Get the period at which the local planner is expected to run. Alonzo Kelly. Along the way, the planner creates, at least locally around the robot, a value function, represented as a grid map. Odometry information that gives the local planner the current speed of the robot.

How long before hitting something we're going to enforce that the robot stop. The basic idea of the Dynamic Window Approach (DWA) algorithm is as follows: D. Fox, W. Burgard, and S. Thrun. This value function encodes the costs of traversing through the grid cells.
