RCF-RRT*: A risk-clearance cost-field-guided RRT*-based planner for global USV path planning in static risk-constrained maritime environments

Path planning for unmanned surface vehicles (USVs) in risk-constrained maritime environments requires the simultaneous consideration of obstacle avoidance, environmental risk, safety clearance, and trajectory executability. Existing sampling-based planners can efficiently explore feasible regions; however, their expans...
