Navigation stack velocity setpoint
Reading through the document of the ROS Local Planner, a common one being DWA (http://wiki.ros.org/base_local_planner), It seems like they all provide a setpoint velocity which is then provided to the robot base driver.
Am I correct in my understanding that all of these assume that the robot can accelerate near instantaneously to the set velocity, as none of them seem to take into account that it takes some amount of time to reach a setpoint.
