Pandemic pushes Chinese tech giants to roll out more courier robots

Published

on

More than a thousand robots are set to join the delivery personnel ranks of Chinese behemoths Alibaba, Meituan and JD.com over the next year as the pandemic fuels demand for contactless services, Reuters reported.

The firms expect to operate over 2,000 robots between them by 2022, up about four-fold from now, their executives said, encouraged also by falling costs of making robots.

Millions of couriers still deliver packages for as less as 3 yuan ($0.47) in China, but companies have been exploring the use of drones or box-like robots on wheels from as early as 2013 amid a labour crunch that has worsened due to the pandemic.

According to the report Beijing has also ordered firms to ensure rest periods for couriers as they scramble to meet rising demand and deadlines.

“The COVID-19 pandemic has been a big boost” for robot rollout plans, said Xia Huaxia, chief scientist at Meituan.

The food-delivery giant launched its robot service in February 2020 when infections were high in Beijing, earlier than a planned end-year launch, read the report.

JD.com too brought forward its plans to launch its robot service, said Kong Qi, chief scientist of the e-commerce giant’s autonomous driving unit. It had targeted a June 2020 launch in Beijing, but started using the service in Wuhan in February as the central Chinese city was locked down.

“We want people and vehicles to work better together and not for vehicles to replace people. It is just in the most boring section of the delivery guy’s work that we will try to replace,” he said.

LIMITS VS BENEFITS

Still, human delivery personnel outnumber robots, which have limitations such as inability to climb stairs. Also, robots are only allowed on certain routes like in housing estates and school campuses because of speed limits and road conditions.

Robots also tend to be used to deliver less time-sensitive products like packages, rather than food.

“The efficiency is low for office areas where people are ordering a lot of food and parcels but the vehicle’s capacity is limited,” said 25-year-old Zhang Ji as she picked up a package delivered by an autonomous vehicle near her office in Beijing.

But proponents espouse long-term benefits of robots such as lower last-mile delivery costs. Researchers at the University of Michigan said fully and partially automated vehicles could cut delivery costs by 10−40% in cities.

Alibaba’s last-mile logistics vehicle has delivered over a million orders as of September to more than 200,000 consumers, the company said. It operates over 200 robots and plans to have 1,000 by March and 10,000 over the next three years, Reuters reported.

COSTS ARE DOWN

Costs of making robots are down, said Wang Gang, vice president at Alibaba who is in charge of autonomous driving, mainly due to lower prices of lidar sensors that help measure distances and render images around vehicles.

Alibaba and JD.com said the cost of making their robots was below 250,000 yuan ($38,662) apiece and falling.

JD.com, which operates about 200 robots, plans to expand to some 1,000 units by the end of 2021.

Meituan sees the cost of making its robots at around 400,000 yuan this year, versus 600,000 yuan in 2020, Xia said.

Meituan’s robot will cost less than 200,000 yuan in 2025, which is when the industry will see mass-application of over 10,000 units of such robots, Xia said.

Meituan currently has around 100 delivery robots, read the report.

Delivery firms in other countries have also been testing robots. Russian’s Yandex and online food-ordering company GrubHub plan to start using driverless robots to deliver food on U.S. college campuses.

“I hope robots can be used widely soon because it will make our life more convenient … it will also reduce face-to-face contact during the pandemic so we can be safer,” said 28-year-old Pan Hongju, a programmer in Beijing.

Swirling, vortex-like patterns observed on the sun’s surface

The researchers said the observations may provide insight into underlying physical processes that impact ⁠the dynamics of the sun and other stars, including eruptions from the solar surface that can interfere with the operation of satellites, GPS navigation, power grids and global communications on ​Earth.

Astronomers have obtained the highest-resolution images to date of our sun’s visible surface, observing swirling, vortex-like patterns in superheated solar gases reminiscent of the shapes depicted in ​the nocturnal sky in Vincent van Gogh’s 1889 painting “The Starry Night.”

The researchers made the observations of a portion of the sun’s photosphere, a relatively thin ‌layer — about 60 miles (100 km) in depth compared to the overall solar diameter of roughly 865,000 miles (1.4 million km) — using the U.S. National Science Foundation’s Hawaii-based Daniel K. Inouye Solar Telescope, Reuters reported.

The still images and time-lapse video reveal continuously growing whirls of hot plasma, gas heated to temperatures so high that subatomic particles called electrons break free from atoms and form a broth of charged particles. The observed whirls are large on ​a human scale but small on the scale of a stellar surface, with diameters ranging from about 12 miles (19 km) — the minimum scale detectable by the world’s ​most powerful solar telescope — up to roughly 100 miles (170 km).

The researchers said the observations may provide insight into underlying physical processes that impact ⁠the dynamics of the sun and other stars, including eruptions from the solar surface that can interfere with the operation of satellites, GPS navigation, power grids and global communications on ​Earth.

The curly, circular patterns do not represent random shapes, but rather are the first detection of a phenomenon called Kelvin-Helmholtz instability, or KHI, on the surface of a star. KHI, first described ​in the 19th century, refers to a dynamic process that happens when two parallel streams of fluids or gases interact while moving at different velocities.

“The interface can become unstable and develop wave-like vortices that grow in size until they break apart, not unlike waves out on a lake or out on the ocean in windy conditions,” said astronomer Friedrich Wöger, a senior scientist at the National Science Foundation’s National Solar Observatory ​in Colorado, the Inouye telescope’s instrument program scientist, and co-lead author of the study published on Wednesday in the journal Nature.

Swirling clouds caused by KHI are a well-known, albeit rare, meteorological ​occurrence on Earth, and also have been observed in the atmospheres of the giant gas planets Jupiter and Saturn, Wöger said.

“The difference from the waves and clouds we know here on Earth is that the two ‌interacting fluids ⁠are hot plasma — about 6,000 degrees Kelvin and 10,000 degrees Fahrenheit (5,540 degrees Celsius) — moving within a magnetic field that helps create the conditions for the instability to develop,” Wöger said.

By twisting the solar magnetic field, KHI creates energy that can suddenly unleash an explosion.

‘A TRUE GAME-CHANGER’

Wöger called the discovery of solar KHI “a true game-changer,” saying it opens up a new framework for understanding how the sun energizes its atmosphere.

“The sun and sun-like stars are extremely dynamic systems, characterized by a whole spectrum of rapid, explosive events within their magnetic elements. How these explosions ​are triggered is one of the main frontiers ​in modern solar physics,” National Solar Observatory ⁠astronomer and study co-lead author David Kuridze said.

The KHI manifestation might help explain why the sun’s outer atmosphere becomes as hot as it does and why magnetic energy accumulates and moves around on the solar surface.

The constant twisting motions generated by KHI can gradually build the ​energy required to trigger coronal mass ejections and solar flares, Kuridze said. Coronal mass ejections are huge bubbles of gas threaded with ​magnetic field lines that ⁠are expelled from the sun’s surface. Solar flares are gigantic explosions on the sun that propel light, energy and high-speed particles into space.

Aside from the science, the researchers admired the beauty of the new close-up views of the sun.

“Maybe ‘magnificent’ comes closest to describing the aesthetics in the images for us,” Wöger said.

“Interestingly, artists have long captured this fluid dynamic intuition in their work. A famous ⁠example is Van ​Gogh’s ‘The Starry Night,’ where the sky’s vortex structures closely resemble turbulent KHI structures,” Kuridze said. “A similar parallel appears ​in Hokusai’s famous woodblock print, ‘The Great Wave off Kanagawa,’ where the curling crests of the wave echo the iconic shape of KHI billows. It shows how the fundamental geometry of nature deeply resonates with human art.”

Afghanistan currently transits internet traffic to Central Asia, says MCIT

Published

on

Afghanistan is currently serving as a transit route for internet traffic between South Asia and Central Asia, the Ministry of Communications and Information Technology (MCIT) said, highlighting the country’s growing role in regional digital connectivity.

The ministry said fiber-optic traffic from several South Asian countries is routed through Afghanistan to Central Asian nations via the country’s fiber-optic network.

According to the ministry, nearly $3 billion has been invested in Afghanistan’s fiber-optic and telecommunications sector so far, with expansion efforts continuing.

Officials said Afghanistan offers significant investment opportunities in telecommunications and fiber-optic infrastructure. They added that, alongside expanding domestic communications services, the ministry is working to enhance the country’s capacity to provide transit services for regional countries.

The ministry said Afghanistan is already facilitating the transit of internet traffic from parts of South Asia to Central Asia and stressed that the country’s strategic geographic location positions it as an important digital corridor between the two regions.

“We are currently transiting internet traffic through Afghanistan to South Asian and Central Asian countries,” said Enayatullah Alokozai, spokesperson for the Ministry of Communications and Information Technology. “Afghanistan is a suitable geographical corridor for data transmission.”

Economic analysts say Afghanistan has the potential to become a key hub for regional connectivity. They noted that, in addition to serving as a corridor for energy transmission from Central Asia, the country could also facilitate the large-scale transit of fiber-optic connectivity, internet traffic, and commercial goods.

Representatives of the private sector also said Afghanistan has strong potential to attract further investment in telecommunications and fiber-optic infrastructure. They noted that numerous domestic and international companies are active in the sector, creating direct employment opportunities for thousands of Afghans.

New AI tool helps Afghans identify visa pathways

Published

on

A veteran-led organisation has launched a new artificial intelligence-powered platform designed to help Afghans navigate complex visa and relocation options as thousands remain stranded or at risk nearly five years after the withdrawal of U.S. forces from Afghanistan.

The Visa Pathways and Relocation Information Center (V-PRIC), developed by AfghanEvac, uses artificial intelligence to guide users through possible immigration and protection pathways based on their individual circumstances.

According to AfghanEvac founder and U.S. Navy veteran Shawn VanDiver, the platform attracted more than 30,000 visits during its first week online.

Users begin by answering questions about their current location, whether they worked with the United States, whether they face security risks, and by providing a brief description of their situation. The system then compares that information with a database covering 124 U.S. visa and immigration categories, including 16 relevant to Afghan applicants, as well as relocation options offered by other countries.

VanDiver said the platform is intended to simplify what is often a confusing and constantly changing immigration process. Before using the service, applicants must acknowledge that it does not provide legal advice.

The launch comes as many Afghans who supported the U.S. during its two-decade military presence continue to face uncertainty. AfghanEvac says policy changes have significantly reduced available relocation opportunities, leaving many applicants unable to progress with immigration cases.

According to the organisation, around 1,100 Afghan allies and their family members remain at the Camp As Sayliyah processing facility in Doha, Qatar, despite many having previously received approval to enter the United States. AfghanEvac says travel restrictions have prevented them from completing the process.

VanDiver said the new tool helps users identify obstacles affecting their applications, including whether delays are caused by legal requirements or government policy, while also highlighting possible next steps.

The platform has been trained using legal decisions, executive orders, policy documents and information gathered through AfghanEvac surveys and guidance materials. The organisation says it will continue updating the system as immigration policies evolve.

VanDiver said the tool could also help applicants avoid actions that may complicate future immigration cases, such as pursuing visa interviews when programmes are temporarily suspended.

AfghanEvac recently surveyed more than 1,100 Afghans between January and July this year. Of the 427 respondents still inside Afghanistan, nearly half reported facing direct security threats. Another 427 respondents were in Pakistan awaiting relocation, with many expressing concerns about possible deportation and limited access to healthcare.

The organisation emphasised that the AI platform is intended to complement, rather than replace, professional legal assistance. It encourages applicants to seek legal advice while using the service to better understand the immigration options available to them.
