Elon Musk started Tesla's AI Day 2022 by saying, "I want to set some expectations with respect to our Optimus Robot," just before the doors opened behind him. A robot walked out, waved at the audience, and did a little dance. Admittedly a humble beginning, he explained, "the Robot can actually do a lot more than what we just showed you. We just didn't want it to fall on its face." Musk's vision for the Tesla Robot, "Optimus is going to be incredible in five years, ten years mind-blowing." The CEO said other technologies that have changed the world have plateaued; the Robot is just starting.

Tesla's CEO envisions Optimus eventually being like Commander Data, the android from Star Trek the Next Generation, except it "would be programmed to be less robot-like and more friendly." Undoubtedly there is a long way to go to achieve what Doctor Noonien Soong created in Star Trek TNG. What was demonstrated onstage wasn't at that level, but several videos throughout the presentation highlighted what the Robot is capable of at its very early stage in development. The audience watched the Robot pick up boxes, deliver packages, water plants and work at a station at the Tesla factory in Fremont.

Development over 8 Months

The first Robot to take the stage at AI Day was not Optimus, but Bumble C, another acknowledgement to The Transformers, as Bumble Bee played a significant role in that franchise. However, Bumble C is far less advanced than Optimus, who did appear later but was on a cart.

Several Tesla engineers took turns on the microphone describing some of the most complex elements of the project that was first announced one year ago. Perhaps the best description of the project was the company moving from building a robot on wheels to a robot on legs. However, that may be oversimplifying. For example, the car has two motors, and the Robot has 28 actuators.

Overall Design and Battery Life

Tesla's brightest demonstrated how the production has come to life over the past eight months. It seems this group of computer masterminds had to become anatomist experts as Tesla took hints from the human body to create a humanoid robot. That is an essential factor in creating Optimus. Everything people interact with is made usable by a human, with two legs, two arms, ten fingers etc. If the Robot differed from what the world is already designed for, everything would have to change. However, recreating the human body and its countless movements would take far too long, so Tesla has stripped it down to less than 30 core movements, not including the hand.

Like the human torso contains the heart, the Robot's chest holds the battery. It's projected that a single charge would provide enough for a full day's work with a 2.3-kilowatt-hour battery. All the battery electronics are integrated into a single printed circuit board within the pack. That technology keeps charge management and power distribution all in one place. Tesla used lessons learned from vehicle and energy production to create the battery allowing for streamlined manufacturing and simple and effective cooling methods.

Autopilot Technology

Tesla showed what the Robot sees, and it looked very familiar. That's because the neural networks are pulling directly from Autopilot. Training data had to be collected to show indoor settings and other products not used with the car. Engineers have trained neural networks to identify high-frequency features and key points within the Robot's camera streams, such as a charging station. Tesla has also been using the Autopilot simulator but has integrated it for use with the Robot programming.

The torso also contains the centralized computer that Tesla says will do everything a human brain does, such as processing vision data, making split-second decisions based on multi-sensory inputs and supporting communications. In addition, the Robot is equipped with wireless connectivity and audio support. Yes, the Robot is going to have conversations, "we really want to have fun, be utilitarian and also be a friend and hang out with you," said Musk.

Motors Mimic Joints

The 28 actuators throughout the Robot's frame are placed where many joints are in the human body. Just one of those actuators was shown lifting a half-tonne nine-foot concert grand piano. There have been thousands of test models run to show how each motor works with the other and how to effectively operate the most relevant actuators for a task. Even the act of walking takes several calculations that the Robot must make in real-time, not only to perform but also appear natural. The robots will be programmed with a locomotion code; the desired path goes to the locomotion planner, which uses trajectories to state estimations, very similar to the human vestibular system.

Human hands can move 300 degrees per second and have tens of thousands of tactile sensors. Hands can manipulate anything in our daily lives, from bulky, heavy items to something delicate. Now Tesla is recreating that with Optimus. Six actuators and 11 degrees of freedom are incorporated into the robot hand. It has an in-hand controller that drives the fingers and receives sensory feedback. The fingers have metallic tendons to allow for flexibility and strength. The hands are being created to allow for a precision grip of small parts and tools.

Responsible Robot Safety

Musk wanted to start AI day with the epic opening scene from Terminator when a robot crushed a skull. He has heard the fears and people warning, "don't go down the terminator path," but the CEO said safety is a top priority. There are safeguards in place, including designs for a localized control ROM that would not be connected to the internet that can turn the Robot off. He sees this as a stop button or remote control.

Optimus Price

Musk said the development of Optimus may broaden Tesla's mission statement to include "making the future awesome." He believes the potential is not recognized by most, and it "really boggles the mind." Musk said, "this means a future of abundance. There is no poverty. You can have whatever you want in terms of products and services. It really is a fundamental transformation of civilization as we know it." All of this at a price predicted to be less than $20,000 USD.

Tesla Updates Service Mode and Service Mode+ With Software Update 2025.2

Tesla recently released software update 2025.2 with several new features, including Hands-Free Frunk and Trunk support for Android, a chime for rear cross-traffic alerts, and third-party charging preconditioning.

However, there are also several new features added to Tesla’s Service Mode and Service Mode+.

Recently, Tesla also added other improvements to Service Mode, including an Interactive Wiring Diagram for the Cybertruck, as well as a new speakers panel and audio test, ambient lighting features and more.

Service Mode Updates

Service Mode allows anyone to access service-related features that help troubleshoot vehicle issues. It’s available for free to all Tesla owners, but caution should be exercised when making any changes. More information about how to access Service Mode is available in our Service Mode guide.

In update 2025.2, Tesla improved two existing Service Mode panels:

Brake Burnishing - Brake burnishing helps condition new brakes and rotors. Tesla states: “The Brake Burnish procedure parameters have been updated to reduce the need for coming to almost a complete stop during each cycle.

This change is available for all vehicles.

Charge Port Calibration - Users can now run a charge port calibration, which can help to either get the charge port to fully close or fully open if you’re having issues or if you’ve refitted or retrofitted the charge port on your own. This was previously a command-line tool in ToolBox3.

In the release notes for service mode, Tesla states: “The charge port door calibration routine (PROC_CP_X_DOOR-SENSOR-CALIBRATION) and charge port latch calibration route (PROC_CP_X_LATCH-CALIBRATION) have been added to the Charging panel. Those routines are required to be run following the replacement of the charge port or charge port door.”

This change only affects the legacy Model S and Model X.

Service Mode+ Updates

The rest of the improvements to Service Mode are exclusive to Service Mode+, which requires a subscription to Tesla’s ToolBox3 software and a connection to a computer. Tesla has added new panels and several improvements to Service Mode+ with update 2025.2.

Accessories Panel - “A new Accessories panel is available to view and change configurations for accessories during retrofits, such as tow package, power liftgate, and soiler. To access the new panel, tap Low Voltage > Accessories.”

Previously, technicians had to manually enter all these configuration changes using the terminal.

This is for all Model 3s and Model Ys.

Signal Viewer Panel - “A new Signal Viewer panel is available to monitor multiple signal values live on a graph. If one or more of the signal values is unavailable, the graph will stop updating. To access the new panel, tap Tools > Signal Viewer.”

This will help technicians diagnose issues in real time when they’re related to signal quality or signal noise throughout the vehicle’s internal electrical systems.

This new panel is available on all vehicles with the AMD Ryzen infotainment processor.

Noise Recording Panel - “To improve the user experience, the recording duration has been decreased to 30 seconds, and reliability of the download routine PROC_ICE_X_FETCH-DIAGNOSTIC-AUDIO-RECORDS has been improved.”

The Noise Recording Panel, which was introduced with the 2024 Holiday Update, has been better tuned to improve technician experience while debugging noises or audio issues within the vehicle.

This particular improvement is only for the Cybertruck.

There’s rarely a software update that goes out that doesn’t include improved or new Service Mode panels. While this update focuses more on improvements to Service Mode+, it still includes other improvements to Service Mode. While these updates are aimed at Tesla technicians and third-party technicians, they also help consumers’ right to repair.

Tesla recently also started selling some vehicle parts directly to consumers through their service catalog.

Police React to Trying Tesla Patrol Vehicles [VIDEO]

Unplugged Performance makes some amazing performance upgrades for Teslas and other EVs. One of their most recent programs is UP.FIT - where they equip Tesla vehicles for police duty.

Law enforcement agencies have highly specific requirements and the UP.FIT program is designed not only to meet those requirements but exceed them. EVs also come with the additional benefits of reducing maintenance, repairs, and fuel costs.

And UP.FIT isn’t just for run-of-the-mill policing, Unplugged Performance also provides upfitted Tesla vehicles, including the Cybertruck, tailored for specialized roles such as tactical and defense applications. Let’s take a look at what real police officers think too.

“The difference is absolutely staggering. I don’t want to go back to this [ICE car] now.”

Hands-On With Teslas

Police officers from eight different departments in California had the opportunity to participate in a unique event at an Emergency Vehicle Operators Course (EVOC) facility. Law enforcement agencies in North America and Europe are beginning to look at EVs more often, and finding a properly up-fitted EV for police work can be a challenge.

“I’ve never driven one until today, I have a different mindset here at 2:00 than I did at 6 a.m. this morning. I was not necessarily sold, but I am now.”

Unplugged Performance let these officers get hands-on with the Model Y Performance, and compare it to the industry-standard Ford Explorer PIU edition. They also got a chance to see some of the other UP.FIT lineup, including the Model S Plaid Interceptor and Cybertruck Patrol Vehicle.

Reactions

The best part of this was the honest, real reactions from the officers who were trying out modified Teslas on the EVOC track.

“I might go buy one now!”

“I’m thoroughly impressed by how it handled and performed. It’s kind of made a believer out of me.”

“First time driving an electric car… The difference between the [Tesla and Ford] is staggering… I didn’t want to be in the Explorer anymore.”

Several comments talked about the handling of the vehicles - how fun they were to drive, how tight they cornered, and how fast they accelerated. They also mentioned that because of that performance - these cars were able to do things that the Ford Explorer just isn’t capable of.

And when doing simulated chases - our favorite comment “It’s like you don’t even have to try!”

Another fun data point that elicited some great reactions was the battery usage of the cars. The Teslas arrived at around 97% state of charge at 6 am, and at 2 pm, the cars still had about 55-60% of the battery left.

You can watch the entire video from Unplugged Performance below.

Teslas Just Make Sense

At the end of the day, the thing is, Teslas - and EVs in general - just make sense for patrol vehicles. Officers can leave the heat or AC running the entire time without having to idle an engine. EVs also perform far better than their ICE equivalents, and they reduce maintenance and fuel costs massively - especially when you can just charge a whole fleet of patrol vehicles overnight.

Many police officers have commented online and mentioned how they burn massive amounts of gas just idling away with their vehicles, which just continuously burns fuel and increases wear and tear on the thousands of components in an ICE vehicle.

On top of that, this sold individual people - not just as officers but as consumers - on the idea of Teslas and EVs. Putting butts in seats in important, and it’s one of the best ways to convince naysayers that the future is already here.
