TL;DR: In this article , an autonomous battery-changing system for UAVs using the theory of inventive problem solving (TRIZ) and user-centered design (UCD) methods is proposed.
Abstract: Unmanned aerial vehicles (UAVs) lifelong flight is essential to accomplish various tasks, e.g., aerial patrol, aerial rescue, etc. However, traditional UAVs have limited power to sustain their flight and need skilled operators manually control their charging process. Manufacturers and users are eagerly seeking a reliable autonomous battery-changing solution. To address this need, we propose and design an autonomous battery-changing system for UAVs using the theory of inventive problem solving (TRIZ) and user-centered design (UCD) methods. For practical application, we employ UCD to thoroughly analyze user requirements, identify multiple pairs of technical contradictions, and solve these inconsistencies using TRIZ theory. Furthermore, we design an autonomous battery-changing hardware system that meets user requirements and realizes the battery change process after the automatic landing of UAVs. Finally, we conduct experiments to validate our system’s effectiveness. The experimental results show that our battery-changing system can implement the autonomous battery-changing task, and our system has high efficiency and robustness in the real environment.

TL;DR: In this article, a novel numerical coupling model was developed to simulate the interaction between the fluid and the semi-active power generator, and the effects of time asymmetric pitching on the energy extraction performance of the generator was analyzed.
Abstract: Inspired from the bird and insect’s flight in nature, the time asymmetric pitching motion is proposed for the semi-active flapping wing power generator instead of conventional time symmetric pitching motion to seek better energy extraction performance. The NACA0012 wing, with prescribed pitching motion, is employed to represent as a power generator, where the vertical hydrodynamic force activates its heaving motion. A novel numerical coupling model is developed to simulate the interaction between the fluid and the semi-active power generator, and the effects of time asymmetric pitching on the energy extraction performance of the generator is analyzed. It is found that the time asymmetric pitching motion has a noticeable effect on the energy extraction performance of the generator, as it affects the instantaneous energy coefficient, energy efficiency and the flow structures. It is also concluded that with an optimal time asymmetric pitching motion, the maximal efficiency increases as high as 17% over the time symmetric pitching power generator.
TL;DR: In this paper, the effects of flexibility, kinematic motions, and two-to-six-wing flapping configurations on the FMAV through numerical simulations were investigated, and it was shown that a rigid spanwise and flexible chordwise wing produces the highest lift with minimum power.
