An Improved Artificial Potential Field Method with LiDAR for Autonomous Navigation in Dynamic Food Production Environments Chenghan Yang, Dingkun Zheng, Aiym Koshanova, Baurzhan Belgibaev, Talshyn Sarsembayeva, Baidong Zhao Sist 2025 2025 IEEE 5th International Conference on Smart Information Systems and Technologies Conference Proceedings, 2025 The rapid development of robotics has transformed industrial automation, with significant advancements in the food industry. Autonomous navigation is critical for enhancing efficiency and flexibility in dynamic production environments, where robots transport raw materials and semi-finished products across facilities. Traditional Artificial Potential Field (APF) methods, while effective for real-time obstacle avoidance, often face challenges such as local minima, limited dynamic obstacle handling, and unsmooth paths. To address these limitations, this study proposes an improved APF method integrated with LiDAR for real-time perception and dynamic field generation. The approach incorporates global path guidance to overcome local minima, Kalman filtering for dynamic obstacle state prediction, and Bezier curve smoothing to enhance path continuity and stability.Simulation experiments conducted in a food production environment demonstrated significant performance improvements. The proposed method achieved a 5.6-meter average path length, 97% obstacle avoidance success rate, and 55 ms planning time, outperforming the traditional APF method. These results validate the enhanced adaptability, efficiency, and safety of the improved APF in dynamic environments. This study provides a robust and efficient navigation solution for intelligent food manufacturing, contributing to the broader adoption of autonomous systems in industrial applications.
PLASMON RESONANCE IN THIN ZnO FILMS WITH NANOPARTICLES OF NOBLE METALS A. B. Koshanova, R. R. Nemkayeva, N. G. Guseinov, A. A. Markhabayeva, Ye. S. Mukhametkarimov Herald of the Kazakh British Technical University, 2024 The main disadvantage of traditional metal oxides, including zinc oxide (ZnO), is poor absorption of light in the visible range. Among the many ways to solve this problem, the creation of their composition with noble metal nanoparticles (NPs) is the most interesting from both practical and theoretical points of view. Due to the effect of localized surface plasmon resonance (LSPR), characterized by a light absorption band in the visible range, the functionality of oxide semiconductors can be significantly improved. This work presents the results of preparation of composite films based on ZnO with nanoparticles of noble metals (silver Ag, gold Au and their alloy AgAu) by magnetron sputtering, as well as the analysis of the LSPR effect in these composites. In ZnO:AgNPs films, the LSPR absorption was observed at 475 nm, while for ZnO:AuNPs at 535 nm. The AuAg alloy nanoparticles exhibit a maximum in the intermediate interval of these two values, i.e., in the region of 508 nm. The obtained data indicate that by controlling the composition of noble metal nanoparticles it is possible to effectively control the light absorption band in the visible range.
Electric explosion nickel nanopowders G. Partizan, B. Z. Mansurov, B. S. Medyanova, A. B. Koshanova, B. A. Aliev Technical Physics, 2016 The structure and the morphology of the nickel nanopowders synthesized by an electric explosion of a metallic wire are comprehensively studied. The results of scanning and transmission electron microscopies show that the nickel nanoclusters have a spherical shape with an average diameter of 50 nm. An analysis of X-ray diffraction patterns demonstrates that the lattice parameter of the electric explosion nanopowder particles is larger than the standard parameter. The results of computer experiments agree well with the conclusions drawn from X-ray diffraction data. However, the causes of the lattice distortion in the nickel nanoclusters are still debatable.
Synthesis of carbon nanostructures on iron nanopowders A Koshanova, G Partizan, B Мansurov, B Мedyanova, M Mansurova, B Aliev, Xin Jiang Journal of Physics Conference Series, 2016 This work presents the results of experiments on synthesis of carbon nanostructures (CNs) by the method of thermal chemical vapor deposition using iron nanopowders obtained by the method of electrical explosion of wires as catalysts. To study the process of nucleation and growth of individual carbon nanostructures, experiments were conducted not only on nanopowders, but also on the separated clusters. To determine the optimum conditions of the carbon nanostructures synthesis and lower temperature limit, experiments were performed at different temperatures (300-700°C) and pressures (100-400 mbar). The experiments have shown that the lower temperature limit for carbon nanostructures synthesis on the iron nanopowders is 350°C and in this process the growth of carbon nanostructures is not so massive. Stable growth of carbon nanostructures for nanopowders began from 400°C during the entire range of pressures. The analysis of Raman spectroscopy showed that the most optimum conditions for obtaining nanotubes of high quality are P = 100 mbar and T = 425°C.
Synthesis of micro- and nanodiamonds by the method of oxy- acetylene combustion flame S Sabitov, B Mansurov, B Medyanova, G Partizan, A Koshanova, Ye Merkibayev, M Mansurova, B Lesbayev Journal of Physics Conference Series, 2016 This work presents the results of experiments on synthesis of micro- and nanodiamonds by the method of oxy-acetylene torch on the surface of pre-deposited copper thin films. The influence of the thickness of the buffer copper film and the concentration ratio of oxygen and acetylene on the structure formation of the deposited samples was investigated during performed experiments. Studies by Raman scattering and scanning electron microscopy showed that the synthesis of micro- and nano-diamonds occurs under certain experimental conditions.
Synthesis of carbon nanofibers on copper nanopowders by low-temperature CVD G. Partizan, B. Z. Mansurov, B. S. Medyanova, A. B. Koshanova, M. E. Mansurova, B. A. Aliyev, X. Jiang Eurasian Chemico Technological Journal, 2016 The article presents the results of experiments on the synthesis of carbon nanofibers by thermal chemical vapor deposition using copper nanopowders obtained by electric explosion of wire as catalysts. Stable growth of carbon nanofibers was carried out at temperatures significantly lower than normally used. The process parameters that are optimal for low-temperature growth of carbon nanofibers have been identified during the performed experiments. The synthesized samples have different diameters and morphology (from spiral to direct). Copper clusters are both at the ends and inside the fibers. The results of IR spectroscopy indicate that the structure of the obtained carbon nanofibers is polymeric. X-ray analysis revealed the presence of a halo on the diffraction patterns at small values of the angle 2θ, which proves that the grown structures have an amorphous nature. There are no groups that are responsible for long-range order in all Raman spectra. Studies by transmission electron microscopy showed that nanostructures do not have an internal channel and nanofibers are solid.
