Because it was based in 2014, Zoox Inc. has labored to deploy custom-built robotaxis on public roads. The autonomous automobiles of Amazon’s self-driving enterprise don’t seem like a mean automotive; they don’t have any steering wheels, brake pedals, or driver’s seats. As an alternative, they’re constructed round cultivating a cushty using expertise.
A {custom} automobile, nevertheless, requires {custom} manufacturing processes. This has led Zoox to open its personal robotaxi serial manufacturing facility in Hayward, Calif., earlier this 12 months. Whereas the firm doesn’t have the benefit of getting a big OEM backing it, Zoox does keep full management over each step of the manufacturing course of.
Michael Lemperle, the senior director of producing engineering and common meeting at Zoox, has spent his total profession within the automotive trade. After serving to fortify Porsche’s manufacturing provide chain for nearly a decade in Germany, Lemperle moved to the U.S. in 2016.
Round this time, Tesla was turning into extra mainstream, and it was clear to Lemperle that the trade was shifting in direction of electrification. There was additionally plenty of rising hype round autonomous automobiles (AVs). Lemperle was drawn to Zoox due to its distinctive automobile design.
“If you wish to ship an impressive or superior service to your buyer, you principally want to actually resolve to combine the entire experience journey,” Lemperle informed The Robotic Report. On the finish of the day, Zoox sells rides, so it’s necessary to construct across the using expertise, he mentioned.
Now, Lemperle has spent over seven years at Zoox, serving to the corporate create its autonomous automobiles with scalability in thoughts.
How is Zoox’s manufacturing line totally different from a mean OEM?
Zoox makes use of its manufacturing facility for quite a lot of operations, together with robotaxi engineering and software program/{hardware} integration, robotaxi meeting, storage of robotaxi elements, transport and receiving, and end-of-line testing.
In relation to the meeting line, Lemperle mentioned Zoox makes use of efficient features of conventional OEM meeting traces. For instance, the corporate companions with suppliers as a lot as doable to ship high-quality elements.
The place Zoox differs is in testing diagnostics and in constructing software-defined automobiles. This implies the corporate places a a lot higher give attention to integration.
“In a conventional OEM, you usually energy up the automobile very late within the course of, and the diagnostics that must occur on {the electrical} system are pretty restricted,” Lemperle mentioned. “For us, it’s precisely the alternative means round. We attempt to energy up very early in order that we will begin testing and discover points as they occur.”
Zoox runs diagnostics each time it installs a brand new part on the automobile. This implies the corporate is consistently checking to ensure an element is linked accurately, if it has the fitting firmware model, or if there are every other faults.
Zoox depends on automation in its facility

As a result of Zoox is operating diagnostics with each part it provides, it takes longer to assemble a Zoox robotaxi than an everyday automobile. On a mean large-scale automotive meeting run, a line runs at about 30 to 60 automobiles per hour, which equates to 1 to 2 minutes of meeting time, Lemperle mentioned.
Zoox, alternatively, takes 20 minutes to assemble a automobile, a lot of which requires a versatile, human operator who can leap between totally different duties shortly. There are, nevertheless, components of the method that require repeated, laborious duties. For these, Zoox employs robotics.
“A terrific instance for that is, we use [automation] for all the urethane shelling out that we do to attach in glass or different panels,” Lemperle defined. “The repetition and continuity {that a} robotic can produce, you’ll be able to’t practice a human to get to that time.”
Zoox additionally makes use of automated guided automobiles (AGVs) in its facility, a know-how that Lemperle famous has matured. Now, AGVs don’t require many infrastructure adjustments, and are simple to scale when wanted, he mentioned.
“It’s extraordinarily versatile and un-invasive from an infrastructure perspective,” Lemperle mentioned.
Fast servicing is vital to scalability, Lemperle says
For Lemperle, scalability was an necessary concern from the very first Zoox prototype. He has labored to construct the automobile manufacturing group from scratch.
“Now, we’re on this very fascinating section, from a automobile manufacturing standpoint, the place our focus is now shifting,” Lemperle mentioned. “The product has reached the maturity that we now, and we’re transitioning into actually ramping up manufacturing and with the ability to, on the similar top quality stage, ship 1000’s of [vehicles] into the fleets.”
However scalability isn’t nearly the way to simply construct a automobile. “For us, as we function the fleet, it’s not solely about how will you construct them simply, but in addition, you do you service them? And, how do you retain service prices down and principally additionally optimize across the uptime of the automobile?” Lemperle mentioned.
He needed to make sure that a Zoox automobile would spend as little time as doable getting serviced at a depot. This was particularly necessary contemplating a robotaxi will drive many extra miles than a mean automobile.
“For instance, there are a few bigger modules. One among them is our drive module that has fairly a little bit of complicated know-how in it; the battery is in there, the GPU is in there,” Lemperle mentioned. “You probably have an issue with that unit, we will pretty simply pull that unit off, put a brand new unit on, and the automobile can exit into the sphere once more and drive.”
The advantages of staying in-house whereas scaling to 10k automobiles
For Lemperle, one of many greatest advantages of conserving all of Zoox’s manufacturing in-house is the flexibility to collaborate throughout departments.
“Protecting that common meeting of the automobile in-house means we will actually have shut collaboration between the totally different engineering groups, like automobile and software program engineering,” Lemperle mentioned. “Our facility is now simply 50 minutes away from our headquarters. So every time we discover points, we will in a short time iterate and actually work via them.”
“It permits us to maintain very tight management of the configuration of the automobile and the variation evolution of the automobile, whereas persevering with to make sure its efficiency,” he continued. “So these fast suggestions loops are actually a key piece of the puzzle. I believe the opposite piece is that this proprietary diagnostic system that we developed to have the ability to absolutely combine that into the meeting line of the testing.”
The firm plans to proceed to weigh which items it desires to maintain making in-house and which elements it could actually outsource.
“We will produce greater than 10,000 automobiles out of this facility in a 12 months,” mentioned Lemperle. “So we’re clearly already placing thought into what comes after this.”
“There are specific items proper now, trying on the automobile that we construct ourselves, the place we would say, okay, most likely a provider may have performed this higher,” he concluded. Trying to outdoors sources will assist Zoox give attention to what it does finest: integrating complicated programs into one, user-focused robotaxi.
