MIT built a self-driving car that can navigate unmapped country roads
This is big. The need for super detailed maps is one of the big drawbacks of self-driving cars right now. "Taking the road less traveled is extremely difficult for self-driving cars. Autonomous vehicles rely on highly visible lane markings, as well as detailed 3D maps in order to navigate their environment safely. Which is why most of the major companies have eschewed testing on unmapped rural roads in favor of suburbs and cities. Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a new system that allows self-driving cars to drive on roads they’ve never been on before without 3D maps. Called MapLite, the system combines simple GPS data that you’d find on Google Maps with a series of sensors that observe the road conditions. This allowed the team to autonomously drive on multiple unpaved country roads in Devens, Massachusetts, and reliably detect the road more than 100 feet in advance. (As part of a collaboration with the Toyota Research Institute, researchers used a Toyota Prius that they outfitted with a range of LIDAR and IMU sensors.)"
