Chinese tech company Xiaomi — perhaps best known in the West for ripping off Apple’s designs — has unveiled a prototype bipedal robot: the slick-looking CyberOne.

The bot was unveiled last week, and, judging from a brief demo, can do little more than walk across a stage. However, the CyberOne does show us the current state of robot development for a non-specialized company like Xiaomi and offers valuable context as to what we might expect from a, uh, rather similar looking bipedal bot: Tesla’s much-hyped Optimus robot, due to be unveiled as a prototype later this year on September 30th.

As per Xiaomi’s official specs, the CyberOne weighs 52kg (114lbs) and stands 177cm tall (that’s 5 foot 8 inches — officially making CyberOne a short king). It has a top speed of 3.6km/h (that’s 2.2mph, just below average walking pace) and comes with a pair of mitten-like hands that can open and close but seem incapable of more dextrous movement.

The bot has some sort of machine vision system for navigation that can do depth-sensing at distances of up to eight meters, and Xiaomi claims it can also “perceive” human emotion, presumably using some sort of AI system to parse facial expressions. (An important side-note here: experts say these sorts of emotion recognition AI are essentially unscientific, and some tech giants like Microsoft have stopped offering them for this reason.)

Here’s an entertaining video of CyberOne walking about and falling over a lot. It’s worth pointing out that we never see CyberOne picking itself up (because it absolutely can’t).

As far as cutting-edge robotics go, then, the CyberOne is an admirably slick package that offers no particularly surprising capabilities. In terms of mobility it’s outclassed by bipedal creations from Boston Dynamics, and in terms of perception and processing its features are not that remarkable. So why build it at all?

Well, over at IEEE Spectrum, robot reporter Evan Ackerman astutely points out that Xiaomi is actually being quite upfront about CyberOne’s purpose. In a press release, the company describes CyberOne as a “symbol of Xiaomi’s dedication to incubate a technological ecosystem” and says work on the bot will “give birth to more application scenarios in other fields” (emphasis mine). In other words: CyberOne is a marketing tool and a platform for broader R&D efforts and Xiaomi is not promising to build a robot butler any time soon.

But, like a butler sounding the dinner bell, though, those words should call attention to the other robot in this analysis: Tesla’s Optimus.

In comparison to Xiaomi, Tesla founder Elon Musk has promised to build a robot butler. When the company’s man in spandex suit humanoid bot was unveiled last year, Musk said the machine would be able to follow complex human commands like “please go to a store and get me the following groceries.” He’s since repeated such claims, recently describing the Tesla Optimus as a “general-purpose humanoid robot” that will “replace people in repetitive, boring, and dangerous tasks.”

As is usual for Tesla’s CEO, Musk conflates timelines and muddies the distinction between possible future tech and current capabilities in order to give listeners’ imagination free rein. But let’s be clear: Tesla is not selling a “general purpose” robot any time soon.

As I wrote last year, promises like this are just far beyond what even cutting-edge tech can do. Robots can perform basic labour, yes, but in constrained and specialized scenarios, like industrial bots in factories and robo vacuum cleaners. When it comes to building a general purpose bot, Xiaomi’s CyberOne provides a much more realistic picture of what to expect.

I’ve said before that I believe Tesla will build and unveil a prototype humanoid bot. Like Xiaomi’s CyberOne, it will be able to walk and talk in prearranged demos, and may display some more advanced hand movement or lifting capabilities (like, for example, Agility Robotics’ Digit bot, which is bipedal and can lift up to 18 kilograms). But it certainly won’t be buying your groceries any time soon. As the CyberOne shows, it’s fun and productive to build a robot for both marketing and research purposes. But I just wish Elon Musk could be as honest as Xiaomi about what to actually expect from this technology.

There’s a surprise in the sky tonight.

Jupiter will be about 367 million miles away from Earth this evening. While that may seem like a long way, it’s the closest it’s been to our home planet since 1963.

During this time, Jupiter will be visible to the naked eye (but binoculars can help). You can check where and when you can get a glimpse of the gas giant from this website.

Missing classic Mario?

One fan, who goes by the name Metroid Mike 64 on Twitter, just built a full-on 2D Mario game inside Super Mario Maker 2 complete with 40 levels and eight worlds.

Looking at the gameplay shared on Twitter is enough to make me want to break out my SNES, or at least buy Super Mario Maker 2 so I can play this epic retro revamp.

The US might still force TikTok into a data security deal with Oracle.

Netflix’s gaming bet gets even bigger.

Even though fewer than one percent of Netflix subscribers have tried its mobile games, Netflix just opened up another studio in Finland after acquiring the Helsinki-based Next Games earlier this year.

The former vice president of Zynga Games, Marko Lastikka, will serve as the studio director. His track record includes working on SimCity BuildIt for EA and FarmVille 3.

Vietnam’s EV aspirant is giving big Potemkin village vibes

Idle equipment, absent workers, deserted villages, an empty swimming pool. VinFast is Vietnam’s answer to Tesla, with the goal of making 1 million EVs in the next 5-6 years to sell to customers US, Canada and Europe. With these lofty goals, the company invited a bunch of social media influencers, as well as some auto journalists, on a “a four-day, multicity extravaganza” that seemed more weird than convincing, according to Bloomberg.

Today, 39 years ago, the world didn’t end.

And it’s thanks to one man: Stanislav Petrov, a USSR military officer who, on September 26th, 1983, took the decision not to launch a retaliatory nuclear attack against the US. Petrov correctly guessed that satellite readings showing inbound nukes were faulty, and so likely saved the world from nuclear war. As journalist Tom Chivers put it on Twitter, “Happy Stanislav Petrov Day to those who celebrate!” Read more about Petrov’s life here.

Deepfakes were made for Disney.

You might have seen the news this weekend that the voice of James Earl Jones is being cloned using AI so his performance as Darth Vader in Star Wars can live on forever.

Reading the story, it struck me how perfect deepfakes are for Disney — a company that profits from original characters, fans' nostalgia, and an uncanny ability to twist copyright law to its liking. And now, with deepfakes, Disney’s most iconic performances will live on forever, ensuring the magic never dies.

Teen hacking suspect linked to GTA 6 leak and Uber security breach charged in London.

City of London police tweeted Saturday that the teenager arrested on suspicion of hacking has been charged with “two counts of breach of bail conditions and two counts of computer misuse.”

They haven’t confirmed any connection with the GTA 6 leak or Uber hack, but the details line up with those incidents, as well as a suspect arrested this spring for the Lapsus$ breaches.
