The assisted_teleop node subscribes to a desired trajectory topic (geometry_msgs/Twist) and uses TrajectoryPlannerROS to find a valid trajectory close to the desired trajectory before republishing. Useful for filtering teleop commands while avoiding obstacles. This package also contains LaserScanMaxRangeFilter, which is a LaserScan filter plugin that takes max range values in a scan and turns them into valid values that are slightly less than max range.
