The purpose of creating the structure was to enable the increased mobility of an adult over short distances in an urban-ized environment. The whole design work was divided into several parts. In the first stage, requirements were assumed for the design of the device, electrical elements chosen, and a diagram of their electrical connections is presented. In the second part, the created CAD model of the structure is presented and some of mechanical elements described. In order to check the strength of the structure, the FEM analysis of the device body was carried out. The penultimate part was to analyze the problem of the inverted pendulum, which allowed to separate the state space model into a base subsystem and a control stick subsystem necessary to develop the control for the platform. In the last part, a stabilizing algorithm based on the LQR regulator was prepared and the use of sensory fusion in the form of a Kalman filter was focused on in order to increase the accuracy of determining the angle of deflection of the structure. Finally, simulations were prepared in the Simulink environment in order to check the correctness of the prepared algorithm. The whole was crowned with a summary of the work and setting directions for further research.","PeriodicalId":354390,"journal":{"name":"Mining - Informatics, Automation and Electrical Engineering","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121203874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combustion of solid fuels is a complex process that requires proper preparation of the fuel, carry-ing out the combustion process, as well as the removal of harmful substances in the form of dust and gaseous pollutants (NOx, SOx, CO) from exhaust gases emitted into the environment. For decades, the gaseous form has been considered the noblest form of fuel. Gaseous fuels can be easily transported over long distances, are immediately ready for combustion and the composition of the fuel mixture can be freely adjusted. The con-stant pursuit to reduce anthropogenic greenhouse gas emissions require the use of low-emission and zero-emission energy generation technologies. In the case of coal, this will mean a shift from direct combustion to more advanced systems powered by gaseous fuel. The paper presents an overview of the available techniques and technologies of solid fuel gasification aimed at the production of gaseous fuels, which can be used in low-emission energy technologies. The computational methods of the gasification process are also presented, which allow the selection of the best technology and operating parameters of individual reactors.","PeriodicalId":354390,"journal":{"name":"Mining - Informatics, Automation and Electrical Engineering","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115322799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Other methods can be used to reduce the physical effort of handling the wall.
