Tesla has revealed some of its humanoid robot technology through filings for several new patents related to its Optimus robot program.

A few months ago, Tesla unveiled “Optimus Gen 2”, a new generation of its humanoid robot that should be able to take over repetitive tasks from humans.

The new prototype showed a lot of improvements compared to previously underwhelming versions of the robot, and it gave some credibility to the project.

One of the main changes with the Optimus Gen 2 is the fact that Tesla is now using all its own inhouse-designed custom actuators to power the robot’s limbs.

Now, Tesla has filed several patents related to the technology behind its humanoird robot.

In the first patent, Tesla describes its ‘actuator and actuator design methodology’:

A system or methodology of controlling movement of a robot (600) using actuators, the system can include one or more first type of actuators (1002) positioned at torso, shoulder, and hip locations of the robot; one or more second type of actuators (1004) positioned at wrist locations of the robot; one or more third type of actuators (1006) positioned at the wrist locations of the robot; one or more fourth type of actuators (1008) positioned at elbow and ankle locations of the robot; one or more fifth type of actuators (1010) positioned at the torso location and the hip locations of the robot; and one or more sixth type of actuators (1012) positioned at knee locations and the hip locations of the robot.

Here are some of the drawings from the patent application:

Interestingly, the first gen Optimus is featured in those drawings for the first patent application.

The other patent applications feature images of the new Optimus.

The next patent is called ‘Sytems and methods for a robot knee joint assembly’ and as the name suggest, it is specifically about the bot’s knee.

Tesla described the technology in its patent application:

Disclosed herein is a knee joint assembly including a first link member having a first end mechanically coupled to an upper leg of a robot and configured to rotate around a first pivot relative to the upper leg, and a second link member having a first end mechanically coupled to a lower leg of the robot. The lower leg can be mechanically coupled to the upper leg and configured to rotate around a second pivot relative to the upper leg. A linear actuator device can be mechanically coupled to a second end of the first link member and a second end of the second link member, and when actuated can cause the first link member to rotate around the first pivot relative to the upper leg of the robot and cause the leg to rotate around the second pivot relative to the upper leg.

Here are some of the drawings from the patent application:

The last patent application that we found is particularly interesting as it relates specifically to the Tesla Optimus hands.

The patent application is called ‘Underactuated hand with cable-driven fingers’.

Tesla wrote in the patent application:

A robotic hand system can comprise a palm region and one or more fingers, each finger comprising an actuator device; a proximal member having a first end mechanically coupled to the palm region robot and configured to rotate around a first pivot relative to the palm region; a distal member having a first end mechanically coupled to a second end of the proximal member and configured to rotate around a second pivot relative to the proximal member; and a cable having a first portion coupled to the actuator and a second portion extending along the proximal member and the distal member, the second portion separated away from the first pivot and the second pivot and having an end with a higher dimension than a diameter of the cable, the end with higher dimension structured to engage the distal member when the cable is pulled by the actuator.

Here are some of the drawings from the patent application:

In the latest sneak peek at the latest robot prototypes that Tesla showed, we could see much improved hand dexterity.

There’s no clear timeline for Tesla to bring the robot to production, but Tesla CEO Elon Musk said in 2022 that it could go into production as soon as 2023 – though that didn’t happen.

Musk recently said that the robot would cost about half of a car.

Tesla can’t sell its cars anymore so it is renting them now

Tesla can’t sell its cars anymore so it is renting them now

Tesla is launching a new car rental program out of its stores in the US, as sales are crashing due to the end of the federal tax credit.

It’s available at select stores in the US right now.

Tesla’s demand in the US, like that of most other electric vehicles, has crashed after the federal tax credit for electric cars ended last quarter, pulling forward a lot of demand.

With inventories piling up at stores and dealers across the country, Tesla has found a new way to use its inventory: it is now renting (not leasing) its vehicles from its stores.

The rental duration is a minimum of three and a maximum of seven days, starting at $60 per day and increasing depending on the model.

Tesla appears to be using this to show potential buyers how convenient it is to own a Tesla vehicle, since it also includes Supercharging and Full Self-Driving (Supervised) for free with every rental.

If a rental customer decides to order a vehicle within a week of having rented one, Tesla gives them a $250 credit toward the purchase:

Order your own Tesla within seven days of your rental to get up to a $250 credit toward your purchase.

The program is starting with a couple of locations in Southern California, but it is expected to expand before the end of the year.

Car rental giant Hertz has previously bought a large fleet of Tesla vehicles in an effort to electrify its rental fleet.

However, Hertz has been divesting from Tesla vehicles and selling them over the last 2 years, as declining resale values crushed its fleet economics amid Tesla slashing prices due to declining demand over the last 3 years.

Electrek’s Take

It’s rough out there for people selling electric vehicles in the US right now. The lack of policy consistency is resulting in inconsistent demand and discouraging automakers from pushing electric cars, as they do in Europe and Asia.

It’s particularly challenging for automakers like Tesla, Rivian, and Lucid, which sell only electric vehicles, because most people who planned to buy an electric vehicle in 2025 have already bought one in Q3 or earlier.

This rental service is not a bad idea, though, but it’s obviously far from a solution to the demand problem in the US.

It’s wild to think that Tesla’s own CEO is largely responsible for creating this situation by backing Trump in the last elections.

NIU unveils bold new urban and off-road (but street legal!) electric motorbikes

NIU unveils bold new urban and off-road (but street legal!) electric motorbikes

NIU is back at EICMA 2025 (the Milan Motorcycle Show) with a fresh lineup of electric two-wheelers that push the boundaries of performance, design, and smart connectivity. The Chinese electric mobility giant, already known for selling over 5 million electric scooters and motorcycles across over 50 countries, used the Milan show to unveil its 2026 product range – and it’s clear NIU is looking to hang on to that leader status.

For those unfamiliar, NIU launched its first electric scooter way back in 2015 and quickly rose to prominence with sleek, connected vehicles that combined urban practicality with stylish design. There are a lot of electric scooters out there now, but NIU has consistently been known for high-tech and slick-looking models.

Now, a decade later, NIU’s lineup has matured into a globally recognized suite of smart mopeds, e-bikes, scooters, and electric motorcycles. And at this year’s EICMA, the company made it clear that it’s ready to dominate even more niches.

A smarter NQiX Series

The NQiX Series has already gained traction in Europe’s L1e and L3e vehicle categories, but for 2026, it’s getting even better. All models in the series will be updated with improved motor and battery efficiency for longer range and better consistency. Most notably, NIU is adding onboard navigation powered by Google Maps – a major step toward true “smart” scooters.

The biggest news, though, is the introduction of the NQiX 1000. Packing 15.5 kW of peak power and topping out at 125 km/h (78 mph), this model is aimed at commuters who want speed, range, and flexibility. With three removable 72V 28Ah batteries and over 100 km of range, it looks set to be a practical yet powerful urban workhorse. The NQiX 1000 will launch in Q3 2026 with a starting price of €6,499.

My first NIU scooter ever was an NQiGT that I got back in 2020, and it helped me fall in love with the brand. The NQiX series has extended what made the original so impressive, and the NQiX 1000 will push that model line into brand new territory, both for technology and for performance.

FQiX brings a fresh face to urban riding

NIU also introduced a completely new design platform called the FQiX Series, targeted at city dwellers who want tech-forward transportation with a bit of flair. Think sleek body lines, distinctive lighting, and a minimalist aesthetic – paired with smart features like a 5-inch TFT display, rear radar, and Bluetooth/NFC/keyless unlocking.

The FQiX 150 (L1e) and FQiX 300 (L3e) offer two tiers of performance but share the same connected tech ecosystem, powered by NIU’s new “Link Crown” interface. These will also arrive by Q3 2026, starting at just €2,399 – making them a compelling choice for first-time e-scooter riders.

This one definitely feels like NIU’s targetted attempt to bring on younger, more budget conscious riders while still giving them access to the technology that separates the brands’ scooters from much of the competition.

XQi goes off-road (and on-road, too)

NIU has been teasing off-road ambitions for years, but the new XQi 300, XQi 400, and XQi 500 take those ambitions up several notches. They follow on the heels of the successful launch of the NIU XQi3, which, for a lack of a better way to describe it, is NIU’s Sur Ron competitor. I had the chance to test it out recently on a trip to tour NIU’s factory. But unlike Sur Rons, Talarias, and most other light electric dirt bikes in this category, NIU made the XQi3 street-legal from the start, meaning riders could register it like a motorcycle and also ride on trails.

Now the XQi3 has been revamped into the XQi 300, keeping much of what made it a success untouched, but adding highly requested features like on-board charging so the battery doesn’t need to be unplugged to recharge. The XQi 400 and XQi 500 add even more power and performance, competing more with the Sur Ron Storm Bee. The XQi 500 Street, in particular, is likely to prove quite popular as a street-legal electric dirt bike with a massive 28.8 kW peak output and a top speed of 110 km/h (68 mph), all in a fairly lightweight 92 kg (203 lb) chassis.

Concept 06 maxi-scooter

NIU also showed off a concept for a potentially upcoming maxi-scooter, and it sounds like they actually want to produce it. This likely isn’t just a crazy concept that will never see the road, but rather a roadmap to what could be NIU’s biggest scooter yet.

The company is projecting impressive performance, including a 20 kW motor, speeds of up to 155 km/h (96 MPH), plus fancy features like a tray table so you can get some laptop work done while you’re charging up.

Electrek’s Take

NIU continues to impress me with its mix of smart tech, eye-catching design, and impressive performance. The addition of Google Maps integration and radar safety features is a clear step forward that I’m excited to see implemented. And with models like the XQi 1000, NIU is branching into serious performance territory. And the new off-road bikes (with street-legal status to ride on the road too!) take what was already a great design and make it even more powerful – and convenient to use.

While some of the subscription models might turn off some users, the base functionality of these vehicles seems generous enough to keep most people happy. And all of that tech on top is what helps separate NIU. If the pricing holds and the specs deliver, I think NIU’s 2026 lineup could shake up both urban and off-road electric mobility in a big way.

Tesla’s head of Cybertruck program is leaving the company

Tesla's head of Cybertruck program is leaving the company

Tesla’s head of the Cybertruck program, Siddhant Awasthi, announced that he is leaving after more than 8 years at the company.

Awasthi is a good example of Tesla’s transition into fostering inside leadership rather than outside hiring.

For better or worse, over the last 5 years, Tesla has virtually had no significant outside hires into high-level leadership roles. It almost exclusively promotes from within.

Awasthi worked on a hyperloop school program, interned at Tesla, and joined the company straight out of school in 2018. Within 2 years, he became an engineering manager. Within 3 years, he was a senior technical program manager in charge of the Cybertruck’s 48-volt architecture.

To say that this is unusual at a major company would be an understatement.

By late 2022, ahead of Tesla’s planned start of Cybertruck production, he was made head of the electric truck program.

He was in charge of the production ramp and future improvements to the electric pickup truck, which has since become a commercial flop. Tesla is having trouble selling 25,000 Cybertrucks per year, despite planning for an annual production capacity of 250,000 trucks.

Today, the young engineer announced on X:

I recently made one of the hardest decisions of my life to leave Tesla after an incredible run.

He tried to “sum up” his career at Tesla in a paragraph:

It’s tough to sum up eight years in just a few lines, but what a thrilling journey it’s been: ramping up Model 3, working on Giga Shanghai, developing new electronics and wireless architectures, and delivering the once-in-a-lifetime Cybertruck—all before hitting 30. The icing on the cake was getting to dive back into Model 3 work toward the end.

In addition to his duties as Cybertruck program manager, Awasthi was also made in charge of the Model 3 program last summer.

Tesla has recently completely revamped its vehicle program organization following a wave of layoffs last year and many subsequent departures amid a talent exodus at the company.

Electrek’s Take

While I’m using Awasthi as an example of Tesla prioritizing internal promotions rather than attracting outside talent, I’m not blaming the failures of the Cybertruck program on him. The blame should always be placed at the very top.

The program failed because someone at Tesla —likely Elon —was way too optimistic about what it could accomplish, and ultimately, what Tesla unveiled in 2019 had very little to do with what it brought to production in 2023.

It had less range, fewer cool features, and all for a way higher price.

But it’s also far from an endorsement of Tesla’s organizational approach, far from it.
