Divi, Pieter H. van … WebIn this module, we'll discuss the lowest level of our hierarchical motion planner, which is the local planner. As a reminder, the local planner is the portion of the hierarchical planner that executes the maneuver requested by the behavior planner in a collision-free, efficient, and comfortable manner. This results in either a trajectory, which ...
