Also, in the video-conference mode, the project "Development of an intelligent robotic biobank system for storing and transporting biological material" was presented. Industrial partner of the project BINAM LLC. The project leader, Doctor of Technical Sciences, Professor Larisa Rybak told about the results of the project: “At the first stage of the project, a database of actual storage conditions for biological samples was formed, including temperature conditions, storage duration and data on biobanking subjects (including anthropometric data, anamnestic data and data from clinical studies of health status).
An algorithm for the technological process of biobanking has been developed, including the preanalytical process of preparing samples, transporting them, storing and unloading at the request of the operator. Methods for approximating the working area of a robot with 4 degrees of freedom, based on the concept of uneven coverings, have been developed, and an algorithm has been synthesized for approximating the set of solutions, both systems of nonlinear equations and inequalities describing constraints on the parameters of the robot. On the basis of the required movements of the robot in accordance with the technological process of biobanking, the boundaries of the required working space were determined, which made it possible to determine the range of linear and angular displacements of the actuators, and, consequently, the geometric parameters of the PC as a whole. Kinematic and dynamic models of the RS have been developed based on the Euler-Lagrange equations, taking into account the characteristics of drives and sensors. " In the project of LLC "Stroitel", implemented jointly with BSTU named after V.G. Shukhov "Creation of an integrated technology for the processing of gypsum-containing waste from industrial enterprises" (project manager from the university, Ph.D., associate professor Natalya Alfimova) in 2021 the parameters (temperature, moisture content of raw materials) for the manufacture of gypsum binders from gypsum-containing waste were optimized, the possibility of using citrogypsum was established during composting of poultry waste, the processes of manufacturing and hardening of alkali-activated binders based on OEMK slag with the addition of gypsum-containing waste - citrogypsum have been studied and an electronic-digital model has been developed and draft documentation of a drying drum has been prepared for a line for processing gypsum-containing waste. Within the framework of the project "Development of technology for the production of light-scattering additives and texture (shagreen) for the production of polycarbonate light diffusers used in the field of crop production, animal husbandry and industrial lighting", implemented by LLC "Plasticglass" in conjunction with BSTU im. V.G. Shukhov (project manager from the university, Ph.D., associate professor Roman Lyubushkin), the technological parameters of the equipment were selected according to the method and sequence of adding the mixture components for compounding, mixing and modification of the developed light-scattering additive; selected light-scattering additives based on domestically produced acrylic and glass microspheres; the approbation of the operational and optical properties of the light diffusers was carried out; light-scattering additives are introduced into the polycarbonate binder; screening of functional additives for light-scattering composites based on polycarbonate of various chemical nature was carried out, the most promising ones for further research were proposed.
Three types of thermodynamically incompatible or limitedly compatible with the polymer matrix of compounds were considered: organic, polymers and copolymer particles, wax of various nature. Hard inorganic fillers, aluminum oxide, silicon dioxide, quartz, titanium dioxide, bentonites, barium sulfate, hydrophobic chalk. Hybrid fillers, organic-inorganic additives, which are globular polymer particles with a surface grafted with hydrophilic groups of inorganic nature. Of the three types of potential light-scattering additives, the most promising ones were selected, which will be studied in the next stage of research, compatibility with a polycarbonate matrix, the possibility of introducing by extrusion and their functional properties. Within the framework of the project "Industrial complex for deep processing of vegetable oils based on innovative technology of controlled organic synthesis", implemented by LLC Yamshchik (project manager from the university, Ph.D., associate professor Valentina Poluektova), a comprehensive analysis of the technological scheme for obtaining alkyd resins used in the chemical and paint and varnish industry, the main stages of the technological process of obtaining alkyd resins, as well as the analysis of the main technological equipment and the technical parameters of the complex are determined. The main technological equipment for the synthesis of alkyd resins is a reactor in which the main chemical processes take place. A digital design of the reactor was carried out, during which an electronic-digital model of the equipment was developed, an engineering analysis was carried out, and sketch design documentation was developed, as well as an improved technology for producing alkyd resins was developed. It is also planned to develop recommendations for the design of equipment for the production of alkyd resins. At the moment, the final design is being coordinated with the Yamshchik LLC enterprise.
