Abstract
Drones are widely known for their mobility and ease of use and represent a significant technological breakthrough with various applications. In this paper, a novel inexpensive Search and Rescue (SAR)-based approach for application in indoor environments is presented. The usage of Bluetooth Low Energy (BLE) has been evaluated with respect to other technologies and a conceptual view of the complete setup has been presented. Besides the cost of the drone and the locator devices, the other hardware is relatively inexpensive costing only a fraction of a US dollar. The system is believed to cover a wide area in a small-time frame ranging a few minutes, for instance, a 3600m2 surface area could be scanned in less than 5 minutes. The system is tested by attaching a BLE device in the payload to evaluate the presence of target beacons. Potential upgrades in the system are also proposed, including design modifications for outdoor use and the application in locating missing objects. This system can confidently replace search parties dealing with missing children in public places or venues, with minimal human interaction while bearing the potential for complete automation.
Highlights
During the last decade, the usage of Unmanned Aerial Vehicles (UAVs) has risen exponentially [1]
One of the most significant applications of UAVs lies in the domain of Search and Rescue (SAR)-based missions
Data are transmitted in Bluetooth Low Energy (BLE) using two service profiles, namely Find Me Profile (FMP) and Proximity Profile (PXP), which take into consideration the slave/master positions
Summary
The usage of Unmanned Aerial Vehicles (UAVs) has risen exponentially [1]. One of the most significant applications of UAVs lies in the domain of Search and Rescue (SAR)-based missions Such operations are performed in conventional matters, which are time consuming and costly [5]. Some advances in the automation of the search process have been implemented which involve AI-based protocols to identify pre-trained objects or shapes, or face recognition In confined places, such as events held at parks, theatres, or concerts, parents or guardians that lose their children usually seek the assistance of a dedicated lost child office to locate them. This paper discusses a novel inexpensive approach of utilizing multirotor drones as a SAR tool whereby it scans passive pre-defined passive receivers This device overcomes the characteristic challenges of events being held in large venues, allowing object/person finding applications. These developments may be uploaded to upgrade the system for open space usage with certain limitations
