Hi! I looked through the industrialrobotclient/genericimplementation page (here's the link http://wiki.ros.org/industrialrobotclient/genericimplementation)and have confusion. There is a Note in this page: NOTE: The ROS-Industrial specification does allow for a low level streaming interface (sending individual points to the robot, different than the streaming interface below). This is not supported currently by the generic clients. I don't understand the difference between these two streaming interface. Who can give me some explanation? Thanks！
