Because it was based in 2014, Zoox Inc. has labored to deploy custom-built robotaxis on public roads. The autonomous autos of Amazon’s self-driving enterprise don’t seem like a median automotive; they don’t have any steering wheels, brake pedals, or driver’s seats. As a substitute, they’re constructed round cultivating a cushty using expertise.
A {custom} automobile, nonetheless, requires {custom} manufacturing processes. This has led Zoox to open its personal robotaxi serial manufacturing facility in Hayward, Calif., earlier this yr. 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 basic 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 the direction of electrification. There was additionally a variety of rising hype round autonomous autos (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 essentially resolve to combine the entire trip journey,” Lemperle advised The Robotic Report. On the finish of the day, Zoox sells rides, so it’s vital to construct across the using expertise, he mentioned.
Now, Lemperle has spent over seven years at Zoox, serving to the corporate create its autonomous autos with scalability in thoughts.
How is Zoox’s manufacturing line completely different from a median OEM?
Zoox makes use of its manufacturing facility for a wide range 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.
Relating to the meeting line, Lemperle mentioned Zoox makes use of efficient facets of conventional OEM meeting traces. For instance, the corporate companions with suppliers as a lot as potential to ship high-quality elements.
The place Zoox differs is in testing diagnostics and in constructing software-defined autos. This implies the corporate places a a lot larger deal with 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 manner 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 appropriate firmware model, or if there are another faults.
Zoox depends on automation in its facility

As a result of Zoox is working diagnostics with each part it provides, it takes longer to assemble a Zoox robotaxi than a daily automobile. On a median large-scale automotive meeting run, a line runs at about 30 to 60 autos per hour, which equates to at least one to 2 minutes of meeting time, Lemperle mentioned.
Zoox, however, takes 20 minutes to assemble a automobile, a lot of which requires a versatile, human operator who can bounce between completely different duties shortly. There are, nonetheless, elements of the method that require repeated, laborious duties. For these, Zoox employs robotics.
“An amazing instance for that is, we use [automation] for all the urethane meting 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 autos (AGVs) in its facility, a expertise that Lemperle famous has matured. Now, AGVs don’t require many infrastructure adjustments, and are straightforward 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 vital 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 prime quality degree, ship hundreds of [vehicles] into the fleets.”
However scalability isn’t nearly how you can 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 potential getting serviced at a depot. This was particularly vital contemplating a robotaxi will drive many extra miles than a median automobile.
“For instance, there are a few bigger modules. Certainly one of them is our drive module that has fairly a little bit of complicated expertise in it; the battery is in there, the GPU is in there,” Lemperle mentioned. “When you’ve got 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 autos
For Lemperle, one of many largest advantages of conserving all of Zoox’s manufacturing in-house is the flexibility to collaborate throughout departments.
“Retaining that basic meeting of the automobile in-house means we will actually have shut collaboration between the completely different engineering groups, like automobile and software program engineering,” Lemperle mentioned. “Our facility is now simply 50 minutes away from our headquarters. So at any time when we discover points, we will in a short time iterate and actually work by way of 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 needs to maintain making in-house and which elements it could outsource.
“We are able to produce greater than 10,000 autos out of this facility in a yr,” mentioned Lemperle. “So we’re clearly already placing thought into what comes after this.”
“There are particular items proper now, trying on the automobile that we construct ourselves, the place we would say, okay, in all probability a provider might have performed this higher,” he concluded. Trying to outdoors sources will assist Zoox deal with what it does finest: integrating complicated techniques into one, user-focused robotaxi.
