LIDAR, which stands for "light detection and ranging," is a method that many robotic systems use as a form of sight and the new LIDAR sensor developed by scientists at MIT and DARPA has the potential to open the eyes of roboticists everywhere. Produced on 300 millimeter wafers for a cost of approximately 10 dollars each, the new LIDAR sensor is significantly smaller and cheaper than the competition.

LIDAR is a high-tech system that treats light in the way that radar treats radio waves. Due to its complexity, previous LIDAR sensors have been both large and expensive, with commercially available systems running up to the price of a high-end car. The new LIDAR sensor from MIT and DARPA not only solves these size and price problems, but is also more robust, with beam steering that's 1,000 times faster than other systems.
