The possibility of creating a computer control system for an unmanned aerial vehicle using remote cloud computing according to predefined scenarios from the user's desktop is investigated. For this, an experimental setup was created, which includes a quadcopter, a personal computer with the Windows operating system, an on-board computer Raspberry-3 with the Linux operating system, a Pi Camera V2 camcorder, and a Pixhawk autopilot. To model the control and transmission of video images the own control programs and photo pursuit on a computer Raspberry-3 in Python are recorded. Based on the obtained results, a model of unmanned aerial vehicle control from the desktop of the user's personal computer via the on-board computer without the use of a standard control panel and operator is proposed.

To solve the battery power supply problem with wireless sensor networks (WSNs), a novel bidirectional wireless charging system is proposed, in which an unmanned aerial vehicle (UAV) can fly to the WSNs to charge sensors through high-frequency wireless power transfer (WPT) and also obtain energy for its own battery in the same way. To improve the performance of the UAV bidirectional wireless charging system, a lightweight design is adopted to increase its loading capacity and working time. Moreover, the radii and the numbers of turns and pitches of coupling coils were designed and optimized on the basis of simulations and experiments. Experimental results show that the weight of optimized UAV coil was reduced by 34.45%. The power transfer efficiency (PTE) of the UAV coil to sensor coil increased from 60.2% to 74.4% at a transmission distance of 15 cm, while that of the ground transmitting coil to UAV coil increased from 65.2% to 90.1% at 10 cm.

The paper considers a new method of processing all the necessary surfaces of crops through the use of an unmanned aerial vehicle (UAV). At the moment, the processing of all surfaces of tall shrubs and individual sections of trees with spot spraying of a chemical liquid on a large agro-industrial scale is not possible due to the imperfection of modern methods of processing agricultural crops. The proposed agricultural unmanned aerial vehicle, due to spot cultivation of crops, is able to increase yields and bring additional profits to agricultural farmers. Ease of operation is the most important advantage of the proposed UAV, for the processing of crops using this UAV does not require special skills, as, for example, when operating agricultural aircraft and ground equipment. Depending on the type of crops and the characteristics of the local landscape, the proposed UAV for agricultural purposes will be spraying in the vertical direction (top to bottom) or at a given angle by changing the position of the lever and its further fixation on the boom, as well as processing in the horizontal plane. The degree of direct human participation in the control and management of the UAV is determined based on the choice of the mode of differential application of fertilizers and pesticides for a given area - stationary or dynamic. In an idealized system, a programmed electronic computer (ECM) in the form of a computer, capable of adjusting the flight and the introduction of chemical reagents in a constant mode, will assume the main role in controlling the movement by analyzing the readings of the instrument sensors. All this can be implemented in practice at the proper level with appropriate funding, and the results of such a project in the future will open a new stage in the sectoral processing of crops and pole crops.

Autonomous unmanned aerial vehicles are complex systems of hardware, software, and human input. Understanding this complexity is key to their development and operation. Information visualizations already exist for exploring flight logs but comprehensive analyses currently require several disparate and custom tools. This design study helps address the pain points faced by autonomous unmanned aerial vehicle developers and operators. We contribute: a spiral development process model for grounded evaluation visualization development focused on progressively broadening target user involvement and refining user goals; a demonstration of the model as part of developing a deployed and adopted visualization system; a data and task abstraction for developers and operators performing post-flight analysis of autonomous unmanned aerial vehicle logs; the design and implementation of DATA COMETS, an open-source and web-based interactive visualization tool for post-flight log analysis incorporating temporal, geospatial, and multivariate data; and the results of a summative evaluation of the visualization system and our abstractions based on in-the-wild usage.

Three Degree Of Freedom

This paper presents the design and implementation of systems for autonomous tracking, payload pickup, and deployment of a 1/10th scale RC vehicle via a UAV helicopter. The tracking system uses a visual servoing algorithm and is tested using open loop velocity control of a three degree of freedom gantry system with a camera mounted via a pan-tilt unit on the end effecter. The pickup system uses vision to control the camera pan tilt unit as well as a second pan tilt unit with a hook mounted on the end of the arm. The ability of the pickup system to hook a target is tested by mounting it on the gantry while recorded helicopter velocities are played back by the gantry. A preliminary semi-autonomous deployment system is field tested, where a manually controlled RC car is transported by a UAV helicopter under computer control that is manually directed to GPS waypoints using a ground station.

Magnetic nanoparticle heating in alternating magnetic field is the novel approach to the hyperthermia technique for cancer treatment. The accurate measuring of the specific heat absorption rate of the magnetic fluid is the critical issue in the search for efficient materials to minimize the concentration of the magnetic nanoparticles in human tissues. In this work the heat absorption measurement setup consisting of a system of the magnetic field generation, a temperature measuring system, a cooling system, and an external computer control system has been developed. The results of the calibration as well as the results of measurements on the cobalt ferrite nanoparticles are presented.

This project explored the feasibility of using video images acquired with an unmanned aerial vehicle (UAV) to obtain three-dimensional (3D) point clouds using structure from motion (SfM) software. Missions were flown using an Aeryon Scout: a lightweight, vertical take-off and landing quadrotor micro UAV with a miniature video camera. The initial mission captured urban scene images that were used to assess system performance while the main mission focused on rock walls where 3D images were used to successfully measure fracture orientations. Point clouds generated from this combination of technologies were sparse, but in the future, improvements in the resolution of original video images would cascade through the processing and improve the overall results. Such a system could have a multitude of applications in the mining industry, contributing to both safety and financial considerations.
