Perching with winged Unmanned Aerial Vehicles has often been solved by means of complex control or intricate appendages. Here, we present a simple yet novel method that relies on passive wing morphing for crash-landing on trees and other types of vertical poles. Inspired by the adaptability of animals' and bats' limbs in gripping and holding onto trees, we design dual-purpose wings that enable both aerial gliding and perching on poles. With an upturned nose design, the robot can passively reorient from horizontal flight to vertical upon a head-on crash with a pole, followed by hugging with its wings to perch. We characterize the performance of reorientation and perching in terms of impact speed and angle, pole material, and size. The robot robustly reorients at impact angles above 15{\deg} and speeds of 3 m/s to 9 m/s, and can hold onto various pole types larger than 28% of its wingspan in diameter. We demonstrate crash-perching on tree trunks with an overall success rate of 71%. The method opens up new possibilities for the use of aerial robots in applications such as inspection, maintenance, and biodiversity conservation.

The competition focuses on Multiparty Multiobjective Optimization Problems (MPMOPs), where multiple decision makers have conflicting objectives, as seen in applications like UAV path planning. Despite their importance, MPMOPs remain understudied in comparison to conventional multiobjective optimization. The competition aims to address this gap by encouraging researchers to explore tailored modeling approaches. The test suite comprises two parts: problems with common Pareto optimal solutions and Biparty Multiobjective UAV Path Planning (BPMO-UAVPP) problems with unknown solutions. Optimization algorithms for the first part are evaluated using Multiparty Inverted Generational Distance (MPIGD), and the second part is evaluated using Multiparty Hypervolume (MPHV) metrics. The average algorithm ranking across all problems serves as a performance benchmark.

Small Unmanned Aircraft Systems (sUAS) have gained widespread adoption across a diverse range of applications. This has introduced operational complexities within shared airspaces and an increase in reported incidents, raising safety concerns. In response, the U.S. Federal Aviation Administration (FAA) is developing a UAS Traffic Management (UTM) system to control access to airspace based on an sUAS's predicted ability to safely complete its mission. However, a fully automated system capable of swiftly approving or denying flight requests can be prone to bias and must consider safety, transparency, and fairness to diverse stakeholders. In this paper, we present an initial study that explores stakeholders' perspectives on factors that should be considered in an automated system. Results indicate flight characteristics and environmental conditions were perceived as most important but pilot and drone capabilities should also be considered. Further, several respondents indicated an aversion to any AI-supported automation, highlighting the need for full transparency in automated decision-making. Results provide a societal perspective on the challenges of automating UTM flight authorization decisions and help frame the ongoing design of a solution acceptable to the broader sUAS community.

Fox News chief national security correspondent Jennifer Griffin has the latest on the retaliation against the drone attack on U.S. servicemembers in Jordan on'Your World.' The White House stressed Friday evening that the United States is "not looking for a war with Iran," saying the retaliatory strikes carried out in Syria and Iraq were designed to "de-escalate" tensions and "put an end" to attacks on U.S. troops in the region. The United States began retaliatory strikes on more than 85 targets in Iraq and Syria against Iran's Islamic Revolutionary Guards Corps (IRGC) Quds Force and affiliated militia groups and proxies. The strikes come in response to the deaths of three U.S. service members last Sunday on a U.S. base in Jordan. White House National Security Council Coordinator for Strategic Communications John Kirby stressed that the United States is not seeking conflict with Iran or in the Middle East, but explained that the strikes that began Friday evening "will not end" tonight.

Fox News White House correspondent Jacqui Heinrich has the latest on the pressure on Biden to respond to the attack that killed three U.S. service members, on Special Report. President Joe Biden and First Lady Jill Biden will on Friday take part in the dignified transfer of the remains of three troops killed in the Iran-backed militia attack in Jordan last weekend. The Bidens will join the grieving families of the three American service members who died when a drone struck a base, known as Tower 22, near the demilitarized zone on the border between Jordan and Syria. The Iraqi border is only six miles away. The fallen troops were Sgt.

Referring to Thursday's attack, Ukrainian officials said another four people - including three foreign volunteers - were injured in a "massive" drone attack on the front-line town on the Dnipro River, about 60km (37 miles) north-east of the regional capital Kherson.

Joseph Votel discusses tensions in the Middle East and how the Biden administration could respond to a drone attack that killed three U.S. soldiers, on'The Story.' An Iran-backed militant group in Iraq has promised to continue attacks on U.S. troops after three American soldiers were killed by a drone strike in Jordan on Sunday. In a statement released Friday, Harakat al-Nujaba, one of the strongest Iraqi militias, announced that it plans to continue military operations against U.S. forces while allied factions have backed off their attacks after the Biden administration said there will be retaliation. Akram al-Kaabi, the group's leader, called for an end to the Israeli military operations in Gaza and withdrawal of the "American occupation of Iraq," in a statement posted on X. The announcement comes after Kataib Hezbollah, another powerful Iranian-backed Iraqi militia, which is closely monitored by the U.S. government, said on Tuesday that it would "suspend military and security operations against the occupying forces" to avoid embarrassing the Iraqi government.

The United States has approved plans for strikes in Iraq and Syria against multiple targets, including Iranian personnel and facilities, CBS News reported on Thursday, quoting US officials. President Joe Biden said on Tuesday that he had decided how to respond to a drone attack in northeastern Jordan near the Syrian border last Sunday, which killed three US service members and wounded more than 40. Sunday's attack was the first to result in the loss of American lives during the Israel-Hamas war. Here is what's known about the US plans: The US plans to retaliate against the drone attack on the US Tower 22 base near the border between Syria and Jordan by targeting Iranian personnel and facilities inside both countries. The Islamic Resistance in Iraq, believed to comprise multiple groups armed, funded and trained by Iran's Revolutionary Guards Corps, has claimed responsibility for Sunday's strike on the base. But on Wednesday, Kataib Hezbollah, the most powerful element in the force, announced the suspension of hostile operations against US troops.

Ukraine is deploying a nationwide electronic warfare system to confuse satellite navigation. Known as Pokrova, the system aims to prevent Russian missiles and drones from finding their targets and may already be in operation. It is likely to also affect satellite navigation for people in Ukraine. What does Ukraine's million-drone army mean for the future of war? The "spoofing" system interferes with GPS and other satellite navigation systems such as Russia's GLONASS and Europe's Galileo, collectively known as…

About three hours later, U.S. forces shot down an armed Houthi drone flying over the Gulf of Aden, Central Command said. About five hours after that, the military destroyed an explosives-laden naval drone that Central Command said was launched toward commercial ships and Navy vessels in the Red Sea. There were no injuries or damage reported in either incident. Finally, around 12:45 p.m., two anti-ship ballistic missiles were launched from Houthi-controlled territory, probably toward a Liberian-flagged, Bermuda-owned cargo ship, M/V Koi, in the Red Sea, Central Command said. The missiles landed harmlessly in the water.
