“…For the stable UAV flight, performing the listed flight modes, the flight controllers with software are used. In addition to the microcontroller, the gyroscope, accelerometer, barometer, magnetometer, and GPS receiver are installed on it [4][5][6]. The most common flight controllers are MultiWii, APM 2.x, Pixhawk, SPRacingF3, OMNIBUSF4V3, SPRacing F7 and others [6][7][8][9], that can be used open for firmware patching Ardupilot [2], cleanflight, INAV [9,10], betafight.…”

In this article, the budgetary unmanned aerial vehicles (UAVs) of the rotary type (the hexacopter, the quadcopter) based on flight controllers with ATmega2560, STM32F405 microcontrollers have been developed. A comparison is made of their capabilities, using the most popular firmware developed for them. The firmware was adjusted depending on the sensors, used in the flight controllers. The designed quadcopters, hexacopters are capable of performing the following flight modes. The holding horizontal -uses the gyroscope and the accelerometer. The maintaining a given altitude -uses a barometric sensor. The holding position -GPS receiver is additionally used. The returning to take-off mode and programmed flight along waypoints marked on the map before the UAV launch. A magnetometer is additionally used here. It has been experimentally established, that the hexacopter is more stable in thevflight compared to the quadcopter based on MegapirateNG ver.3.1.5R2 and ArduCopter 3.2.1 firmware. It has been shown, that for large quadcopters with frame sizes larger, than 450mm, INAV firmware is less preferable, than Ardupilot firmware. The built copters can be used for photo and video shooting of terrain with the radius of up to 3.5 km with lithium-ion cells with a capacity of 6000 mAh. They have the flight duration of 15-20 minutes and the average speed of 20 km/h.

“…Chloroplasts contain thylakoids (formations), which in turn form their spatial structure, various enzymes involved in the chemistry of plant uptake of CO2.In terms of chemical composition as a percentage of dry matter, most chloroplasts consist of proteins (30-60%), lipids (20-40%), DNA (0.01-0.02%), RNA (0.5 -3.5%). ), minerals (6-10%) and pigments -chlorophyll (5-9%), carotenoids (4-5%) [10]. A pigment is a compound (complex molecule) that absorbs light in the visible region of the spectrum (400-700 nm).…”

“…Several articles, performed by the authors of this paper [8,9], consider the possibility of remote sensing to control the quality of plants, their bacterial and fungal damage, exposure to stressful situations and more. Moreover, such means can be installed on the mobile intelligent devices, such as a helicopter [10,11]. However, these methods don't fully solve the problem, that sets in the paper.…”

In the article on the basis of the analysis of providing the population of the world with food, the task of creation of small-sized intellectual devices for express systems of control of conditions of development of food plants is set. Such control can be carried out both in laboratory conditions and in the on-line mode. The authors analyzed the known methods of tissue diagnostics of plants by sap, by lymph, by extract, etc. The methods used in the laboratory, first of all, as one of the advanced ones on the simulation of cellular modeling of photosynthesis in plant tissues are considered. Portable intelligent devices based on the method of chlorophyll fluorescence were created, its functional scheme was developed and a working model was developed, an application software package was developed. This allows on-line control of the impact on plants of stress factors, frost, drought, dehydration, the level of soil fertilizers, herbicides, biological additives, environmental pollution by harmful emissions, viral and bacterial loads. The effectiveness of research is shown.

“…They can be used for terrain research, rescue operations, in the work of fire services, military intelligence. Of particular interest are the vehicles with a fixed wing (the flying wing, the airplane) [2], that are more energetically economical compared to the quadrocopters and hexacopters [6,7], they fly over a greater distance with a higher speed. Therefore, with the same battery capacity and flight weight, they can explore an area 2-3 times larger in size, than the rotary-type UAV (quadcopter).…”

A budget (up to $100) unmanned aerial vehicle (UAV) of an aircraft type based on the OMNIBUSF4V3 flight controller with an STM32F405 microcontroller is developed in the article. The created aircraft performs the following flight modes: the holding altitude and position, the automatic return to the takeoff point on command from the control panel or in case of loss of communication with it, the automatic flight along a given trajectory. The possibility of the flying along the points of the designed aircraft with the firmware INAV ver.2.5.0 without using a barometer and magnetometer, that are necessary for the rotary UAV to perform a similar task, is shown. Using the Blackbox INAV 2.5.0 toolkit and the Google Earth Pro service, the real flight path of the aircraft, speed parameters, and flight altitude according to the readings of the GPS receiver were established. The heights and speeds of the aircraft passing the flight points have been experimentally determined. Their close correspondence was established to those values, that were programmatically entered into the aircraft flight controller before launch. The correspondence was established between the real flight path of the aircraft and the one entered into the flight controller using the configurator. The constructed aircraft can be used to perform photo and video surveys of the terrain in automatic mode with the route length of 6-8 km, using a lithium polymer battery with a capacity of 1800-2200 mAh.
