terminate called after throwing an instance of 'ros::TimeNotInitializedException'
  what():  Cannot use ros::Time::now() before the first NodeHandle has been created or ros::start() has been called.  If this is a standalone app or test that just uses ros::Time and does not communicate over ROS, you may also call ros::Time::init()

原因:nodehandleをclass内に定義していた
対策:nodehandleをメインですぐに生成し,classに入れて使う.
