safe autonomous trajectory planning for dynamic unknown environments

SANDO introduces a trajectory planner for 3D navigation in dynamic, unknown environments. It addresses collision avoidance with unpredictably moving obstacles through spatiotemporal safe flight corridors (STSFCs) that adapt to obstacle motion over time, a heat map-based global planner using soft costs, and a variable elimination technique for fast MIQP optimization.
