When multiple drones are working together in the same airspace, perhaps spraying pesticide over a field of corn, there’s a risk they might crash into each other. To help avoid these costly crashes, MIT researchers presented a system called MADER in 2020. This multiagent trajectory-planner enables a group of

Researchers at the Faculty of Aerospace Engineering, Delft University of Technology, Kluyverweg 1, 2629 HS Delft, The Netherlands have recently published a paper proposing an airspeed instrument using microphones as airspeed sensors. Abstract This paper puts forward a novel design for an airspeed instrument aimed at small fixed-wing tail-sitter unmanned

Researchers in Hong Kong have published a paper demonstrating the utilization of self-rotation in UAVs to extend the sensor field of view (FoV) without consuming extra power. Abstract Uncrewed aerial vehicles (UAVs) rely heavily on visual sensors to perceive obstacles and explore environments. Current UAVs are limited in both perception

Electrification is seen as having an important role to play in the fossil-free aviation of tomorrow. But electric aviation is battling a dilemma: the more energy-efficient an electric aircraft is, the noisier it gets. Now, researchers at Chalmers University of Technology, Sweden, have developed a propeller design optimisation method that

How fresh are your data? For drones searching a disaster zone or robots inspecting a building, working with the freshest data is key to locating a survivor or reporting a potential hazard. But when multiple robots simultaneously relay time-sensitive information over a wireless network, a traffic jam of data can

Researchers from Bochum and Saarbrücken have detected security vulnerabilities, some of them serious, in several drones made by the manufacturer DJI. These enable users, for example, to change a drone’s serial number or override the mechanisms that allow security authorities to track the drones and their pilots. In special

A team of researchers at the Microsoft Autonomous Systems and Robotics Research Group including Sai Vemprala, Rogerio Bonatti, Arthur Bucker, and Ashish Kapoor has extended the capabilities of ChatGPT to robotics, and controlled multiple platforms such as robot arms, drones, and home assistant robots intuitively with language. Have you ever

A project for incorporating dead birds into flapping-wing drones might enable new ways of stealthily snooping on wildlife – and possibly spying on people for military purposes. “Instead of using artificial materials for building drones, we can use the dead birds and re-engineer them as a drone,” says Mostafa Hassanalian at

In recent years, global health security has been threatened by the geographical expansion of vector-borne infectious diseases such as malaria, dengue, yellow fever, Zika and chikungunya. For a range of these vector-borne diseases, an increase in residual (exophagic) transmission together with ecological heterogeneity in everything from weather to local human

Mississippi State University (MSU) has once again been tapped to lead a major uncrewed aircraft systems (UAS) research, testing and evaluation project on behalf of the U.S. Department of Homeland Security (DHS). Homeland Security’s Office of Procurement Operations, on behalf of the DHS Science and Technology Directorate (S&

Aerial robots can autonomously collect temporal and spatial high-resolution environmental data. This data can then be utilized to develop mathematical ecology models to understand the impact of climate change on our habitat. In case of the drone's malfunction the incorporated materials can threaten vulnerable environments. The recent introduction
