The world of drone delivery services has been buzzing with excitement in recent years. While most people associate this technology with companies like Amazon, few realize that it is already being used for a much greater purpose in the developing world. In particular, Rwanda has made significant strides in utilizing autonomous drones to deliver essential medical products to remote areas with poor infrastructure.
Rwanda, with its modern and clean capital city of Kigali, faces a significant challenge when it comes to transportation outside the city. With only 2,600 kilometers of paved roads out of a total 14,000 kilometers, rural villages suffer from limited access to medical supplies. Zipline, a company dedicated to solving this problem, has developed a fleet of autonomous drones capable of carrying 1.6 kilograms of medical supplies, including blood and vaccines.
The Design Philosophy of Zipline’s Drones
Zipline’s drones are a marvel of engineering design, with several unique factors that influence their functionality and efficiency. One of the critical factors is the speed at which the drones need to take flight. Zipline aims to have the drone in the air within just 5 minutes from the moment an order is placed. To achieve this, they have moved the GPS circuitry from the plane to the battery, eliminating the delay usually associated with connecting to GPS satellites.
The modular design of the drone makes it easier to handle and assemble. It also allows for quick component swapping, improving the efficiency of pre-flight checks. Zipline has implemented a mobile app with computer vision algorithms to conduct these checks swiftly. Additionally, the launch process itself is streamlined, utilizing a pulley and electric motor system to accelerate the drone to its cruising speed of 100 kilometers per hour in just 0.3 seconds.
Landing and Safety Measures
Landing is often the most challenging stage of a flight, but Zipline has developed a reliable and innovative landing system. A small hook at the end of the tail boom catches a wire strung between two actuated arms, ensuring a safe and controlled landing. The drone communicates its location in 3D space with radio receivers, minimizing the risk of collision with the wire.
Zipline prioritizes safety in its autonomous drone network, incorporating redundancy of parts to prevent accidents. They have two of everything, including two motors, two actuators, and a parachute system in case of emergencies. This focus on safety has allowed Zipline to maintain an impeccable track record, with zero accidents causing injury since their service began in October 2016.
Efficiency and Range
In terms of efficiency, Zipline has opted for planes over quadcopters due to the former’s lower energy consumption and greater range. Zipline’s planes have a cruising speed of 100 kilometers per hour and a range of 160 kilometers, serving an 80-kilometer zone around their location. The lightweight carbon fiber composite construction of the fuselage, along with 3D-printed plastics, contributes to the overall weight of just 6.4 kilograms.
The Future of Drone Delivery
Zipline’s success in Rwanda serves not only as a humanitarian effort but also as a valuable testbed for integrating autonomous drones into a country’s air traffic control. This experience allows Zipline to refine their autonomous drone control system, optimizing the drone delivery network and expanding into territories with more complex airspaces.
The potential applications of this technology extend beyond developing countries. Drones can serve as a vital lifeline during disaster relief efforts when roads are impassable or in scenarios where centralized emergency supplies are needed quickly. Additionally, the use of drones minimizes human exposure to contagious diseases during quarantines, helping to prevent the spread of infection.
Conclusion
Zipline’s drone delivery system has revolutionized medical supply delivery in Rwanda and holds great potential for the future. With their focus on engineering design, safety, and efficiency, Zipline continues to refine and expand their network. By harnessing the power of autonomous drones, Zipline is transforming the way medical supplies reach remote areas, saving lives and improving healthcare access for those in need.
