When Vandi Verma noticed the Spirit and Alternative rovers land on Mars whereas she was working towards a Ph.D. in robotics, it set her on a path towards working at NASA in area exploration. Maybe unsurprisingly, at this time, as chief engineer for robotic operations at NASA’s Jet Propulsion Laboratory (JPL), Vandi sees the most important alternatives for synthetic intelligence in robotics and automation.
On this episode of the Me, Myself, and AI podcast, she describes the methods wherein the Mars rovers depend on AI, together with the know-how’s use in digital twin simulations that allow JPL scientists to apply their driving abilities earlier than truly controlling the rovers on Mars. She additionally discusses with hosts Shervin Khodabandeh and Sam Ransbotham how NASA’s use of AI — and its strategy to danger — supply classes for organizations that want to simulate real-world eventualities right here on Earth.

Shervin Khodabandeh: What can we study from the usage of AI on Mars? Discover out on at this time’s episode.
Vandi Verma: I’m Vandi Verma from NASA JPL, and also you’re listening to Me, Myself, and AI.
Sam Ransbotham: Welcome to Me, Myself, and AI, a podcast on synthetic intelligence in enterprise. Every episode, we introduce you to somebody innovating with AI. I’m Sam Ransbotham, professor of analytics at Boston School. I’m additionally the AI and enterprise technique visitor editor at MIT Sloan Administration Evaluation.
Shervin Khodabandeh: And I’m Shervin Khodabandeh, senior accomplice with BCG and one of many leaders of our AI enterprise. Collectively, MIT SMR and BCG have been researching and publishing on AI since 2017, interviewing tons of of practitioners and surveying 1000’s of firms on what it takes to construct and to deploy and scale AI capabilities and actually remodel the way in which organizations function.
Sam Ransbotham: Hey, everybody, welcome. Right this moment, Shervin and I are actually loopy excited to be speaking with Vandi Verma, the chief engineer at NASA’s Jet Propulsion Laboratory. It’s actually cool stuff. Vandi, from the sneak preview that we had, we’re actually excited to have you ever on the present. Thanks for taking the time to speak with us.
Vandi Verma: Thanks for having me right here.
Sam Ransbotham: I admit I’m actually geekily fascinated by your job — I’m positive everyone seems to be — however let’s clue in all people on what you do. Are you able to begin by giving an summary of JPL normally and your explicit function?
Vandi Verma: I’m the deputy supervisor for the Mobility & Robotics system at NASA’s Jet Propulsion Laboratory, and I’m additionally [working] with the chief engineer for the Mars 2020 mission, which consists of the Perseverance rover and the Ingenuity helicopter.
JPL is a NASA middle that focuses on constructing robots for area exploration. And NASA’s mission is to discover, uncover, and increase information for the advantage of humanity, and what we do is the robotics facet of that.
Shervin Khodabandeh: Whenever you say “robotics,” I take into consideration synthetic intelligence, however Mars missions seem to be a really difficult place for brand spanking new applied sciences like AI. How are you and JPL utilizing AI in what you’re doing with robotics?
Vandi Verma: Proper. AI has kind of reworked what we name that over a time frame, and there are issues that we do on the bottom, and there are issues that we do onboard our robots, and so I’m going to the touch on a few of these. So, normally, we’re extra on the facet of autonomous functionality — nearer to what you may consider as what self-driving vehicles use — and never quite a lot of it’s probably classically machine studying per se, though we use that to tell quite a lot of our work.
In actual fact, with Perseverance, 88% of the driving that we’ve executed is autonomous driving. And so the rover has cameras: It’s taking the pictures; it’s detecting the terrain and determining what’s hazardous and navigating round obstacles. And it’s truly fairly fascinating as a result of it’s driving on terrain that no human has ever seen, so we will’t even give it that type of data. So that’s positively a type of autonomous navigation.
We additionally, on the finish of drives, are attempting to make quite a lot of progress as a result of we’re on this actually harsh setting and we’ve a mission to gather and cache a sure variety of samples with Perseverance, as a result of for the primary time, we are literally going to carry them again to Earth. However we would like them to be from as distinct locations as doable, so we need to do quite a lot of driving. In case you cease on a regular basis, you’re not going to make as a lot progress. However who is aware of if there’s one thing actually thrilling alongside the way in which that we’re simply going to overlook? In our world, we name it the dinosaur bones.
We’ve AI capabilities on the rover the place it’ll take a wide-angle picture, take a look at a big swath of terrain, after which strive to determine what’s the most fascinating characteristic in there. We’ve a complete slew of devices, however one of many devices is the SuperCam instrument, which does lots. It has a laser, and from a distance, you possibly can shoot a laser at a rock, and it creates a plasma, and we examine that with a telescopic lens. That’s such a slender subject of view — , a milliradian — and so if you happen to had been to attempt to do this to the entire view you see, you’d spend days there.
And so primarily, we use the AI to determine “What’s essentially the most fascinating factor that we must always zap?” After which you possibly can ship the info again and inform the scientists on Earth. That’s been very helpful as effectively. So we do this.
After which, , there’s planning. There are quite a lot of sources we use, from issues like … totally on Mars, when you could have a spacecraft, the setting is harsh. So [we’re] enthusiastic about “How do you warmth issues — maintain it on the proper temperature? How a lot energy do we’ve?” You want to talk with Earth; the place’s Earth? We even have planning onboard, which thinks of issues extra by way of kind of the larger image. So all of these types of issues are examples of what we do.
Sam Ransbotham: That’s a ton of examples there. And the truth that you’re predominantly driving autonomously — it looks like an enchanting world. You talked about discovering one thing fascinating. What’s the goal operate there? How do you determine that one thing is fascinating? I do know what I feel is fascinating, however inform me about that course of of getting a machine work out what’s fascinating.
Vandi Verma: I feel one of the crucial fascinating issues about defining what’s fascinating is that it places it on the people. We even have a extremely arduous time telling machines what we would like them to do, proper? To ensure that us to inform what’s fascinating, we’ve quite a lot of completely different parameters that scientists can use to specify “I’m in search of light-toned rocks of a specific measurement, of a specific albedo and form, which can be fascinating on this space.” And we will change that. So we’ve these completely different templates, relying on the terrain we’re in, that scientists on the bottom assist us decide. We ship that to the robotic to say, “We’re in search of this sort of factor.”
We’ve executed some analysis as effectively the place we inform it, “You now observe the entire issues we’ve seen” — it’s known as novelty detection, which we don’t truly but have deployed, however “Discover what we haven’t already checked out.” That’s one other one.
However there are two issues in right here. After we’re doing exploration, we’re in search of issues which can be new, however we additionally attempt to characterize issues we’ve seen with a number of completely different devices, as a result of we are attempting to gather a statistically vital quantity of knowledge for the speculation we’ve. We’re making an attempt to determine “May life have existed on Mars and, particularly, historical life?”
And in order that puzzle … There are hypotheses, and also you’re making an attempt to reply particular questions, and that’s what the scientists then will inform the robotic that they’re occupied with. We’ve truly used supercomputers to translate that into parameters that we will then uplink to the robotic.
Sam Ransbotham: So the individuals type of describe in tough phrases what they need, and you then’ve acquired some supercomputer, one thing right here on Earth, making an attempt to translate that right into a set of parameters that you just then ship to the rover to determine what to search for. Did I perceive that appropriately?
Vandi Verma: That’s proper. And that is, I feel, an space the place AI can assist lots as a result of we’re nonetheless in that section in robotics in quite a lot of areas the place we’ve quite a lot of knobs. We are able to do lots, however the artwork is in tuning this multivariable area. In actual fact, , simply on Perseverance — we name them parameters in software program, [and] this isn’t even making an allowance for {hardware} design and different issues — we’ve over 64,000 specific parameters. These are saved in nonvolatile reminiscence. This isn’t even making an allowance for the arguments to instructions you possibly can ship. So there’s simply so some ways in which you’ll categorical what you need to say, and that’s the place we will use quite a lot of functionality to know what the appropriate mixture is for what we meant to do.
Sam Ransbotham: Yeah, the combinatorics on one thing like that simply seem to be they might explode, so it looks like a fantastic device for machine studying and to determine what’s the appropriate set of optimum parameters or subsequent parameters to decide on when you could have that many to select from. Such as you mentioned, you possibly can’t laser all the floor of Mars. Nicely, you can also’t discover 64,000 parameters on the identical time.
Vandi Verma: Yeah, you’re completely proper. And but, the problem and the sweetness — what makes it such a enjoyable setting to be in — the margin for error may be very low, so you can not experiment when it’s so arduous to get a spacecraft to efficiently land on Mars. It’s a nationwide asset. So we are saying, “You’re not being meek,” and but you’re doing all of the checks you possibly can to make sure that it’ll succeed. You can not put the car in danger.
Sam Ransbotham: Mm-hmm. Most people listening clearly should not going to be exploring Mars, however after we take into consideration the analogies you can make, individuals are deciding proper now about danger portfolios, about how a lot they flip over to a machine to, in your case, determine novelty or determine the place to drive. Different individuals are making the identical kind of danger selections. Now, it looks like you could have an especially low tolerance for danger, given the asset and the place it’s. However I really feel like different individuals, with synthetic intelligence and new applied sciences, must be making related danger selections as effectively.
Vandi Verma: I feel you’re completely proper. In actual fact, I’d assume that in some methods, you may assume we’ve a danger tolerance, however we’ve to make these selections so incessantly, we might do nothing and never transfer in any respect if we truly had been very risk-averse. Having a course of to guage it and figuring out, for a specific state of affairs, the place that threshold is, is one thing that everyone on the workforce kind of learns to do with no matter job they’re doing. So I feel it’s truly one thing that will go over effectively into different areas.
Shervin Khodabandeh: Coming again to one thing you mentioned earlier, while you talked about autonomous driving: You actually can’t apply driving in a spot you’ve by no means been earlier than, so how do you apply earlier than you get there?
Vandi Verma: There are two parts to that. One is, how do we’ve the autonomous functionality apply, after which how do we’ve the people, who nonetheless at some stage have to instruct the autonomous functionality, apply? So we do each of these. When it comes to constructing robots for a planetary physique — which is so completely different, proper? The gravity on Mars is completely different, the strain, the temperature, all this stuff — we create simulations. Among the software program that’s working onboard Perseverance, I helped program, and, actually from the start, we develop software program simulations as a result of we could not even have the complete Earth reproduction. We create a full-scale mannequin on Earth to check, however that’s additionally evolving within the early levels of the mission. So we’re constructing {hardware}, which they’re additionally experimenting with — “What’s the perfect wheel design? What’s the perfect materials?” — as we’re writing the software program.
And there’s quite a lot of thought that goes into “How do you construct these simulations so they’re serving to us characterize the setting we’re in appropriately?” However then we additionally begin to peel away sure {hardware} interfaces. So we’ll have the true flight software program working on extra kind of industrial interface robotic components however in our Mars Yard. We’ve a Mars Yard. It isn’t Mars, however we attempt to have slopes and bedrock and different traits. After which we construct the complete reproduction working the precise computing we’re going to have on Mars with the sensors, and we take a look at it. And after that, we do particular checks. So we’ll have a thermal vacuum chamber take a look at for sure components, and we do it in bits and items.
As we’re getting into the ambiance, we do some checks with plane on Earth as a result of we’ve to take a look at how we might land on Mars. However aside from that, as soon as we get on Mars, we do it in levels. So we’d even have the autonomous navigation inform us what it will do however not truly do the navigation.
We might even have the human direct the drive, as we name it, however we’re truly letting it shadow and say, “Let’s see what you’ll have executed.” And so we do it in levels.
We do need to progress in a short time as a result of if you happen to do this for too lengthy … it’s helpful time on Mars. In order that’s kind of how we’ve rolled out the autonomous functionality. Now, by way of people, I’ve been driving robots on Mars for a number of completely different missions since 2008. You begin to get to know Mars, and it takes time. So we’ve been shortening the time. We’ve trainees, we’ve classroom classes, so we take drives from Mars and the info, and we’ve them plan offline. After which we’ve shadows. So many of the drives now, I even have another person I’m coaching on the keyboard, and also you’re kind of watching them as you prepare them to be a pilot. So we do this, and that truly nonetheless takes years.
A few of us who helped construct the robotic will begin on Sol 0, which is the beginning of after we land a mission on Mars. After which, in a short time, inside half a yr to a yr, we begin having the subsequent set of individuals come. As a result of if you happen to take a look at missions, they are often on Mars for a really very long time, so you need to have individuals skilled to do this.
Sam Ransbotham: Really, there’s a number of fascinating elements of that by way of issues that different individuals are doing. However you talked about simulating and constructing digital twins. You don’t need to apply on Mars. You need to apply on Earth, otherwise you apply digitally, particularly, as you talked about — which I hadn’t appreciated — that the {hardware} doesn’t exist to even apply on, even if you happen to may apply; that’s occurring concurrently. But additionally, this concept that people are studying, too, within the course of and that you just wouldn’t flip anybody free driving on the primary day behind the wheel; you wouldn’t flip the rover off to drive by itself the very first day both. In order that strategy of studying is fascinating too.
I additionally thought it was fascinating. … You had been speaking about shortening the time — that as you get extra expertise, you possibly can shorten that point. And as we’ve so many individuals on the earth deploying synthetic intelligence options to do various things, I’m guessing lots of people watch them fairly fastidiously at first however then progressively belief them an increasing number of. And that’s the identical means I’m guessing that you just work with the opposite individual you had been speaking about on the keyboard — in all probability taking a look at them typing the primary day however much less time on the keyboard now. So I feel there’s a number of analogies, regardless that Mars looks like a international setting, to how different individuals are utilizing synthetic intelligence as effectively.
Vandi Verma: Yeah, I feel you’re completely proper. One of many fascinating issues is, what’s it that you would be able to take from a very completely different a part of the planet, a very completely different robotic, that may even have completely different mobility traits? However people are in a position to extract patterns very effectively. So if you happen to had been a rover driver on one rover mission, you truly take much less time, such as you’re saying. But additionally a part of it’s, we’re changing into rather more subtle in our person interfaces.
In case you take a look at the interface we use to function and drive robots — function the robotic arm and really pattern, which is in some methods much more sophisticated — they’ve additionally developed considerably. We used to ship directions — like, actually command-line directions such as you may do with a operate name on a program. Now we do it very graphically, the place you’re primarily kind of choosing waypoints on a map. So I feel that can be extraordinarily useful as a result of we’ve began to let the people concentrate on the facet the place human instinct and the wealth of expertise we accumulate and might carry to an issue. … As a result of AI nonetheless, regardless that it’s getting actually subtle, the capabilities we’ve, they’re nonetheless restricted by our creativeness on the time we created it. We’re very conscious of this from having operated robots for many years on Mars. We all the time inform ourselves, “What’s past our creativeness?” As a result of it occurs — it occurs each single time. We all the time are shocked by these superb issues, and we find yourself utilizing it in a means we hadn’t meant to. And that’s kind of like what you see on a regular basis — the know-how you may develop for varied different Earth purposes. What different issues are individuals going to provide you with and use it for?
Sam Ransbotham: Individuals are loopy.
Vandi Verma: I imply, I feel they’re progressive!
Sam Ransbotham: Proper. And that’s actually what you need, since you’re not simply making an attempt to do the identical factor over and over.
You talked about the phrase shock, which I believed is an fascinating factor. One of many issues that we talked about was that you just do all these simulations and also you need stuff to work, however you don’t need it to work precisely completely since you’re making an attempt to find one thing that you just’re not anticipating. So inform us a little bit bit about how that course of works of “Hey, we would like issues to work like we would like them to work, however we’re additionally open for issues to occur that we weren’t anticipating?”
Vandi Verma: That’s an excellent level you make … that the simulation shouldn’t be going to be precisely how issues execute. And, actually, it virtually by no means is. And partly, the explanation we’re driving autonomously is as a result of the detail-level floor data — the imagery that the rover goes to take from its Mars cameras — we can’t simulate it exactly sufficient. And so any path that we simulate on the bottom, it’s sampling terrain. , we’ve an abstraction; we’ve an orbital map. Nevertheless it’s doing it at a really coarse stage. And if we already had that element map, we wouldn’t even want autonomous navigation. We might actually simply script it to drive.
As quickly because it drives 5 [or] 10 meters, it has way more details about the setting than we had earlier than we despatched this command. So at that time, it’s way more able to making selections and doing the appropriate factor than something we may [do]. So we’ve to study to not over-constrain it. And that is truly one of many issues that’s actually arduous to show new individuals: You’ve perfected it in your simulation, however you need to anticipate the place your simulation is definitely a simulation. It isn’t actuality. And if you happen to don’t depart it sufficient room to maneuver, you’re truly going to have it fail miserably.
So we’ve this stuff we name “maintain in bins” the place, for autonomous functionality, we kind of need people to say, “I’ve some perception, and I need you to remain inside this space.” It may be 100 meters, proper? Like, a extremely massive space. So we create these leashes to leash the habits, however there’s an artwork in how lengthy you make the leash.
Shervin Khodabandeh: Vandi, this has been a extremely fascinating dialogue. Are you able to additionally share a bit about the way you ended up on this function?
Vandi Verma: I keep in mind watching the Mars Exploration Rovers land. I used to be in graduate faculty. I used to be doing my Ph.D. in robotics, truly on the time as a result of I had already taken a category — and it was a programming class the place we had been programming cell robots. And it was simply a lot enjoyable that I feel I spent all my spare time simply on this competitors we had on the finish of the category, the place we needed to have these robots navigate a maze.
And it was simply fascinating to me that you can apply the idea to an precise machine and see it do one thing within the setting. I’d been working with AI, truly; my grasp’s was in AI, and it was fascinating. However right here, there’s one thing so satisfying a couple of robotic that you would be able to truly see working in a bodily world. And I really like area exploration; the mixture of area and robotics was only a excellent match. And the robots ended up lasting so lengthy, the mission for the Mars Exploration Rovers spurred a chance — it was imagined to be 90 days — that I graduated, and it was nonetheless on Mars. So I truly by no means thought that I’d truly get to work on them, and I did.
And so I feel that’s kind of the way it took place is, I used to be fascinated by it, and once I was at college, there are quite a lot of collaborations that NASA does with universities as a result of an enormous a part of the mission is training. And so you will get uncovered to this. You’ll be able to work on issues which can be fascinating to NASA, and my thesis was very a lot aligned with that, and that’s how I acquired into it.
Sam Ransbotham: Very cool. You’ve gotten some engineers to thank for the longevity of the mission that allow you to step in and do it.
We’ve a section the place we need to ask you some rapid-fire questions. Simply reply the very first thing that happens to you as we do that.
What do you see as the most important alternative for synthetic intelligence proper now?
Vandi Verma: I feel the most important alternative … I feel it’s in robotics, truly.
Sam Ransbotham: Shockingly.
Vandi Verma: Sure.
Sam Ransbotham: OK. What’s the most important false impression individuals have about synthetic intelligence?
Vandi Verma: I feel the most important false impression they’ve is that it will possibly’t extrapolate.
Sam Ransbotham: Hmm. So, what was the primary profession that you just wished?
Vandi Verma: I wished to fly airplanes. My dad was a pilot. I wished to be a bush pilot.
Sam Ransbotham: Nicely, since then you could have gotten your pilot license, so that you’ve achieved that.
Vandi Verma: I did, sure.
Sam Ransbotham: Do you assume there are locations that we’re making an attempt too arduous to make synthetic intelligence match an answer that it doesn’t slot in? And are we making use of this device within the incorrect locations wherever?
Vandi Verma: I feel that generally you can have mentioned that about neural networks, at a sure stage. So I’m truly a little bit bit shy to say, is it the incorrect place? It relies on the place your bar is to comprehend whether or not it’s price it to do, given the know-how at this stage. I feel it simply relies on your threshold and your horizon.
Sam Ransbotham: OK, that’s honest. What’s one factor you assume that will be very nice if synthetic intelligence may do proper now that it at the moment is simply not able to? What’s the one factor you can change?
Vandi Verma: , one of many issues is that we do have an enormous, enormous quantity of knowledge. And one of many limitations in making use of it for a number of the area explorations [is], you continue to want quite a lot of auditing of the tokens or what it extracts. So I feel there’s nonetheless simply quite a lot of tweaking. That’s the problem with it, I feel. In case you may recover from that, I feel that potential could be unleashed.
Sam Ransbotham: Nice dialogue. I’m guessing that, in fact, none of our listeners are driving robots on Mars, however I feel there’s a number of issues that folks can study from the issues that you’ve got discovered by means of this course of. Folks is probably not constructing digital twins for simulating Mars, however they’re constructing digital twins for simulating processes on Earth. We’re all more and more experiencing the world by means of these units and thru AI sensing. Even when we don’t work within the area context, I feel we will study lots from what you and your workforce have discovered. Thanks for taking the time to speak with us at this time.
Vandi Verma: Thanks a lot for sharing a little bit little bit of what we do together with your viewers.
Shervin Khodabadenh: Thanks for listening. Be part of us subsequent time when Sam and I meet Prem Natarajan, chief scientist and head of enterprise AI at Capital One. Please be part of us within the new yr.
Allison Ryder: Thanks for listening to Me, Myself, and AI. We imagine, such as you, that the dialog about AI implementation doesn’t begin and cease with this podcast. That’s why we’ve created a bunch on LinkedIn particularly for listeners such as you. It’s known as AI for Leaders, and if you happen to be part of us, you possibly can chat with present creators and hosts, ask your personal questions, share your insights, and acquire entry to helpful sources about AI implementation from MIT SMR and BCG. You’ll be able to entry it by visiting mitsmr.com/AIforLeaders. We’ll put that hyperlink within the present notes, and we hope to see you there.
