Tianyu Liu, Fu Zhang, Fei Gao, Jia Pan
This research introduces a motion planning framework for Unmanned Aerial Vehicles (UAVs) that accurately estimates collision probability in environments with dynamic obstacles and external disturbances. By providing tighter bounds on collision risk, the framework enables less conservative and more efficient trajectories, demonstrating high success rates of up to 99% and reduced mission completion times in complex simulations and real-world experiments.
Key insights
- Accurately estimating collision probability with a tighter upper bound significantly reduces planning conservatism, allowing for more aggressive yet probabilistically safe UAV trajectories.
- A comprehensive approach to uncertainty management requires integrating probabilistic modeling for dynamic obstacles with forward reachable sets for external disturbances.
- An iterative optimization strategy, which alternates between efficient approximated probability for initial steps and precise exact probability for refinement, effectively balances computational feasibility with accuracy requirements.
