China’s robot industry is heating up as companies prepare to conquer the final frontier in humanoid robot development. The Tesla Optimus bot team is working to do the same on the other side of the world. Which humanoid robot developer will come out on top?

Dexterous hands are said to be the last frontier in humanoid robot development. Robotic hands have become essential to humanoid robots taking on human workloads. As such, companies are increasingly focused on developing the most dexterous robotic hands.

Linkerbot Technology recently debuted its Linker hand for humanoid robots. The Chinese company claims its Linker Hand has the highest dexterity on the market.

“Our Linker Hand research version has the world’s highest 42 degrees of freedom (DOF), surpassing the 26 of the world’s leading product, Shadow Hand. Each finger could independently have up to 7 DOF, which means it has surpassed human fingers. It is also equipped with an advanced multi-sensor system, including cameras and electronic skin,” said Gao Gang, Deputy General Manager of Linkerbot Technology at the 27th China Beijing International High-tech Expo (CHITEC).

Last year, Elon Musk shared that Tesla’s new Optimus hand would have 22 degrees of freedom. In May 2024, Tesla released a new video of Optimus in the company’s facilities. The Tesla video featured Optimus performing several tasks in a factory, including those requiring precision. In a comment about the Optimus video, NVIDIA Sr. Research Manager & Lead of Embodied AI (GEAR Lab), Jim Fan, noted that Optimus’ hands are among the best in the industry.

It would be interesting to see Tesla’s improvements on the Optimus hand. The video from last year already showed Optimus handling delicate tasks, which would improve its functionality in factories. Linkbot expects to showcase the capabilities of its own dexterous robotic hand in the future as well.

“In years to come, Linkerbot aims to deploy 1 million humanoid robots equipped with dexterous hands in the real world to collect data. Including, but not limited to, playing with a Rubik’s Cube. Putting on makeup is included in our fine motor standardized test scenarios,” noted Gao.

Linkerbot isn’t the only Chinese company developing humanoid robots. A few companies in China are creating robots that can work in factories.

Tesla Optimus is expected to perform menial, monotonous, repetitive tasks that could harm humans. PaXini Tech, another Chinese company, is also planning to release a humanoid robot to perform work tasks. Similar to Linkbot, PaXini Tech emphasized its humanoid robot’s dexterous hands and its capabilities.

“Our DexH13 GEN2 is the first four-finger bionic dexterous hand in the domestic market that integrates multi-dimensional tactile + AI visual dual-modal capabilities, which can perfectly simulate various complex movements of human hands such as welding, grasping, rotating, and pinching,” said Dr. Xu Jincheng, founder and CEO of PaXini Tech, a leading haptic technology and humanoid robotics company in China.

Tesla watchers spot mysterious castings at Fremont Factory

The castings seem to be quite new, as they do not seem to match any of the castings that are currently being used for the Model Y.

A recent flyover of the Fremont Factory has triggered speculations about Tesla’s ongoing initiatives that are yet to be unveiled publicly. This was hinted at by the sighting of some apparent vehicle castings around the factory that have never really been observed before.

A Fremont Factory flyover

In a recent update, drone operator Met God in Wilderness, who has been chronicling the progress and developments of the Fremont Factory for years, shared some footage from his August 14, 2025 flyover. Based on the video, the Fremont Factory seemed very much alive. Vehicles were being pumped out of the factory, and a rather interestingly covered car could be seen going around the test track.

What is quite fascinating about the footage from the Fremont Factory is the fact that the vehicles that were moving from the production line to the outbound logistics lot are not driven manually anymore. As per Tesla in previous updates, vehicles produced at the Fremont Factory navigate to the outbound logistics lot on their own using Unsupervised FSD

Mysterious castings

Perhaps most interestingly, the drone operator also managed to capture some footage of some castings that were being gathered just outside one of the facility’s sprung structures. These castings seem to be quite new, as they do not seem to match any of the castings that are currently being used for the Model Y. This has brought speculations suggesting that the new components, which seem smaller than standard Model Y megacasts, may be for a different, perhaps more compact, vehicle. 

As per Tesla in its second quarter earnings call, the company actually started the initial production of more affordable models sometime in June. These vehicles, as per Elon Musk, will be made available for consumers in the fourth quarter. “Given that we started in North America and that our goal is to maximize production with higher rates by the end of Q3, we’re going to keep pushing hard on our current models to avoid complexity… We’ll be running with the more affordable models available for everyone in Q4,” Musk said.

Shareholder group urges Nasdaq probe into Elon Musk’s Tesla 2025 CEO Interim Award

The SOC Investment Group represents pension funds tied to more than two million union members, many of whom hold shares in TSLA.

An investment group is urging Nasdaq to investigate Tesla (NASDAQ:TSLA) over its recent $29 billion equity award for CEO Elon Musk. 

The SOC Investment Group, which represents pension funds tied to more than two million union members—many of whom hold shares in TSLA—sent a letter to the exchange citing “serious concerns” that the package sidestepped shareholder approval and violated compensation rules.

Concerns over Tesla’s 2025 CEO Interim Award

In its August 19 letter to Nasdaq enforcement chief Erik Wittman, SOC alleged that Tesla’s board improperly granted Musk a “2025 CEO Interim Award” under the company’s 2019 Equity Incentive Plan. That plan, the group noted, explicitly excluded Musk when it was approved by shareholders. SOC argued that the new equity grant effectively expanded the plan to cover Musk, a material change that should have required a shareholder vote under Nasdaq rules.

The $29 billion package was designed to replace Musk’s overturned $56 billion award from 2018, which the Delaware Chancery Court struck down, prompting Tesla to file an appeal to the Delaware Supreme Court. The interim award contains restrictions: Musk must remain in a leadership role until August 2027, and vested shares cannot be sold until 2030, as per a Yahoo Finance report.

Even so, critics such as SOC have argued that the plan does not have of performance targets, calling it a “fog-the-mirror” award. This means that “If you’re around and have enough breath left in you to fog the mirror, you get them,” stated Brian Dunn, the director of the Institute for Comprehension Studies at Cornell University.

SOC’s Tesla concerns beyond Elon Musk

SOC’s concerns extend beyond the mechanics of Musk’s pay. The group has long questioned the independence of Tesla’s board, opposing the reelection of directors such as Kimbal Musk and James Murdoch. It has also urged regulators to review Tesla’s governance practices, including past proposals to shrink the board. 

SOC has also joined initiatives calling for Tesla to adopt comprehensive labor rights policies, including noninterference with worker organizing and compliance with global labor standards. The investment group has also been involved in webinars and resolutions highlighting the risks related to Tesla’s approach to unions, as well as labor issues across several countries.

Tesla has not yet publicly responded to SOC’s latest letter, nor to requests for comment.

The SOC’s letter can be viewed below.

Tesla Model Y L has two distinct features for luxurious comfort

This is not to say the other interior additions are not factors in the Model Y becoming a more luxurious and premium vehicle, but the two mentioned in this article are particularly pertinent in that conversation.

Tesla’s new Model Y L has two distinct features that are geared toward giving occupants a taste of luxury with guaranteed comfort.

These two features should definitely be part of the company’s future lineup, and they could prove to be massive upgrades to the Model Y’s interior, which is certainly premium but is missing some things that truly tailor to a “luxury” feel of an automobile.

This is not to say the other interior additions are not factors in the Model Y becoming a more luxurious and premium vehicle, but the two mentioned in this article are particularly pertinent in that conversation.

Tesla Model Y L might not come to the U.S., and it’s a missed opportunity

Power-Adjustable Thigh Supports

In the front seats of the Model Y L, there are power-adjustable thigh supports that will enable some additional comfort on the legs:

Most might think that these thigh supports are simply a feature that makes the ride more comfortable, which is true. However, they have benefits for the ride and after you exit the car.

Providing proper lift on the legs and thighs can be beneficial for people with back problems or posture issues. The lower back takes an increased amount of stress during long car rides, especially as the legs are fixed in the chosen seating position.

Tesla Model Y L officially launched: price, features, and more

Adding some support to the thighs can help reduce pressure on the lower back and hips, and distribute weight more evenly, taking stress off pressure points.

It can also contribute to better spinal alignment. They also have safety benefits, as some riders could have an improved seatbelt position thanks to the thighs being in this position.

Second-Row Mechanical Armrest

Tesla also added mechanical, one-touch armrests to the Model Y L’s second row, a nice and premium touch for the riders in the middle of the vehicle:

Add the additional space the Model Y L provides to riders, and it already gets more comfortable. However, the addition of the mechanical armrests gives a good option of comfort for those who are seated in the second row.

They can also be retracted with the touch of a button, allowing for those in the third row to exit the vehicle easily.

One con to the mechanical portion of these armrests is that it is another moving part, and, of course, that puts it at risk of having issues.

However, it is certainly more premium than a manual armrest, and the flashy carbuyers will appreciate this small but mighty addition.
