Autonomous landing of rotary wing type unmanned aerial vehicles is a challenging problem and key to autonomous aerial fleet operation. We propose a method for localizing the UAV around the helipad, that is to estimate the relative position of the helipad with respect to the UAV. This data is highly desirable to design controllers that have robust and consistent control characteristics and can find applications in search – rescue operations. AI-based neural network is set up for helipad detection, followed by optimization by the localization algorithm. The performance of this approach is compared against fiducial marker approach, demonstrating good consensus between two estimations

The technology of the fixed wing and the rotary wing unmanned aerial vehicles have been emerging and the applications have been focused widely to numerous regions. This paper focuses on some applications where we have tested our multicopter and in future the further improvement shall incorporate. Our main focus was to build an aerial Covid warrior considering mainly three different and useful applications particularly for remote village areas where many facilities are not always available. First application is the delivery of the medical supplies to the people in need. Second, use of the onboard speaker, which can relay valuable information during emergency or the valuable health related awareness remotely by respective department. And the third application is use of the sanitizer spray arrangement for the larger area disinfection. The prototype has been tested in a typical village area in different conditions and has provided required performance due to optimized design. This paper is to facilitate other users to explore the capabilities of the multicopters for any situations like we suggested with this project considering this pandemic.

This paper proposes an effective approach for modelling and assessing the risks associated with unmanned aerial vehicles (UAVs) integrated into national airspace system (NAS). Two critical hazards with UAV operations are considered and analyzed, which are ground impacts and midair collisions. Threats to fatalities that result from the two hazards are the focus in the proposed method. In order to realize ground impact assessment, a multifactor risk model is designed by calculating system reliability required to meet a target level of safety for different UAV categories. Both fixed-wing and rotary-wing UAVs are taken into account under a real scenario that is further partitioned into different zones to make the evaluation more precise. Official territory and population data of the operation scenario are incorporated, as well as UAV self-properties. Casualty area of impacting debris can be obtained as well as the probability of fatal injuries on the ground. Sheltering factors are not neglected and defined as four types based on the real scenario. When midair collision fatality risk is estimated, a model of aircraft collisions based on the density of civil flight in different regions over Chinese airspace is proposed. In the model, a relative collision area and flying speed between UAVs and manned aircraft are constructed to calculate expected frequency of fatalities for each province correspondingly. Truthful data with different numbers of UAVs is incorporated in the model with the expected number of fatalities after a collision is included. Experimental simulations are made to evaluate the ground impacts and midair collisions when UAVs operate in the NAS.
