+# raw_vehicle_cmd_converter
+
+`raw_vehicle_command_converter` is a node that converts desired acceleration and velocity to mechanical input by using feed forward + feed back control (optional).
+
+## Input topics
+
+| Name                  | Type                                                     | Description                                                                                                        |
