Special drone collects environmental DNA from trees

If you want to find out what creatures live in an area, you can observe them or you can collect the “environmental DNA” they leave. Examples of external DNA include dead skin or feathers, waste, and fluids. These can be found in the soil, in water, or on rocks and tree branches. Collecting environmental DNA can be difficult and expensive. It can be unsafe if you have to climb up into the forest canopy to get the DNA samples

Now a special drone is being developed that can autonomously collect samples on tree branches. Collaborating are ETH Zurich, the Swiss Federal Institute for Forest, Snow and Landscape Research WSL, and environmental DNA (eDNA) specialist Spygen. (A French biotechnology company created in 2011 and specializing in molecular ecology.) The drone lands on a branch and adhesive strips collect the samples. DNA is extracted in the lab.

Efficiency of flapping drones to be increased with wing-folding research

A recent study led by Lund University in Sweden found that birds fly more efficiently by folding their wings during the upstroke. This might have implications for flapping drones and could increase their propulsive and aerodynamic efficiency. In order to study the different ways that wings could flap, the research team constructed a robotic wing that can flap the way birds do but can also flap in ways birds don’t. Wind tunnel measurements record the performance of the wing. Biology researcher Christoffer Johansson says “Flapping drones could be used for deliveries, but they would need to be efficient enough and able to lift the extra weight this entails. How the wings move is of great importance for performance, so this is where our research could come in handy,”

Bill Outlawing Flying Drones Over Prisons Soars Through Wyoming Senate

The Wyoming Department of Corrections says just two incidents have occurred in Wyoming that involve drones and prisons. (Those were attempts to deliver tobacco.) But other prisons have seen drone incidents. The Wyoming Corrections Director fears that drones could be used to spy on prisons and identify guards, inmates, and specific facility details. After the Senate vote, the legislation goes to the state House.

It Looked Like A Nice Family Home. Cops Suspect It Was A Secret Drone Airport For MDMA Dropoffs

Nobody seemed to live there at the $650,000 property in upstate New York. The grounds were unkempt and expensive-looking cars came and went. Law enforcement decided to investigate and border patrol came up with a surveillance tool that could “recognize drone signatures, map their flight path, and identify starting and stopping points via GPS.” At night, a UAV flew in. Police arrived and the pilot and two others were taken into custody. The drone held a package with $110,000 (street value) of MDMA, 3,4-Methylenedioxymethamphetamine, commonly called Ecstacy. At this time, only the alleged drone pilot has been charged.

Ex-Amazon drone manager says he was fired for raising safety concerns

The former manager is suing Amazon in King County Superior Court in Seattle, claiming racial discrimination in promotions and retaliation for raising safety concerns. He notes the lack of safety protocols in drone testing, the large number of crashes, and restrictions on employee access to flight information, videos, and pictures.
The man is seeking lost earnings, and compensation for legal fees and emotional distress. Amazon said in a statement “these allegations are false and we look forward to proving that in court.” See also, Amazon Drone Crashes Hit Jeff Bezos’ Delivery Dreams.

Use of drones, robotic dog in NY police intervention spark debate

Federal agents flew a UAV into a Poughkeepsie, NY apartment while executing a search warrant. Video from the drone showed the suspect throwing a handgun out of a window. He was arrested and booked on illegal possession of a firearm. NYC lawyer Albert Fox Cahn said, “Flying drones in public air space is invasive enough, but using it inside of a person’s home is completely unconstitutional.”

We used drones to track the feeding habits of seabirds – new research

Foraging habits of seabirds were examined in a new study, A bird’s-eye view on turbulence: seabird foraging associations with evolving surface flow features. Feeding in turbulent water is difficult to study, but a DJI Phantom 3 quadcopter was able to track three species of surface-foraging terns and use particle image velocimetry to map the water vortices and upwellings.

The Dog Poodemic Is Here. Call in the Dung-Hunting Drones

The lockdown gave people an excuse to buy that puppy they always wanted, but owners are hanging the bags of poo in trees and on bushes. Using image recognition, drones might be useful for finding the bags and notifying authorities. (No, we didn’t make this up.)

Bird-like robots could assist in medical emergencies and hunt down drones

Uncrewed aerial vehicles (UAVs) can draw their inspiration from the biological world. The GRIFFIN project from the University of Seville is seeking to create prototypes of highly autonomous, ultra-lightweight robot birds. They would minimise energy in flight by soaring and flapping.

The government’s been worried about DJI drones — the Pentagon now says they’re safe

FAA Announces Effective Dates for Final Drone Rules

The final rules go into effect on April 21, 2021, that require remote identification of drones, allow some flights over people and moving vehicles, and permit flights at night under certain conditions. Before flying under the new provisions a remote pilot must pass the updated initial knowledge test or complete the appropriate updated online training course.

RaceDayQuads LLC v. FAA (Lawsuit Challenging Drone Remote Identification Regulations)

RaceDayQuads (RDQ) filed a lawsuit against the FAA in Federal court. They believe some provisions of the Remote ID rule will have “devastating effects on our hobby and on all of RC flight.”

“This case is about protecting the constitutional rights and freedom to fly of millions of active drone and model aviation hobbyists by upholding the rule of law through challenging the FAA’s illegal law in court.”
“RDQ and Tyler Brennan are defending our constitutional rights and freedom by confronting the FAA’s rulemaking as violating multiple constitutional protections and rampant with unlawful arbitrary and capricious decision making, some of which was done intentionally behind closed doors out of the eyes of the public. Everyone is under the rule of law -including the FAA. The FAA is not free to differ from what the law requires.”
RaceDayQuads Press Release

Specifically, “RDQ’s goal is to allow current and future drone and model aviation hobbyists to continue flying safely:

without the need to broadcast their information
or be inhibited by any regulation which fails to comply with constitutional protections,
fails to follow rulemaking procedures,
fails to listen to the comments of those the rule would affect,
is founded upon inaccurate risk assessments and data,
or fails to provide an overall benefit to the American people.”

The Petition for Review was filed in the United States Court of Appeals for the District of Columbia Circuit on March 12, 2021. RDQ was represented by Law Offices of Yodice Associates of Potomac, MD, Rupprecht Law of Palm Beach Gardens, FL, and Parlatore Law Group of Washington, DC.

EASA issues guidelines for management of drone incidents at airports

The European Union Aviation Safety Agency (EASA) has published the 35-page “Drone Incident Management at Aerodromes” (PDF) manual. It provides guidance to help aviation operators and national authorities address unauthorized drone usage near airports. This is Part 1: The challenge of unauthorised drones in the surroundings of aerodromes. The other two parts are addressed to those parties involved in the management of these incidents.

MIT’s insect-sized drones are built to survive collisions

Generally, the smaller you make a drone, the more fragile it is. Insects, on the other hand, are very resilient for their size. The MIT lab recognised that if you are going to design an insect-sized drone, it needs to survive a collision. While older designs used rigid ceramic-based materials, the newer designs are built with soft actuators made with carbon nanotube-coated rubber cylinders that elongate when electricity is applied. These are used to simulate beating wings.

Erickson rebuilding Air Crane as potentially pilotless combat logistics helicopter

Erickson is considering upgrading the S-64 Aircrane helicopter to make it an optionally piloted combat cargo transport. Adding the Sikorsky Matrix retrofit autonomy kit to become the S-64F+, the helicopter would remove the risk to pilots during nighttime operation through mountainous terrain.

Newly released incident reports detail US Navy’s ‘UFO’ encounters

Videos of US Navy F/A-18 fighters encountering “unidentified aerial phenomena” have been circulating for some time, and the Pentagon has officially declassified and released the videos. Now the Navy has publically released incident reports that describe many of the unidentified aircraft as “Unmanned Aerial Systems.”

In June 2013, the encountered “aircraft was white in color and approximately the size and shape of a drone or missile.”
In November 2013, the aircraft was described as having a 5-foot wingspan. “…the aircraft was determined to be a UAS.”
From a March 2014 incident: “The unknown aircraft appeared to be small in size, approximately the size of a suitcase, and silver in color.”

How Are Drone Programs Utilizing Distance-Learning Setups?

How the wings of owls and hummingbirds inspire drones, wind turbines and other technology

“…biomimicry draws inspiration from natural inventions to design and improve upon our current technologies.” The hummingbird offers large wing muscles to continuously flap their wings, a long chest bone for the surface area needed for those muscles, and a figure-8 wing-beating pattern. The AeroVironment’s Nano Hummingbird prototype for DARPA (the U.S. Defense Advanced Research Projects Agency) draws on these qualities.

Meanwhile, the owl employs silent tactics, despite it’s huge wings. Owl wing feathers have leading-edge serrations that break up the turbulence that causes noise. Also, fringes at the end of the feathers further disburse turbulence and reduce noise. Similar turbulence-disrupting structures can reduce the noise produced by wind turbines and fans.

I measure whales with drones to find out if they’re fat enough to breed

Many whales and dolphins spend little time at the surface of the water, so they are hard to find and difficult to study. A Southern Cross University PhD candidate and scientist plans to use drones to find and measure the length and width of whales. Using photogrammetry techniques, video will be recorded of humpback and pygmy blue whales in Australian waters. With the measurements taken, the size and volume of a whale can be calculated. This provides an indication of its health.
