For robots to operate in the physical world they need a decent pair of eyes. Usually, this is job is taken care of using LIDAR — a technology that bounces light off nearby surfaces to create a 3D map of the world around it. LIDAR is just like radar in its basic mechanics, but because it uses light, not radio waves, it's much more accurate; able to pick out individual leaves on a tree when mounted on a plane, or track the movements of cyclists and pedestrians when fitted to a self-driving cars.
However, LIDAR systems are also bulky and expensive. High-end models costs tens of thousands of dollars, and even the smallest new systems are the size of a hockey-puck. Here's what a LIDAR sensor normally looks like, mounted on top of one of...
