Remember 5 years ago when a bunch of robotic cars managed to navigate through the desert all by themselves? And remember 3 years ago when a bunch of robotic cars managed to navigate through a (fake) urban area all by themselves? Well, today it’s the future, and autonomous robotic cars from Google have already logged 140,000 miles on busy, complex city streets and highways with only occasional human intervention, and 1,000 miles without any human control whatsoever. Writing about this kind of thing makes me all tingly, because ever since I saw that autonomous Passat park itself at Stanford a year ago, it’s become clear that robotic cars aren’t some far-off futuristic dream, but that this technology is actually achievable in the near term. I mean, consider how much time you spend in your car effectively doing nothing, and then think about how much things would change if you could be productive (or asleep) instead. And of course, it’s not just that: autonomous cars have the potential to reduce traffic by driving closer together, drastically improve gas mileage with cooperative drafting, and (most importantly) significantly reduce the number of car accidents, which cause 1.2 million fatalities worldwide and exponentially more injuries plus untold emotional (and financial) trauma. Lots more, after the jump. On to the cars themselves. Besides the big honkin’ LIDAR system mounted on the roof, the rest of the equipment is fairly low-key… There’s a position sensor mounted on the wheels, some small radar sensors in the bumpers, and a video camera in front of the rear view mirror to detect stop lights, stop signs, pedestrians, and bicyclists. The real trick, though, seems to be that Google sends out manned scout cars ahead of the autonomous ones to map the route (lane markers, etc.) in detail. You might […]
