SANDO değişen ortamlarda dronlar için güvenli uçuş rotaları planlıyor

MIT researchers have developed SANDO, a trajectory-planning system for uncrewed aerial vehicles operating in unmapped places with moving obstacles. Existing planners can often provide formal safety guarantees only when obstacles are known beforehand or remain still. SANDO instead needs to know the maximum speed an obstacle can reach. It uses that limit to calculate the greatest distance the object could travel within a given period and surrounds it with a protective sphere. The system then builds a time-sensitive corridor through safe regions of three-dimensional space. A heat map guides the vehicle away from crowded areas, while onboard optimisation selects a fast route inside the corridor. As the drone moves and new sensor data arrive, SANDO updates both the corridor and the trajectory. In simulations, it reached its goals faster than several leading systems without collisions. A real drone also avoided every dynamic obstacle in twelve test flights, suggesting potential uses in disaster response, mine exploration and delivery.
