The Robotic Report lately sat down with Indy Autonomous Problem co-founder and CEO Paul Mitchell to compensate for the most recent information in regards to the self-driving race collection and what we are able to anticipate to see within the coming 12 months.
The Indy Autonomous Problem (IAC) went worldwide for the primary time with an occasion on the Milan Monza Motor Present in Italy earlier this 12 months. Are you able to give us an replace on how that occasion went?
We made the choice to go to Monza in Italy, and this wasn’t a simple choice, as a result of till now, we’ve solely run the vehicles on ovals. The groups had been tuning their AI drivers to grasp oval racing and the complexities of optimizing driving at velocity on ovals.
We might have continued the competitors on ovals and begun so as to add extra vehicles on the observe on the similar time. Or we might pivot and exhibit that one of these competitors may be executed successfully on highway programs.
Paul Mitchell, CEO of the Indy Autonomous Problem
This choice is extra analogous to our main goal, which is methods to obtain excessive velocity and autonomy at scale in a approach that may enhance freeway security. So highway programs are clearly a greater proxy for that.
Our choice was mission-oriented; it wasn’t nearly going to Europe. Whereas it’s enjoyable to go to Europe, and it’s enjoyable to run on a well-known observe, it actually began with the query: “Ought to we go to highway programs?”
Our authentic competitors was held at Indianapolis Motor Speedway [IMS], and in case you’re going to do one thing for the primary time, there’s this type of thrilling, historic impression of doing it on the oldest and most storied venues. So for ovals, that’s IMS, and for highway programs, that’s Monza.
Did you seize the eye of the worldwide automotive world at Monza?
Proper. First, we needed to get the vehicles and the groups accustomed to the highway course. Rather a lot went into getting the vehicles prepared for the highway, together with modifications and setup to run on a highway course as a substitute of ovals. Groups needed to get conversant in the road-course format.
We felt prefer it made sense for the primary competitors to only be time trials, much like what ended up occurring in Indianapolis the primary time we ran there.
The groups encountered some new challenges, notably across the reliability of localization by GPS. There are two bridges at Monza, after which there are a few sections with vital timber near the observe. Down the principle straightaway, the infrastructure of the suites and the F1 paddock areas hangs over the observe. So you find yourself with some completely different GPS useless spots popping out of the pits.
This required groups to make changes to their software program to have the ability to handle localization utilizing different strategies past GPS, which they finally found out.
We set a variety of data in the course of the occasion. I believe we had speeds that reached 274 kph [170 mph]. We had three groups that went into the ultimate spherical of the time-trial competitors separated by solely perhaps 12 seconds. They had been all hovering proper round 2 minutes and pushing 2 minutes and 10 seconds. Ultimately, I believe the profitable time was round 2 minutes and 5 seconds.

The opposite factor that we observed was that there was numerous enthusiasm from most people of all ages in Italy to have a look at these vehicles and study them and be uncovered to autonomous expertise. For a lot of of them, it might need been the primary time they’d encountered or seen an autonomous car.
Autonomous automobiles aren’t as commonplace within the Milan space and even in Europe. There are most likely some sections in Germany the place they’re performing some testing. However you don’t have Waymo and Cruise doing public pilots in several communities. So I believe there was a fascination with that.
Then the applying of autonomous expertise to one thing that’s very close to and expensive to the hearts of the Italian normal public of racing, I believe [that] was fascinating. We had been a part of the Milan Monza Motor Present. It’s a terrific instance of an open-air motor present that was actually launched, popping out of COVID, proper as completely different auto reveals seemed for tactics to be protected and related.
The organizers selected to create this outside pageant that basically was constructed across the racetrack. About 60,000 individuals got here out throughout the three days, and possibly all of them in some unspecified time in the future noticed the vehicles [on the track] or got here into the storage and checked out them. There was a fairly fixed line of individuals watching the groups engaged on the vehicles or watching when ran the vehicles two occasions a day every day for the three days.
There have been some great supercars from McLaren, Bugatti, and Lamborghini and every kind of actions, meals, and bands and different issues to do. So the truth that individuals discovered it fascinating sufficient that almost all of them got here in and sat down and watched the finals was fairly cool.
It actually was aided by the truth that the profitable staff was once more the native staff from Politecnico di Milano, which has now received three occasions in a row. That didn’t damage by way of producing some native enthusiasm.
We’ve already publicly stated we’re going again in June 2024. We’ve got some planning on doing as a result of they’re performing some building on the Autodromo Nazionale Monza. The plan is to take the competitors to the following stage, with extra multi-vehicle racing versus the single-car, time-trial mannequin.
So that you’re following the identical stepwise formulation that you simply’ve adopted on the oval to extend the problem in complexity whereas enhancing the car’s functionality? You’ve changed among the base car elements with extra highly effective, extra succesful options. Are you able to stroll us by the Indy Autonomous Problem’s revised expertise stack?
We’re going to essentially roll it out and discuss it in depth throughout CES. What I can share is a bit of bit higher-level versus entering into the precise configuration. I can speak in regards to the firms which are contributing expertise that’s both new or the place we’ve upgraded components.
We developed the autonomous race automobile that we’ve been working by a partnership with Clemson College’s Middle for Automotive Analysis, Worldwide Middle for Automotive Analysis, again in 2019. It was type of a world-first; there had been some autonomous automobiles that had been run at larger speeds by the Roborace initiative that preceded the Indy Autonomous Problem. And a few of our groups had participated in that.
Nonetheless, IAC was the primary time that autonomous race vehicles had been constructed to be similar on the bodily race platform. We additionally didn’t understand how the software program and elements would maintain up beneath real-world race circumstances. Frankly, when it was being designed, there was no expectation that these vehicles had been going to be run past October of 2021, once we had the million-dollar prize competitors at IMS.

This preliminary occasion was adopted by the occasion at CES 2022, and since that point, these automobiles have raced greater than 11,200 km [7,000 mi.]. So it was time to improve the vehicles, not simply from a efficiency standpoint, but additionally from a upkeep and tuning perspective, given the cruel working circumstances.
We’ve constructed up the interior engineering capabilities right here in Indianapolis, which is the racing capital, no less than within the U.S. That is the place there’s numerous engineering know-how round automotive and the place numerous the elements and methods are literally designed, engineered, and manufactured. All the car elements are sourced domestically.
The query was: How can we make these vehicles extra serviceable and extra sturdy? Can we use fewer components? Can we cut back the variety of connections and the variety of wires and thus cut back the variety of failure modes and ache factors which may exist?
Proper after the primary occasion at Indy, we realized that some modifications had been obligatory as a result of sure elements had been breaking down. So we made the swap to the dSPACE Autera central laptop.
However this 12 months was an opportunity to step again and utterly redesign the entire controls structure. One of many cool tales is that Janam Sanghavi, who led the trouble at Clemson, is now our director of auto engineering.
He was the lead scholar of the student-led staff on the Clemson Deep Orange program that designed the primary prototype for the Indy Autonomous Problem vehicles. So for him, it was a terrific alternative to return and replace issues that he discovered by the method.
The story is basically about enhancing the sturdiness, performance, accessibility, and serviceability of the system as a result of these vehicles wreck rather a lot. And after they have wrecked, we’ve been in a position to not have an excessive amount of harm to the autonomous methods within the cockpit.
Nonetheless, as speeds enhance, and as wrecks turn out to be extra energetic, it’s inevitable that there’s going to be extra strain on these methods within the cockpit.
Then the opposite storyline is upgrading and altering the core elements within the autonomous stack. First, the expertise that was accessible in 2019 and 2020 is completely different than the expertise that’s accessible immediately. That’s an indication of simply how shortly this trade is progressing.
For instance, the Hydra lidar from Luminar is not in manufacturing. So we’re switching to the Iris lidar from Luminar.
Then, we modified to a extra upgraded radar system from Continental. We’ve been ready on that for a short time. So we knew that we had been going to try this with Continental, even again final 12 months when it got here on as a accomplice of IAC. However we’re lastly getting these radars built-in into the automobiles.
We’re working with the distributors to maybe transfer to a more recent model of the cameras. The cameras have been working fairly nicely for us. The variations within the expertise might not be as excessive as what you see within the distinction between lidar a couple of years previous and now, nevertheless it’s nonetheless significant.
The central laptop stays the identical — it’s nonetheless the dSPACE Autera product. We’re sticking with that as a result of it’s been a terrific answer for us. We’ve got upgraded networking and communication expertise from Cisco.
We’re additionally implementing a brand new race-control answer from Marelli, which we piloted at Monza, and it labored nice for us. However now we’re actually, absolutely integrating that into the vehicles. It’s the identical telemetry, communication system, and race management software program system that’s utilized in System 1. In order that’s thrilling to have that on the automobiles.
And that permits the Indy Autonomous Problem to do some cool issues round larger automation of race management that may mirror the automation of the drivers.
The opposite vital change is to the drive-by-wire methods. So I believe we discovered by our journey that drive-by-wire methods aren’t one thing that you may simply take off the shelf and placed on to an utility like a race automobile, and since it’s labored on a passenger automobile, it’s going to work effective on a race automobile.
A part of IAC’s objective is to see what can you’re taking off-the-shelf {hardware} and software program that’s utilized in autonomous automobiles immediately, and see how will it maintain up at 240 KPH (150 MPH) or larger. The physics of the high-speed racing use case is simply completely different than the physics of a passenger automobile or business car. You need to measurement the actuators to have the ability to cope with that.
The drive-by-wire system that’s going into the car is definitely one thing we’ve designed internally, by the Autonomous Problem. We labored with some completely different distributors, however the choice of the actuators, the design integration, and the software program issues that we’ve executed, are particular to this race automobile.
Underneath race circumstances, you need every staff to have the steering and braking be responsive. So we’ve put numerous time into that in order that the groups aren’t combating the management infrastructure.
Dallara AV-23 technical specs
The Indy Autonomous Problem stated the Dallara AV-23 transformation can be executed earlier than the tip of 2023. It is going to be accomplished in phases to permit for testing and validation of recent and up to date methods. Along with a brand new central laptop from dSPACE and new GPS methods from VectorNav, different expertise that can be enhanced with the AV-23 consists of:
- New radar sensors from Continental
- Up to date lidar methods from Luminar
- Enhanced communications and networking options from Cisco
- Cloud computing and information analytics from Amazon Net Companies
- Superior racing tires able to each oval and highway course efficiency from Bridgestone
- On-board supercomputer from dSPACE
- GPS/GNSS connectivity from VectorNav
- Aero equipment and different car system modifications from Dallara
As you proceed to push the race vehicles to larger speeds, you must predict the place that is going to go subsequent. Would you like this platform to have some life to it?
This is without doubt one of the issues we’ll discuss once we get to CES in January. We’ll have the ability to discuss among the enjoyable stuff with a drive-by-wire system that’s, let’s say, “uniquely related” to autonomous automobiles.
So there are options we’ve included {that a} human-driven car wouldn’t do, or would or wouldn’t be potential due to the operator being, a human being with two ft, not 5 ft or six ft.
So are you hinting that the brand new platform will allow outputs that exceed what a human might do within the driver’s seat?
Proper. And I don’t assume we had been actually optimizing for that beforehand. In the event you’re going to do an autonomous car, you’re attempting to exhibit the complete potential of autonomy then you must put in actuators and methods that give larger freedom for inputs and instructions that in any other case aren’t accessible once you’re speaking a couple of human operator.
We’re preserving with the VectorNav GPS system. That was a change we had made mid-journey. They weren’t on the unique automobile, however we’ve added them. So GPS GNSS stays the Vector Nav system that we had placed on the vehicles, however with some new wiring, after which numerous it’s round packaging the controls in a greater approach.
There’s automotive Ethernet now; that’s type of a brand new factor. So we’re utilizing that the place it is smart, along with much more sturdy connectors which are accessible for autonomous automobiles immediately than there have been in 2019. The reliability of connectors and decreasing the variety of connectors — or failure factors — are key to the general reliability of the car.
This next-gen system shouldn’t be a brand new form-factor racecar however is an overhaul of the autonomous methods whereas balancing the modifications, in order to not set the groups again by way of having to begin from the bottom up with the coding of their software program and their AI drivers.
Are you able to replace us on the IAC’s area of rivals for subsequent 12 months?
We nonetheless have 9 groups. I believe there’s there’s a tenth staff that’s lurking that has expressed its intention to take part.
We’ve had some extra universities come on. I believe we’re as much as 18 universities now that make up these 9 groups. A few of these bulletins will occur between now and CES. Some groups taking up extra college companions. In some instances, there was a change in management of an present staff.
A number of U.S. establishments have expressed curiosity in getting concerned. I believe they’re most likely seeing the success of the European groups and saying, “Hey, what about us? We need to become involved.” In some instances, they need to collaborate with the European and Asian groups.

How necessary is U.S. automotive competitiveness to the Indy Autonomous Problem?
We’re based mostly right here within the U.S. Clearly, an enormous a part of our mission as nonprofit group is advancing the automotive trade. We need to achieve this in a approach that helps the U.S. and our allies stay aggressive.
On this international atmosphere, there’s much more exercise immediately than there was once we acquired began on this area of high-speed automation. We’re additionally seeing a lot, rather more interplay between tutorial establishments and the trade and even the protection neighborhood.
A few of our groups have partnerships with DoD, and European groups have partnerships with their protection communities. The event of AI-based, high-speed algorithms and automobiles which are able to working autonomously [has] turn out to be an space of IP improvement and competitiveness.
Once we first began, it was only a query of “Are you able to really make an autonomous automobile go actually quick and construct a race automobile that may drive itself?” And as soon as the reply is “Sure,” and also you’ve confirmed that to the world, then that opens up a brand new class of competitors and new curiosity from nation-states and completely different teams.
I believe you’ll see some continued collaborations that we’re attempting to determine round utilized analysis and expertise improvement and IP improvement between the schools which are a part of the IAC, We need to achieve this in a approach that helps the the industries within the U.S., Europe, and components of Asia, notably South Korea and Japan.
What you possibly can inform me about modifications to the competitors we’ll see at CES 2024 in Las Vegas?
There received’t be numerous modifications to the competitors as a result of Vegas is the final time that the legacy vehicles are working. The subsequent-gen Dallara AV-23 car will debut at CES 2024. We anticipate to have three of them working on the observe and doing exhibition testing and validation.
However on the observe and within the competitors, we could have lthe present AV-21 vehicles that among the groups can be utilizing in a passing competitors that’ll be in the same format to what we at CES 2023.
And the logic there was that we didn’t need to construct all the brand new race vehicles and roll them out and take a look at them for the primary time in Las Vegas. We wished to take action iteratively.
So we requested the groups who wished to concentrate on shakedown and improvement of the brand new automobile and testing and validation, and who wished to run one other spherical of competitors. We had some groups that haven’t actually been in a position to shine as a lot as they’d prefer to in these competitions. So that they have opted for the passing competitors, after which a couple of of them stated they had been keen to begin engaged on the brand new automobile.
We’ve structured it in such a approach that the learnings on the brand new automobile are going to be shared amongst all of the groups, after which everybody goes to get entry to the brand new vehicles after CES. We must always view the vehicles which are debuting within the West Corridor at CES as static, with some lively demonstrations.
Utilizing what we study at Vegas, we’ll make any remaining changes earlier than we convert all of the automobiles to the brand new next-gen system and switch them over to the groups to begin actually practising in earnest for Monza and the remainder of this schedule for subsequent 12 months, which we’ll be asserting at CES.
So there could also be extra Indy Autonomous Problem races than simply Monza in 2024?
Sure, there’s going to be one other main race after Monza subsequent 12 months. And there’ll be some thrilling information at CES about how these races can be linked. So some enjoyable, historic context, matching the previous and the brand new with an occasion at Monza and one other occasion again within the U.S. We’ll roll that out at CES.
We’re additionally altering the occasion schedule for the racing at CES to allow attendees to not solely see the beginning of the racing, but additionally be there for the ultimate heats when the racing actually will get thrilling, in addition to run beneath the lights. So in case you’re going to Las Vegas for CES 2024, make sure to stick round till Saturday for the Indy Autonomous Problem @ CES occasion.
