SpaceX installs first ‘Mechazilla’ arm on Starship launch tower
One month after SpaceX stacked Starship’s South Texas ‘launch tower’ to its full height, the company has installed the first arm on what amounts to the backbone of ‘Mechazilla.’
At the end of July, after less than four months of work, a team of SpaceX workers and contractors installed the final prefabricated section of a ~145m (~475 ft) tall tower meant to support orbital Starship launches. Above all else, SpaceX’s first custom-built ‘launch tower’ is a sort of backbone or anchor point for several massive, mechanical arms that will accomplish the actual tasks of servicing – and, perhaps, catching – Starships and Super Heavy boosters.
Work on all three of the arms expected to make up what SpaceX CEO Elon Musk has described as “Mechazilla” has been visibly underway since the last week of June as a small army of welders carefully assembled dozens of sections of heavy-duty steel pipe into house-sized frames. Almost exactly two months later, SpaceX has installed the first of those three arms on the exterior of Starship’s skyscraper-sized launch tower.
Known as the tower’s quick-disconnect or QD swing arm, the standalone structure is reportedly designed to accomplish a few different tasks. First, as its unofficial name might suggest, the QD arm will hold a quick-disconnect umbilical connector that will temporarily attach to the base of Starships to load them with fuel, oxidizer, and other consumables and link them to ground power and networking. For years, it appeared that SpaceX planned to fuel Starship upper stages through their Super Heavy boosters, which will themselves be connected to umbilical panels on a table-like launch mount that sits beside the tower.
However, once work began on Starship S20, the first potentially space-capable prototype, it was clear that SpaceX had foregone the umbilical plate normally installed at the base of Starship skirts and moved that connection to the ship’s lower back. Musk later confirmed as much in interviews and tweets, revealing that longstanding plans to dock Starships aft to aft for in-space refueling were also up in the air. As of late, aside from reiterating that the launch pad itself (“Stage Zero,” per Musk) is even more complex and difficult than Starship or Super Heavy, SpaceX’s CEO has also repeatedly stated a desire to offload as many systems as possible onto the launch pad – seemingly regardless of the complexity of the alternative.
Enter the building-sized robot informally known as Mechazilla. While the relatively simple swinging ‘QD arm’ that will fuel Starship and stabilize both stages of the rocket is a common feature of rockets and launch pads, the only experience SpaceX itself has with umbilical swing arms is the Crew Access Arm (CAA) that allows astronauts and cargo to board Dragon spacecraft after Falcon 9 goes vertical – a structure with near-zero umbilical utility. Technically, the transporter/erectors (T/Es) that cradle Falcon rockets, lift them vertical, and fuel them before launch have some similarities with swing arms but SpaceX has always used simpler and more reliable passive mechanisms whenever possible.
A step further, though, SpaceX has also seemingly foregone the installation of a basic crane on top of its Starship tower and Musk himself has developed an almost infamous aversion to the inclusion of something as seemingly simple as landing legs on Super Heavy boosters – and, eventually, perhaps even (some) Starship variants. Instead of adding rudimentary legs to Super Heavy prototypes, Musk has seemingly pushed SpaceX to turn Starship’s launch tower into a complex, vulnerable, and fragile rocket recovery system. Beyond the comparatively mundane QD arm, Musk says that SpaceX will ultimately install a pair of massive house-sized steel arms mounted on a sort of external elevator. Those arms will apparently be capable of actuating and moving up and down the tower with the speed, precision, and reliability needed to quite literally catch Super Heavy boosters – and, eventually, Starships – out of mid-air.
The team tasked with designing and building those rocket-catching arms have affectionately deemed them “chopsticks” – a nod towards the kind of nuanced actuation they’ll need to recover the world’s largest rocket boosters and upper stages without missing or destroying them. Having really only just perfected propulsive vertical landing with Falcon 9 and Falcon Heavy boosters, SpaceX thus intends to throw a few extra points of failure into the mix.
To SpaceX and Musk’s credit, whether the company’s second attempt at catching rockets goes as well as the first, some version of the massive ‘chopstick’ arms SpaceX is working on was likely going to be necessary just to rapidly turn around boosters and Starships – and do so regardless (within reason) of weather conditions. By replacing a tower crane with giant arms, SpaceX will hopefully be able to stack Starship on Super Heavy (and Super Heavy on the launch mount) even in the high winds that are almost always present on the South Texas Gulf Coast. If SpaceX can also reliably catch boosters with those arms, it could be a significant upgrade for the operations side of Starship reusability. For now, though, only time will tell.
Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.

Tesla Cybertruck targets job site crews with new Tailgate Utility Track and Bed Gear Box accessory
Tesla launched a $350 tailgate track and a $985 lockable Bed Gear Box for Cybertruck.
Tesla’s Cybertruck team added two more items to the Tesla Shop, targeting job site crews and owners who use the truck bed for actual work rather than just showing it off. The official Cybertruck X account posted the Tailgate Utility Track and the Bed Gear Box within minutes of each other, part of a five item batch that also included a reflective jacket, a spray paint hat and an updated reflective tee.
The Tailgate Utility Track runs $350 and turns the folded down tailgate into another mounting surface. It’s a single aluminum track with a T-slot for sliding accessories and two L-track attachment points, plus two load stops included in the box. The pitch is straightforward: strap down oversized cargo, like lumber or a cooler, that hangs off the back of the bed without it sliding out mid-drive. It bolts onto the existing tailgate and works on every Cybertruck trim.

The Bed Gear Box costs $985 and is a different kind of accessory. It’s a lockable aluminum storage box, 55.78 inches long, 19.8 inches wide and 7.79 inches tall, that mounts to the bed’s L-track rails and comes with two internal bins for smaller items. According to Tesla, at just over 57 pounds empty, it’s meant to stay in place rather than come in and out with each trip, giving owners a factory-fit alternative to loose totes for tools, recovery gear or emergency supplies. Tesla’s listing notes that Long Range and Dual Motor AWD Cybertrucks need the L-Tracks accessory installed separately before the Gear Box will mount, since L-tracks come standard only on certain configurations.

Both accessories lean on the idea Tesla has been building toward since Elon Musk first described the Cybertruck’s third-party attachment strategy at the 2023 shareholder meeting, when he said the truck would ship with mounting points so outside companies, and Tesla itself, could keep adding gear without redesigning the bed. That’s the same L-track backbone underneath the tailgate shield and jumpseats Tesla launched last year, and the off-road armor package that arrived through the same X account in 2025.
Owners looking to round out the rest of the L-track ecosystem, cargo dividers, MOLLE panels, bed racks and similar gear, can find a wider range of options through our Cybertruck accessories collection.
