Algorithm prevents drone collisions in midair.

MIT researchers have developed a new algorithm called Robust MADER that generates collision-free trajectories for drones even when communications between agents are delayed. The multiagent trajectory-planner enables a group of drones to formulate optimal, collision-free trajectories. The algorithm incorporates a delay-check step during which a drone waits a specific amount of time before it commits to a new, optimized trajectory. When tested in simulations and flight experiments with real drones, Robust MADER achieved a 100 percent success rate at generating collision-free trajectories.
