Abstract: Firstly we describe the linguistic approach to the definition of drivers preferences about transport safety project design as humanistic system in Zadeh's sense. Then we short describe introductory research. Eight drivers were asked to evaluate their level of danger in the 14 different traffic situations. Following we propose F. Herrera model; selection process-applied of linguistic dominance degrees as useful for modeling drivers preferences. Finally we make short remark about mathematical generalization suggested Herrera's model as L-(lattice) fuzzy sets. Additional to theoretical approach our research was carried in order to determine the training project for groups of drivers to prevent accidents involving trucks.

Abstract: The article describes technical specification requirements of the international ISO / TS 16949 related to measurement systems assessment. These requirements were confronted with specific customer requirements (CSR) of the VW group included in the VDA 5 manual. On an example of a company from the automotive industry, authors presented the main differences in the two approaches to the same problem and the resulting consequences arising during external audits performed by customers and certification bodies.

Abstract: The paper describes the state of the development, production and utilization of industrial and service robots. It shows the fields of highest deployment of robots. The year 2010 was a break-through and since that year the production of industrial robots has increased each year and the estimated number of produced robots in 2015 is 200 000. The paper also points out the increasing trend of use of service robots as well as mentions main producers and countries with high potential deployment of robots.

Abstract: An important task of designing the robotic assembly stand is to ensure the reliability and accuracy of the parts mating process. This can be achieved by selection of the appropriate method of assembling and by providing the required accuracy of the devices in the kinematic chain of assembly operation. Using high accuracy equipment and instrumentation leads to an increasing of the probability of correct realization of the process of parts mating, but this greatly increases the cost of assembly stand. The use of too precise and complex equipment to robotize the assembly process can be highly uneconomical. This paper presents a mathematical model that allows the selection of the parameters of the modular assembly robot performing the process of mating parts with flat and cylindrical surfaces, which represent the largest share among all the assembled parts. The presented model allows for the optimal selection of the accuracy of each robot modules which ensures reliable realization of assembly process without unnecessary increasing their accuracy, and therefore the stand cost. In the final part of the paper, the results of the model solution have been presented.

Abstract: Digital photogrammetry is a method, which is still seeking for its place in creating 3D models in engineering practice. To digitize and create 3D models using this method we need a digital camera and for processing images of objects photogrammetric software and PC.

Abstract: The development of robotics caused the creation of new solutions in robots communication. Nowadays, there is a need to create not only systems of cooperation between robots and/or their equipment, but also in the relation human-robot. The paper presents the idea of software supporting the collaboration between human and industrial robot. First of all, different types of cooperation in robotics are described. Moreover, a communication solution and computer software proposal are presented. In the final part of the paper the authors present the application developed and the results of experimental work.

Abstract: This article describes the possibilities of identifying a randomly distributed objects due to the removal of parts from the conveyor belt, which is part of the workplace for assembly of the components. A specific feature of this work is that the installation is carried out with the robot SCARA, which take parts from the conveyor. Parts on the conveyor are unoriented, therefore it is necessary to use a camera system to detect the position and orientation of parts. Because of this, it is necessary to carry out the control lines across the moving conveyor. Recognition, identification, location and orientation of the proposed method is sufficiently robust and easily adaptable to the different type of components.

Abstract: Presented paper describes experimental bin picking using Kinect sensor, region-growing algorithm, latest ROS-Industrial drivers and dual arm manipulator Motoman SDA10f.As well known if manipulation with objects of regular shapes by suction cup is required, it is sufficient to estimate only 5DoF for successful pick. In such a case simpler region growing algorithm may be used instead of complicated 3D object recognition and pose estimation techniques, resulting in shorter processing time and decrease of computational load. Experimental setup for such a scenario, manipulated objects and results using region growing segmentation algorithm are explained in detail. Video and link to open-source code of described application are provided as well.

Abstract: The article deals with designing of research robotized workplace, in which will be verified chosen algorithms for identification and also methods for reliably gripping of randomly oriented objects. By using CAD system is created 3D construction documentation. Design of research robotized workplace mainly consists from industrial robot SCARA, control PC, vibratory tray and vibratory conveyor, grippers, linear and rotary modules, drive motor and other equipment for workplace.

Abstract: The article presents selected issues associated with the use of adhesive joints in the assembly of ball bearings in the gearbox housing. The aim of the study was the comparative analysis of adhesive joints strength of gear bearing housings. One series of rings, simulating the new socket fits with different parameters and different degrees of wear were used to comparison of these joints.The tests were conducted on two series of rings, to represent new housing of different fit parameters and wear variants. The three types of tested adhesives are frequently found in similar applications. The rings and two types of bearings were tested: single row ball bearings 6207Z and tapered roller bearings 30207A. The comparative analysis of tested adhesives indicates the superiority of Loctite products over Chester Molecular B36 adhesive. In tapered roller bearings Loctite 542 produced the strongest bond.
