Cockroaches are near-indestructible little creatures. These hardy insects have existed since at least 320 million years ago, outliving dinosaurs. A cockroach can also carry loads of up to 900 times its body weight, shrink to a quarter of its height to fit into small crevices and live for a week without its head.
Inspired by the qualities of this humble bug, a group of researchers from China and the United States have created a prototype of a fast-moving and near-indestructible miniature robot, which could potentially replace sniffer dogs in detecting people trapped in a rubble after a major earthquake or similar disastrous event.
Researchers from China’s Tsinghua University and the University of California, Berkeley, published their study on so-called soft robots in the academic journal Science Robotics last week.
“Although the cockroach is an annoying pest, it has certain interesting features, including the ability to move fast in a narrow space and being hard to squash,” said Zhang Min, an assistant professor at Tsinghua University’s Graduate School in Shenzhen and one of the study’s authors, in an email interview. “These features inspired us to develop a fast-moving and robust soft robot.”

Their work on soft robots was conducted under the Tsinghua-Berkeley Shenzhen Institute partnership, an initiative to collaborate with global researchers on fields such as environmental science and new energy technology.

Scientists have long taken inspiration from insects, including cockroaches, for engineering robots. Researchers from UC Berkeley previously developed a palm-sized, roach-like robot – about 20 times the size of the bug – for rescue use in 2017.

By comparison, the new prototype achieved breakthroughs in terms of size and more importantly, the speed and robustness.

The latest robot, which is about the size of a postage stamp and weighs less than one-tenth of a gram, is composed of a flexible piezoelectric thin film and a polymer skeleton with two legs.

Despite its petite frame, this prototype showed the fastest speed among insect-scale robots in a similar weight range, as well as “ultra-robustness”, according to Lin Liwei, a professor of mechanical engineering at UC Berkeley who directed the research, in a separate email interview.

It can move as fast as a cockroach with speeds of up to 20 body lengths per second. It also continued to move after it was stepped on by an adult human weighting 60 kilograms, which is about 1 million times heavier than the robot, according to the study.

In 2017, researchers of the PolyPEDAL Lab at the University of California, Berkeley, designed a compressible robot, CRAM, that was about 20 times the size of a real cockroach. Photo: Handout

Those features sets up the robot for potential application in disaster relief, a field in which its size, agility and resilience would be invaluable to help detect survivors trapped beneath the rubble in catastrophes, such as major earthquakes.

Earthquakes have caused much devastation in China, a seismically active country with the world’s biggest population. For example, about 87,000 people died and more than 370,000 were injured when a magnitude-8 earthquake struck Wenchuan, a county in southwestern China’s Sichuan province, in 2008.

“The key innovation is the soft materials and structures used in the robot,” Lin said. “If the robot is too soft, it won’t be able to move fast. If the robot is too stiff, it can’t withstand the force of human weight.” The study detailed how the right combination of soft materials and structure enabled the robot to operate efficiently.

While the robot is currently attached to thin cables for power, the researchers are working to integrate a battery and control circuit to get rid of the existing wire in its design, helping expand its use in other applications.

“We want to make the robot carry small sensors, like a gas sensor, to provide it with more functions,” said Zhong Junwen, a researcher at UC Berkeley and one of the authors of the study, in a separate email interview. “With such a sensor, the robot can detect harmful gas leakage.”

Chinese authorities have declared a red alert as a powerful typhoon heads towards the eastern coast.

Typhoon Lekima is currently battering Taiwan with winds of more than 190km/h (120mph) and is due to make landfall in China’s Zhejiang province on Saturday.

Emergency teams have been deployed to the region to guide relief work, China’s emergency ministry said.

Thousands of people further up the coast in Shanghai have been warned to prepare to evacuate.

Lekima, which is the ninth typhoon so far this year, strengthened into a super typhoon late on Wednesday, but Taiwanese authorities have since downgraded it to a regular typhoon.

Flood warnings have been issued for eastern sections of China’s Yangtze River and the Yellow River until Wednesday. The provinces of Jiangsu and Shandong are also on alert.

Cruise liners have been told to delay their arrival in Shanghai and some train services have been suspended over the weekend.

Beijing has also cancelled some trains heading to and from the Yangtze delta region.

Lekima is one of two typhoons in the western Pacific at the moment. Further east, Typhoon Krosa is spreading heavy rain across the Northern Mariana Islands and Guam. It is moving north-west and could strike Japan some time next week, forecasters said.

Lekima was passing the north of Taiwan on Friday, causing flight cancellations and the closures of schools and offices.

Power was cut to more than 40,000 homes and the island’s high speed rail service was suspended north of the city of Taichung, local media reported.

The huge storm came a day after eastern Taiwan was rattled by a 6.0 magnitude earthquake. Experts said the risks of landslides triggered by the tremor were made more likely by the typhoon dumping up to 900mm (35 inches) of rain on Taiwan’s northern mountains.

Lekima also brought heavy rain and high winds to south-west Japan on Friday, cutting power to about 14,000 homes, broadcaster NHK reported.

China’s weather bureau said Lekima was expected to have weakened further by the time it made landfall. The country has a four-stage colour-coded warning system, with red representing the most severe weather.

Nestle starts selling Starbucks-branded coffee in China

SHANGHAI (Reuters) – Food giant Nestle (NESN.S) on Thursday started selling Starbucks-branded (SBUX.O) coffee in mainland China, seeking to tap growth in a market where it says coffee consumption per capita remains low compared to global standards.
Nestle last year paid $7.15 billion for exclusive rights to sell the U.S. chain’s coffees and teas globally, and began selling Starbucks-labelled products in Europe, Asia and Latin America in February.
The world’s largest food company will start selling 21 Starbucks-branded capsule and instant coffee products on Chinese e-commerce platforms like Alibaba’s (BABA.N) Tmall and JD.com (JD.O), as well as to offices and hotels in tier-1 cities, both companies said.
“We believe China is the most exciting market in general but especially for coffee because… per capita cup consumption is quite low as compared to Asia,” said Rashid Aleem Qureshi, Nestle’s chief executive officer for the Greater China region.
“Right now the overall soluble coffee in China is growing between 3-5% (a year) and we believe that by bringing this exciting new business opportunity we should be able to grow faster than that,” he said, referring to a category that includes capsule and instant coffee.
Nestle’s move comes as the Swiss company experienced a slower first-half growth in China, its second-largest market, where other categories like mainstream baby foods have struggled compared to pricier options.
China’s per capita coffee consumption is about 6 cups a year, compared to 400 in Japan and 300 in South Korea, Nestle said.
The partnership with Starbucks would help Nestle add a premium coffee option to the range of products it already sells in China, such as Nescafe instant coffee range and Nespresso capsule coffees, Qureshi said.
Starbucks China CEO Belinda Wong said the Nestle deal would open two new avenues to sell its products in China, where it has been investing heavily in its store network and delivery amid tougher competition from local startups.

Xinhua Headlines: China expands Shanghai FTZ for further opening-up, globalization

BEIJING, Aug. 6 (Xinhua) — China on Tuesday announced the expanding of its Shanghai free trade zone (FTZ) in its latest major strategic move for further opening-up.

The addition of the Lingang area is a major strategic decision made by the Communist Party of China Central Committee to further opening up, Vice Commerce Minister Wang Shouwen told a press conference Tuesday.

It also demonstrates China’s clear stand to adhere to all-round opening up in the new era and an important measure taken to actively lead the healthy development of economic globalization, Wang said.

The new Lingang section will match the standard of the most competitive free trade zones worldwide and implement opening-up policies and systems with strong global market competitiveness, according to an overall plan for the new Lingang area of the China (Shanghai) Pilot Free Trade Zone issued by the State Council, or the cabinet.

Lingang, with a start-up area of 119.5 square kilometers, will facilitate overseas investment and capital flows and realize the free flow of goods, according to the plan.

“The new area is not just a simple expansion of the existing free trade zone and a copy of existing policies. It is comprehensive, profound and fundamental institutional innovation and reform,” Chen Yin, executive vice mayor of Shanghai, told the press briefing.

The Shanghai FTZ had an area of 28.78 square kilometers when it was established in September 2013 and expanded to 120.72 square kilometers in December 2014.

Over the past years, the Shanghai FTZ has made remarkable progress in its bold exploration in sectors like investment, trade and finance and contributed precious experience to the all-around deepening of reforms and high-level opening-up, said Wang.

SPECIAL ZONE

The area will be built into a special economic function zone with global influence and competitiveness, to better serve the country’s overall opening-up strategy, the plan says.

“The status as a special economic function zone means that it is not adding more facilitation but moving toward real investment and trade liberalization,” said Shen Yuliang, a researcher with the Institute of World Economics under the Shanghai Academy of Social Sciences.

By 2025, the Lingang area will have a relatively mature institutional system of investment and trade liberalization and facilitation. By 2035, it will be built into a special economic function zone with strong global market influence and competitiveness, becoming an important platform for the country to integrate into economic globalization.

The area, administered like a special economic zone, will establish an institutional system with its focus on investment and trade liberalization and set up an open industrial system with global competitiveness, according to the plan.

It will strive to become a business cluster for international business, cross-border financial services, frontier technology research and development and cross-border services trade, and speed up the industrial upgrading of existing companies.

The Yangshan comprehensive bonded area will be set up there, and the area will also pilot free capital inflows and outflows and free capital conversion.

Income tax shall be levied at a reduced rate of 15 percent within five years from its establishment for qualified enterprises engaged in manufacturing and R&D in key fields including integrated circuits, artificial intelligence, biomedicine and civil aviation, says the plan.

Shanghai will also set up a fund of 100 billion yuan (14.2 billion U.S. dollars) in five years to support the development of the new area, said Chen.

OPENING-UP, INNOVATION LEADER

The plan says the new area will be granted greater administration power for self-development, self-reform and self-innovation, and regularly promote its experience to spearhead a new round of reform and opening-up of the Yangtze River Delta.

Apart from serving the Belt and Road Initiative and the Yangtze River Economic Belt, the new area is also designed to promote the coordinated development, reform and opening-up of the Yangtze River Delta, said Wang.

The Lingang area, home to Tesla’s gigafactory, has become a cluster of high-end industries after more than a decade of development, and it now emphasizes the development of key industries like integrated circuits, AI, biomedicine and civil aviation.

China’s economy faces complicated external situations and to improve industrial competitiveness and move up the value chain, the boost of scientific and technological innovation capacity is the only way, said Yin Chen, secretary general of the Shanghai Free Trade Zone Comprehensive Research Institute with Fudan University.

With more openness, the new area can boost Shanghai’s high-end resources allocation ability and better represent the country to take part in global cooperation and competition, said Yin.

BOON FOR BUSINESSES

The addition of the new area to the FTZ is a boon for both domestic and foreign businesses.

“The new tax policy support will help speed up the commercialization of autonomous driving,”said Xue Jiancong, vice president of TuSimple, an AI company registered in Lingang that received the country’s first open road testing license for trucks.

“We hope that the new policies will help promote the free flow of auto parts,”said Song Feng, president of Caterpillar Remanufacturing Services (Shanghai) Co., Ltd., citing current restrictions on imports of old machinery parts.

Yu Bo, a tax partner at accounting firm PwC, said China has been rolling out institutional reforms over the past years to allow domestic institutions in alignment with international standards.

China, among the top three investment destinations with the biggest development potential for business executives worldwide in an PwC survey, should continue to improve the business environment for foreign investment and conduct more institutional reforms to promote the higher-level opening-up, said Yu.

China, US sign UN protocol on mediation despite ongoing trade dispute

  • 46 countries agree protocol aimed at using mediation instead of legal action
  • Singapore set to capitalise on the naming of the convention, at Hong Kong’s expense

China and the United States have briefly put aside their escalating trade war and joined 44 other countries in signing a new global protocol on mediation aimed at settling cross-border trade and commercial disputes.
The Singapore Convention, under the United Nations framework, will allow mediation agreements to be recognised and enforced in the courts of all 46 signatories, which include South Korea and India. European Union nations are expected to sign in the next phase.
It was agreed against a backdrop of ongoing tensions between China and the US over tariffs and currency manipulation, and a trade dispute between South Korea and Japan

Speaking at the signing ceremony, Singapore Prime Minister Lee Hsien Loong said the protocol demonstrated that countries are capable of achieving consensus through effort and creativity, and are open to binding commitments.

He also observed that the established world order of multilateralism is “under pressure”.

“Existing multilateral institutions are not perfect, many are in need of urgent reform, suffer from a loss of confidence, or have practices and structures that are no longer fit for purpose,” Lee said, without elaborating which bodies he was referring to.

He added that the solution would not be to abandon these bodies, but to improve them through reform and bringing them up to date.
“We must make sure they reflect current economic and political realities, and ready them to deal with the new issues created by the progress of technology and globalisation.”

Stephen Mathias, the UN’s assistant secretary-general for legal affairs, said the agreement helped unify mediation rules and remove uncertainty in enforcing mediation agreements.

The protocol contains standardised terms to apply mediation agreements across jurisdictions, and is expected to bolster the use of mediation rather than legal action to resolve trade disputes.

This rare example of international cooperation can be likened to the New York Convention on arbitration, which was adopted by the UN 60 years ago and is now applied by 160 countries.

Singapore has also capitalised on the naming of the convention, positioning itself as the legal hub in the region, in competition with Hong Kong.

The UN’s Commission on International Trade Law, for instance, has signed a memorandum to establish an academy in international dispute resolution in Singapore.

Hong Kong or Singapore: who to trust on belt and road disputes?
Mediators in Hong Kong said the convention only served to promote their rival city, as Hong Kong professionals remain competitive in the market.
“Lots of cases with a ‘Chinese element’ would pick Hong Kong,” said lawyer Christopher To Wing. “For instance, a US or British firm runs into a dispute with a Chinese firm, they will choose Hong Kong, as the city is close to China.”
But he conceded that more support and funding from the Hong Kong government is needed to catch up with similar promotion efforts by the Singapore government.

More than 12,000 police officers assembled in Shenzhen in the southern Chinese province of Guangdong on Tuesday for a drill that included anti-riot measures similar to those seen on the streets of Hong Kong.
The drill was part of security preparations for the 70th anniversary of the People’s Republic of China on October 1, Shenzhen police said on the force’s Weibo newsfeed.

“A drill will be held to increase troop morale, practise and prepare for the security of celebrations, [and] maintain national political security and social stability,” police said.

In live videos of the police drills shown on the Yizhibo network, officers in body armour, helmets and shields confronted groups of people in black shirts and red or yellow construction safety helmets – similar to those worn by Hong Kong protesters – who were holding flags, banners, batons and wooden boards.

“The practice is complete with mature anti-mob tactics. The police forces can present an anti-mob formation, which is flexible, suitable for different situations, with accurate aim and effective control,” a narrator said during the live broadcast.

As the drill escalated and more “rioters” were deployed, police fired tear gas and smoke covered the training ground.

A few minutes later, the rioters fired home-made gas bombs then set bogies alight and drove them at the police lines. The officers changed formations and pressed the rioters, making arrests. Police handlers and their dogs were also on the scene.

Other drills included anti-smuggling and search-and-rescue exercises involving personnel from the People’s Liberation Army.

The drill was presented as preparation for the 70th anniversary celebrations but it came amid continued violence in the streets of Hong Kong and two incidents of the Chinese national flag being thrown into Victoria Harbour.

Hong Kong has been engulfed in two months of turmoil stemming from opposition to the now-suspended extradition bill.

“Is this hinting at Hong Kong?” a commenter on the Shenzhen police Weibo thread asked.

“We are doing drills today, and they can enter into real practice in Hong Kong in the future. We can send thousands of anti-mob squads over and strike hard at the radical traitors, those Hong Kong independence supporters,” another user said.

Since protests escalated in Hong Kong, Beijing has reiterated its “unflagging support” for embattled Hong Kong Chief Executive Carrie Lam Cheng Yuet-ngor and her administration to take lawful action to restore order, and warned that the city was entering “a most dangerous phase” with violence on the streets.
