In this paper, we propose a novel haptic device consisting of a Parrot quadcopter AR Drone 2.0 that delivers force-feedback to users when they press on the surface of the drone in the vertical direction. This drone haptic device will free users from any cumbersome devices which were utilized in previous haptics systems and allow them to sense kinesthetic feedback coming from the drone which in turn renders computer graphic objects, for example, a virtual box. Specifically, this system performs damped harmonic oscillation force motion on users’ hands and fingers. The oscillation function is implemented on the drone whenever users nudge the drone down. Overall, we evaluated the system with ten subjects, and results show the effectiveness of using damping oscillation motion to provide force-feedback delivered from the drone.

The paper considers the problem of protection of control of the radio signal of control of unmanned aerial vehicles as a task of control of signal parameters. The problem of control of a parameter of a radio signal and a problem of protection against interception by control of the unmanned aerial vehicle is formulated. The methods of estimating the parameters of the radio communication signal are analyzed and the method of estimating the parameters based on the method of maximum likelihood is proposed. This technique is demonstrated by estimating the phase of harmonic oscillation, which describes the radio signal and there are noise interference. Simulation modeling of the developed method is carried out, which confirmed the adequacy of the proposed model.

This new and efficient photogrammetric method for unmanned aerial vehicles (UAVs) requires only a few images taken in the vertical direction at different altitudes. The method includes an original relative orientation procedure which can be applied to images captured along the vertical direction. The final orientation determines the absolute orientation for every parameter and is used for calculating the 3D coordinates of every measurement point. The measurement accuracy was checked at the UAV test site of the Japan Society for Photogrammetry and Remote Sensing. Five vertical images were taken at 70 to 90 m altitude. The 3D coordinates of the measurement points were calculated. The plane and height accuracies were ±0.093 m and ±0.166 m, respectively. These values are of higher accuracy than the results of the traditional photogrammetric method. The proposed method can measure 3D positions efficiently and would be a useful tool for construction and disaster sites and for other field surveying purposes.

Control Layer

In this study, we propose a distributed swarm control algorithm for an agricultural multiple unmanned aerial vehicle system that enables a single operator to remotely control a multi-unmanned aerial vehicle system. The system has two control layers that consist of a teleoperation layer through which the operator inputs teleoperation commands via a haptic device and an unmanned aerial vehicle control layer through which the motion of unmanned aerial vehicles is controlled by a distributed swarm control algorithm. In the teleoperation layer, the operator controls the desired velocity of the unmanned aerial vehicle by manipulating the haptic device and simultaneously receives the haptic feedback. In the unmanned aerial vehicle control layer, the distributed swarm control consists of the following three control inputs: (1) velocity control of the unmanned aerial vehicle by a teleoperation command, (2) formation control to obtain the desired formation, and (3) collision avoidance control to avoid obstacles. The three controls are input to each unmanned aerial vehicle for the distributed system. The proposed algorithm is implemented in the dynamic simulator using robot operating system and Gazebo, and experimental results using four quadrotor-type unmanned aerial vehicles are presented to evaluate and verify the algorithm.

Nowadays, the creation of remotely-piloted aerial vehicles for various purposes is regarded as one of the most relevant and promising trends of aircraft development. FAU "25 State Research Institute of Chemmotology of the Ministry of Defense of the Russian Federation" have studied the operation features of aircraft piston engines and developed technical requirements for motor oil for piston four-stroke UAV engines, as well as a new engine oil M-5z/20 AERO in cooperation with NPP KVALITET, LLC. Based on the complex of qualification tests, the stated operational properties of the experimental-industrial batch of M-5z/20 AERO oil are generally confirmed.
