DeepMind’s table tennis robot
Google’s DeepMind Robotics team recently made headlines with their development of a table tennis robot capable of playing at a “solidly amateur human level.” In their paper titled “Achieving Human Level Competitive Robot Table Tennis,” the researchers describe their robot’s performance against human opponents.
The robot managed to win all matches against beginner players and secured victory in 55% of games against intermediate players. However, it struggled against advanced players, losing every match. Overall, the robot won 45% of the 29 games it played.

How the table tennis robot works
The table tennis robot is built with a clever system that helps it decide which moves to make during a game. Think of it as having two levels of decision-making: the low-level controllers and the high-level controllers. The low-level controllers handle specific skills like forehand topspin or backhand targeting, similar to how a player might practice different shots. Meanwhile, the high-level controller acts like a coach, choosing which skill to use based on the situation in the game and what it knows about its opponent.
One of the coolest things about this robot is its ability to adapt in real time. It keeps track of how well each skill works and adjusts its strategy on the fly. As it plays, it learns more about its opponent’s strengths and weaknesses, allowing it to refine its approach and become a better competitor.
Before hitting the real table, the robot trains in a virtual world. This is where it practices and learns without any risk. Once it’s ready, it transitions smoothly to playing real matches. This process of moving from simulation to reality helps it improve its skills over time, making it more effective with each game.
The robot’s performance is constantly evaluated through matches against human players. Feedback from these games helps it get even better. This advanced system not only makes the robot a tough opponent but also a fun and engaging practice partner for players of all levels.

Challenges for the table tennis robot
Despite its successes, the robot faces significant challenges, particularly in reacting to fastballs. DeepMind attributes these difficulties to system latency, mandatory resets between shots and insufficient data.
To overcome these hurdles, the researchers are exploring advanced control algorithms and hardware optimizations, such as predictive models for ball trajectories and faster communication protocols between sensors and actuators.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?
Beyond table tennis
The implications of this research extend beyond the confines of table tennis. DeepMind highlights the potential of their robot’s policy architecture, simulation use, and real-time strategy adaptation to influence robotics in broader contexts. The ultimate goal is to achieve human-level performance in various real-world tasks, paving the way for robots capable of interacting safely and skillfully with humans.

Kurt’s key takeaways
DeepMind’s table tennis robot demonstrates the potential for machines to engage in complex human activities. While there are still challenges to address, such as improving reaction times and handling diverse ball spins, the progress made so far is promising. As technology advances, we can expect robots to become even more adept at performing a wide range of tasks, making them valuable companions in both recreational and practical settings in our lives.

Formula 1’s new gyro camera adds a Dutch angle to the Dutch Grand Prix
Formula 1 broadcast footage from the Dutch Grand Prix qualifiers at Circuit Zandvoort this weekend that was captured by a gyro camera system mounted above the helmet of the weekend’s race winner, Lando Norris.
The camera, which F1 has been testing since 2022, was conceived with an eye particularly toward accentuating exaggerated angles of banked turns at Zandvoort, but despite using it there last year, F1 wasn’t able to broadcast it, according to AutoSport.
Dino Leone, Formula 1’s head of onboard camera operations, explained in a recent video that the camera allows for on-the-fly adjustments to increase or decrease the gyroscopic effect. Formula 1 used the camera in some 2023 races, such as in Brazil and Japan, and plans to use it more often this year.

AI was responsible for the fake quotes in the Megalopolis trailer
So, all those faked review quotes from the Megalopolis trailer that got pulled last week were apparently AI, after all. Not only that, but the person who was in charge of the materials for the trailer, Eddie Egan, has been removed from the movie’s marketing team.
That’s all according to Deadline, which reported on Friday that the AI-ness of it all was confirmed in an investigation after the fact. Neither Egan nor Megalopolis studio Lionsgate meant to fake the quotes, which had purported to be critical notes from contemporaneous reviews of Megalopolis director Francis Ford Coppola’s past films.
According to some of the trailer’s quotes, critics had called The Godfather a “sloppy, self-indulgent movie,” while Apocalypse Now was “an epic piece of trash.” But as Vulture noted when it first reported on the quotes’ spuriousness, the actual reviews the quotes were attributed to not only didn’t say those things, but often were actually written in praise of the movies.
It’s easy to see how this could have happened. AI’s casual, confident delivery of falsehoods is well documented at this point; even the companies that make AI products end up with factual errors in their own presentations.

The urgent Chrome update you can't ignore and why you need the update now
Google Chrome isn’t having the best year in 2024. The web browser has been hit with a bunch of vulnerabilities, though Google quickly patched them up.
In the latest twist, Microsoft found another vulnerability in Chrome, which Google admitted is being exploited by hackers.
The search giant rolled out an update to fix it just two days after finding out. So, if you haven’t updated your browser yet, you’ll want to do it now.

Google remains tight-lipped about the vulnerability
Google hasn’t revealed how the vulnerability affects users or how hackers are exploiting it. That’s probably because the company doesn’t want to give threat actors any ideas and also wants to give users enough time to update their Chrome browser.
“Until a majority of users are updated with a fix, we will also retain restrictions if the bug exists in a third-party library that other projects similarly depend on but haven’t yet fixed,” the company said.
Tracked as CVE-2024-7971, Google has described it as a type confusion bug in the V8 JavaScript and WebAssembly engine.
“Type confusion in V8 in Google Chrome prior to 128.0.6613.84 allowed a remote attacker to exploit heap corruption via a crafted HTML page,” according to a description of the bug in the NIST National Vulnerability Database (NVD).
In simple terms, this vulnerability allows hackers to take control of your Chrome browser on your desktop by tricking it with a fake HTML page. If successful, they could steal your data or install malicious software, all without your knowledge.
The vulnerability was found and reported by the Microsoft Threat Intelligence Center (MSTIC) and Microsoft Security Response Center (MSRC) Aug. 19.
We contacted Google requesting comment, and a representative confirmed that Google has issued an update to patch this issue.

3 additional ways to protect your privacy
While updating Chrome should fix the vulnerability, below are some security tips you can follow to further bolster your privacy and security.
1. Have strong antivirus software: Hackers often gain access to devices by sending infected emails or documents or tricking you into clicking a link that downloads malware. You can avoid all of this by installing strong antivirus software that will detect any potential threat before it can take over your device or router.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.
2. Recognize urgent requests as potential scams: Always be wary if someone is urgently requesting you to do something like send money, provide personal information or click on a link. Chances are it’s a scam.
3. Use strong and unique passwords: Create strong passwords for your accounts and devices, and avoid using the same password for multiple online accounts. Consider using a password manager to securely store and generate complex passwords. It will help you to create unique and difficult-to-crack passwords that a hacker could never guess. Second, it also keeps track of all your passwords in one place and fills passwords in for you when you’re logging into an account so that you never have to remember them yourself. The fewer passwords you remember, the less likely you will be to reuse them for your accounts. Get more details about my best expert-reviewed Password Managers of 2024 here
