Swiss drone crashes near children, forcing suspension of delivery program
In May, a 22-pound Swiss Post drone crashed 50 yards away from a group of children. As a result, the drone delivery program in Switzerland has been suspended indefinitely. Swiss Post has asked Matternet to make several changes to the system: parachutes connected to the UAV by two ropes instead of one, ropes reinforced with metal braiding, and a louder emergency landing whistle.
Fault Diagnosis of Drone Propellers Using AI
Propeller defects in drones can cause them to fall from the sky and researchers have used different methods to perform fault diagnosis. But a new study by Italian researchers takes a different approach and focuses on measuring the noise emitted by the drone. Different noise patterns are used to build an artificial intelligence (AI) model that detects unbalanced blades in a UAV propeller. See Fault Diagnosis for UAV Blades Using Artificial Neural Network.
Drones Chasing Drones Using Deep Learning and AI
A Canadian study proposes target-detection and target-following using AI techniques for UAV pursuit-evasion. Deep reinforcement learning predicts the actions to apply to the follower UAV to keep track of the target UAV. A deep object detector and a search area proposal predict the position of the target UAV for tracking purposes. The proposed framework uses vision data. See Drones Chasing Drones: Reinforcement Learning and Deep Search Area Proposal.
The amazing world of nano drones
Nano drones have been studies for several years. Draper Lab’s DragonflEye drone project was announced in 2017. A real dragonfly wears a tiny backpack fitted with electronics, sensors, and a solar cell. AeroVironment has been working on a nano-hummingbird since 2011. The market for the nano drones alone is expected to reach $13.4 billion by 2023.
If one drone isn’t enough, try a drone swarm
Drones are being used for precision agriculture, but there are shortcomings with one drone and a big farm. Many battery changes may be required and the survey could take a lot of time. The Norwegian Defence Research Establishment and Rajant Corporation in the US are working on a drone swarming approach with decentralized communications, self-organizing drones, and little human supervision. The technology uses Rajant’s “Kinetic Mesh®” radio technology and “foreign function interface” distributed computing software.
Atlas Multi-Drone System Used by Rio Military Police to Secure Soccer Tournament
Atlas Dynamics partnered with the Military Police of Rio de Janeiro State to use the AtlasPRO at the Copa America soccer (football) tournament. The AtlasPRO was flown in single and multi-UAS missions along the perimeter of the stadium during the tournament’s final series. Data was gathered on public safety hazards and to facilitate emergency response. This was the first time the Atlas mesh multi-drone UAS technology was approved for use at a major sporting event. The mesh multi-node communication capability allows a single operator to command and control a drone network from a unified ground control system. The operator can divide missions among several UAS and maintain constant “eyes in the sky” using autonomous hot-swap capabilities.
Report: Data Management a Challenge for Public Safety UAS Programs
Droneresponders has released the 2019 Mid-Year Public Safety UAS Report. Three out of four public safety agencies say they are already either operating drones or working on implementing a drone program. More than 80% of public safety UAS operators either have obtained or are pursuing, their FAA Part 107 certification. 82% of public safety agencies with a UAS program are operating multi-rotor systems, while only 11% are using fixed- or delta-wing drones. Over 35% of public safety UAS programs are using the FAA’s LAANC system for airspace requests.
UAS Used For Part 77 Airport Inspections in Washington
AeroTEC has completed proof-of-concept aerial surveys in Washington State at Sunnyside Municipal Airport (1S5) and Prosser Airport (S40). The AeroTEC system looks for runway obstacles using photogrammetry to meet the requirement of FAA FAR 14 CFR Part 77. See AeroTEC Conducts First UAS Part 77 Survey of Washington State Airports for WSDOT.
