Keywords: remote control, robotic technology, automated monitoring, automated systems.
In the modern world, information technologies are rapidly developing. They are being introduced into all spheres of human activity everywhere and even in the food industry. The fact is that modern trends in the informatization of society require new solutions and capabilities from automatic process control systems in the field of mobility and remote control. The development of such systems become relevant.
In view of the State Program "Digital Kazakhstan" for 2017-2020 [1], which was approved by the Government of the Republic of Kazakhstan No. 827 of 12/12/2017, the topic of the thesis is as relevant as ever. The state program "Digital Kazakhstan" was the basis in connection with the message of the President of the Republic of Kazakhstan Nursultan Abishevich Nazabayev "The Third Modernization of Kazakhstan: Global Competitiveness" dated January 31, 2017 [2].
Remote control is the transfer of a control action (signal) from an operator to a control object located at a distance, due to the inability to transmit a signal directly if the object moves, is at a considerable distance or in an aggressive environment, etc., [3,4, 5,6].Remote control systems differ primarily in the type of communication channel:
The importance of having an off-site controller is crucial when dealing with complex or multiple tasks associated with devices separated by large distances. The remote control system can control the object having degrees of freedom.
For the experiments, the remote control system, was designed layout in the form of the shirt front, which are shown in Figures 1 and 2.
Figure 1 - Scheme
Figure 2 - Three-wheeled platform Testing on the distance of the remote control system was carried out on the street, in a residential area. From the transmitter to the receiver was a direct visibility. After the tests, the distance from the transmitter to the receiver was calculated using Google maps.
The first test system for communication range. As shown in Figure 3, the communication range was 30 meters, which did not satisfy the requirements. During testing, errors were identified that needed to be corrected.
Figure 3 - The first test of the system for communication range The second testing system for communication range. Before testing, errors that were identified during the first testing were fixed. Namely, the capacitor on the radio module in the receiver was replaced with a capacitor with a larger capacity and the capacitor on the radio module was also soldered in the transmitter. Also the antenna on the radio module in the transmitter was replaced. As shown in Figure 4, the communication range was 130 meters, which did not correspond to the estimated 200 meters. This is probably due to the fact that there were interference on the frequency of Wi-Fi.

During the two tests, the unreliability of the receiver and transmitter design was revealed. Mounted installation did not guarantee trouble-free operation. During testing, the contacts opened and by itself, the design looked unreliable. Therefore, it was decided to remake the system[7,8].
Having studied the concept of remote control and the types of its communication channels, a radio frequency communication channel was selected. Since it is most suitable for the system of remote control of objects through wireless access. Also, having considered modern remote control solutions, a system of one receiver and one transmitter was created.
After analyzing various microcontrollers to build a system, the choice fell on the Arduino Uno board, based on the ATMega328p microchip. Due to the fact that it provides the user with a large selection of different modules for design and is easily programmed in the Arduino IDE. For the connection of two Arduino Uno boards, the nRF20L01 + module was used in connection with the best provision of price-performance ratio. Analog joysticks and potentiometers are selected for control. Having assembled the receiver and the transmitter, the code was written in the Arduino IDE for their firmware.
After the development of a physical model of a remote control system, it became necessary to test it, and for this purpose models were designed as a typewriter. The machine is designed to demonstrate the operation of the system for the transfer of instantaneous response to control objects.
Having completed the testing of the system, we can say that:
1. She showed herself well and has great potential. Using more expensive materials and modules can achieve a greater range of communication.
2. There is a need to replace the Arduino UNO board with the Arduino NANO on the receiver, which will make it more compact.
3. The scheme can be made more reliable by placing it on the board.
4. You can add a video camera to a managed object that will allow you to control it without direct visibility and record video.
In general, the system at the moment can be used in a wide range of different areas due to its versatility. It is also possible to remake it for a specific object, replacing or adding controls and slightly changing the code.
