Researchers at EPFL have designed acoustic cavities that convert sound waves into thrust, propelling small robots and ultralight aerial vehicles without on-board actuators or electronics. These devices utilize hollow structures to harness specific frequencies of sound waves, generating directional thrust and controlled motion.
Researchers developed a disturbance observer to compensate for external disturbances, allowing the robot to reject disturbances while maintaining stable flight. The approach reduced the X-axis position error by 53.1% and improved overall stability.
Northwestern University engineers created a drone called Phantom Twist that harnesses motion blur to blend into its surroundings. The drone spins up to 25 times per second, making it difficult for humans to see clearly, and can potentially monitor wildlife or inspect infrastructure with less disruption.
A new open-source trajectory-planning system, MIGHTY, has been developed by researchers at MIT and the University of Pennsylvania. The system enables robots to generate smooth flight paths while reacting to obstacles in real-time, making it suitable for applications such as search-and-rescue, last-mile delivery, and industrial inspection.
Florida International University researchers have developed a defensive system called SHIELD that can detect and neutralize cyberattacks on drones in real time. The system allows the drone to finish its mission while providing robust recovery mechanisms, making it crucial for securing commercial drone use across industries.
Researchers are using bird flight insights to create drone systems that can save energy and fly more efficiently. The goal is to develop technology that can dramatically reduce the amount of energy required for uncrewed aircraft, enabling longer flights.
A quadrotor UAV-based smoke detection system using YOLOv8 nano model achieves 95% precision and 88.5% recall in detecting early-stage wildfires, making it a timely, scalable, and cost-effective method to combat wildfires. The system addresses global ecosystem threats and offers a rapid response to emerging fire threats.
The EPFL researchers built a drone with birdlike legs that can walk, hop, and jump into flight, greatly expanding the potential environments for unmanned aerial vehicles. The design allows it to take off autonomously in previously inaccessible environments.
Researchers in Italy have successfully monitored invasive stink bugs using drones and AI, reducing disruption and improving data capture. The system achieved a 97% detection accuracy, enabling precise forecasting models for integrated pest management strategies.
A team of researchers from Shibaura Institute of Technology developed a self-folding origami gripper that can be mounted onto drones, enabling them to grasp and hold objects. The gripper weighs only 5 grams but demonstrates grasping force equivalent to holding a 130-gram object.
Researchers at University of Missouri are developing software that allows drones to fly independently, perceiving and interacting with their environment while achieving specific goals. This technology has the potential to assist in mapping and monitoring applications, such as 3D or 4D advanced imagery for disaster response.
Scientists at EPFL have developed a method for a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks and enable robots to recharge using solar energy.
A Washington State University research team developed a system using cameras and small drones to detect and deter pest birds. The system successfully reduced bird counts by four-fold in vineyards, resulting in a 50% reduction in damaged fruits. Further refinement and industry partnerships are needed for commercialization.
Researchers at MIT have developed a new fabrication technique that enables the creation of soft actuators with 75% lower voltage requirements and 80% more payload capacity than current versions. This breakthrough could lead to the development of flying microrobots with improved performance and payload capabilities.
Researchers from The University of Tokyo Institute of Industrial Science have found that drones can be used as communication bases with underwater robotic devices (AUVs) for ocean surveys. UAVs offer high-speed observations, mobility, and resistance to ocean currents, making them suitable candidates for this application.
