where there is steady illumination.

Practical implications

The service robot is applicable to provide basic service for the customers in the robot restaurant.

Originality/value

The paper gives us a concept of a restaurant service robot and its localization and navigation algorithms. The service robot could provide its real‐time coordinates and arrive at the object with ±2 cm positioning precision, from wherever is its initial position.

Abstract

Purpose

Studies on cross-culture marketing often focus on either localization or globalization strategies. Based on data from pre-communist China (1912–1949), product hybridization – defined as a process or strategy that generates symbols, designs, behaviors and cultural identities that blend local and global elements – emerges as a popular intermediate strategy worthy of further inquiry. After examining the mechanisms and processes underlying this strategy, a schema for classifying product hybridization strategies is developed and illustrated. The paper aims to discuss these issues.

Design/methodology/approach

Critical historical research method is applied to historical data and historical “traces” from pre-communist China’s corporate documents, memoirs, posters, advertisements, newspapers and secondhand sources.

Findings

Strategic interactions between domestic and foreign companies in pre-communist China fostered products and a city (Shanghai) containing Chinese and non-Chinese elements. Informed by historical traces and data from pre-communist China (1912-1949), a 2 × 2 classification schema relating company type (i.e. foreign or domestic) to values spectrum endpoint (i.e. domestic vs foreign) was formulated. This schema reflects the value of communication, negotiation and cultural (inter)penetration that accompanies cross-culture product flows.

Research limitations/implications

Cross-culture marketing strategies meant to help companies satisfy diverse marketplace interests can induce a mélange of product design elements. Because product hybridization reflects reciprocity between domestic and foreign companies that embodies multiple interests and contrasting interpretations of product meanings, researchers should examine globalization and localization synergistically.

Practical implications

Strategies adopted by domestic and foreign companies in pre-communist China (1912–1949) can help contemporary companies design effective cross-culture marketing strategies in a global marketplace infused with competing meanings and interests.

Originality/value

Examining historical strategies adopted in pre-communist China (1912–1949) can inform contemporary marketers’ intuitions. Understanding product hybridization in global marketplaces can improve marketing efficiency.

Abstract

Purpose

This paper aims to conceptualise a framework of “transnational human resource management” (HRM) and to demonstrate the validity of the model.

Design/methodology/approach

Evidence is drawn from survey of 93 large Japanese multinational companies (MNCs). Data are analysed through descriptive statistics, hierarchical multiple regression analyses and mediation effect analyses.

Findings

The analysis reveals that the practices for normative and systems integration are associated with increasing levels of social capital and geocentric staffing, respectively, and the social capital and geocentric staffing fully mediate the relationship between normative and systems integration and transnationality.

Originality/value

The research extends the integration theory in international HRM and demonstrates the validity of our framework for transnational HRM. The authors also shed light on the reality of the integration aspects of international HRM in Japanese MNCs.

Abstract

Purpose

The purpose of this paper is to examine the effect of the interpretation strategy of cultural mixing on consumers’ evaluations of global brands that incorporate local cultural elements. Specifically, this paper examines whether a property interpretation and a relational interpretation have different influences on consumers’ evaluations of global brands that incorporate local cultural elements.

Design/methodology/approach

Two experiments were conducted as part of this research. Experiment 1 adopted a two (interpretation strategy: property interpretation vs relational interpretation) single-factor between-subjects design. Experiment 2 adopted a 2 (interpretation strategy: property interpretation vs relational interpretation) × 2 (polyculturalist beliefs: high vs low) between-subjects design. The data were analyzed using ANOVA and PROCESS 213.

Findings

A property interpretation (emphasizing that some features of a global brand transfer to local cultural elements) leads to a less favorable evaluation of global brands that incorporate local cultural elements than a relational interpretation (emphasizing a relation between global brands and local cultural elements). This effect is fully mediated by perceived cultural intrusion, and it exists only when consumers have a low level of polyculturalist beliefs.

Originality/value

This paper reveals that the phenomenon of cultural mixing occurs when global brands incorporate local cultural elements. In addition, the way that consumers perceive the relationship between global brands and local cultural elements will determine their reactions to global brands that incorporate local cultural elements.

Abstract

Purpose

The purpose of this paper is to design intelligent robots operating in such dynamic environments like the RoboCup Middle-Size League (MSL). In the RoboCup MSL, two teams of five autonomous robots play on an 18- × 12-m field. Equipped with sensors and on-board computers, each robot should be able to perceive the environment, make decision and control itself to play the soccer game autonomously.

Design/methodology/approach

This paper presents the design of our soccer robots, participating in RoboCup MSL. The mechanical platform, electrical architecture and software framework are discussed separately. The mechanical platform is designed modularly, so easy maintainability is achieved; the electronic architecture is built on industrial standards using PC-based control technique, which results in high robustness and reliability during the intensive and fierce MSL games; the software is developed upon the open-source Robot Operating System (ROS); thus, the advantages of ROS such as modularity, portability and expansibility are inherited.

Findings

Based on this paper and the open-source hardware and software, the MSL robots can be re-developed easily to participate in the RoboCup MSL. The robots can also be used in other research and education fields, especially for multi-robot systems and distributed artificial intelligence. Furthermore, the main designing ideas proposed in the paper, i.e. using a modular mechanical structure, an industrial electronic system and ROS-based software, provide a common solution for designing general intelligent robots.

Originality/value

The methodology of the intelligent robot design for highly competitive and dynamic RoboCup MSL environments is proposed.
