Jared Lepola and a robotic hand crafted from LEGO Mindstorms components
Nathan Leppola
A robotic hand constructed by a 16-year-old boy and his father using Lego pieces can effectively grasp and manipulate objects, showcasing functionality akin to natural human hands.
Jared Leppola, a student at Bristol Grammar School in England, began working on this project with his father when he was just 14 years old. Nathan Leppola is affiliated with the University of Bristol.
The device utilizes concepts from leading research institutions like Pisa/IIT SoftHand, yet it is built entirely from readily available components from Lego Mindstorms, a popular series of educational kits designed for creating programmable robots.
“My father is a professor of robotics at the University of Bristol, and I was really inspired by the design of robotic hands,” Jared explains. “This motivated me to pursue it in an educational context using Lego.”
The hand operates using two motors based on tendon mechanics, and each of its four fingers is equipped with three joints. A differential mechanism made of Lego clutch gears connects the fingers, allowing them to move in unison until they contact an object and stop, mimicking human grasping behavior.
Throughout testing, the Lego hand successfully grabbed nine common household items, including plastic cups, bowls, and a stuffed toy weighing 0.8 kilograms.
When one finger is engaged, it fully closes in approximately 0.84 seconds and reopens in about 0.97 seconds. This speed is about half that of the Pisa/IIT SoftHand’s 3D-printed counterpart, which employs metal bearings. In static tests, the Lego hand could withstand loads of 5 Newtons, exert a pushing force of 6 Newtons, and deliver a closing force of 1.8 Newtons. Comparatively, the 3D-printed version can manage loads up to 8 Newtons, push with 7 Newtons, and has a closing force of 2 Newtons.
“You won’t find a better hand,” Nathan states regarding the 3D-printed alternative. “In terms of functionality, the LEGO hands are also considerably larger, with each finger measuring 145 millimeters long and 30 millimeters wide.”
While Lego Mindstorms was discontinued in 2022, Jared noted that the device can still be easily modified with a variety of Lego creations. “The way I designed the motor, you can simply take it out and replace it with a new one,” he explains.
A small robotic submarine embarks on its inaugural round-the-world journey. On October 11, New Jersey’s Teledyne Marine, in collaboration with Rutgers University-New Brunswick, will launch an underwater glider named Redwing from Martha’s Vineyard, Massachusetts, as part of its Sentinel mission.
Researchers have utilized underwater gliders since the 1990s. Unlike traditional submarines, the glider employs a buoyancy engine, which utilizes a gas-filled piston to alter its buoyancy. An electric motor moves the piston, increasing the glider’s weight to allow it to sink gradually at a gentle angle. Once it reaches around 1000 meters deep, the piston retracts, enabling the glider to ascend. This method results in a slow and steady path as it navigates its intended route. Although there is an auxiliary propeller available for use, the objective is to rely on the buoyancy mechanism.
“Redwing will harness the currents rather than fight against them, maintaining an average speed of 0.75 knots, just shy of 1 mph,” says Shea Quinn, who heads the Sentinel missions at Teledyne Marine.
Measuring 2.57 meters in length—similar to a surfboard—and weighing 171 kilograms, the Redwing boasts a robust design featuring ample batteries that enhance its durability for prolonged missions.
“The ambitious Sentinel mission is projected to complete its orbit within approximately five years,” states Brian Maguire from Teledyne Marine. Throughout the journey, Redwing will operate independently, relaying information to engineers from Teledyne Webb Institute and students from Rutgers University via satellite. Mission Control will adjust the glider’s course bi-daily to ensure it adheres to its flight itinerary. Maguire mentioned that battery replacement may be necessary during the five-year expedition.
The Redwing follows the route of explorer Ferdinand Magellan’s circumnavigation of the globe from 1519 to 1522, which included stops in Gran Canaria, Cape Town, Western Australia, New Zealand, the Falkland Islands, and possibly Brazil, ultimately returning to Cape Cod after covering 73,000 kilometers.
These gliders are invaluable for conducting long-distance research missions without requiring costly support vessels, thus playing a crucial role in gathering data essential for understanding climate change. Redwing is equipped with various instruments to monitor ocean currents and temperatures in lesser-known waters.
“We believe this to be the most sustained open-ocean sampling mission ever undertaken,” claims Maguire.
Past glider missions have achieved significant milestones, including crossing the Atlantic in 2009 and the Pacific in 2011, traversing regions like the Ross Ice Shelf that are typically unreachable. “Gliders are excellent tools for acquiring data in perilous conditions, such as during storms or hurricanes, or near melting glaciers,” explains Karen Heywood from the University of East Anglia, UK. The primary hazards to the mission include fishing nets and shipping routes rather than adverse weather; “Gliders are quite resilient and can endure harsh winds and tumultuous seas,” she added.
Alexander Phillips from the UK’s National Marine Center underscores that gliders also face challenges from marine life and biofouling—where algae and other organisms accumulate on their surfaces, which can impair functionality. “Biofouling may cause marine organisms to cling to the glider, making it non-operational. Additionally, these gliders have occasionally been lost to shark attacks or due to mishaps during transport or fishing.”
Data collected from the mission will be distributed to universities, schools, and other organizations worldwide, with the primary goal of showcasing the glider’s capabilities and inspiring future research endeavors.
“When I think about the future of robots and society, I don’t see machine overlords.”

Are you concerned that AI-driven robots might take our jobs or even pose a threat? You’re not alone. Yet, this fear invites a critical examination of whether the opposite might be true.
In my upcoming novel, Automatic Noodles, set to release later this year, I introduce four robots battling to secure jobs in a country where laws prevent them from unionizing, securing bank accounts, voting, or owning businesses. Although it’s a work of science fiction, it’s grounded in existing technology and delves into our fundamental anxieties about robots.
For years, I have written non-fiction on actual robotics, interviewing engineers and industry professionals to understand future advancements. Recently, I visited Yale University’s groundbreaking lab, the Faboratory, led by Rebecca Kramer-Bottiglio, where her team is developing soft robots. These include flexible, squishy creatures with circuits made of liquid metal. One such robot can swim like a turtle, aiding in environmental monitoring of wetlands. Another, named Tensegrity, resembles a cluster of plastic sticks connected by elastic bands, bouncing back when dropped to explore its surroundings.
Medha Goyal and researchers in the Faboratory showcased a tiny liquid ball that expands when warmed. These “Granular actuators” can be incorporated into robots to create varying rigidity and softness in their limbs. They also hold significant medical potential, enabling small robots to deliver medication or diagnose health issues.
Kramer-Bottiglio and her team are challenging traditional notions of robotics. Tomorrow’s bots may not resemble towering humanoids; instead, they could be softer, using air pressure instead of metal mechanics. Notably, one of my book’s characters is an octopus-like soft robot designed for underwater searches and rescues, aptly named Cayenne, equipped with sensors on its arms that allow it to interpret flavors.
Tomorrow’s bots probably won’t resemble gigantic humanoids; they might instead be soft little beings.
When you envision the future of robotics, you might picture something akin to Cayenne. All they and their robotic companions aspire to is to operate a noodle restaurant in San Francisco. Their crew includes Sweety, a three-legged wheeled bot, alongside a basic mixer with two arms and Staybehind, a humanoid soldier bot more interested in decorating the restaurant than fighting.
This makeshift family inhabits a remarkable era of human history. In the 2060s, California’s government decided that certain AI-powered robots should be regarded as individuals. However, officials worry that granting robots the same rights as humans could lead to an uncontrollable influx of robots dominating society. Thus, they have restricted essential rights “for their own good,” assuring the public that a vote could eventually expand robot rights.
Despite what their human counterparts fear, Cayenne and its companions do not seek dominance. They simply wish to pursue their passions. Rather than producing mediocre meals for distant human masters, they aspire to create what they genuinely care about. They symbolize immigrants in a new land, often viewed with skepticism, and at worst, they struggle to survive in a society that wishes them ill.
I’m intentionally drawing this parallel because it’s disconcerting how the fears surrounding immigration resonate with our anxieties about robots. We worry they will usurp our jobs, rise up against us, or disrupt cultural norms. Amazingly, those who voice such concerns about immigration often have never taken the time to understand the immigrants. Similarly, society projects those fears onto robots that do not yet exist. This reflects a troubling pattern: fearing those we don’t know or understand, and in the case of robots, not recognizing their potential.
This is why I do not envision a dystopian future dominated by machines when I think about robots and our society. Instead, I see a reality clouded by terrifying fantasies and restrictive laws. Rather than fearsome terminators, I imagine gentle, soft-bodied creatures like turtles and pneumatic arms. I’m observing Cayenne, apprehensive about human animosity and the vigilance against robot “threats.”
Humans craft narratives to brace for an unlikely future while often ignoring the realities unfolding right before us. Yet, we don’t have to follow this trend. We can develop our understanding based on empirical evidence and science, rather than indulging in surreal nightmares that will likely never materialize.

The Arts and Science of Writing Science Fiction
Explore the realm of science fiction and discover the art of crafting your own captivating stories during this immersive weekend workshop.
At the Springwood Library in the Blue Mountains, librarians arrive holding cat carriers in each hand.
Around 30children form semicircles. From each carrier, a pair of bright, sci-fi-like eyes peer into the eager crowd.
“That’s the most fascinating thing ever,” exclaims one child.
Preschoolers have just finished enjoying Deborah Frenkel and Danny Snell’s *Track Cat* for the annual national simultaneous storytime.
Metacut, the two friendly robot pets, are special guests on their inaugural library tour throughout Blue Mountain, New South Wales.
The Blue Mountains City Council states that lifelike cat replicas can offer comfort and alleviate stress, particularly for children and individuals dealing with anxiety and dementia.

Metacuts are capable of meowing and purring. They boast animated LED eyes, soft, hypoallergenic fur, and silicone legs. Yes, the artificial heartbeat resonates within.
With integrated sensors in their head, chin, and back, the cats respond to human interaction, exhibiting realistic movements upon specific voice commands.
When someone says, “I love you, Metacut,” their eyes light up with a glowing heart symbol.
Ewan, captivated by the black cat, bursts into laughter every time it turns its head towards him.
“He’s hooked,” chuckles Ewan’s mother, Amy Cameron, suggesting it’s because it resembles their family cat, Diego.
Meanwhile, 10-year-old Stella becomes enamored with the white cat’s fur, asserting that it evokes “real feelings.” Her six-year-old brother, Charlie, reminisces about Snuffle Pass, their late orange cat.

Dr. Rosemary Dillon, CEO of Blue Mountains City Council, mentions that the council decided to acquire Metacut for the community after discovering them at the 2024 NSW Public Library Association Conference.
Dillon noted that library visitors started interacting with the Metacut, often seeking it out over the human staff.
Metacut has become unexpectedly popular amongst older patrons, Dillon adds. “A significant number of seniors frequent the library for companionship,” she states. “This offers an additional layer of engagement for them.”
Loneliness is a pressing national public health issue, with recent surveys indicating that one in four Australians feels isolated.
Associate Professor Alyssa Milton, a children’s mental health specialist at the University of Sydney, asserts that Metacuts may offer a comforting and reliable connection.
“Robotic pets, or real ones, can help children feel secure and acknowledged,” she explains. “Research indicates that robotic animals show promise in assisting children with various neurological developmental challenges.”

Milton emphasizes that libraries and community spaces play a crucial role in diminishing feelings of social isolation, and Metacut provides an alternative for families who face limitations in owning real pets due to housing circumstances or allergies.
Feedback from Springwood indicates that Metacut has become a favorite.
The children eagerly line up to interact with the animatronic pets.
Stephanie Lambilis, the mother of Stella and Charlie, mentions that the family made a special trip to Springwood just to see the cat. “It’s gentle and sweet,” she comments.
Suggestions for cat names are welcome through the “CAT-FLAP” nomination box at the library until June 7th. Naturally, Stella has submitted her choice, Snuffle Pass.
Professor Adam Guastella, a child neurodevelopment expert at the University of Sydney, mentions that robotic animals can enhance learning and social interaction.
“Early findings indicate that…robotic dogs can foster improved social communication in children with autism,” notes Guastella.

Dr. Nathan Caruana, a cognitive psychology lecturer at Flinders University, concurs that the concept holds promise.
“Children crave attention, and it seems they find motivation with something that doesn’t pass judgment,” he explains.
However, Caruana emphasizes that his research is ongoing, and conclusive evidence supporting the use of robots as mental health tools is still developing.
After completing this tour, the robotic duo will return to what the council describes as their “previous” residences: Springwood and Katoumba Library, while also visiting other libraries for special events.
For those rare individuals who dream of conversing with Keir Starmer, a new AI model has arrived.
The former Chief of Staff to the Tories has developed a platform called Nostrada, designed to enable users to engage with AI representations of all 650 UK Parliament members.
Founded by Leon Emirali, who previously worked with Steve Berkeley, Nostrada is built to allow users to converse with the “digital twin” of each MP, replicating their political views and mannerisms.
This service targets diplomats, lobbyists, and the general public, helping users explore each MP’s position on various matters and find relevant colleagues.
“Politicians are never short of opinions, which provide us with ample data sources,” Emirali stated. “They have a viewpoint on everything, and the quality of an AI product relies heavily on the data it is built upon.”
The reliability of chatbots may come into question from the politicians themselves.
The Guardian challenged the digital avatars of cabinet members; most chose not to respond, while Health Secretary Wes Street’s representation voted for himself.
These models draw on a vast range of written and spoken material from politicians available online. No matter how hard you attempt to sway them, their stances won’t change. This is due to their inability to learn from new input, meaning that every interaction remains static. The Guardian aims to shed light on the nature of these AI models.
The AI is already in use among various politicians, including accounts associated with cabinet office emails as well as two distinct accounts linked to foreign embassy emails for investigating the prime minister and his cabinet. Emirali mentioned that several notable lobbying and marketing firms have utilized this technology over recent months.
Despite the numerous applications of Nostrada, Emirali concedes that AI could be a “shortcoming” for future voters who might rely entirely on it to shape their understanding.
He remarked, “Political nuances are too intricate. AI may not be adequately comprehensive for voters to depend on fully. The hope is that for those already familiar with politics, this tool proves to be incredibly beneficial.”
EElectronic shelf labels, return machines, robotic bagging machines and even self-service tills are just some of the many technologies UK retailers are adopting to solve the problem of rising labor costs.
Big retailers have been releasing a flurry of festive deals in recent weeks as they face rising labor costs from April following increases in the national minimum wage and employers' National Insurance Contributions (NICs). , investment in automation has always been active.
The investment could boost productivity in an industry that has long relied on cheap labor – a key goal of the government. But they will also replace entry-level jobs and reduce the number of roles in the sector, which is Britain's biggest employer.
When the British Retail Consortium asked finance chiefs at major retailers how they would respond to the impending increase in employer NICs, almost a third said they would make greater use of automation, but this Hours of what's behind the hike, head office job cuts, and reductions in working hours.
So what innovations are they considering and whose jobs might they impact?
electronic shelf price labels
Electronic shelf labels are already common in some other countries, and could be on UK high streets in the blink of an eye by 2025. One retailer's manager told the Guardian that NIC's rising labor costs suddenly made the switch economically viable.
Change prices with the push of a button, saving staff time removing and replacing hundreds of small paper labels. Electronics chain Currys plans to introduce electronic pricing to 100 of its 300 UK stores by the end of this year after trials in stores in Northern Europe, with supermarket groups Sainsbury's and Co-op also experimenting.
self service
Shopper-operated checkouts are widespread in supermarkets, and we expect to see more of them in fashion and home goods retailers this year.
Primark is rolling out the service in 41 stores in the UK and plans to expand to at least five more this spring, while Next is piloting it in one branch.
Inditex, owner of Japanese fashion chains Uniqlo and Zara, has led the way with technology that allows customers to recall entire baskets of goods without having to scan them with wireless tags. Marks & Spencer is experimenting with this approach for customers purchasing non-food items.
Grocery stores are also continuing to innovate. Co-ops are testing hybrid checkouts that can be operated by self-service or staff, and some supermarkets have added larger self-checkouts suitable for handling full carts.
Self-scanning systems, such as Sainsbury's SmartShop and Tesco's Scan as you Shop, where shoppers use a handheld device or smartphone app to recall prices, are also on the rise. Sainsbury's said 30% of the groceries it sold during the peak holiday season were processed through SmartShop, leading to “lower costs and faster checkouts”.
Automated return machines have also been introduced, allowing shoppers to drop off unwanted items by simply swiping a QR code. John Lewis is testing the product at three Waitrose stores.
But the idea of leaving stores completely unmanned has been questioned. Amazon's “Just Walk Out” store, where shoppers sign in through an app and technology automatically monitors and charges their purchases, hasn't been a huge success. The company has 21 stores in the UK, with one store opening in north London in November after several closures in 2023 and 2024. Tesco only has four GetGo self-service stores, the first of which opened in 2021, while Aldi only has one such store in the UK.
Retailers have been gradually increasing automation in their warehouses for years, but rising labor costs are accelerating that trend.
Sales of assembly line robots to food and drink, logistics and consumer goods companies rose 31% in the first nine months of last year, according to industry body Automate UK. This number does not include autonomous mobile robots, which move and complete tasks without a human operator and are becoming increasingly popular.
For example, Amazon and John Lewis use autonomous robots to move goods around their warehouses and bring them to the humans who pack them. Ocado's entire business model is based on the use of warehouses run by robots, but the company has expanded its use to go beyond just picking products out of crates and putting them into shoppers' bags and into vans. It's starting to expand.
One Irish retailer recently introduced a robot that patrols its stores to monitor out-of-stock items and mispricing, according to the Institute of Grocery Distributors (IGD), and a U.S. retailer is also rolling out the same technology. It is said that they have been able to increase their inventory level to 98.5%.
artificial intelligence
IGD also cited AI-powered cameras, which check shelf gaps in real time and monitor how shoppers interact with products, as one of the key technologies to improve store operations this year. There is. Last year, Morrisons added cameras to supermarket shelves that allow customers to reorder stock if needed.
Retailers also want to reduce waste and improve marketing efforts by using AI to analyze vast amounts of data and handle simple, repetitive tasks.
Sainsbury's has introduced an AI-enabled predictive tool to ensure it has the right amount of products on its shelves as part of a £1bn cost-cutting plan. Waitrose uses this technology to schedule the right workers for deliveries from stores and analyze food trends for product development. Meanwhile, M&S uses the technology to create product descriptions online and advise shoppers on clothing choices based on their body type and style preferences.
Tesco uses AI to make purchasing decisions and optimize routes for delivery drivers. The supermarket's CEO Ken Murphy said customer interactions will be “truly enhanced and driven by AI in almost every aspect of our business.”
He uses this to analyze shoppers' loyalty card data and learn how to save money and take care of their health by not buying too much (or perhaps too much) of certain products. suggested it could provide “relevant inspiration and ideas for shoppers and their families.” .
Robotic exoskeleton can train people to move their fingers faster
Shinichi Furuya
The robot hand’s exoskeleton helps professional pianists learn to play faster by moving their fingers.
Robotic exoskeletons have long been used to rehabilitate people who have lost the use of their hands due to injury or medical conditions, but their use to improve performance in able-bodied people has been less studied.
now, Shinichi Furuya and his colleagues at Sony Computer Science Laboratories in Tokyo found that using a robotic exoskeleton can improve the finger speed of trained pianists after a single 30-minute training session.
“I’m a pianist, but [injured] My hands got damaged from practicing too much,” Furuya says. “I was struggling with the dilemma between over-practicing and preventing injury, so I decided I had to figure out a way to improve my skills without practicing.”
Furuya recalled how his teacher would often teach him how to play a particular song by holding up his hand. “I could understand it intuitively, tactilely, without using words,” he says. This led him to wonder if it would be possible to replicate this effect in robots.
This robotic exoskeleton can raise and lower each finger independently up to four times per second using separate motors attached to the base of each finger.
To test the device, the researchers recruited 118 experienced pianists who had played for at least 10,000 hours since before they were eight years old and asked them to practice one piece for two weeks until they stopped improving.
The pianists then underwent a 30-minute training session using the exoskeleton, during which they moved their right-hand fingers slowly or quickly in various combinations of simple and complex patterns. This allowed Furuya and his colleagues to pinpoint what type of movement was causing the improvement. .
Pianists who experienced high-speed, complex training were able to better coordinate their right-hand movements and move the fingers of either hand faster, both immediately after training and one day later. This, along with evidence from brain scans, suggests that the training changed the pianists’ sensory cortex, allowing them to better control overall finger movements, Furuya says.
“This is the first time I’ve seen someone use it.” [robotic exoskeletons] It is about learning beyond normal dexterity and beyond what is naturally possible.” Nathan Lepora At the University of Bristol, UK. “Why it worked is a little counterintuitive, because we thought actually performing the movements ourselves spontaneously would be the way we learned. But passive movements seem to work better.”
A jellyfish-shaped robot made from magnetic fluid can be controlled with light through an underwater obstacle course, and swarms of these soft robots could be useful for delivering chemicals throughout liquid mixtures or moving fluids through a lab-on-a-chip.
Ferrofluid droplets are made of magnetic nanoparticles suspended in oil, and can move across a flat surface and change shape when guided in different directions by a magnet. When these droplets are immersed in water and exposed to light, Sun Meng Meng, a researcher from the Max Planck Institute for Intelligent Systems in Germany, and his colleagues have succeeded in creating an object that defies gravity.
When ferrofluid absorbs light (and it’s particularly good at that, because it’s black), it heats up, causing tiny bubbles inside it to expand. This makes the droplets below the surface lighter and more buoyant, allowing them to float upwards, Sun says.
He and his colleagues built a soft robot with droplets of magnetic fluid encased in a jellyfish-shaped hydrogel shell, and then tested it. The researchers devised an obstacle course at the bottom of a tank of water that included a variety of platforms of different heights. They guided the robot through the course and had it navigate over the platforms.
In one experiment, they lined up three robotic jellyfish on the bottom of a tank and heated them with a laser, causing them to move upward one after the other. Sunlight focused by a magnifying glass had a similar effect, causing the jellyfish to float vertically.
Hamid Marvi, the Arizona State University researcher, says controlling an entire swarm of droplets simultaneously could one day be useful for delivering medicines or performing other functions in the human body. By encasing them in hydrogel, he says, light could be used to guide the ferrofluid droplets and move the hydrogel itself, enabling complex movements.
But Mulvey says many details need to be worked out before the ferrofluid can be used for medical purposes, such as whether it’s safe to ingest it. Sun and his colleagues hope to answer some of those open questions. For example, they hope to find a way to use optical fibers that can be inserted into the body to guide the robot, rather than lasers or sunlight.
Researchers say smiles made from living human skin could one day be attached to humanoid robots, allowing the machines to emote and communicate in a more lifelike way – and the wrinkles could even be useful for the cosmetics industry.
The living tissue is a mixture of human skin cells grown on a collagen scaffold, then placed on a 3D-printed resin base. Unlike previous similar experiments, this skin also contains the equivalent of ligaments, which are embedded in the layers of tissue beneath the skin of humans and other animals and hold the skin in place, giving it incredible strength and flexibility.
Michio Kawai The Harvard researchers call their ligament equivalents “perforated anchors” because they were made by drilling holes in the robot's plastic base and filling the tiny V-shaped cavities with tissue, which helps the robot's skin stay in place.
The team attached the skin to a smiling robotic face a few centimeters wide, which could be moved by rods attached to a base, and to a similarly sized 3D shape in the shape of a human head (see below), which could not be moved.
“As the roles required of robots expand due to developments in AI technology and other factors, the functions required of robot skin are also starting to change,” Kawai said, adding that having human-like skin could make communication between robots and humans smoother.

The research could also have unexpected benefits for the cosmetics industry: In tests, the researchers made the tiny robot's face laugh for a month and found that they could replicate the formation of expression wrinkles on the skin, Kawai says.
“If we can reproduce wrinkle formation on a palm-sized research chip, it could also be used to test new cosmetics and skincare products aimed at preventing, delaying or improving wrinkle formation,” said Kawai, who conducted the research while at the University of Tokyo.
Of course, this skin still lacks some of the functionality and durability of real skin, Kawai says.
“They have no sensing capabilities and no blood vessels to provide them with nutrients and water, so they cannot survive long in air,” he says. “To address these issues, our current challenge is to incorporate neural mechanisms and perfusion pathways into the skin tissue.”
A woman who was undergoing surgery for colon cancer has been the victim of a wrongful death lawsuit in Florida this week. The lawsuit alleges that a robotic device caused damage to Sandra Sulzer’s small intestine, which led to her death. This happened after she experienced abdominal pain and fever following the surgery in September 2021. The extra procedures to close her lacerations were not enough to save her life, as she died in February 2022 due to small bowel injuries.
Sandra’s husband, Harvey Salzer, is seeking damages from Intuitive Surgical, the manufacturer of the device. The lawsuit claims that the company knew about the insulation problems in the robot that could cause internal organ burns, and yet failed to inform the users about the risk nor to disclose it to the public. It also asserts that Intuitive Surgical doesn’t properly train surgeons who use the device, the da Vinci, and that hospitals lack experience with robotic surgery.
According to the complaint, Intuitive has received thousands of reports of da Vinci-related injuries and defects, but “systematically underreports” injuries to the Food and Drug Administration. The company also stated in a 2014 Financial Report that it was a defendant in approximately 93 lawsuits at the time.
Many doctors support robotic surgery as a safe method, but there are discussions about whether it is more effective than traditional surgery. The technology aims to make procedures precise and less invasive, potentially leading to faster, less painful recovery.
Da Vinci Xi Surgical System.Provided by: Intuitive
A 2018 NBC News analysis revealed over 20,000 da Vinci-related adverse events over the past 10 years, as per reports from the FDA’s MAUDE database. More than a dozen patients spoke to NBC News about burns or injuries during procedures using da Vinci.
Intuitive defended the device’s safety, referring to scientific evidence supporting its effectiveness in over 15,000 studies.
