The global push to put autonomous taxis on public roads is accelerating as ride-hailing companies and technology firms advance from pilot programs toward limited commercial rollouts in cities across China, the United States, Europe and the Middle East.

WeRide and Uber launched Level 4 fully driverless robotaxi operations in Abu Dhabi in November and began offering robotaxi passenger rides on Uber's platform in Dubai the following month. Amazon's Zoox started offering free rides to select early users in parts of San Francisco in November after launching its autonomous ride-hailing service on the Las Vegas Strip in September. Alphabet's Waymo now operates services in Phoenix, San Francisco, and Los Angeles -- the latter two having launched in June and November 2024 respectively.

Baidu's Apollo Go has been operating without safety drivers in Chongqing and Wuhan since securing permits in August 2022 and has since expanded to Shenzhen and Beijing. Pony.ai launched paid robotaxi services in Guangzhou in February and Shanghai in August. Tesla began a limited paid robotaxi rollout in Austin, Texas in June using Model Y SUVs, though the vehicles still require a safety monitor onboard. The expansion will continue in 2026: Waymo plans to launch an autonomous ride-hailing service in London, and Momenta is preparing a luxury robotaxi service in Abu Dhabi through a partnership with Mercedes-Benz and UAE taxi operator Lumo.

An anonymous reader shares a report: China on Friday launched three venture capital funds to invest in "hard technology" areas, state broadcaster CCTV reported. The capital contribution plans for the funds have been finalised, each with more than 50 billion yuan ($7.14 billion), according to the report. The funds will primarily invest in early-stage startups and the targets should be valued at less than 500 million yuan, an official said on Friday, adding that no single investment would amount to more than 50 million yuan.

An anonymous reader shares a report: Chinese social media users criticized two key government policies, rare signs of public dissent in the country where the internet is heavily censored. The death of the former head of China's one-child policy agency -- which for decades forced women to carry out abortions and sterilizations -- sparked criticism of the demographic effort, with one netizen lamenting the "children who were lost."

Others, meanwhile, criticized Beijing's leadership over its ongoing row with Tokyo, sparked by Japanese Prime Minister Sanae Takaichi saying her country could intervene to defend Taiwan in a potential Chinese attack on the self-ruled island, which Beijing claims as its own.

An anonymous reader quotes a report from the Wall Street Journal: Concerned that artificial intelligence could threaten Communist Party rule, Beijing is taking extraordinary steps to keep it under control. Although China's government sees AI as crucial to the country's economic and military future, regulations and recent purges of online content show it also fears AI could destabilize society. Chatbots pose a particular problem: Their ability to think for themselves could generate responses that spur people to question party rule.

In November, Beijing formalized rules it has been working on with AI companies to ensure their chatbots are trained on data filtered for politically sensitive content, and that they can pass an ideological test before going public. All AI-generated texts, videos and images must be explicitly labeled and traceable, making it easier to track and punish anyone spreading undesirable content. Authorities recently said they removed 960,000 pieces of what they regarded as illegal or harmful AI-generated content during three months of an enforcement campaign. Authorities have officially classified AI as a major potential threat, adding it alongside earthquakes and epidemics to its National Emergency Response Plan.

Chinese authorities don't want to regulate too much, people familiar with the government's thinking said. Doing so could extinguish innovation and condemn China to second-tier status in the global AI race behind the U.S., which is taking a more hands-off approach toward policing AI. But Beijing also can't afford to let AI run amok. Chinese leader Xi Jinping said earlier this year that AI brought "unprecedented risks," according to state media. A lieutenant called AI without safety like driving on a highway without brakes. There are signs that China is, for now, finding a way to thread the needle.

Chinese models are scoring well in international rankings, both overall and in specific areas such as computer coding, even as they censor responses about the Tiananmen Square massacre, human-rights concerns and other sensitive topics. Major American AI models are for the most part unavailable in China. It could become harder for DeepSeek and other Chinese models to keep up with U.S. models as AI systems become more sophisticated. Researchers outside of China who have reviewed both Chinese and American models also say that China's regulatory approach has some benefits: Its chatbots are often safer by some metrics, with less violence and pornography, and are less likely to steer people toward self-harm. "The Communist Party's top priority has always been regulating political content, but there are people in the system who deeply care about the other social impacts of AI, especially on children," said Matt Sheehan, who studies Chinese AI at the Carnegie Endowment for International Peace, a think tank. "That may lead models to produce less dangerous content on certain dimensions."

Russia plans to put a nuclear power plant on the moon in the next decade to supply its lunar space programme and a joint Russian-Chinese research station, as major powers rush to explore the earth's only natural satellite. Reuters: Ever since Soviet cosmonaut Yuri Gagarin became the first human to go into space in 1961, Russia has prided itself as a leading power in space exploration, but in recent decades it has fallen behind the United States and, increasingly, China. Russia's ambitions suffered a massive blow in August 2023 when its unmanned Luna-25 mission smashed into the surface of the moon while attempting to land, and Elon Musk has revolutionised the launch of space vehicles - once a Russian speciality.

Russia's state space corporation, Roscosmos, said in a statement that it planned to build a lunar power plant by 2036 and signed a contract with the Lavochkin Association aerospace company to do it. Roscosmos did not say explicitly that the plant would be nuclear but it said the participants included Russian state nuclear corporation Rosatom and the Kurchatov Institute, Russia's leading nuclear research institute. Roscosmos said the purpose of the plant was to power Russia's lunar programme, including rovers, an observatory and the infrastructure of the joint Russian-Chinese International Lunar Research Station.

Goldman Sachs, in a note this week, via India Dispatch: There are various reasons that explains this: (i) A large part of the global education spend goes towards formal education (schools, colleges and universities), which are typically either run by governments or are not-for-profit institutions;

(ii) It is difficult to replicate education quality at scale in our view, since most teachers would have a different pedagogy, and thus standardization is harder to achieve vs that in other internet categories;

(iii) Education is fragmented - it includes various fields (schools, undergrad courses, medicine, engg, management, etc.), each with their own curriculum, and the same being vastly different across countries globally; this makes scalability difficult beyond a few certain specializations and regions.

Additionally, we believe the ability for online education to capture a sizable value share of supplemental education is limited since the perceived value of offline, including that from community, in-person engagement and doubt solving, rigour, etc., is typically higher.

However, we note that before China's double reduction policy in 2021, TAL and EDU had market caps of up to US$50 bn; these companies were mostly domestic focused and on the K-12 tutoring segment, which has large volumes. Similarly in India, Byju's reached a peak valuation of US$20 bn+ (link; again, focused on K-12), before issues around governance etc. impacted the business.

An anonymous reader shares a report: The United States will take action against China's semiconductor industry, setting new tariffs on chips from China from June 23, 2027, that have 0% duties currently, the US Trade Representative said.

The announcement comes following a year-long investigation into China's chip imports into the United States, launched by the Biden administration and led by the U.S. Trade Representative. "China's targeting of the semiconductor industry for dominance is unreasonable and burdens or restricts U.S. commerce and thus is actionable," the agency said in its release.

China has unveiled new rules to rein in aggressive pricing tactics by online platforms, prohibiting e-commerce operators from forcing merchants to offer discounts or setting different prices based on user demographics without consent. The 29-article regulation -- jointly issued over the weekend by the National Development and Reform Commission, State Administration for Market Regulation (SAMR), and Cyberspace Administration of China -- lays out detailed compliance requirements that target several long-standing pain points as competition among internet giants has often eroded the rights of both consumers and merchants.

To restore merchant autonomy on pricing, the rules ban platform operators from leveraging their dominant scale to impose "lowest price" agreements. Platforms are prohibited from using traffic throttling, search ranking demotions, or algorithm penalties to pressure merchants into predatory price-cutting or exclusive pricing arrangements.

Uber and Lyft plan to trial robotaxis in London starting in 2026 using autonomous vehicles from Baidu, as the UK fast-tracks approvals for self-driving cars on public roads. CNBC reports: Lyft's testing of Baidu's initial fleet of dozens of vehicles will begin in 2026, pending regulatory approval, "with plans to scale to hundreds from there," Lyft CEO David Risher said in a post on social media platform X on Monday. Meanwhile, Uber said that its first pilot is expected to start in the first half of 2026. "We're excited to accelerate Britain's leadership in the future of mobility, bringing another safe and reliable travel option to Londoners next year," the company added.

The moves add to Baidu's growing global footprint, which it says includes 22 cities and more than 250,000 weekly trips, as it races against other Chinese players like WeRide and Western giants like Alphabet's Waymo. The UK, in particular, has seen a wave of interest from driverless taxi companies, following the government's announcement in June that it would accelerate its plans to allow autonomous vehicle tech on public roads. The government now aims to begin permitting robotaxis to operate in small-scale pilots starting in spring 2026, with Baidu likely aiming to be among the first. The city of London has also established a "Vision Zero" goal to eliminate all serious injuries and deaths in its transportation systems by 2041, with autonomous driving technology expected to play a large role.

The FCC has banned approval of new foreign-made drones and components, citing "an unacceptable risk" to national security. The move will most heavily impact DJI but it "does not affect drones or drone components that are currently sold in the United States." Reuters reports: The tech was placed on the commission's "Covered List," barring DJI and other foreign drone manufacturers from receiving the FCC's approval to sell new drone models for import or sale in the U.S. In Monday's announcement, the agency said that the move "will reduce the risk of direct [drone] attacks and disruptions, unauthorized surveillance, sensitive data exfiltration and other [drone] threats to the homeland."

FCC Chair Brendan Carr said in a statement that while drones offer the potential to boost public safety and the U.S.' posture on global innovation, "criminals, terrorists and hostile foreign actors have intensified their weaponization of these technologies, creating new and serious threats to our homeland."

The ruling comes as China hawks in Congress amplify warnings about the security risks of drones made by DJI, which accounts for more than 90% of the global market share. But efforts to crack down on Capitol Hill have been met with some pushback due to the potential impacts of curbing the drone usage on U.S. businesses and law enforcement. A wide variety of sectors, including construction, energy, agriculture and mining companies, as well as local police and fire departments across the country, deploy DJI-made drones.

Abstract of a paper featured on NBER: How has aggregate income and welfare in the United States been affected by globalization and rapid productivity growth in emerging economies? We use the class of constant elasticity trade models to provide quantitative evidence on these questions. We find that reductions in worldwide trade frictions over the period from 1960-2020 reduced the share of the United States in global GDP but raised its aggregate welfare. Similarly, productivity growth in Japan and China led to a decline in the relative income of the United States, but brought aggregate welfare gains from the resulting expansion in global production possibilities. Trade integration and foreign productivity growth have relatively modest effects on domestic income and welfare compared to domestic productivity growth.

Tuesday the White House faces a deadline to decide "whether Chinese drone maker DJI Technologies poses a national security threat," reports Bloomberg. But their article notes it's "a decision with the potential to ground thousands of machines deployed by police and fire departments across the US."

One person making the case against the drones is Mike Nathe, a North Dakota Republican state representative described by the Post as "at the forefront of a nationwide campaign sounding alarms about the Made-in-China aircraft." Nathe tells them that "People do not realize the security issue with these drones, the amount of information that's being funneled back to China on a daily basis." The president already signed anexecutive orderin June targeting "foreign control or exploitation" of America's drone supply chain. That came after Congress mandated a review to determine whether DJI deserves inclusion in a federal register of companies believed to endanger national security. If DJI doesn't get a clean bill of health for Christmas, it could join Huawei Technologies Co. Ltd. and ZTE Corp.on that Federal Communications Commission list. The designation would give the Trump administration authority to prevent new domestic sales or even impose a flight ban, affecting public agencies from New York to North Dakota to Nevada...

The fleet used by public safety agencies nationwide exceeds about 25,000 aircraft, said Chris Fink, founder of Unmanned Vehicle Technologies LLC, a Fayetteville, Arkansas-based firm that advises law-enforcement clients. The overwhelming majority of those drones — called uncrewed aerial vehicles, or UAVs, in industry parlance — comes from China, said Jon Beal, president of theLaw Enforcement Drone Association, a training and advocacy group that counts DJI and some US competitors as corporate sponsors...

Currently, at least half a dozen states havetargeted DJIand other Chinese-manufactured drones, including restrictions in Arkansas, Mississippi and Tennessee. A Nevada law prohibiting public agencies from using Chinese drones took effect in January... Legislators also took up the cause in Connecticut, which passed a law this year preventing public offices from using Chinese drones. Supporters said they're worried about these eyes in the skies being used for spying. "We're kind of sitting ducks," said Bob Duff, the Democratic majority leader in the state senate who promoted the legislation. "They are designed to infiltrate systems even when the users don't think that they will."
One North Dakota sheriff's department complains U.S.-made drones are "at least double and triple the price out of the gate," according to the article, which adds that public safety officials "say it's difficult to find domestic alternatives that match DJI in price and performance."

And DJI "wants an extension on the security review," according to the article, "saying Tuesday is too soon to make a conclusion."

In July Google promised to scale the CO2 batteries of "Energy Dome" as a long-duration energy storage solution. Now IEEE Spectrum visits its first plant in Sardinia, where 2,000 tonnes of carbon dioxide power a turbine generating 20 MW over 10 hours — storing "large amounts of excess renewable energy until it's needed..."

"Google likes the concept so much that it plans to rapidly deploy the facilities in all of its key data-center locations in Europe, the United States, and the Asia-Pacific region." Developed by the Milan-based company Energy Dome, the bubble and its surrounding machinery demonstrate a first-of-its-kind "CO2 Battery," as the company calls it... And in 2026, replicas of this plant will start popping up across the globe. We mean that literally. It takes just half a day to inflate the bubble. The rest of the facility takes less than two years to build and can be done just about anywhere there's 5 hectares of flat land.

The first to build one outside of Sardinia will be one of India's largest power companies, NTPC Limited. The company expects to complete its CO2 Battery sometime in 2026 at the Kudgi power plant in Karnataka, in India. In Wisconsin, meanwhile, the public utility Alliant Energy received the all clear from authorities to begin construction of one in 2026 to supply power to 18,000 homes... The idea is to provide electricity-guzzling data centers with round-the-clock clean energy, even when the sun isn't shining or the wind isn't blowing. The partnership with Energy Dome, announced in July, marked Google's first investment in long-duration energy storage...

CO2 Batteries check a lot of boxes that other approaches don't. They don't need special topography like pumped-hydro reservoirs do. They don't need critical minerals like electrochemical and other batteries do. They use components for which supply chains already exist. Their expected lifetime stretches nearly three times as long as lithium-ion batteries. And adding size and storage capacity to them significantly decreases cost per kilowatt-hour. Energy Dome expects its LDES solution to be 30 percent cheaper than lithium-ion.

China has taken note. China Huadian Corp. and Dongfang Electric Corp. are reportedly building a CO2-based energy-storage facility in the Xinjiang region of northwest China.
Google's senior lead for energy storage says they like how Energy Dome's solution can work in any region. "They can really plug and play this."

And they expect Google to help the technology "reach a massive commercial stage."

An anonymous reader shared this report from CNBC: The Trump administration on Monday unveiled a new initiative dubbed the "U.S. Tech Force," comprising about 1,000 engineers and other specialists who will work on artificial intelligence infrastructure and other technology projects throughout the federal government.

Participants will commit to a two-year employment program working with teams that report directly to agency leaders in "collaboration with leading technology companies," according to an official government website. ["...and work closely with senior managers from companies partnering with the Tech Force."] Those "private sector partners" include Amazon Web Services, Apple, Google Public Sector, Dell Technologies, Microsoft, Nvidia, OpenAI, Oracle, Palantir, Salesforce and numerous others [including AMD, IBM, Coinbase, Robinhood, Uber, xAI, and Zoom], the website says.

The Tech Force shows the Trump administration increasing its focus on developing America's AI infrastructure as it competes with China for dominance in the rapidly growing industry... The engineering corps will be working on "high-impact technology initiatives including AI implementation, application development, data modernization, and digital service delivery across federal agencies," the site says.
"Answer the call," says the new web site at TechForce.gov.

"Upon completing the program, engineers can seek employment with the partnering private-sector companies for potential full-time roles — demonstrating the value of combining civil service with technical expertise." [And those private sector companies can also nominate employees to participate.] "Annual salaries are expected to be in the approximate range of $150,000 to $200,000."

An anonymous reader shared this report from the Washington Post. (Alternate URL here): The American patrol satellite had the targets in its sights: two recently launched Chinese spacecraft flying through one of the most sensitive neighborhoods in space. Like any good tactical fighter, the American spacecraft, known as USA 270, approached from behind, so that the sun would be at its back, illuminating the quarry.

But then one of the Chinese satellites countered by slowing down. As USA 270 zipped by, the Chinese satellite dropped in behind its American pursuer, like Maverick's signature "hit-the-brakes" move in the movie "Top Gun." The positions reversed, U.S. officials controlling their spacecraft from Earth were forced to plot their next move. The encounter some 22,000 miles above Earth in 2022 was never acknowledged publicly by the Pentagon or Beijing. Happening out of sight and little noticed except by space and defense specialists, this kind of orbital skirmishing has become so common that defense officials now refer to it as "dogfighting..."

Much of the "dogfighting" activity in space is simply for spying, defense analysts say, with specifics largely classified — snapping photos of each other's satellites to learn what kind of systems are on board and their capabilities. They monitor the signals and data emitted by satellites, listening to communications between space and the ground. Many can even jam those signals or interfere with orbiting craft that provide missile warnings, spy or relay critical information to troops... Traditionally, once a satellite was in orbit, it largely stayed on a fixed path, its operators reluctant to burn precious fuel. But now, the Pentagon and its adversaries, notably China and Russia, are launching satellites designed to fly in more dynamic ways that resemble aircraft — banking hard, slowing down, speeding up, even flying in tandem.

"Traditionally satellites weren't designed to fight, and they weren't designed to protect themselves in a fight," said Clinton Clark, the chief growth officer of ExoAnalytic Solutions, a company that monitors activity in space. "That is all changing now."
"Unlike dogfights between fighter jets, the jockeying-for-position encounters in orbit take place over several hours, even days," the article points out.

But it also notes that recently Germany's defense minister "complained about a Russian satellite that had been flying close to a commercial communications satellite used by the German military. 'They can jam, blind, manipulate or kinetically disrupt satellites,' he said."

In 2023 Slashdot covered a battery-swapping startup that promised to give EVs a full charge in about the same time it takes to fill a tank of gas.

They just filed for bankruptcy, reports Inc: Ample was founded in 2014 with a goal of "solving slow charging times and infrastructure incompatibility" for commercial EV fleets such as those in logistics, ride-hailing, and delivery, the filing states. To-date, Ample has raised more than $330 million across five rounds of funding to finance research and development and deployment. Rather than tackling fast charging, its strategy involved developing "fully autonomous modular battery swapping," capable of delivering a fully charged battery in just five minutes. The technology requires purpose-built "Ample stations" that look a little like carwashes. A car is guided into the bay and elevated on a platform. A robot then identifies the location of a car's battery module, removes it, and replaces it with a charged module, Canary Media reported.

The company also boasts partnerships with Uber, Mitsubishi, and Stellantis, and notes it has deployed its technology — or is pursuing deployment — in San Francisco, Madrid and Tokyo. Even so, it ran up against funding issues. In its filing, Ample attributed its bankruptcy to macroeconomic and industry headwinds, such as "severe supply chain disruptions," "contraction in both public and private investment in renewable energy" and the "reduction, delay, or redirection of government incentives intended to accelerate EV adoption." The filing notes that regulatory and permitting delays slowed its launch in international markets, after which access to capital foiled its scaling efforts. The company eliminated all but two full-time, non-executive employees after formerly employing about 200...

Electrek noted that Ample is the second battery swapping startup to go bankrupt after California-based Better Place in collapsed in 2013 amid financial issues related to how capital intensive it was to build infrastructure, Reuters reported. And Tesla briefly pursued the concept, building a station in California, before ditching the idea altogether.
Ample "claimed to have designed autonomous battery swapping stations that would be rapidly deployable, cheap to build, and could adapt to any EV design with a modular battery which would be easy for manufacturers to use," notes Electrek's article: Where this bankruptcy leaves Ample's technology is unclear. Another company could snap it up and try to do something with it, if they find that the technology is real and useful. Ample had gotten investments and partnerships with Shell, Mitsubishi and Stellantis, for example, so the company wasn't alone in touting its tech. Or, it could just disappear, as other EV battery swapping plans have before...

That's not to say that nobody has been successful at at implementing battery swap, though. NIO seems to be successful with its battery swapping tech in China, though the company did miss its 2025 scaling goals by a longshot. But as of yet, this is the only notable example of a successful battery swap initiative, and it was done by an automaker itself, rather than a startup claiming to work for every automaker.
Electrek's writer is "just not bullish on battery swapping as a solution in general. Currently, the fastest-charging vehicles can charge from 10-80% in about 18 minutes. While that's longer than 5 minutes, it's not really a terrible amount of time to spend during most stops."

Plus, if cars come and go in 5 minutes instead of 18 minutes, "then you're going to have more than triple the throughput at peak utilization." And Ample's prices would be about the same as normal EV quick-charging prices...

TikTok's owner ByteDance has signed a deal creating a U.S.-focused joint venture majority-owned by American and global investors, allowing the app to avoid a U.S. ban while ByteDance retains a minority stake. The BBC reports: Half of the joint venture will be owned by a group of investors including Oracle, Silver Lake and the Emirati investment firm MGX, according to a memo sent by chief executive Shou Zi Chew. The deal, which is set to close on January 22, would end years of efforts by Washington to force ByteDance to sell its US operations over national security concerns. It is in-line with a deal unveiled in September, when US President Donald Trump delayed the enforcement of a law that would ban the app unless it was sold.

TikTok said in the memo that the deal would enable "over 170 million Americans to continue discovering a world of endless possibilities as part of a vital global community." Under the agreement, ByteDance will retain 19.9% of the business, while Oracle, Silver Lake and Abu Dhabi-based MGX will hold 15% each. Another 30.1% will be held by affiliates of existing ByteDance investors, according to the memo.

President Trump's closure of the de minimis customs loophole in May -- which previously allowed Chinese packages valued under $800 to enter the U.S. duty-free -- has redirected a flood of cheap goods toward Europe, where similar exemptions for packages under $175.8 in the EU and $180 in the UK remain intact.

The shift has been swift: exports of low-value Chinese packages to the U.S. have dropped more than 40% since May, according to Chinese customs data, and the EU has this year overtaken the U.S. as the largest market for China's roughly $100 billion cheap package trade.

Shipments to Hungary and Denmark have quadrupled, and those to Germany, France, and the UK have risen 50% or more. Temu has recorded seven straight months of double-digit U.S. sales declines, per Consumer Edge data tracking credit and debit card transactions. Its European sales, on the other hand: up 56% in the EU and 46% in the UK since May compared to a year ago. The EU agreed last week to impose a $3.5 fee on imported small packages starting in July and to close the de minimis exemption entirely by 2028. The UK plans to follow in 2029.

The television industry's brightness war may have hit its inflection point in 2025, the year TCL and Hisense released the first consumer TVs capable of 5,000 nits under specific settings -- a figure that would have seemed absurd not long ago when manufacturers struggled to reach 2,000 nits. LG introduced Primary RGB Tandem OLED technology, moving from a three-stack panel design to a four-stack red-blue-green-blue configuration that the company claims can achieve 4,000 nits. The technology appears in the LG G5, Panasonic Z95B and Philips OLED950 and OLED910.

RGB mini-LED also emerged as a new category. The technology uses individual small red, green and blue LED backlights instead of white or blue LEDs paired with quantum dots. Hisense demonstrated it at CES 2025, TCL announced its Q10M for China, and Samsung unveiled its own version called micro-RGB. These sets range from $12,000 to $30,000. Sony has confirmed it will debut RGB TV technology in spring 2026. HDR content is currently mastered at a maximum of 4,000 nits. The situation echoes the audio industry's loudness war, The Verge points out, which peaked with Metallica's heavily compressed Death Magnetic in 2008.

iRobot, the Bedford, Massachusetts-based company that brought the Roomba vacuum cleaner into American homes over its 35-year history, filed for bankruptcy on Sunday and will be acquired by Picea, its Chinese contract manufacturer that also produces competing household devices.

The Wall Street Journal's editorial board placed blame for the company's demise on the Federal Trade Commission under Chair Lina Khan, which opposed Amazon's $1.7 billion bid to acquire iRobot. That deal collapsed in January 2024 amid regulatory pressure from both the FTC and European antitrust authorities. Senator Elizabeth Warren and other progressives had urged Khan to block the acquisition, arguing in a September 2022 letter that Amazon is "'almost universally recognized' as the leader in warehouse and fulfillment robotics space" and that the deal "would open up a new market to Amazon's abuses."

After the deal fell through, iRobot cut 31% of its workforce and moved "non-core engineering functions to lower-cost regions." The company had shifted production to Vietnam to reduce its exposure to China but was hit by tariffs under Trump's Liberation Day trade measures -- initially 46%, later reduced to 20%. iRobot said the trade uncertainty made it difficult to operate.
