Currently, the topic of automation of logistic processes in warehouses is relevant. The article considers a control system of high level for a mobile robot with a differential drive with a maximum payload of 200 kg with motion simulation in the Matlab Simulink software product. Optimal control of drives based on brushless DC motors at the lower level has been developed. The transient time of low level control system is 1.067 seconds. The mobile robot control system in the minimum version consists of ten ultrasonic distance sensors located along the perimeter of the mobile robot body and of eight contrast band sensors.

Spiroid gear is one of the progressive varieties of intersecting axis gears. It has a number of advantages: increased overlap coefficient, favourable contact conditions. Spiroid gears are notable for high loading and overloading ability, increased smooth running and less sensitivity to manufacturing and assembly errors, high reliability and durability. The analysis of the results of experiment on research of vibration of the spiroid gear PS-124 has shown, that the vibration level at frequency 200-300 Hz is reduced on 5 dB at increase of the resistance moment up to 1000 Nm at clockwise rotation of the reducer and at increase of the resistance moment up to 800 Nm at counter-clockwise rotation of the reducer. The vibration level at frequency 700-800 Hz is also increased on 5 dB at increase of the resistance moment up to 1000 Nm at clockwise rotation of the reducer and at increase of the resistance moment up to 800 Nm. If these vibration levels are exceeded, a defect is likely to occur. Economic efficiency of application of diagnostics systems is caused by increase of reliability and quality, reduction of accidents, decrease in defects, reduction of idle time of expensive equipment, reduction of expenses for maintenance and repair.

State-of-the art management systems are oriented onto supporting a competiveness of organizations and a continuous quality improvement of products, services and processes. One of essential elements of management is the risk management process which enables to manage uncertainty and risk in relation to the conducted activity by an organization. Managing risk assists organizations in setting strategy, achieving objectives and making informed decisions. Managing risk is part of governance and leadership, and is fundamental to how the organization is managed at all levels. It contributes to the improvement of management systems. A competent use of risk management mechanisms enables each organization to use its potential to a full extent and undertake proper decisions. The issues concerning a standardization of requirements in the case of standards from the management scope; in particular from the point of view of issues connected with risk management, are presented in the first part of the article. A model of the process, oriented onto a risk in the quality management system which enables to conduct managing activities in the situation of uncertainty and to take decisions oriented onto preventing mistakes in managing the organization and onto ensuring the appropriate quality, is described. The subject – matter concerning risk analysis, in particular from the point of view of meeting the EA Guidelines, concerning horizontal requirements related to the bodies assessing the conformity for notification purposes, is brought nearer. The most essential requirements, which must be met by such a body to guarantee a competent and impartial process of the product assessment, are described. In the following chapters the basic elements of the risk analysis process are discussed and an exemplary description of the risk assessment methodology is presented.

Drilling with a rotary steerable system, the mechanical drilling speed increases by two times compared to drilling with a screw bottom-hole motor, which provides significant savings drilling-time. The effective length of the horizontal elbow increases, which enables to increase the production rate more than twice. It is found that in comparison with the bottom hole motor, rotary steerable system provides drilling smoother barrel, which reduces the risk of accidents to come out. The dependence between the type of the bent housing and the most rational fields of its application is revealed, recommendations on the choice of the rotary steerable system for various issues of directional drilling are developed.

In order to reduce the number and time of layups and to increase the period of effective operation of a mechatronic system it is reasonable to carry out predictive recovery works during one stoppage (repair) for a group of component parts with equal, close or multiple operation hours to the prior-to-failure (limiting) state. Such approach gives also the possibility to carry out recovery works with separate elements in parallel, which allows to reduce the system layup time and to increase the production output.
