I finally got the right understanding of the ssh commands into the Turtlebot. I’ve verified ROS_HOSTNAME and ROS_MASTER (first two lines of terminal sign-on are echos of values) which appears to work. I can “list” and “diagnostics” on my workstation, but not on the Turtlebot. Also, although I can usually get dashboard up, it doesn’t “connect” and control anything. <u></u><u></u></span></p>
