Opis:: Cobotics refers to the design, production, study, and use of work systems in which one or more operator(s) interact(s) with one or more robot(s) in a shared space or remotely. This type of system is increasingly present in industry. It aims to improve how things are produced in terms of performance and health/safety by drawing on the respective strengths of operators and robots. Cobotic systems (comprising the operator, robot and task/environment) cannot be designed and put into service without anticipating difficulties related to technical complexity, the use of the system, and the industrial process. With this in mind, this article proposes to design systems based on simulations using an interdisciplinary approach drawing on ergonomics, robotics and cognitive engineering.
Cobotyka odnosi się do projektowania, produkcji, badania i korzystania z systemów pracy, w których jeden lub więcej operatorów współdziała z jednym lub więcej robotami w przestrzeni wspólnej lub zdalnie. Ten rodzaj systemu jest coraz częściej obecny w przemyśle. Ma on na celu poprawę sposobu realizacji zadań pod względem wydajności i bezpieczeństwa/ zdrowia przez wykorzystanie odpowiednich mocnych stron operatorów i robotów. Systemy Cobotic (obejmujące operatora, robota i zadania / środowisko) nie mogą być projektowane i uruchamiane bez przewidywania trudności związanych ze złożonością techniczną, wykorzystaniem systemu i procesem przemysłowym. Mając to na uwadze, niniejszy artykuł proponuje zaprojektowanie systemów opartych na symulacjach z wykorzystaniem podejścia interdyscyplinarnego opartego na ergonomii, robotyzacji i inżynierii kognitywnej.

Opis:: In the paper, an effective way to design asymmetrical optics for a uniform vertical surface illumination was presented. Assessment of the obtained distribution of luminance (illuminance) on the illuminated surface is done almost at the same time as designing the optical system elements. Advantage of the final application of the presented method in 3D will be independence from the implementation of time-consuming simulations in order to verify the already designed optics. Understanding the method and its application is simple and intuitive. Observing the luminance distribution, created on the illuminated surface almost at the same time as its design, allows to see the effect of adding the next elements of the optical system on this distribution.

Opis:: We present 30 fs pulse duration home-made chirped pulse amplification Ti:sapphire laser system operating at a repetition rate of 1 kHz with 4.0 mJ pulse energy. The Ti:sapphire laser system with ım819 nm center wavelength has a long-cavity oscillator, four pass grating stretcher, 8-pass pre-amplifier, 4-pass post-amplifier and a double pass grating compressor. The Peltier coolers and thermal eigenmode post-amplifier are introduced to compensate the thermal lensing of the crystal in the amplifiers and to enhance the beam focusability on the crystal. The Strehl ratio and M² value measured by employing the Shack-Hartman wavefront sensor HASO4 to observe the spatial profile and beam quality. The most sensitive single-shot second harmonic generation frequency-resolved optical gating diagnostic technique is employed to characterize intensity and phase of the output compressed laser pulses.

Opis:: This paper presents modern methods for designing optical systems for luminaires in the context of long years of light sources development. It shows that the development of technology for producing increasingly precise optical systems has led to an evolution in the construction of luminaires with increased efficacy and utilizing more efficiently the features of a specific family of light sources. Methods for designing and modelling optical systems with the use of mathematical curves as well as advanced the free-forming method are described. The paper also shows methods for modelling light sources features, especially luminance ones, designed to make precise simulation calculations required in any luminaire design process. Knowledge of luminance distributions of light sources and precise luminance distributions of optical systems for luminaires raises the design process to a very high level, enabling positive modern light source features, such as high luminance and their small dimensions, to be used consciously while minimizing negative ones, such as discomfort glare, caused by luminaires. The paper presents the results of simulation calculations and laboratory measurements for a selected case of luminaire equipped with a discharge lamp of maximum luminance exceeding 30 million cd/m2.

Opis:: Designing, optimizing and analyzing optical systems as part of the implementation process into production of modern luminaires require using advanced simulation and computational methods. The progressive miniaturization of LED (light emitting diode) chips and growth in maximum luminance values, achieving up to 108 cd/m2, require constructing very accurate geometries of reflector and lens systems producing complex luminous intensity distributions while reducing discomfort glare levels. Currently, the design process cannot function without advanced simulation methods. Today’s simulation methods in the lighting technology offer very good results as far as relatively large conventional light sources such as halogen lamps, metal halide lamps and high pressure sodium lamps are concerned. Unfortunately, they often fail in the case of chip-on-board LED light sources whose luminous surface dimensions are increasingly often contained inside a cube of the side length below 1mm. With the high sensitivity of such small chips and lenses with dimensions ranging from a just a few to between 10 and 20 mm, which is presented in this paper, modern luminance distribution measurement methods, luminance modelling and ray tracing methods should be used to minimize any errors arising from incorrectly projecting the design in the final physical model. Also, very importantly, focus should be directed towards reducing a chance of making a mistake while collimating the position of the light source inside the optical system. The paper presents a novel simulation calculation method enriched with an analysis of optical system sensitivity to a light source position. The results of simulation calculations are compared with the results of laboratory measurements for corresponding systems.

Opis:: The paper presents the method suitable for optimization of parameters and applied to design aircraft subassemblies on the example of a swept wing. It outlines the assumptions that are necessary to develop a mathematical model and describes constraints that served as the basis to develop an algorithm and describe the corresponding procedures in the GRIP (Graphics Interactive Programming) language that is a part of the CAD/CAM/CAE Unigraphics system. The further part of the study comprises discussion how the wing parameters and the mass functional are affected by the rigidity constraints and strength constraints. The algorithm for designing aircraft components was finally developed with inputs to the multicriteria design process “Web Modelling” of an aircraft body. The study also includes initial assumptions to algorithms originally developed by the author and dedicated to the modelling of components incorporated into aircraft structures.

Opis:: Oil and gas industry processes are associated with significant expenditures and risks. Adequacy of the decisions on safety measures made during early stages of planning the facilities and processes contributes to avoiding technological incidents and corresponding losses. Formulating straightforward requirements for safety instrumented systems that are followed further during the detailed engineering design and operations is proposed, and a mathematical model for safety system design is introduced in a generalized form. The model aims to reflect the divergent perspectives of the main parties involved in oil and gas projects, and, therefore, it is formulated as a multi-objective problem. Application of black box optimization is suggested for solving real-life problem instances. A Markov model is applied to account for device failures, technological incidents, continuous restorations and periodic maintenance for a given process and safety system configuration. This research is relevant to engineering departments and contractors, who specialize in planning and designing the technological solution.
