As robotics has advanced, industry has steadily adopted more robots to automate away many kinds of grunt work. More than 540,000 new industrial robots were installed worldwide in 2023, taking the number of total industrial robots active to above 4 million, per IFR. Industrial robots typically excel at repetitive tasks, but they find it challenging to perform precise tasks, handle delicate materials, and adjust to changing conditions — a robot in a restaurant’s kitchen would get in the way more than be helpful, for example. That is why many industrial processes are still manual. South Korean startup RLWRLD aims to solve this problem with a foundational AI model that it has built specifically for robotics by combining large language models with traditional robotics software. The company says this model will enable robots to make quick and agile movements and perform some amount of “logical reasoning” as well. “Using RLWRLD’s foundation model, processes that require a lot of manual work can be completely automated by learning and copying human expertise, making work environments more efficient,” Jung-Hee Ryu, founder and CEO of RLWRLD, said in an exclusive interview with TechCrunch. The startup is now coming out of stealth with 21 billion KRW (about $14.8 million) in seed funding. The round was led by venture capital firm Hashed, and Mirae Asset Venture Investment and Global Brain also invested. Notably, RLWRLD has attracted a long list of big strategic investors — Ana Group, PKSHA, Mitsui Chemical, Shimadzu and KDDI from Japan; LG Electronics and SK Telecom from Korea; and Amber Manufacturing from India. RLWRLD said the seed funding will be used to fund proof-of-concept projects with its strategic investors; secure computing infrastructure like GPUs, purchase robots, and devices to collect extensive data; and hire top research talent. The startup will also use the new money to develop advanced hand movements involving five-fingers — a capability that’s not yet been demonstrated by its competitors like Tesla, Figure AI and 1X, Ryu said. image credits: RLWRLD Ryu said RLWRLD is also working with its strategic investors to explore ways to automate different human-centric workflows using its AI model. They are together preparing a humanoid-based autonomous action demonstration, scheduled for later this year, Ryu said. In addition, the company is working to develop a platform that can support various kinds of robots, including industrial, collaborative, autonomous mobile robots and humanoids. Founded in 2024, RLWRLD is Ryu’s third startup. His second startup, Olaworks, was acquired by Intel in 2012, and eventually became Intel’s Korea R&D center within its computer vision division. And in 2015, he founded a startup accelerator, Future Play, that focuses on deep tech companies. When asked what inspired him to start a new company again, Ryu said he noticed how quickly AI startups were increasing in number in the U.S, Europe and China, while comparable AI startups in Korea and Japan were relatively absent. He spoke with over 30 AI professors from Korea and Japan about their challenges — everything from the lack of infrastructure like data and GPUs, and the obstacles that discouraged them to launch a venture — and the opportunities available. “I determined that it would be strategically beneficial to prioritize robotics foundation models (RFM) over the technologically saturated field of LLMs, capitalizing on Korea and Japan’s notable global strengths in manufacturing,” he said. Soon afterwards, he brought on board six professors from top-ranked institutions in South Korea, including KAIST, SNU, and POSTECH, along with their research teams, to launch RLWRLD. RLWRLD isn’t alone in tackling this problem. Startups like Skild AI and Physical Intelligence are building similar foundational models for robotics, as are larger firms like Tesla, Google DeepMind, and Nvidia. But Ryu believes his startup has a good start, as it already has the AI and robotics experts it needs to develop foundational models for robotics, as well as humanoid robots with high degree of freedom (DoF). “Additionally, [such companies] typically rely on low-DoF robots such as two-fingered grippers. RLWRLD has already secured a high-DoF reference robot, and therefore expects superior performance outcomes,” he said. Ryu also said that thanks to its strategic investors, RLWRLD can quickly gather valuable data from manufacturing sites located nearby. In 2024, a report indicated that Japan and South Korea collectively accounted for 9.2% of worldwide manufacturing production. RLWRLD aims to generate revenue as early as this year through proof-of-concept (PoC) projects and collaboration demonstrations with strategic partners. The startup’s long-term goal is to cater to factories, logistics centers, and retail stores, and even robots that can be used in domestic environments to help with household chores. In the meantime, the priority is to target industrials since they are willing to pay the most and have strong demand for automation. The startup has 13 employees.

I am trying to recreate an effect where the slash of a weapon moves part of the image of the current scene. For reference: https://youtu.be/kWXAiU0dpPk Part of the image on screen seems to just be copied, pasted and moved slightly to the side before sliding back to the original location when taking a closer look. It’s quit noticable when looking at the hat and chain. I tried to use a Shader Graph to recreate this effect but unfortunatly my experience is rather limited and I didn’t realy manage to get anywhere. I’d greatly appreciate if someone here could help me recreate this effect or just give some general Tipps since I am new to creating VFX. *the reference is from the game Dead Cells using the weapon Queen’s Rapier 1 post - 1 participant Read full topic

Legal and IT experts have made submissions to the government’s call for views on the current rules around the use of computer evidence in court, which closes today. The wider public understanding of the Post Office Horizon scandal, which saw innocent subpostmasters jailed based on flawed evidence from an accounting system, forced the government to look again at a controversial law which presumes computers work correctly. The scandal saw hundreds of subpostmasters blamed, prosecuted and convicted of crimes after losses appeared on the accounting system used in branches. The figures produced by the Horizon system, which is supplied by Fujitsu and used in thousands of branches, was presumed to be accurate in court. But a 2018 High Court case proved that Horizon errors caused phantom losses that subpostmasters were blamed and punished for. Hundreds of people who were prosecuted based on the flawed evidence have had their convictions overturned. In January, the Ministry of Justice issued a 12-week call for evidence as it examines the role of computer evidence in the criminal justice system to prevent another Post Office scandal. The deadline for evidence closes today (15 April). In 1999, a presumption was introduced into law on how courts should consider electronic evidence. The rule followed a Law Commission recommendation that courts should presume a computer system has operated correctly unless there is explicit evidence to the contrary. This replaced Section 69 of the Police and Criminal Evidence (PACE) Act 1984, which previously stated that computer evidence should be subject to proof that it was operating properly. Read more about the rules on computer evidence Although there have been calls for many years for reform from the likes of former lawyer Stephen Mason, it was the Post Office Horizon scandal which finally persuaded the government to act. Mason, who is submitting his recommendations, said: “What I have called for is the setting up of either a judicial rules body or a group of people to write a code of practice for judges and lawyers.” He said this would be something like the rules of court or judicial rules which he says need to be “updated regularly by people that know what they are talking about”. In its submission to the call for evidence, BCS, The Chartered Institute for IT, said: “The presumption that computer-generated evidence is inherently reliable is increasingly unfit for purpose in modern criminal prosecutions.” It said the Post Office Horizon scandal illustrates this. “At present, rebutting the presumption of computer evidence is exceptionally difficult,” added the BCS. “It has been shown that defendants in cases like Horizon have struggled to access crucial system logs, error reports, and documentation that could undermine the assumed reliability of the evidence. Additionally, some of the lower courts often lack the specialised technical expertise required to scrutinise complex software and digital data, meaning that challenges to the reliability of computer evidence must overcome both procedural and substantive hurdles that favour the status quo.” The Law Society said due to the increased complexity of technology the law should not assume that computers are flawless. In its submission to the government’s call for evidence it said existing laws must keep pace with technological advances or public confidence in the justice system could be damaged. Richard Atkinson, president of the Law Society said: “Given the increasing complexity of technology, we should not assume computers are flawless. “To ensure that the use of computer evidence does not lead to miscarriages of justice, there should be assurance, regular review and disclosure of the system’s technical standards and performance across the board. Although this call for evidence relates only to criminal proceedings, the government should consider applying similar safeguards to computer evidence used in civil cases too.” He added: “While innovation can bridge existing gaps of unmet legal needs, it is important that use of technology in the justice system is fair, transparent and reliable. Any proposals put forward should prioritise justice as a vital public service affecting every single member of society.” Computer Weekly first exposed the scandal in 2009, revealing the stories of seven subpostmasters and the problems they suffered due to the Post Office Horizon accounting software - the most widespread miscarriage of justice in British history.

Portable power stations are a great way to take power with you when out and about -- like a power bank, only much bigger. Whether you're hiking, camping, or going on an RV vacation, there's a power station to suit your needs.These units store varying amounts of power depending on capacity, and can be recharged using multiple power sources, from a standard AC outlet, a car's 12V port, to eco-friendly solar panels! And unlike traditional generators, they require minimal maintenance, are safer to use both indoors and outdoors -- yes, there are IP-rated water- and dust-resistant units -- and are built to last for years with little hassle.  What is the best portable power station right now? Over the past few years, I've tested over 100 different power stations to find out which ones truly stand out. My top pick right now is the Jackery Solar Generator Kit 4000.

Products like smartphones, laptops, and TVs may become more expensive as companies rethink global supply chains and weigh the cost of shifting production.Devices such as power stations are predominantly manufactured in these regions, and are now subject to tariffs as high as 54% on Chinese imports and 46% on Vietnamese goods. As a result, consumers may see price increases of approximately 20% on these items. Manufacturers are exploring options like relocating production to countries with lower tariffs, but such shifts are complex and may not provide immediate relief. In the short term, shoppers should anticipate higher costs for headphones and wearables due to these trade policies.Right now, it looks like some tech may be exempt from the issued tariffs, but since it's always changing and developing, we are keeping an eye on it and will update you on the latest.Also: Tariff exemptions for electronics offer a break for tech - but not for longWho are portable power stations for? In my experience with power stations, I've identified three distinct groups of people who typically purchase these devices.Backup Power Seekers: The first group consists of individuals looking for backup power solutions in case of outages. These users often seek systems that can provide power for a few hours or even days, depending on the frequency of power interruptions in their area. Their options range from compact units that can easily slide under a bed or fit in a cupboard to larger systems that occupy more space but offer greater capacity.Off-Grid Enthusiasts: The second group includes those who aim to save money and gain a degree of off-grid capability by harnessing solar energy. By using one or more solar panels, they can generate power for their homes or electric vehicles (EVs). I've noticed a growing trend of people investing in these systems. While the financial savings may not be immediate, a well-designed solar setup can ensure long-term benefits and sustainability.Portable Power Pros: Finally, there are individuals who need portable power solutions for activities like camping, working remotely, or traveling in an RV. The versatility of being able to charge these units from solar panels, a vehicle's electrical system, or any available AC outlet is a significant advantage. These power stations can support a variety of devices, including home appliances, laptops, drones, cameras, and even medical equipment like CPAP machines.Power stations represent a modern evolution of traditional gasoline generators, offering numerous benefits. They are typically smaller, quieter, and free from the unpleasant odors associated with gasoline. Additionally, they can be safely operated in confined spaces. However, there are drawbacks to consider. One of the most significant challenges is the reliance on sunlight for recharging. Without ample sunlight, maintaining an off-grid lifestyle can become complicated. In contrast, it's much easier to stockpile gasoline than to store sunlight. As a result, there are situations where, despite the drawbacks of gasoline generators-such as their fumes, maintenance needs, and safety risks-they still reign supreme in certain applications.Understanding the different needs and preferences of power station users can help you choose the right solution for your specific requirements, whether for backup power, off-grid living, or portable energy needs.

The primary distinction between portable power stations and gasoline generators lies in their energy sources and operation. Portable power stations are equipped with batteries that are pre-charged with electricity before use. In contrast, gasoline generators rely on gasoline, which is burned in an engine to produce electricity.Gasoline Generators:Because they combust gasoline, these generators pose significant safety risks when used indoors. The burning process produces carbon monoxide, a colorless, odorless gas that can lead to suffocation. Additionally, gasoline generators create fire hazards, are often noisy, and emit unpleasant odors that can be disruptive in residential settings.Portable Power Stations:In contrast, portable power stations operate quietly, emit no fumes, and produce minimal heat. They require little to no maintenance beyond occasionally checking their charge levels. This makes them an ideal choice for a variety of settings, including indoor use and outdoor activities, without the concerns associated with gasoline generators. Show more How long will a portable power station last? Manufacturers typically offer different runtimes for lamps, refrigerators, CPAP machines, and so on, but if you want to work this out for yourself, you may need two figures. First, you need the power rating of the device you plan on running, which can usually be found on a label on the device and is measured in Watts (W). You also need to know the capacity of the power station, measured in Watt hours (Wh), which should be printed somewhere on the device. Let's say you have a device that consumes 200W and a power station that has a capacity of 2,048Wh, you can get a ballpark runtime for the device using the following equation:(2048 x 0.85)/200 = 8.7 hoursNote that the capacity of the power station is multiplied by 0.85 to account for efficiency losses.  Show more What is the difference between a power bank and a portable power station? There are four main distinctions that set portable power stations apart from power banks:Capacity: Portable power stations boast significantly larger battery capacities compared to power banks. While power banks are ideal for topping up smartphones or tablets, a power station can recharge devices multiple times due to its much greater capacity, which is typically measured in watt-hours rather than milliampere-hours (mAh).Size and Weight: Power banks are compact and lightweight, often small enough to fit in a pocket. In contrast, portable power stations are bulkier and heavier, designed to be transported by hand or wheeled from room to room, making them less convenient for everyday carry.Outlets: Power banks generally feature USB ports for charging smaller devices. On the other hand, portable power stations come equipped with AC outlets, allowing them to power a wider range of devices, including larger electronics and appliances.Charging Options: Power banks are typically charged using a USB charger, which limits their versatility. Portable power stations, however, can be charged from various sources, including standard wall outlets, solar panels, and vehicle 12V outlets, providing greater flexibility for users.

risks CT scans could cause 5% of cancers, study finds; experts note uncertainty The estimates are small and uncertain, but balancing risks and benefits is critical. Beth Mole – Apr 14, 2025 7:18 pm | 25 A CT scanner Credit: Getty | Ryan McFadden A CT scanner Credit: Getty | Ryan McFadden Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only   Learn more Computed tomography scans have become vital, even lifesaving, medical imaging for diagnosing and monitoring health conditions. But they do expose patients to ionizing radiation at levels linked to higher risks of cancer. In a new study in JAMA Internal Medicine, researchers tried to estimate what those higher risks are exactly—and although the estimates come with uncertainty, they may seem startling. Based on data from 93 million CT scans performed on 62 million people in 2023, the researchers estimated that the CT scans would lead to 103,000 future cancers. To put that in context, those 103,000 cancers would account for about 5 percent of cancers diagnosed each year, based on the current cancer rates and the current usage of CT scans. And the estimate puts CT scans on par with alcohol consumption and obesity in terms of risk factors for developing cancer. The most common types of cancers estimated to be a result of CT scans were lung cancer and colon cancer—two cancers that are becoming more common in younger people for reasons experts do not fully understand. The types of CT scans linked to the greatest number of cancers were abdomen and pelvis CT scans. The study's authors—led by epidemiology and biostatistics researchers at the University of California, San Francisco—concluded that doctors should use CT scans when they can be justified and at optimized doses to balance the risks and benefits. "CT is frequently lifesaving, yet its potential harms are often overlooked, and even very small cancer risks will lead to a significant number of future cancers given the tremendous volume of CT use in the United States," they write. Since 2007, use of CT scans has increased 35 percent, an increase not entirely explained by population growth, they note. Outside experts agreed that CT scans should be used judiciously. But, they highlighted that there is much uncertainty in the modeling, which tried to assess absorbed doses in different organs and the increased risk of site-specific cancer. While some large studies have found links between CT scans in children and young adults and increased risks of blood and brain cancers,  the risks for adults have largely been extrapolated from studies on Japanese atomic bomb survivors or people with occupational radiation exposures. Uncertainty and balancing "The estimates, while based on the best models available to the authors, are indirect, so there is considerable uncertainty about the estimates," Stephen Duffy, emeritus professor of Cancer Screening at Queen Mary University of London, said in a statement. "Thus, I would say to patients that if you are recommended to have a CT scan, it would be wise to do so." Duffy also highlighted that in the context of a person's overall risk of cancer, CT scans don't move the needle much. There were a little over 100,000 cancers linked to 93 million scans. "This amounts to around a 0.1 percent increase in cancer risk over the patient's lifetime per CT examination," he said. The lifetime risk of cancer in the US population is around 40 percent. Thus, the additional risk from CT scans "is small." Overall, when a CT scan is deemed necessary, the "likely benefit in diagnosis and subsequent treatment of disease outweighs the very small increase in cancer risk." Doreen Lau, a cancer biology expert at Brunel University of London, agreed: "The findings don’t mean that people should avoid CT scans when recommended by a doctor. In most cases, the benefit of detecting or ruling out serious illness far outweighs the very small risk of harm." Still, the rise in CT scans in recent years may suggest that doctors could cut back on their use. In an accompanying editorial, Ilana Richman of Yale University and Mitchell Katz of NYC Health and Hospitals discussed ways that doctors could make sure they're balancing risks and benefits before using CT scans, including using diagnostic algorithms and offering alternative imaging options, such as ultrasounds and magnetic resonance imaging (MRIs). "As with all complex problems, there will be no simple solution," they write. But, "educating clinicians about avoiding low-value testing and, in circumstances where alternatives are readily available, involving patients in the decision to do a CT scan may help shift culture and practice."
