On a congested sidewalk next to a busy mall in Shenzhen, a 20-something woman uses a smartphone app to order a milk tea on Meituan, a major food delivery company. In under ten minutes, the pearl-white drink arrives, not on the back of one of the city’s ubiquitous delivery bikes, but descending from the cloudy heavens, in a cardboard box on the back of a drone, into a small roadside kiosk. The only thing the scene is missing is a choir of angels.
Over the past two years, Meituan, one of China’s largest internet companies, has flown 19,000 meals to 8,000 customers across Shenzhen, a city with close to 20 million people. The pilot program is available to just seven neighborhoods, each with a three-kilometer stretch, and only from a select number of merchants. The drones deliver to designated streetside kiosks rather than hover outside people’s windows as envisioned by sci-fi writers. But the trials are proof of concept for Meituan’s ambitions, and the company is now ready to ramp up its aerial delivery ambitions.
Tencent-backed Meituan isn’t the only Chinese tech giant that hopes to fill urban skies with tiny fliers. Alibaba, which runs Meituan’s rival Ele.me, and e-commerce powerhouse JD.com, have also invested in similar drone delivery services in recent years.
On the back of the pilot program, Meituan has applied to operate a commercial drone delivery service across all of Shenzhen, Mao Yinian, head of the company’s drone delivery unit, said at a press event this month. The application, submitted in September, is currently under review by Shenzhen’s aviation authority and is expected to receive approval in 2022, though the actual timeline is subject to government decisions.
“We went from experimenting in the suburbs to a central area. That means our operational capability has reached a new level,” said Chen Tianjian, technical expert at Meituan’s drone business, at the same event.
At the moment, Meituan’s delivery drones still involve a good amount of manpower. Take the milk tea order, for example. Once the drink is ready, Meituan’s backend dispatch system assigns a human courier to fetch it from the merchant in the mall to the roof of the complex, where the company has set up drone takeoff pads.
Before takeoff, an inspector checks to see if the box holding the drink is secure. Meituan’s navigation system then calculates the quickest and safest route for the flyer to reach the pickup kiosk and off it goes, the milk tea into the sky.
The economic viability for using drones to deliver food of course is still unproven. Each of Meituan’s small aircraft, which are built with carbon fiber and weigh around 4 kilograms, can carry about 2.5 kilograms of food — roughly the weight of an average two-person meal, according to Chen. If someone orders just one cup of milk tea, the remaining space is wasted. Each kiosk can hold about 28 orders, so at peak hours, Meituan is betting on customers to gather their food promptly.
There’s also the matter of creating waste with the new delivery boxes. Meituan said it has set up recyclable bins next to the kiosks, but customers are also free to keep the containers. It won’t be surprised if some simply chuck them in the trash.
Lessons from the U.S.
From 2017 to 2018, China’s civil aviation authority started “following” the U.S. in light of research done by the Federal Aviation Administration on low-altitude aerial mobility, according to Chen. Not long after, the Chinese regulator began formulating guides and rules for this budding field. Meituan has similarly studied the paths of its American drone counterparts, but it realizes there isn’t a one-size-fits-all solution, as the two countries vary markedly in population density and consumer behavior.
Most Americans live in suburban sprawl, while in China and many other Asian countries, people are concentrated in urban clusters. As a result, drones in the U.S. are “focused more on endurance,” Chen said. Drones developed by Google and Amazon, for example, tend to be “fixed-winged with vertical landing and takeoff abilities,” while Meituan’s solution falls into the category of a small helicopter, which is more suited for complex urban environments.
Technologies emerging in the U.S. often offer useful clues to similar developments in China. The picture doesn’t look particularly rosy at Amazon Prime Air. The behemoth’s drone delivery business reportedly has been missing deadlines and laying off staff, though the firm said the unit continued to “make great strides.”
Prime Air, Chen argued, “doesn’t seem to have a clear strategy” and “has been vacillating between” neighborhood delivery, which is the focus of Alphabet’s Wing, and long-distance transport, which is UPS’s strong suit. He continued:
If you look at the competition between China and the U.S. in low-altitude aerial logistics, the important thing is to figure out one’s strategic position. Everyone can design a UVA. The question is what kind of UVA and for what customers.
When asked about the safety of drone delivery, Chen said Meituan’s solution “strictly follows” the rules laid out by the “civil aviation authority.” The Beijing-headquartered company picked Shenzhen as its testing field not only because it’s home to drone giant DJI and a mature UAV supply chain. The southern metropolis, known for its economic experiments, also has some of the most friendly drone policies in China, the expert said.
Each of Meituan’s drones is registered with Shenzhen’s Unmanned Aircraft Traffic Management Information Service System (UATMISS). During flights, they are required to pin UATMISS with their precise locations every five seconds. More important, Meituan’s navigation system works to ensure the flyers avoid crowds and built-up areas on the ground, even at the cost of making detours.
The drones being piloted are Meituan’s third iteration on the model. They boast a noise level of about 50 decibels heard from a 15-meter distance, which is equivalent to “daytime street level,” according to Chen. The next generation will be even quieter with noise reduced to “nighttime street level.” But the small aircraft can’t be too quiet, as regulators have advised that having an acceptable level of noise “is safer.”
Meituan doesn’t plan to replace its millions of couriers in China with unmanned flyers outright, though automation would take some load off its overworked delivery platform. Its dispatch algorithms have come under criticism from both the public and the government for allegedly putting business performance business above rider safety. The challenge to recruit workers has already prompted labor-intensive industries to seek out robotic help.
Meituan’s goal is to find a sweet spot for human-robot collaboration. Shenzhen’s road infrastructure is notoriously unfriendly to scooter drivers and cyclists, but aerial travel isn’t restricted by such ground obstructions. Drones can fly over large interchanges and put meals at spots convenient for couriers to fetch and carry to customers’ final destination.
Meituan is already envisaging more automation. For instance, rather than having its staff manually swap depleted drone batteries, it has done R&D on automated battery swap stations. It’s also exploring a conveyor belt-like system that can move items from restaurants to drone takeoff pads nearby. These solutions are still years from large-scale deployment, but the food delivery titan is clearly gliding into an automated future.
