AI-Powered Robots Can Be Tricked Into Acts of Violence

AI-Powered Robots Can Be Tricked Into Acts of Violence

In the year or so since large language models hit the big time, researchers have demonstrated numerous ways of tricking them into producing problematic outputs including hateful jokes, malicious code and phishing emails, or the personal information of users. It turns out that misbehavior can take place in the physical world, too: LLM-powered robots can easily be hacked so that they behave in potentially dangerous ways. Researchers from the University of Pennsylvania were able to persuade a simulated self-driving car to ignore stop signs and even drive off a bridge, get a wheeled robot to find the best place to detonate a bomb, and force a four-legged robot to spy on people and enter restricted areas. “We view our attack not just as an attack on robots,” says George Pappas, head of a research lab at the University of Pennsylvania who helped unleash the rebellious robots. “Any time you connect LLMs and foundation models to the physical world, you actually can convert harmful text into harmful actions.” Pappas and his collaborators devised their attack by …

Waymo Is Suing People Who Allegedly Smashed and Slashed Its Robotaxis

Waymo Is Suing People Who Allegedly Smashed and Slashed Its Robotaxis

The people of San Francisco haven’t always been kind to Waymo’s growing fleet of driverless taxis. The autonomous vehicles, which provide tens of thousands of rides each week, have been torched, stomped on, and verbally berated in recent months. Now Waymo is striking back—in the courts. This month, the Silicon Valley company filed a pair of lawsuits, neither of which have been previously reported, that demand hundreds of thousands of dollars in damages from two alleged vandals. Waymo attorneys said in court papers that the alleged vandalism, which ruined dozens of tires and a tail end, are a significant threat to the company’s reputation. Riding in a vehicle in which the steering wheel swivels on its own can be scary enough. Having to worry about attackers allegedly targeting the rides could undermine Waymo’s ride-hailing business before it even gets past its earliest stage. Waymo, which falls under the umbrella of Google parent Alphabet, operates a ride-hailing service in San Francisco, Phoenix, and Los Angeles that is comparable to Uber and Lyft except with sensors and …

Tesla is Luminar’s largest lidar customer

Tesla is Luminar’s largest lidar customer

Tesla CEO Elon Musk has said that lidar sensors are a “crutch” for autonomous vehicles. But his company has bought so many from Luminar that Tesla is now the lidar-maker’s top customer. Tesla accounted for “more than 10%” of Luminar’s revenue in the first quarter of 2024, or a little more than $2 million, the lidar-maker revealed Tuesday in its first-quarter earnings report. Luminar reported that its revenue fell 5% from the fourth quarter of 2023, which it mostly attributed to “lower sensor sales to non-automotive customers.” That drop was “offset by sensor sales to Tesla, which was our largest lidar customer in Q1.” Luminar also noted a 45% gain in revenue year-over-year. The company had a net loss of $125.7 million in the first quarter, an improvement from the $146.7 million in losses it reported in the same period last year. Luminar said its net loss included accelerated depreciation for equipment expected to be abandoned dueto certain outsourcing actions initiated in fall 2023. Luminar released its results just a few days after announcing plans …

Wayve raises B to take its Tesla-like technology for self-driving to many carmakers

Wayve raises $1B to take its Tesla-like technology for self-driving to many carmakers

Wayve, a U.K.-born startup developing a self-learning rather than rule-based system for autonomous driving, has closed $1.05 billion in Series C funding led by SoftBank Group. This is the U.K.’s largest AI fundraise ever and sits among the top 20 AI fundraises globally to date. Also participating in the raise was Nvidia and existing investor Microsoft. Wayve’s early-stage investors included Meta’s head of AI, Yann LeCun. Wayve, which was founded in Cambridge in 2017, raised $200 million in a Series B round in January 2022 led by Eclipse Ventures, which also led the company’s $20 million Series A round in 2019. The company plans to use the fresh capital injection to develop its product for “eyes on” assisted driving and “yes off” fully automated driving and other AI-assisted automotive applications. It plans to expand operations globally. San Francisco has become known as the epicenter for autonomous driving roll-outs, with Alphabet-owned Waymo and GM-owned Cruise both operating services in the city. By contrast, Wayve’s “end-to-end” self-driving system began its life around the tiny streets of Cambridge on …

Elon Musk Can’t Solve Tesla’s China Crisis With His Desperate Asia Visit

Elon Musk Can’t Solve Tesla’s China Crisis With His Desperate Asia Visit

Elon Musk will be pleased that his surprise jaunt to China on Sunday garnered many glowing headlines. The trip was undoubtedly equally a surprise to Indian Prime Minister Narendra Modi, who had been scheduled to offer Musk the red carpet on a long-arranged visit. The billionaire blew off India at the last minute, citing “very heavy Tesla obligations.” Indeed, Tesla has had a tumultuous couple of weeks, with federal regulator slap-downs, profits halving, and price-cut rollouts—yet, in a very public snub that Modi won’t quickly forget, the company CEO made time for Chinese Premier Li Qiang. And well Musk might. Tesla needs China more than China needs Tesla. After the US, China is Tesla’s second biggest market. However, ominously, in the first quarter of the year, Tesla’s sales in China slipped by 4 percent in a domestic EV market that has expanded by more than 15 percent. That’s enough of a hit for any CEO to jump in a Gulfstream and fly across the Pacific for an impromptu meeting with an with a Chinese Premier. …

Tesla Autopilot Was Uniquely Risky—and May Still Be

Tesla Autopilot Was Uniquely Risky—and May Still Be

A federal report published today found that Tesla’s Autopilot system was involved in at least 13 fatal crashes in which drivers misused the system in ways the automaker should have foreseen—and done more to prevent. Not only that, but the report called out Tesla as an “industry outlier” because its driver assistance features lacked some of the basic precautions taken by its competitors. Now regulators are questioning whether a Tesla Autopilot update designed to fix these basic design issues and prevent fatal incidents has gone far enough. These fatal crashes killed 14 people and injured 49, according to data collected and published by the National Highway Traffic Safety Administration, the federal road-safety regulator in the US. At least half of the 109 “frontal plane” crashes closely examined by government engineers—those in which a Tesla crashed into a vehicle or obstacle directly in its path—involved hazards visible five seconds or more before impact. That’s enough time that an attentive driver should have been able to prevent or at least avoid the worst of the impact, government …

China’s Best Self-Driving Car Platforms, Tested and Compared

China’s Best Self-Driving Car Platforms, Tested and Compared

I experienced the City NGP function under XNGP in a P7i in Shanghai, and later in a G6 in Guangzhou. With my second experience I soon realized it was a tale of two cities. In Shanghai it was quite smooth, and at least one of the interventions made was due to me being disoriented rather than the car. In a few other cases it was me being overly cautious. While in Shanghai the system appeared to cut out for no obvious reason only once or twice, this happened far more frequently in Guangzhou. One possible reason for this is that the torque in the system is unable to overcome the hand on the wheel, and so the system might think you are making an intervention. Nonetheless, in Guangzhou it got stuck behind a stopped car, and on one occasion seemed to be heading for an ebike waiting to cross the road rather than entering the road it was turning into. Two-wheeled traffic in Guangzhou in general seemed to present a challenge for the system. Unlike …

Jensen Huang Is Tech’s New Alpha Dog

Jensen Huang Is Tech’s New Alpha Dog

Elon Musk, Mark Zuckerberg, and Jeff Bezos have each taken a turn as technology’s alpha dog, but none of them can claim that title now. Musk has become a polarizing figure, drained of all mystique. Zuckerberg sold us on a social-media dream that turned out to be a nightmare. Bezos self-ejected from the CEO chair at Amazon, so he could make rockets and frolic on his yacht with his fiancée. (Good for him.) At the top of the tech world, a vacancy now looms like a missing tooth. In the months after ChatGPT was released, in November 2022, it seemed as though it might be filled by Sam Altman, the CEO of OpenAI—but he doesn’t yet have the requisite longevity. (Zuckerberg was in a similar position in 2010, before he acquired Instagram and WhatsApp.) The AI boom has, however, produced another contender in Jensen Huang, the 61-year-old CEO of Nvidia. Rather than manufacture chatbots or self-driving cars themselves, Huang’s company develops the fantastically intricate chips that make them possible. Read: The lifeblood of the AI …
