Teardrop Risk Field-Based Spatiotemporal Path Planning Method for Mobile Robots in Dynamic Environments
Li Y, Guodong Xu, Xi Zhang, Yue Wang, Deqi Zuo
Navigating dynamic environments requires autonomous robots to balance computational efficiency with safety. Traditional isotropic risk fields ignore obstacle velocities, causing overly conservative lateral avoidance or insufficient margins against head-on collisions. To address t…
