A little uncertainty can help drones dodge obstacles at high speeds, says MIT

For drones trying to navigate a busy environment like a warehouse or a forest at high speed, the ability to know exactly where they are at all times would seem pretty essential. Not so, say researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), who have a devised a new, efficient way to guide drones around obstacles. The key ingredient? Uncertainty.With most drones — and, indeed, most self-driving vehicles — navigation starts with a map. To dra
