I wrote quite a bit about Velodyne in The Laser That’s Changing the World — David Hall, the company’s founder and CEO, is a brilliant engineer who developed the lidar sensor that paved they way for the first great leaps in vehicle autonomy, which manifest in the 2007 DARPA Urban Challenge. The company still sells the HDL-64E, which is much the same as the lidar unit that helped serve as the “eyes” on Carnegie Mellon’s winning “Boss” entry and other competitors 12 years ago. An entire industry has since developed around lidar for autonomous vehicles; Velodyne remains the leader.
Some time back, I did a Q&A with the folks there — you’ll find it here.
