Drone Deliveries to Hospitals in Rwanda

Posted on June 25, 2017  Comments (5)

Partnering with the Government of Rwanda, Zipline serves 21 hospitals nation-wide. They provide instant deliveries of lifesaving blood products for 8 million Rwandans.

Their drones are tiny airplanes (instead of the more common tiny helicopter model). Supplies are delivered using parachute drops from the drone. Landings are similar to landings on aircraft carriers (they grab a line to help slow down the drone) and, in a difference from aircraft carrier landings, the drone line drops them onto a large air cushion.

Zipline Muhanga Distribution Center launched in October 2016 making Rwanda the first country to integrate drones into their airspace and to begin daily operations of autonomous delivery.

As of May 2017, Zipline had completed over 350 delivery flights to real hospitals and their pace is accelerating. Zipline can cut delivery time from 4 hours to 15 minutes (which is extremely important in time critical health care emergencies).

I wrote in 2014 about the huge potential for drone delivery of medical supplies. It is wonderful to see Zipline improving people’s lives with their effort.

14 Year Old Signs $700,000 MOU for a Drone to Detect and Defuse Land Mines

Posted on January 14, 2017  Comments (4)

Harshwardhan Zala, from Gujarat, India has signed an agreement worth Rs. 5 crore (US$733,940) to explore the possibility of commercial production of a drone created by him which can help in detecting and defusing landmines.

Harshwardhan started work on the prototype of the landmine-detecting drone last year after reading in newspapers about high army casualties due to landmines. Aerobotics7 is the company founded by the 14 years old.

Explaining more about the drone, the zealous 14-year-old said, “The drone is designed to send out waves that cover eight sq. mt area while flying two feet above the surface; the waves detect land mines and communicate their location with a base station. The drone also carries a bomb weighing 50 gram that can be used to destroy the landmine.” Harshwardhan Zala’s proud father Pradhyumansinh is an accountant with a plastic company in Naroda, and his mother Nishaba is a homemaker.

The video has Harshwardhan speaking a bit of English but mainly some other language that I don’t understand. If I understand right, his drone is 98% accurate at identifying mines (where the current solutions are 92% accurate – and much more dangerous for those having to walk around testing). His solution is 17 times faster and 22 times cheaper than the current solutions. Once the mine is detected by the drone through an infrared sensor, a 50 gram detonator will complete the task of defusing it (blowing it up).

US Fish and Wildlife Service Plans to Use Drones to Drop Vaccine Treats to Save Ferrets

Posted on July 16, 2016  Comments (0)

Despite significant recovery successes, the black-footed ferret remains one of the most endangered animals in the world.

The U.S. Fish and Wildlife Service has developed a plan to use (UAS) to deliver prairie dog sylvatic plague vaccination.

The primary purpose in this proposal is to develop the equipment, protocols and experience in use of UAS (drones) to deliver oral sylvatic plague vaccine (SPV). It is anticipated that this approach, when fully developed, will offer the most efficient, effective, cost-conscious and environmentally friendly method to apply SPV annually over large areas of prairie dog colonies in support of black-footed ferret recovery.

Plague is a primary obstacle to black-footed ferret recovery. After more than 20 years of intensive reintroduction efforts across 27 reintroduction sites ranging from Mexico to Canada, approximately 300 ferrets were known to exist in the wild at the end of 2015. Ferrets are constantly threatened by plague outbreaks that affect both ferrets, and their primary prey and habitat provider, prairie dogs.

To date, SPV has been applied by hand with people walking pre-defined transects and uniformly dropping single SPV baits every 9-10 meters to achieve a deposition rate of 50 SPV doses per acre. Depending on vegetation and terrain, a single person walking can treat 3-6 acres per hour. All terrain vehicles (ATVs) have been considered but have various problems.

The bait treats are M&Ms smeared in vaccine-laden peanut butter.

Preliminary discussions with people experienced with UAS suggest an aerial vehicle travelling at a modest 9 meters per second could drop a single SPV bait once per second that would result in treating one acre every 50 seconds. If the equipment and expertise can be developed as proposed here, a single UAS operator could treat more than 60 acres per hour.

If the equipment can be developed to deposit 3 SPV doses simultaneously every second, as they envision is possible, some 200 acres per hour could be treated by a single operator. The idea is that the drone would fire the treats in 3 different directions to increase the spread of treats.

The areas to be treated are located in South Phillips County, Montana.
