The effects of the ground on propeller noise have been measured experimentally for the very first time by researchers in the Aeroacoustics research team at the University of Bristol. In findings, published in the Journal of Sound and Vibration, the team found clear differences in the noise characteristics of propellers
Research
A team of marine biologists affiliated with several institutions in the U.S., working with a colleague from Mexico, has found that it is possible to use drones to affix suction cup tags to whales as an alternative to doing it manually. In their study, reported in the journal Royal
Research
Researchers at Arizona State University unveiled a look at the SoBAR Drone, which is an experimental iteration of a classic drone that is highlighted by its inflatable body. Due to this structure, the drone is able to bounce off of obstacles and even cling onto them depending on the circumstance.

Inspired by the adaptable nature of organic brains, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have introduced a method for robust flight navigation agents to master vision-based fly-to-target tasks in intricate, unfamiliar environments. The liquid neural networks, which can continuously adapt to new

In an article recently published in the journal Solar Energy, researchers discussed the enhancements of photovoltaic (PV) receivers in laser wireless power transmission (LWPT) by using non-imaging optics. Laser Wireless Power Transmission (LWPT) In the area of wireless energy transmissions, such as space control in orbit, spacecraft sensor networks,

A new study published in PLOS ONE tests the performance of UAV-based observation techniques in measuring pedestrian activity in two comparative settings in Santiago de Chile. Objective observation of pedestrian behavior on the street has traditionally been difficult due to the intensive commitment of time and resources to spatial

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

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-
Research
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

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

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
Research
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
