youbot在ROS中启动youbot_driver_ros_interface中遇到下面的报错：

我在网上也搜很久，官网上的办法也不能解决我这个问题，youbot官网http://www.youbot-store.com/wiki/index.php/The_youBot_base_motor_controller_have_to_be_of_type:_174_or_1632
我也不停的更换youbot_driver和youbot_driver_ros_interface，但是都不能解决，这个问题我连续搞了好几天，突然有一天，我无聊的去交换一下youbot机械臂下面的ethcat接口，TMD，居然驱动启动正常了，之前我把链接电脑的网线插在机械臂下面的ethercat2上就报上面的错，后来我把它插回ethercat1那个孔，把底座链接机械臂的网线插在ethercat2就OK了。
