Detailed Description
Penalize trajectories with rotational velocities.
This class provides a cost based on how much a robot "twirls" on its way to the goal. With differential-drive robots, there isn't a choice, but with holonomic or near-holonomic robots, sometimes a robot spins more than you'd like on its way to a goal. This class provides a way to assign a penalty purely to rotational velocities.

Return a raw score for the given trajectory.
scores < 0 are considered invalid/errors, such as collisions This is the raw score in that the scale should not be applied to it.
Implements dwb_core::TrajectoryCritic.
