Killer hacked robots, Optimus in production, NVIDIA's platform wins, micro-factories staffed by robots, and more!
Tesla starts Optimus production ... but how many?
Tesla has started early production of Optimus on its high-volume manufacturing line in Fremont, California. Elon Musk announced the milestone during Tesla's Q3 earnings call alongside a note that profits fell 43%.
The production ambition is staggering: 20,000 robots per week, more than a million per year. Musk says that rate is at least a year away.
But ... that's WAY MORE than the world is ready to buy right now.
According to the International Federation of Robotics, the entire world bought about 7,000 full-size humanoid robots in 2025. Tesla is talking about making almost three times that many every single week.
And there are reasons to be skeptical about how quickly it can get there.
Tesla just reduced its planned 2026 capital expenditures from more than $25 billion to approximately $20 billion. It also spent significantly less in Q3 than analysts expected. We don't know how much of that reduction affects Optimus, but it's an interesting contrast with the enormous production ambitions.
Meanwhile, Tesla hasn't disclosed how many robots it's actually producing. Musk acknowledged that the hands, safety, reliability, durability, and AI still need work. The robot's design is still evolving, and Tesla's next-generation AI5 chip isn't expected to be integrated until around April 2027.
Deliveries to outside customers? Potentially the end of 2027.
Data and AI is also still a challenge. Musk described the training challenge as being like raising a toddler. Tesla is developing an Optimus Academy to teach robots how to perform useful work.
So yes, Optimus is coming off a real production line, sure. But there's a massive difference between starting production, having capacity for a million robots, and actually making a million useful robots.
Right now, Tesla is doing the first one.
NVIDIA wants to own the robot platform
At GTC Berlin, NVIDIA made its robotics ambitions pretty clear. Jensen Huang says the ChatGPT moment for robotics is approaching.
- Isaac Lab 3.0 is generally available, validated across more than 200 robot configurations.
- GR00T N1.7 is in early access, with inference latency dropping from 500 milliseconds to just 60 on supported hardware.
- GR00T N2 is coming by the end of 2026, with NVIDIA claiming double the task success rate of N1.5.
And hardware companies are lining up.
Agile Robotics unveiled ONE SN, a commercial humanoid built on NVIDIA's full software stack. Agility Robotics is standardizing Digit 5 on IGX Thor, and NVIDIA's Halos safety framework added five new hardware partners.
NVIDIA is building the compute, simulation, foundation models, and safety infrastructure, while other companies build the robots. It's the same platform playbook NVIDIA used to dominate AI data centers.
Now it wants to do it again in physical AI to ... you guessed it ... sell more chips!
1 word turns a robot violent
Researchers at Binghamton University demonstrated a disturbing attack: they gave a robot a knife and a normal instruction to cut an apple. But adding just 1 word triggered malicious behavior, causing the robot to attack a model human hand instead.
The attack, called MuTRAP, succeeded between 97 and 100 percent of the time across seven AI models.
The vulnerability isn't a conventional prompt injection. It's hidden inside a poisoned task-specific adapter ... exactly the kind of component robot developers might obtain from third parties.
The robot behaves normally until it encounters the trigger, and standard safety benchmarks didn't catch it. The researchers have proposed a defense, called PROTEA, but its effectiveness against the full demonstrated attack still needs validation.
The takeaway: robot security isn't just about stopping hackers from accessing a robot. It's also about trusting the software and AI components that make the robot work.
And when robots are in our homes, this is critically important.
Unitree's CEO warns investors
Unitree's stock has been on an extraordinary ride.
The company went public in August at a valuation around $9 billion, briefly reached $66 billion, then plunged more than 60 percent. Now it's surging again, triggering a formal abnormal-trading warning.
The price-to-earnings ratio: 388 times earnings, or almost ten times the equipment manufacturing sector average. CEO Wang Xingxing is warning about early-stage commercialization, unresolved technical challenges, and potential valuation regression.
Tiny humanoid factories could change manufacturing
A Swedish startup called 120ft has emerged from stealth with just €576,000 in angel funding.
That's pocket change in humanoid robotics, but the idea is fascinating.
Instead of massive factories producing thousands of identical products overseas, 120ft wants to build tiny, local microfactories powered by humanoid robots. Each factory consists of three 40-foot shipping containers — 120 feet in total — handling preparation, assembly, inspection, and packing.
Brands provide their product designs. The robots assemble small batches locally. Customers pay per finished product, not for the robots. The company has already demonstrated robots assembling a lamp, and says it has reduced the time needed to teach an assembly skill from seven weeks to seven hours.
Its goal for 2027? Seven minutes.
Imagine ordering a customized product that's assembled locally, on demand, by humanoids. No enormous factory, no shipping container crossing an ocean, no massive inventory commitment. That's the vision. As usual, commercial-scale operations still have to be proven.
Meet Voxel, the humanoid with personality
And from New York City, Tuesday Labs has introduced Voxel Series-1, a household humanoid that looks like it escaped from a Pixar movie. Its bright, colorful design, square eyes, and deliberately expressive personality are a pretty big departure from the industrial humanoids we're used to seeing.
But this isn't just an exercise in making robots cute.
Voxel is designed to tidy your home, find misplaced objects, fetch things, and even care for your plants. It has seven-degree-of-freedom arms, articulated wrists, grippers, stereo vision, and unusual Z-shaped legs. Tuesday Labs is also working with illustrators, animators, and character designers to give the robot a personality people actually want to live with.
Of course, the company still has to prove those household capabilities work reliably in the real world.
But there's an interesting design philosophy here, and if humanoids are eventually going to live in our homes, maybe they shouldn't look like factory equipment.
Maybe they should look like someone (ok, something) we'd actually enjoy having around.
Number of the day: 348
The number of the day is 348.
That's how many miles Figure AI's Figure 03 humanoid walked on a treadmill in nine consecutive days. It's about 1.2 million steps, roughly the distance from San Francisco to Los Angeles.
The robot was externally powered, so this wasn't a battery endurance test. It was about mechanical durability: what happens to joints, actuators, bearings, and moving components when you subject them to relentless repetitive motion?
And the end result is pretty impressive. It's more steps over more days than I can do, that's for sure.
