This Palm-Sized Laser Could Make Self-Driving Cars Way Cheaper

We don’t know how much self-driving cars will cost when they finally hit the market, but our best guess is, a lot. The technology needed to take the wheel out of your hands is frightfully expensive. Now, we can revise that estimate down a bit with the debut of a laser system that’s roughly the size and shape of a hockey puck and costs just eight grand.

Silicon Valley-based Velodyne Acoustics makes sound systems and a self-stabilizing boat said to prevent seasickness, but its most high profile product is the Lidar (Light Detection and Ranging) system spinning proudly atop each of Google’s self-driving cars. The device uses 64 lasers to map the physical the world. It can collect more than a million data points about its surroundings every second, crucial information for autonomous automobiles. It’s remarkably cool, and remarkably expensive: Each unit costs up to $85,000, far too pricey to be used in vehicles the rest of us might one day buy.

Which brings us to the Puck, Velodyne’s miniaturized version of that technology. Instead of 64 lasers, it has just 16, resulting in a tenfold reduction in price. It’s also smaller, just 4 inches tall and 1.3 pounds—compared to 10 inches tall and 29 pounds for the unit on each of Google’s robocars. At $7,999, it’s small and cheap enough for mass-market vehicles, a big help for automakers intent on offering cars that drive themselves in the next decade.
