OctoMap

OctoMap is a system used by robots to create and understand 3D maps of their environment. It organizes space into tiny cubes called "voxels," each representing whether that area is free, occupied, or unknown. Using sensors like cameras or lidars, the robot gathers data and updates the map in real-time. This helps robots navigate safely, avoid obstacles, and plan paths efficiently. OctoMap's structure allows for scalable, detailed, and flexible mapping, making it a powerful tool for autonomous systems working in complex, three-dimensional spaces.
