High School Student Slashes Cost of Driverless Cars

Ionut Budisteanu, a high-school student from Romania, has invented a system that slashes the price tag of driverless cars:

“The most expensive thing from the Google self-driving car is the high resolution 3-D radar, so I was thinking how I could remove it,” he told NBC News. His solution relies on processing webcam imagery with artificial intelligence technology to pick out the curbs, lane markers, and even soccer balls that roll onto the road. This is coupled with data from a low-resolution 3-D radar that recognizes “big” objects such as other cars, houses, and trees.

All of this information is collected and processed real time by a suite of computers that, in turn, feed into a “supervisor” computer program that calculates the car’s path and drives it down the road….The high-resolution 3-D radar used by Google, he noted, costs about $75,000. His whole system should work for no more $4,000.

Actually, it’s not the cost savings that are interesting here. Google’s engineers are undoubtedly well aware of cheaper alternatives to their high-res radar, but have stuck with their current system because it provides better feedback and price is no object when you’re still in the prototype stage. What’s interesting is the fact that Budisteanu’s system essentially replaces Google’s expensive hardware with cheap processing power. This is one of the keys to the future of artificial intelligence. As recently as a few years ago, Budisteanu couldn’t have done what he did because the processors then available wouldn’t have been powerful enough. Today they are, which means that brute force plus some software can do the same thing as Google’s sophisticated radar.

Brute force isn’t the answer to all AI problems, but lots of processing power is a minimum necessary component. Without it, you simply have no chance of coming close: a hamster-sized brain can’t solve differential equations no matter what you feed it. But once you get a bigger, faster brain, possibilities start to open up that seemed impossible only a short time before. Budisteanu’s invention is a pretty good example of this.

WE'LL BE BLUNT:

We need to start raising significantly more in donations from our online community of readers, especially from those who read Mother Jones regularly but have never decided to pitch in because you figured others always will. We also need long-time and new donors, everyone, to keep showing up for us.

In "It's Not a Crisis. This Is the New Normal," we explain, as matter-of-factly as we can, what exactly our finances look like, how brutal it is to sustain quality journalism right now, what makes Mother Jones different than most of the news out there, and why support from readers is the only thing that keeps us going. Despite the challenges, we're optimistic we can increase the share of online readers who decide to donate—starting with hitting an ambitious $300,000 goal in just three weeks to make sure we can finish our fiscal year break-even in the coming months.

Please learn more about how Mother Jones works and our 47-year history of doing nonprofit journalism that you don't find elsewhere—and help us do it with a donation if you can. We've already cut expenses and hitting our online goal is critical right now.
