Adventures in Science: LIDAR

LIDAR, which is either a mashup of “laser” and “radar” or an acronym for “light detection and ranging” (depending on whom you ask), is the method of shooting a laser at an object and measuring the time it takes for that reflection to return to a receiver. With it, we can measure distances, determine the speed of moving cars, and map terrain. Here, we look at how LIDAR works and how it can be applied to robots to give them a means to detect objects.
