The process of developing a navigation system for an educational mobile robot is considered. The analysis of the existing navigation systems of mobile robots is carried out, the hardware of the navigation systems is presented, their advantages and disadvantages are shown. A diagram of the interaction of on-board subsystems during the autonomous movement of a mobile robot is presented. The design of the basic chassis of the educational mobile robot and its technical characteristics are described. A block diagram of the interaction of ROS packages (robotic operating system) for creating a terrain map using a laser ranger is developed, as well as a block diagram of the interaction of ROS packages for the an educational mobile robot tracing. Considering the studies, conclusions are drawn on the applicability of the proposed implementation of a laser ranger based navigation system for an educational mobile robot.

A brief review of the existing auxiliary prosthetic control systems was carried out. The concept of an intelligent prosthesis is proposed, which will expand the possibilities of application and simplify the use of the prosthesis. The required actions of the vision system in automatic and manual capture modes are considered. The sequence of operation of the subsystems of the technical vision system is determined. The possibility of implementing a prosthesis vision system based on neural network technology is shown. The method of using a ready-made neural network for recognition of objects by a prosthesis is considered. The possibilities of using the considered neural network technologies in the mathematical education of engineers are presented. A version of the prosthesis design is proposed. The possibility of constructing the described prosthesis is shown.
