from i18n_msgs.action import SetLocale

class SetLocaleActionClient(Node):

    def __init__(self):
        super().__init__('chatbot_set_locale_client')
        self._action_client = ActionClient(self, SetLocale, '/chatbot/set_locale')

    def send_goal(self, a, b):
        goal_msg = SetLocale.Goal()
