Line following robots are applied in numerous applications and the best performance could be obtained if the forward looking camera is applied. Variable light and line conditions influence the line estimation and quality of the robot navigation. Proposed History Dependent Viterbi Algorithm and Viterbi Algorithm are compared. Obtained results using Monte Carlo tests show improved performance of the proposed algorithm for assumed model.


VR technology is an emerging IT innovation that greatly affects consumer behaviour and consumer perception of products. The aim of this study is to examine how the virtual reality phenomenon can be used as a marketing communication tool and how its usage affects the reception of individual components of a marketing message. The research conducted examined the possible impact of virtual reality on message perception and attitude towards particular offers. Additionally the authors wanted to find out whether there was a relationship between the use of virtual reality and the acceptance of new technologies in marketing communication. To verify the stated hypotheses empirical research was conducted involving an experiment with 150 observations of respondents taking advantage of three different marketing communication tools including: VR presentation with Oculus Rift hardware, video and printed advertisements. The results obtained reveal that VR technology positively and significantly impacts the reception of the offer, the technology involved and the presentation itself.


The holistic approach to Industry 4.0 requires a broader look at the changes taking place in the area of marketing. Therefore, this article mainly aims to present an outline of changes in marketing for companies implementing the concept of Industry 4.0 in the context of Design Principles of Industry 4.0. The authors propose a conceptual framework for Marketing in Industry 4.0, deriving from the guidelines for designing strategies to implement Industry 4.0.

The paper allows a better understanding of the Industry 4.0 phenomenon in the context of changes in the area of marketing in general and in industrial markets in particular. The conceptual framework presented in the article suggests a need for a new approach to shaping marketing strategies and the marketing mix in the Fourth Industrial Revolution and helps in identifying the key areas for the marketing mix according to the Industry 4.0 concept.


Purpose: The paper explores the paradigm shift occurring in the automotive retailing industry since the advent of technological innovations and different solutions in mobility. Existing studies and literature focus on the specific aspects of this changing trend, which is why this paper concentrates on the holistic changes that include various approaches to the issue of disruptive innovation in automotive retailing.

Methodology: To answer the research questions, the article utilizes qualitative research approach in combination with inductive-interpretive analysis. Interviews with eight top-level professionals from the automotive industry reveal three different perspectives on the subject. The study analyzes interview results with coding methodology and MaxQDA software.

Findings: The findings center on two components of research: major trends and impacts. The trends include the changing approach towards usership rather than ownership and to clustered habitation in mega cities. What is evident is the stark impact of such trends as the rising popularity of battery electric vehicles, autonomous cars, and mobility as a service on the dealership model of retailing. The impacts include the falling need and demand for personal cars, the rise of large fleet services like car subscription or lower maintenance needs that are expected to drastically reduce the importance of dealership.

Limitations: To further understand the trends in automotive retailing, future researchers should focus on local trends in specific regions. Another limitation is linked with exclusive concentration on experienced professionals as sources of data.


Purpose: The willingness of consumers to engage in co-creation activities is affected by multiple factors, including intrinsic motivation, firm-level factors, and expected outcomes of the participation in co-creation process. However, the final decision of customer engagement in co-creation is determined by the level of brand attachment and love experienced by customers, product category, and the type of needs satisfied with the object of co-creation. The current research proposes a holistic view of the abovementioned factors and variables by exploring their relationships and mutual influence.

Methodology: This study analyzes the results of qualitative research on the dynamics between positive client attitude toward a brand and the willingness to engage in co-creation activities.

Results/Findings: The study reveals that the willingness to engage in co-creation activities is strongly related to the level of brand attachment except for when people conduct such activities to experience the process itself. The level of customer satisfaction from participation in co-creation processes influences their future sense of brand love and attachment. Moreover, the way and strength of customer engagement in co-creative projects are affected by the product category. The authors especially stress the importance of a strategic approach toward designing and implementing co-creation projects and the key role of appropriate communication with participants.


The article presents investigation of flow around wing of TS-11 Iskra airplane. The flow visualization around 3D printed model of wing with flow control surfaces was performed in a water tunnel. Two configurations were investigated: first with a flap and second with an aileron. The flow visualisation was performed with a use of a dye. The geometry of model was prepared with use Computer Aided Design (CAD) software basing on scans of real object and technical documentation. The model was built with use of additive manufacturing technology. Movement of the flow control surfaces was remotely controlled with servomechanisms incorporated in channels inside the model. In order to perform qualitative validation of the results the investigated flow was simulated with use of CFD commercial software. The article presents visualisation results of flow around wing section of TS-11 Iskra airplane and water tunnel model preparation. In order to perform qualitative validation of the results the investigated flow was simulated with use of CFD commercial software. The goal of the research was to investigate the complex flow field in the vicinity of flow control surfaces and provide aerodynamic characteristics at various deployment angles via numerical simulations. The results can be used for verification of water tunnel testing procedures and training.
