Statements from this episode (15)
Boots: Computational AI tools will help decipher the human nervous system
“Ultimately I believe that
these sorts of tools, these mathematical tools and computational tools will allow us to understand the nervous system better rather than kind of thinking about it the other way around.”
Lonsdale: David Hume inspired many of the ideas for Palantir
“I've actually also been obsessed with Hume. He's inspired a lot of the ideas for Palantir.”
Boots: Team is the sole remaining group in DARPA RACER program
“There were several teams to start and then there are several phases in the program and at each phase there's a down select. So we're still involved in the program and no one else is.”
Boots: 2001 NDAA targeted one-third autonomous US military ground vehicles by 2015
“So actually back in 2001 in NDAA there was the idea that one third of ground vehicles in the US military were going to be autonomous by the year of 2015.”
Boots: Off-road autonomy solves terrain traversability, while on-road solves agent intent
“The major challenge there is not, you know, how do you actually traverse terrain? I mean, you're driving on roads which are engineered to be a very easy to drive on. The challenge is dealing with all of the different agents that are in the environment. So thin…”
Boots: Overland AI vehicles navigate using either cameras or LiDAR alone
“We can use either LiDAR or camera alone. So you can use either one. Using both together allows you to get a more accurate picture of the terrain around, around the vehicle.”
Boots: LiDAR emission makes vehicles easily detectable to equipped adversaries
“LiDAR, Projects projects into the environment. And so you can see it you know, very easily if you have the right sort of sensors.”
Boots: Most uncrewed ground vehicles in Ukraine are teleoperated
“So, so most of the use of uncrewed ground vehicles in places like Ukraine or like tele operated vehicles.”
Boots: Overland AI builds autonomous vehicles for combat breaching operations
“So we're working with the combat engineers to provide them with tools, basically autonomous vehicles, which allow them to execute portions of that operation without putting a human in harm's way.”
Boots: Overland AI autonomous vehicles reach 35 mph across off-road terrain
“We've actually gone up to about 35 miles an hour on a pretty wide variety of terrain. So this includes off-road terrain. So pure cross country where there's, you know, no roads at all, but we also go through double track and dirt roads.”
Boots: Simulation is insufficient for field robotics without direct terrain testing
“People who are just kind of starting work in robotics often think that you can just do things in, in simulation. But they quickly learned that it is really important to actually run your software on the robot. And then especially in field robotics, run that ro…”
Boots: Autonomy is the essential enabler for military drone swarm command
“We believe that autonomy is actually the key enabler of this. So if you imagine that you want to control 10 assets or a hundred assets that means that you need something to automate some of those assets functionality. Otherwise, you know, you won't be able to …”
Boots: Autonomous ground vehicle hardware should be defined by payload weight
“You can kind of imagine that maybe the payload should define the vehicle. So if you have a lighter payload, you can, you know, have a lighter, cheaper, more tradable vehicle. Whereas if you have a heavier payload, you might need like a larger, more survivable …”
Boots: Overland AI announces Overwatch to command multiple autonomous battlefield robots
“We've just announced Overwatch, which allows for command and control of multiple assets. So we're going to start to be showing that a lot more being able to coordinate multiple robots multiple autonomous robots in a variety of difficult terrain.”
Boots: Overland AI is bringing off-road autonomous vehicle production in-house
“And we're also starting to wade into hardware. So over the last several years, we've learned quite a bit about how to build and maintain Vehicles, which can move very fast through very difficult terrain. And so we're bringing some of that production in house a…”
