This paper presents the results of research on the development of technology for supervisory control of mechatronic devices through the Internet. We propose a hierarchical structure for the management of a group of mobile robots (a group of mechatronic devices) by combining their information-measuring and control systems into a local area network. The main requirements to the functional structure of these systems are formulated. The development of a spatially distributed control system involves a number of problems associated with peculiarities of the use of digital radio and Internet channels. These problems can be treated by creating specialized software and hardware tools, such as the spatially distributed scientific and educational Internet-laboratory proposed in this paper. The laboratory can be used to organize full-fledged access to specific mechatronic systems of different models and different producers through the Internet. The main requirements for the implementation of this laboratory are formulated through the use of the "concept of drivers". The architecture and technical implementation of the pilot project of this laboratory are described. The driver concept designed for incorporating the mechatronic devices into the structure of the laboratory is demonstrated by the example of the AMUR and Festo Robotino robots.The work was supported by the Russian Academy of Engineering, project "Intelligent Robotronics" and partially by the Russian Foundation for Basic Research, project nos. 13-07-01032 and 13-07-00988. © 2015 The Authors.

This article examines the challenges of development of a geometric modeling system for modular machine tools. Possible universal components of machine tools are listed. An analysis of requirements for the machine tool assembly visualization system is conducted. Based on this analysis development tools are selected and the process of the development is described. An example of database creation of standardized components of modular machine tools for industrial systems is shown. Another example illustrates a fragment of the automated data management subsystem for building visualized layouts of modular machine tools. This visualization system helped to solve problems of constructing layouts of modular machine tools for flexible production lines in the processing of body parts such as the gearbox, developed by the Moscow Special Design Bureau of automatic lines and modular machine tools (ISO SKB AL and AS).

The method of organization of network management for robotic systems from different manufacturers without modification of their low-level code is described. The method is based on the "concept of drivers". It is similar to the external device drivers for various operating systems. The requirements for the hardware and software architecture of the interaction of robotic systems of different models and manufacturers were defined. The development of a "driver" for mechatronic gripper module of AMUR (ML "Sensorika") educational robot is shown as a specific example of driver's development stages.

In the current study, velocities of aluminum, zinc, and copper particles accelerated in an axisymmetric cold spray micronozzle are numerically simulated and experimentally measured. It is found that aluminum and zinc particles can be accelerated to velocities close to the critical values in a supersonic nozzle with 1-mm exit diameter, 0.5-mm throat diameter, and 20-mm length when helium is used as the process gas. The diameter of the particle jet delivered by the micronozzle does not exceed 1.3 mm for any of the types of the tested powders. © 2012 ASM International.

Cold spray is a material deposition technique based on the high velocity particle-substrate impact. The last researches in this field show that efficiency of deposition depends not only on the particle impact velocity but also on the impact temperature. In order to control the particle impact temperature, a special powder preheater installed between the powder feeder and the nozzle could be applied. In the current paper, an influence of powder preheating on the particle impact parameters is numerically studied. Two cases with powder injection to subsonic and supersonic regions of the nozzle are considered. It is shown that artificially preheated 10-50. μm copper particles axially injected to the supersonic region of the nozzle have higher impact temperature than the particles injected to the nozzle prechamber. This effect could be explained by the dependence of duration and intensity of gas-particle heat exchange on the location of powder injection point. It was also shown that in the case of powder injection to supersonic zone, the application of powder preheating could shift the particle impact parameters towards the deposition window without increasing the working gas stagnation temperature. © 2013 Elsevier B.V.

Cold spray deposition of 1-3. mm thick 316L coatings on aluminium substrate using nitrogen as a carrier gas is considered. Dependence of coating properties on particle size distribution and spraying strategy is studied. It was obtained that the absolute value of coating porosity depends on particle size distribution and could be varied from 3% (fine powders) to 8% (coarse powders). The pores are mostly concentrated along the boundaries between deposited layers and the shape of the boundaries is strongly influenced by spraying strategy. It was found that coating deposited using coarse powder has higher microhardness than the one deposited using fine powder, whereas adhesion does not depend on powder granulometry. Eventual decrease of coating porosity is analyzed. In particular, it is shown that laser post re-melting of the deposited coatings can decrease the porosity in the near-surface layers down to <1% with limited heat input to aluminium substrate. Evaluation of anodic polarization behavior showed that corrosion resistance of the laser-treated coating is close to the bulk material whereas performance of as-sprayed coatings is significantly lower. © 2013 Elsevier B.V.

Behavior of an axisymmetric cold spray supersonic gas-particle jet passing through an axisymmetric aperture having a diameter smaller than the jet dimensions is considered. The particular case studied in the paper is the interaction between a supersonic jet delivered by a nozzle with a 7.8 mm exit diameter and a solid plate with a 3 mm aperture. The gas and aluminum particle parameters after passing through the aperture are experimentally and numerically studied. Under conditions used in this study, the decelerating influence of the aperture on the aluminum particle velocity is found negligible for spray distances less than 40 mm. © 2013 ASM International.

In this paper, the application of cold spray (CS) coating deposition technology as additive manufacturing technique is discussed. Absence of material melting during CS deposition permits to obtain deposits with low value of residual stresses and to preserve the phase composition of source material which is a very important advantage. In this paper, the latest developments in the field of cold spray such as micronozzle device and new multimaterial deposition approach permitting to significantly enlarge the potential of cold spray as additive manufacturing technology is discussed. © Springer-Verlag London 2013.

Cold spraying (CS) is a relatively new material deposition technique based on the phenomenon of high-velocity particle/substrate impact. In this process, the powder is accelerated to supersonic speed in specially developed supersonic nozzles in which air, nitrogen or helium is usually employed as a powder carrier gas. In the absence of melting, oxidation and thermal decomposition of a particle in-flight during CS, the deposited coatings demonstrate low residual stresses and preserve the initial phase composition of the source material, which are important advantages for spraying temperature sensitive powders including nanostructures and nanocomposites. In the present paper the review in the field of development of cold spray technology is performed. Different scientific and technological aspects of CS such as surface activation, nozzle geometry, powder preheating, powder injection, control of spatial resolution of particle flux and proper selection of spraying parameters are discussed. © 2014 Elsevier B.V.
