Charging Platform of Chess-Pad Configuration for Unmanned Aerial Vehicle (UAV)

Abstract

The authors of this study designed and optimized a charging landing pad system that mitigates the landing accuracy issues of unmanned aerial vehicles (UAVs). The study looks at the charging process, energy conversion during periodic landing on a unique platform, and an onboard and on-ground scheme design procedure. The circuit is fixed on the UAV platform and comprises six integrated bridge rectifier diodes to alter the four connection pin terminals’ charge polarity. The inclusion of a current indicator shows the flow of charge during successful docking. The charging platform consists of square conductive copper plates of specific dimensions that provide positive and negative polarity in a chess form to ensure the contact of various polarities. This design considers two power supply options: a solar panel and a standard mains supply. The contact point coordinate probability when landing is the crucial aspect of this design. A first version of the proposed system was implemented to measure its effectiveness for commercial drones. This system provides an automated recharge station with reliable performance. Numerical experiments showed that the system’s energy conversion remains efficient regardless of drone orientation over the platform or the environment’s nature.

A Decade of UAV Docking Stations: A Brief Overview of Mobile and Fixed Landing Platforms

“…There are solutions that consist of a landing pad with no positioning systems and only wireless charging for the battery, such as [31][32][33][34][35]. It is a great way to keep a UAV charged if long routes should be crossed, but it can also be used to keep a UAV charged with no additional equipment needed on the docking station.…”

Development of self-charging unmanned aerial vehicle system using inductive approach

“…To overcome the issue, many researchers have devoted their time to focus on the autonomous charging approach to increase the endurance and the overall flight time as given in [11], [12]. As highlighted in [10], Silverman et al [13] demonstrated the autonomous recharging on a charging dock for a ground robot and researchers in [14] proposed a battery swapping station approach for small co-axial helicopters.…”

“…As highlighted in [10], Silverman et al [13] demonstrated the autonomous recharging on a charging dock for a ground robot and researchers in [14] proposed a battery swapping station approach for small co-axial helicopters. The recent work on contact-based technique can be found in [11] which is able to improve the misalignment issue and also the efficiency of the system. However, despite of many results available in the framework of contact-based autonomous charging approaches, every of the results suffer from their own conservatisms.…”
