UAV's are becoming popular for various object search applications in agriculture, however they usually use time-consuming row-by-row flight paths. This paper presents a deep-reinforcement-learning method for path planning to efficiently localize objects of interest using UAVs with a minimal flight-path length. The method uses some global prior knowledge with uncertain object locations and limited resolution in combination with a local object map created using the output of an object detection network. The search policy could be learned using deep Q-learning. We trained the agent in simulation, allowing thorough evaluation of the object distribution, typical errors in the perception system and prior knowledge, and different stopping criteria. When objects were non-uniformly distributed over the field, the agent found the objects quicker than a row-by-row flight path, showing that it learns to exploit the distribution of objects. Detection errors and quality of prior knowledge had only minor effect on the performance, indicating that the learned search policy was robust to errors in the perception system and did not need detailed prior knowledge. Without prior knowledge, the learned policy was still comparable in performance to a row-by-row flight path. Finally, we demonstrated that it is possible to learn the appropriate moment to end the search task. The applicability of the approach for object search on a real drone was comprehensively discussed and evaluated. Overall, we conclude that the learned search policy increased the efficiency of finding objects using a UAV, and can be applied in real-world conditions when the specified assumptions are met.

Ukraine's air defences shot down 58 of 132 Russian drones, the Ukrainian air force said. It said 72 Russian drones were "lost" due to the use of electronic warfare interference tactics. There were no immediate reports of damage.

New Jersey State Sen. Jon Bramnick joins'Cavuto Live' to discuss his call for a limited state of emergency over unanswered questions about alleged drone sightings. U.S. national security officials appeared to dispel concerns about the mysterious drones flying over the Northeast in a recent call with reporters, one going as far as describing nationwide uneasiness as "a slight overreaction." The call, attended by Fox News Digital Saturday, was hosted by senior Biden administration officials, including representatives from the FBI, the Federal Aviation Administration (FAA), the National Security Council (NSC), the Department of Homeland Security (DHS) and the Department of Defense (DOD). The senior officials remained tight-lipped about the origins of the drones, which are still being investigated. The mysterious aircraft were first spotted flying above northern New Jersey in mid-November and have been repeatedly seen by thousands of residents over the past few weeks.

Large Language Models (LLMs) are transforming the robotics domain by enabling robots to comprehend and execute natural language instructions. The cornerstone benefits of LLM include processing textual data from technical manuals, instructions, academic papers, and user queries based on the knowledge provided. However, deploying LLM-generated code in robotic systems without safety verification poses significant risks. This paper outlines a safety layer that verifies the code generated by ChatGPT before executing it to control a drone in a simulated environment. The safety layer consists of a fine-tuned GPT-4o model using Few-Shot learning, supported by knowledge graph prompting (KGP). Our approach improves the safety and compliance of robotic actions, ensuring that they adhere to the regulations of drone operations.

New Jersey State Sen. Jon Bramnick joins'Cavuto Live' to discuss his call for a limited state of emergency over unanswered questions about alleged drone sightings. President-elect Trump on Saturday seized on the mysterious drone controversy in New Jersey to mock one-time ally turned nemesis Chris Christie. The president-elect, who will take office in just over a month, shared an artificially generated meme of the former New Jersey governor eating McDonald's with more McDonald's meals being delivered by drones, mocking his weight on Truth Social and X. Christie endorsed Trump in 2016 but was later axed as the head of his transition team. Last year, Christie had a short-lived presidential campaign for the 2024 election during which he called Trump a "coward" and a "puppet of Putin," but he dropped out in January. President-elect Trump on Saturday seized on the mysterious drone controversy in New Jersey to mock one-time ally Chris Christie.

President-elect Donald Trump wants to create an Iron Dome missile shield over the United States. Can this really be happening without our government's knowledge. Let the public know, and now. Otherwise, shoot them down!!!" he wrote Friday on Truth Social. Couldn't agree more, except please don't get your shotgun out of the closet and start rooting around for a box of shells. It's illegal to interfere with any aircraft in flight, manned or unmanned. Maybe its deer season where you live, but alas, it is never drone season. Right now, statutes limit even the military's ability to intercept drones in the U.S. America's got a drone problem. Some drones are legal and no threat to you and me. Some are flown by drug cartels dropping off fentanyl in San Diego. Gen. Greg Guillot, Commander, U.S. Northern Command, told the Senate more than 1,000 drones per month cross the southern border. Other drones belong to the police, or to the military. Don't forget the NYPD has 110 drone operators qualified by the FAA. I also expect some of the drone sightings connect to military experiments and operations. Map showing some of the places where mystery drones have been spotted in Northeastern USA in December 2024. But without question, the U.S. is vulnerable to a national security threat from drones in a way we've never experienced before. While many U.S. military installations have anti-drone systems, the rest of the country doesn't. A new plan for countering drones in U.S. airspace should be top priority for President-elect Trump's incoming Cabinet: Homeland Security, Defense, and Transportation, with the FAA. Find a conference table at Mar-a-Lago and get key Cabinet nominees Kristi Noem, Pete Hegseth and Sean Duffy started now. What worries me is the pattern emerging of sightings of multiple drones, operating at low altitude, with persistent and coordinated overwatch, near military bases and critical infrastructure. Of course, New Jersey has a lot of cool stuff: the aircraft carrier electromagnetic catapult test infrastructure, Picatinny Arsenal, Naval Weapons Site Earle, which stores and loads munitions for the Navy's Atlantic fleet. While the New Jersey sightings date from Nov. 20, drone incidents started years ago. Back in 2017, an Air Force F-22 Raptor stealth fighter encountered a drone over the runway while landing at Langley AFB in Virginia. Yeah, I can see why the Chinese might want a close-up view of the engine intakes and stealth panel seals on that. In California, drones regularly drop inside the fences at the sprawling factories in Palmdale that build top secret military planes like the B-21 stealth bomber. "Some of it, I'm pretty sure, is our adversaries.

New Jersey State Senator John Bramnick joins'Cavuto Live' to discuss his call for a limited state of emergency over unanswered questions about alleged drone sightings. A New Jersey state Senator is calling on Gov. Phil Murphy to declare a state of emergency to ground all drones as a way of getting to the bottom of ongoing reports of unmanned craft swarming the Garden State in recent weeks. State Sen. Jon Bramnick, a Republican, told "Cavuto Live" on Saturday that he also wants the FAA to join in the state of emergency as the public becomes increasingly frustrated with a lack of answers as to what is going on in the skies. Bramnick says he has contacted Murphy about enacting a state of emergency but has not gotten a response. State Sen. Jon Bramnick is calling for a limited state of emergency due to mysterious drone sightings.

At least nine people have been killed and 20 others injured following a drone strike that hit a hospital in the city of el-Fasher in Sudan's northern Darfur region. The Federal Ministry of Health blamed the paramilitary Rapid Support Forces (RSF) for the attack, which took place on Friday. Officials say the group fired four rocket-propelled grenades towards the city's main healthcare facility. A resistance committee in el-Fasher, involved in relief efforts, said the attack targeted the Saudi hospital, forcing it to suspend medical services. It was the last remaining open hospital in the city.

Former Republican Gov. Larry Hogan of Maryland said Friday that he personally witnessed "dozens of large drones" flying above his home on Thursday evening. Former Republican Gov. Larry Hogan of Maryland has said that he personally witnessed "dozens of large drones" flying above his home in Davidsonville, Maryland, on Thursday evening as the mystery surrounding the various unexplained sightings continues. "Last night, beginning at around 9:45 pm, I personally witnessed (and videoed) what appeared to be dozens of large drones in the sky above my residence in Davidsonville, Maryland (25 miles from our nation's capital)," Hogan wrote on X Friday. "I observed the activity for approximately 45 minutes." The former governor said he does not know if these drone sightings are evidence of a threat to public safety or national security, but he called out the federal government for a "complete lack of transparency" in the face of Americans' concerns.
