Alessio Fanelli: preference

Transcript context

…Yeah. So we don’t make sensors. Like, we’re, we’re not a manufacturer. Obviously, we use a lot of sensors in our autonomy products. in terms of what actually goes on the vehicles, we have a preferred set of sensors that we, let’s say fully support, and then our customers, they can sort of choose from those. And obviously if there’s a very strong opinion on supporting something else, we’ll add that to the platform as well. And the lidar question is at this point sort of the age-old, topic in autonomy, and the state of the industry right now is lidar is hands down a useful sensor, specifically for data collection and the R&D phase of autonomy development. if you see, for example, a Tesla R&D vehicle, it actually has lidar on it to this day, right? In the Bay Area we see these. you’ll see, like, Model Ys or Cybercab that have lidars on them just driving around. So it’s, it’s useful because it gives you per pixel depth information. So if you can pair a lidar with a camerand you can say that, well, this camera’s looking this direction, this lidar’s looking this direction, and now for each pixel of the camera I can see how far away is that pixel. you can actually then use that as a part of your model training, and then the that depth information then becomes a learned, a learned state of the camera data. And then when you’re doing the production system, you can now remove the lidar and now you can actually get depth with just the camera. And so that difference between, like, a highly sensored R&D vehicle and then the down-costed production vehicle, we use that across our whole portfolio of products. And of course the end goal is you want super low cost and super reliable. And then in certain use cases you have some more, bespoke things. Like in defense as an example, you do things at night oftentimes, and so you care about sensors like infrared, more so than And you don’t, you don’t wanna be putting energy out, so you don’t wanna use lidar or radar. but you still need to be able to see at nighttime. So yeah, we work the whole gamut. Cool. So that’s kinda like on the hardware level. Then on the OS level, how does that look like? What is, like, unique? my drive- I drive a Tesla. Whenever I drive some other car that has a screen, it always sucks. It’s on, like, cheap Android tablet. It’s like, it’s laggy and all of that. What does the OS of, like, the autonomy future look like? When most people, it’s really what you just described. When you think about operating system in a vehicle, you’re thinking about the HMI, right? The human machine interface, and absolutely that’s a an important part of it, but that’s actually only one thin layer on top. So when we talk about operating systems for, like, AI in vehicles, there’s many layers that go deep into the CPU critical realm and embedded systems, and you’re talking about the real time control of let’s say the electric motors or the engine and the actuators, and you have different redundancies for different, let’s say, the steering actuation in the vehicle. And all of these things, need very core support in the in the operating system. And then of course for autonomy you have real time sensor data that’s streaming in, and the latencies there are really important, right? If you try to Imagine you try to run Microsoft Windows like streaming your sensor data in or controlling the vehicle. Like, the latencies are gonna be absurd. Like, you can never do that. And so what’s special about what we do is we really have this system level thinking, right? So we’re looking at, we care about every performance characteristics of the entire system, and then we also, because we’re doing a lot of the software or all of that software, we can fine-tune and control all of those things. So we can very carefully tune in the latencies for every aspect of the system. We can carefully tune in the memory management. We can have the right, fail-safes and fallbacks, for different things. ‘Cause you have to account for what if, what if there is a critical failure? What if there’s a cosmic ray that flips a bit in the middle of the processor that causes some, malfunction? And you have to have a fail-safe to all of that, and so the core operating system is a part of that. And then the one last thing, which is a lot less exciting but is, actually a very big topic, is reliability of updates. so the I have a Tesla and you get updates fairly frequently, right? Once a month. Most companies that are making vehicles are basically never doing updates, and they’re And even if they are doing updates, they’re usually only updating maybe one module. Maybe they’re updating the HMI module. But they’re not able to update, let’s say, the CPU critical parts of the system. You have to go into the dealer for that. And so with our operating system now we can actually enable highly reliable updates of any system in the vehicle, and that’s way easier said than done. Like, there’s lots of technical, technically deep stuff, in the tech stack to do that in a way that you’re not going to accidentally brick a vehicle. And right? If, imagine your…
