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 Adds Steering Wheel Guides for All Wheels in FSD 12.5.2

By Karan Singh

Tesla’s latest FSD update, version 2024.27.5 brings some improvements when parking your vehicle. This is another undocumented, but one we’re happy to see.

Most recently, the Cybertruck received the undocumented change for the Hands-Free Frunk opening (video below). The Cybertruck also recently received Vision Park Assist, which included steering wheel guides in the visualization showing the direction the front and rear wheels were turned. However, it turns out this isn’t just for the Cybertruck.

Update: We’ve updated this article to mention that this feature isn’t included in update 2024.32 yet.

Parking Improvements

Due to the Cybertruck’s unique rear-wheel steering and steer-by-wire design, Park Assist in the Cybertruck displayed the path of the front wheels, and how they would swing while reversing.

This enhancement is also coming to every Tesla vehicle in FSD 12.5.2 and later. It’s also expected to be available in a future update for non-FSD vehicles. However, it’s unclear whether it will be a later revision of update 2024.32 or the next major Tesla update. This is a neat little update, as it helps drivers better understand and predict the path their vehicle will take during a turn.

Brandon, going by @teslaflexx on X, originally spotted the new visuals recently on an AMD-based Model Y running 2024.27.5 and FSD V12.5.2.

Any vehicles who are on update 2024.27.5 or 2024.27.20 should have access to this new feature.

Tesla to Sell Cybertruck Battery Armor and Rock Sliders for Cybertruck

By Karan Singh

Tesla’s Cybertruck has been used as an awesome off-road vehicle so far, with some great videos from both Tesla themselves, as well as many owners who have been challenging difficult off-road obstacles.

One frequently requested feature, however, is additional armor for the Cybertruck to improve its off-road capabilities. Wes Morril, Program Manager for the Cybertruck, has confirmed that Tesla will be introducing Battery Armor and Rock Sliders as retrofit “options” by the end of 2024.

Battery Armor

The Cybertruck’s underbody plate, while not completely unarmoured, isn’t exactly super thick, and can leave the battery exposed if the weight of the truck is left on a high-center point or a sharp rock. This upcoming battery armor will be similar to the armored undersides offered by other companies specifically for off-roading.

Rivian, for example, sells armor as a single package for $3,950 USD, or $5,800 CAD, along with a 20” wheel upgrade, full-size spare, and a utility panel including an air compressor and enough hose to let you reach any of the tires when airing up or down your tires for off-road. Tesla’s upcoming Battery Armor will be a retrofit option, unlike Rivian’s – which can only be added when purchasing the vehicle.

Rock Sliders

The Cybertruck has a simple and clean bottom corner – but that also means that it exposes the plastic trim directly. Rock sliders go on the bottom edge of off-road vehicles between the wheels to protect the vehicle's body. Rock sliders are a pretty common modification, and some companies have already begun to offer them for the Cybertruck – but a first-party OEM option is always best.

This is especially true since most third-party options use the lift points of the vehicle to attach rock sliders, which can make replacing wheels or lifting the vehicle difficult without removing the third-party additions. This adds considerable time to what should be a quick job.

Release Date

We’re looking forward to Tesla bringing these options to the Tesla store in the coming months. Wes said they’d be available as retrofits before the end of 2024, along with the upcoming Winter Tire Package, which is arriving next month. The Winter Tire Package is already available to order for Cybertruck owners.
