“…In former cases, the hook needed a rigorous design, ensuring both adequate adaptability with respect to the target and adequate strength to support the imposed weight. Typically, the Ramshorn hook has been used for cranes that lift heavy loads [26]. Due to this, many industrial applications have widely used the hook [27].…”

The rapid development of unmanned aerial vehicles (UAVs) has helped expand their practical use to many industrial applications. However, UAVs sometimes suffer from a flight time limitation and/or a loss in communication. Such undesired malfunctions can endanger public safety and incur economic losses. This paper presents a new class of UAV that can retrieve a disabled or malfunctioned UAV from the ground. We developed a deployable hook retrieval system (DHRS) which integrates three principal mechanisms (i.e., deployment, slider-linkage-release, and hook release). Each mechanism plays a role in deploying and retrieving multiple hooks while using a simple control strategy. Through a Finite Element Method simulation, the hook was topologically optimized in order to achieve a high strength while reducing weight. The deployed multiple hooks allow the device to capture the target regardless of its orientation. Due to these design strategies, object recognition using a computer vision was simply demonstrated by exploiting ORB and FLANN algorithms. Through an experimental study, we discussed the target range, success rate, and the practical uses that the DHRS could achieve. The results show that the proposed designs were versatile and consistently successful in capturing the targets while addressing constraints such as power consumption, computational load, and lack of prior knowledge or information about the target.

The development of topology optimization (TO) methods gives designers new capabilities. A variety of TO techniques have recently been used in special circumstances to expand the capabilities of generalist techniques on particular niche issues. To achieve more flexible solutions and generalized procedures for most of the problems, hybrid methods are in trend. Hence, in this study, a different application of the Density-Shape-Element Removal method (D-S-ER) has been used to reduce maximum stress while also significantly reducing the weight of the structure, a lifting hook. A raw model was taken into consideration for the procedure. The study's findings show that the suggested strategy can be employed to provide quick and effective solutions by means of optimizing the balance between weight and strength. One of the findings depicts that combining different methods could give flexibility even in well-proven geometry optimization, which is the lifting hook in this study.
