Tesla Semi’s vast array of Autopilot cameras and sensors for convoy mode spotted
When CEO Elon Musk unveiled the Tesla Semi to the world, one of the main messages in his presentation was that the all-electric semi-truck is significantly cheaper to own than a traditional diesel truck. With a starting price of $150,000 for the base truck, and $180,000 for the long range 500-mile variant, the Tesla Semi is priced considerably lower than what many industry experts expected.
“We really thought about this a lot. If you take everything into account: take the lease cost, take the insurance cost, maintenance, all of the factors – the fully accounted for true cost of trucking – a diesel truck will be 20% more expensive than a Tesla Semi per mile.” said Musk.
The Tesla Semi is able to achieve high efficiency through the use of four electric motors – the same volume production motors used in the company’s consumer mass market Model 3 sedan – that operate independently to control torque at each wheel. The drivetrain’s design not only allows for blistering acceleration, by truck standards, but also adds an element of safety. “The truck will automatically stop jackknifing because it has independent motors on each wheel and it will dynamically adjust the torque on each wheel so that jackknifing is impossible. Your worse nightmare is gone with this truck.”
However, combined with the truck’s ability to leverage convoy technology wherein a fleet of Tesla semi-trucks semi-autonomously draft in close proximity to one another thereby reducing energy usage from wind resistance, Tesla Semi’s true cost of ownership becomes even more favorable than a diesel truck.
“The convoy technology, the tracking technology, this is something that we are confident we can today do ten times safer than a human driver.” said Musk at the Tesla Semi unveiling event. “I want to be clear, this is something we can do now.”
According to Musk, a diesel truck becomes twice as expensive as a Tesla all-electric truck that’s operating in convoy mode.
Similar to Tesla’s Autopilot-enabled Model S and Model X consumer vehicles, the Tesla Semi is able to use a suite of cameras and sensors to paint a digital picture of its surroundings. Every truck is equipped with Enhanced Autopilot that will allow the vehicle to semi-autonomously stay in lane, automatically brake in emergency situations and warn of forward collisions.

“Even if you’re in an emergency, the truck will stay in lane, and gradually come to a halt, and put on the emergencies. If it doesn’t hear a response from you, it will actually call emergency services and get an ambulance. It’s going to take care of you; it’s going to take care of other cars; it’s going to take care of other pedestrians. This is a massive increase in safety.” said Musk.
On the outside, the sleek Tesla Semi doesn’t appear to have any protruding hardware beyond a “wing” that’s present on either side of the truck. Upon closer investigation by KmanAuto who attended the event and gave us a first look at the Tesla Semi’s gearbox, there’s a vast array of cameras and possibly a LiDAR mounted within the truck’s wings.

Because the Tesla Semi doesn’t have any side mirrors, video from these cameras likely provide the driver with a birds eye view of both sides of the truck as seen from the interior touchscreen displays. Kman also discovered a row of cameras mounted below and above the massive windshield, and even more cameras discreetly mounted within Tesla Semi’s headlight assembly.
Though Musk did not talk about the integration of Full Self-Driving capabilities in the Tesla Semi, Kman notes that it could be possible if Tesla one day offers its own tractor trailers with sensors. “I think Tesla will offer its own tractor trailers. These trailers will be outfitted with their own suite of sensors to enhance the vehicle’s abilities further.” Kman tells Teslarati.
We’ve embedded Kman’s video that captures the various locations of Tesla Semi’s sensor suite. We count at least 12 cameras. How many can you spot?

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…

Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
