This new technology has evident social and economic impacts on our lifestyle and represents one of the most vital future trends [16]. In this context, Suab et al. have generally explained how different UAVs could be employed in forests and farming [7]. On the other hand, the mobility and flexibility of UAVs as well as their cheap costs represent their most powerful features for developing a new generation of cellular communication flying terminals as in [8][9][10], acquiring images rich of details for executing several geological applications as suggested in [11], or monitoring and tracking wildlife features [12]. Many engineers and researchers look at commercial multicopters as practical devices that could be adapted to perform a wide range of applications, even though they are unable to carry considerable payloads, and their batteries may sustain up to two successive flying hours if their maximal weight, including their payload, is around ten kilos. In such a case, building advanced types of flying robots that satisfy any special requirements regarding their payload or their maximal flying range requires new creative ideas. This paper presents a few novel designs with many technical details including computer vision systems and some modern AI-based algorithms that are required to perform smart missions. The organization of this paper is as follows: first, we present several recently designed and presented platforms for serving in different areas.

Tehran, Iran – Iran's army has unveiled a major underground base to showcase its aerial military capabilities in response to significant joint exercises by the United States and Israel. State television on Tuesday showed footage of a variety of fighter jets and military drones at the base, dubbed the "Eagle 44", the location of which remains unknown. It said the base is dug in the mountains to protect it from ammunition dropped from US strategic bombers that are capable of penetrating defences. The unveiling, which was attended by top military officials, comes less than two weeks after the US and Israel held their largest-ever joint drill, using thousands of troops and dozens of aircraft in addition to naval vessels and artillery systems in what was widely seen as a message to Iran amid rising tensions. That joint drill had in turn come days after Iran held wide-ranging exercises to showcase its military readiness.

TAIPEI – Taiwan will speed up development of drones for military use, taking into account the lessons of the war in Ukraine and the threat posed by China, the island's defense ministry said Tuesday. Unmanned aircraft have played a crucial role on both sides since Russia launched a full-scale invasion of Ukraine in February last year. Ukraine's defense minister has said that he regards drones as the future of modern warfare. Taiwan, which is facing a growing threat from China to use force to bring it under Beijing's control, has repeatedly said it is closely watching the war and learning lessons it could apply to fight off a Chinese attack, including how Ukraine has resisted a numerically-superior force. This could be due to a conflict with your ad-blocking or security software.

This work focuses on the study of tethered fights of a micro quadcopter, with the aim of supplying continuous power to a small-sized aerial robot. Multiple features for facilitating the interaction between a tethered micro quadcopter and a ground base are described in this paper. Firstly, a tether model based on the catenary curve is presented that describes a quadcopter tethered to a point in space. Furthermore, a method capable of estimating the tension applied to the quadcopter, based only on the inertial information from the IMU sensors and the motor thrusts, is presented. Finally, a novel method for localizing the quadcopter by exploiting the tension imposed by the tether and the shape of the tether is described. The proposed methods are evaluated both in simulation and in real world prototype.

This paper presents a two-step algorithm for online trajectory planning in indoor environments with unknown obstacles. In the first step, sampling-based path planning techniques such as the optimal Rapidly exploring Random Tree (RRT*) algorithm and the Line-of-Sight (LOS) algorithm are employed to generate a collision-free path consisting of multiple waypoints. Then, in the second step, constrained quadratic programming is utilized to compute a smooth trajectory that passes through all computed waypoints. The main contribution of this work is the development of a flexible trajectory planning framework that can detect changes in the environment, such as new obstacles, and compute alternative trajectories in real time. The proposed algorithm actively considers all changes in the environment and performs the replanning process only on waypoints that are occupied by new obstacles. This helps to reduce the computation time and realize the proposed approach in real time. The feasibility of the proposed algorithm is evaluated using the Intel Aero Ready-to-Fly (RTF) quadcopter in simulation and in a real-world experiment.

Officials had to close Mullaloo Beach in Perth, Western Australia, for the second time in a week on Monday, January 9, after a tiger shark was spotted swimming close to the shore. Check out this video, taken from a drone. A 16-year-old girl died after a shark mauled her while swimming in the Swan River in Australia, with only a teen diving in to save her as others watched in horror. "A female received injuries after being bitten by an unknown species of shark at approximately 3.35pm on Feb. 4 2023," the Department of Primary Industries and Regional Development (DPIRD) said of the incident. "DPIRD is working with WA Police and local authorities to coordinate responses. A DPIRD Fisheries vessel is on the water monitoring the area, and DPIRD officers are conducting land-based patrols."

A new $2.2 billion US arms package for Ukraine includes a new rocket-propelled precision bomb that could nearly double Kyiv's strike range against the Russians, the Pentagon said Friday. Pentagon spokesman Pat Ryder said the new package includes the ground-launched small-diameter bombs (GLSDB), a munition that can fly up to 150 kilometers (93 miles), which would threaten Russian positions and depots far behind the front lines. "This gives them a longer-range capability... that will enable them to conduct operations in defense of their country and to take back their sovereign territory," Ryder said. Ukraine had been asking the United States for munitions that can fly farther than the HIMARS rockets with an 80-kilometer (50-mile) range. The GLSDB potentially gives Ukraine forces an ability to strike anywhere in the Russian-occupied Donbas, Zaporizhzhia and Kherson regions, and the northern part of occupied Crimea.

After the last few years of nonstop growth, Apple reported revenue of $117.2 billion for its first fiscal quarter, which is five percent down year over year, marking the first time Apple's revenue has dipped since 2019. That said, the company set a revenue record of $20.8 billion in its Services business and hit over two billion active devices globally. CEO Tim Cook said three things hit revenue: the "challenging macroeconomic environment," foreign exchange issues and COVID-related supply constraints that led to delays in the ship times of iPhone 14 Pro and Pro Max models. Anecdotally, we've heard from several people that ended up canceling iPhone orders over lengthy delays. It reflects a slowdown across most of the tech industry, with a mixture of lower revenues, decreased profits and general growth slowdown across Meta, Microsoft and Google owner Alphabet.

An analysis of satellite images appears to show damage to an Iranian military facility in a drone attack last week, including holes in the building's roof, according to The Associated Press news agency. Cloudy weather had prevented satellite pictures of the site of the facility from showing the effect of the attack on January 28. While Iran has offered no explanation yet of what the facility in the city of Isfahan manufactured, the assault threatened to again raise tensions in the region, with Tehran blaming Israel for the drone attack, a conclusion that was also reached by United States officials. Video taken of the attack showed an explosion at the site after anti-aircraft fire targeted the drones, likely from one of the drones reaching the building's roof. Iran's military has claimed that it shot down two other drones before they reached the site.

The Texas Department of Public Safety say criminal organizations have increasingly turned to using drones to scout out areas for illegal immigration.
