Class Documentation

class BaseObstacleCritic : public dwb_core::TrajectoryCritic
Uses costmap 2d to assign negative costs if a circular robot would collide at any point of the trajectory.
This class can only be used to figure out if a circular robot is in collision. If the cell corresponding with any of the poses in the Trajectory is an obstacle, inscribed obstacle or unknown, it will return a negative cost. Otherwise it will return either the final pose’s cost, or the sum of all poses, depending on the sum_scores parameter.
Other classes (like ObstacleFootprintCritic) can do more advanced checking for collisions.
