is like the very first thing that somebody did with VR was build a simulator of an office which is like I think the entire promise and failure of the technopian movementin one idea. Yeah, we've built this incredible technology where you can live inside the computer and it looks like your office, you know. Um, but uh in
There also could be use cases outside of crisis that we haven't even really thought of yet. simulator to help identify areas that are still supportive of conversion therapy, helping to inform where we might kind
It's going to be a strange world if people spend too much time in VR. Simulator sickness-- we all work hard to make sure that our technology has got high frame rates, low update rates.We try not to move the camera.
And interestingly enough also in this context the very first digital computer with magnetic stored memory, the World Wind computer, was itself originally designed to be a flight simulator to allow the Air Force to test out aircraft before they had been actually designed.This project grew far outside of this origins to become for a stored program computer that
And so we've actually been having conversations with the .org team recently about how we might be able to, for example, share what we've built with the crisis contact simulator . We know that that could be really helpful for other crisis organizations in training development. There also could be use cases outside of crisis that we haven't even really thought of yet.
And here are different aspects of Astrobee. The simulator , now released on GitHub-- I would encourage you guys to check it out.
But in fact, it's just failed to save either. fidelity simulator . And taking into account all of those probabilistic, noisy
And I'm an astrophysicist, although these days I actually work in the video game industry as an astrophysics engineer for Universe Sandbox, which is this beautiful astrophysics simulator that you should all go check out on Steam. But for the past several years, I've also been getting deep into the world of space ethics, in particular the ethics of space settlement.
So the thing that initiates an add, the thing that starts a multiply, it's always going to be synchronized with that central program and pulse. So in the simulator , basically what I've got is a set of channels that go directly from the cycling unit, the clock generator, to each of the units in the machine that consumes clock.
And just like VR comes from the flight simulator , in interviews, we also make mistakes. We have a flight simulator because mistakes are very expensive in a plane, but they're not expensive when you're simulating we should learn by doing. And we've been working with the NFL to help their personnel become better at giving interviews and become less biased.
It was called, "Is the Universe a Computer?" And the idea there was not so much Elon Musk's idea, which is that we're all living inside a simulation, which is one type of simulator inquiry, but the other idea was, is the universe fundamentally computable? Like everything we see, is it a consequence of computation?
And here are different aspects of Astrobee. We do have a simulator that's now released in open source that has a lot of the flight software involved.
So this is where I come in, actually, in our team in India, where we do it. It's like a simulator old style ballot box with a slit.
a model of the robot, and a model of the world, which includes others in the world. So this is the simulator . This is a more or less a regular robot simulator .
So we started by building up a simulator . Not a flying simulator , but a tool which simulates 24 hours flight of such an airplane. So how much you collect, how much you use, the aerodynamics of heat-- all the flying characteristics.
larger and massively more complicated simulation devices. I don't know if you can see but that's a little model of the, well full scale model, of the Apollo command module here with these vast architectures of simulator lenses around it. The glass in this simulator alone weighed more than the actual Apollo capsule. In fact highly sophisticated techniques of projection were deployed to give a pseudo-three dimensional aspect to the pictures outside the window. When you moved your head the pictures
But, no, listen, we have full access-- I mean, anyone seen the show-- to the track, and we're in there with the drivers So in our simulators , it's part of our world.
in bad weather. The first simulator company, The Link Company, was an organ company not coincidentally because all these simulators used pneumatic tubes to provide a kind of analog computing model of simulation. And interestingly enough also in this context the very first digital computer with magnetic stored memory, the World Wind computer, was itself originally designed to be a flight
And we feel like the partnership set us up to continue to innovate with our own technology team long after Googlers left the organization. And beyond the crisis contact simulator , we're also starting to think of a lot of other really important and impactful areas that we can innovate in technology.
But others have suggested that maybe there is an evolutionary basis of this, in the sense that, by telling stories to each other, we kind of fire up a flight simulator of engagement with the world, where we are able to have a whole variety of experiences that are safe but allow us to imagine how we might respond if we encountered those kinds of experiences in the real world.
So my thesis was called "A Performance Study of the Acorn RISC Machine." And I wrote a C Compi-- sorry, I wrote a C Compiler. I wrote a instruction set simulator called ARMulator. I put MIP style floating point on the side of it.
having finished what they were doing with that first pulse. So here is an image of the simulator .
That's an admirable trait. I play this very intricate flight simulator called, "DCS"-- "Digital Combat Simulator "-- where you don't press a button to start up a jet,
But what we've done here is we've actually put an off the shelf simulator inside the robot and made it work in real time. So the output of the simulator for each of those next possible actions is evaluated and then goes through a logic layer. Which is essentially the rule, the if then else rule that I showed you a couple of slides ago.
But in fact, it's just failed to save either. And also strategies for choosing which fidelity simulator to use at a particular time.
This is a street vendor simulator , but it could just as well be seen as a game about poverty in contemporary America.
You have to build a simulator into your tool that explores different kinds of mitigating options,
Of course, then it narrowed a little bit because we had to make a design freeze. So we started by building up a simulator . Not a flying simulator , but a tool which simulates 24 hours flight of such an airplane.
Because actually I was a simulator , a simulated personality.
So we have built some simulators , simulating indoor environments that gave us perfect ground truth.
This is a more or less a regular robot simulator . So you probably know that robot simulators are quite commonplace. We roboticists use them all the time to test robots in, as it were, in the virtual world, before then trying out the code for real.
is what I call sensory and reality simulators .
Even these guys that still give simulators to the pilots just to make sure that they can collect proper information, which proves that you still need somebody to
them out with uh biological simulators uh all of these different aspects of U health and Medicine
- This is the most simple version of a sandpile simulator that you could almost imagine.
training, simulator trainings, and line trainings, blah, blah, blah.
Unlike, in the simulator , if something goes wrong, you hit Pause, and you get out, and then you go to lunch.
And later I modeled a 16-bit ARM. And this comes in later as a replacement for the teaching simulator . A couple of days after handing in my thesis I saw my first copy of Patterson and Hennessy's "Computer Architecture-- A Quantitative Approach."
But on the 3rd of May I heard from somebody called Lee Smith at advancedRISCMachines.co.uk. So day one was write an instruction set simulator .
So the fact that these configurations aren't fixed, that the programmer can choose whatever they want for the configuration, means I've got to have a fairly general mechanism in the simulator to allow you to sort of connect as many transmitters and receivers as you want to one of these buses.
having finished what they were doing with that first pulse. So that ends up actually throttling the speed of the simulator a bit.
having finished what they were doing with that first pulse. And some people are a little surprised to find that the simulator actually runs slightly slower than the original machine.
Why did you look in this place? And just like VR comes from the flight simulator , in interviews, we also make mistakes. We have a flight simulator because mistakes are very expensive in a plane, but they're not expensive when you're simulating we should learn by doing.
And here are different aspects of Astrobee. Here's some architecture talking about what the simulator does, simulating a lot of fact on first stack built into the Astrobee unit.
okay we trained for the space flight we had our own simulator and it was a very rudimentary simulator and you spent I
So this is the simulator . This is a more or less a regular robot simulator . So you probably know that robot simulators are quite commonplace.
So this is the simulation budget. So we're actually using the open source simulator Stage, a well-known simulator . And in fact, we managed to get Stage to run about 600 times real time.
And no one could land this airplane. And Andre's spent already 72 hours in the flight simulator last year in order to train all these, the sleep cycles, he was monitored completely with
war game "Conflict," Milton Bradley's Cold War simulator "Summit," and a French game known in the US as "Risk."
In some patients who got a deep brain simulator who had previously untreatable depression, that wouldn't respond to any drugs, they suddenly had normal mood.
