  1. I am not too sure what the problem was, however, I connected the robot via router connection (as I previously had it as a direct connection) and enabled auto ethernet (in Unbuntu) and the examples seem to work now.
  2. A new issue has risen. The issue is running the example programs, as none of the example programs work even after using the "enable" command. $ rosrun intera_interface enable_robot.py -e For example the " rosrun intera_examples joint_torque_springs.py " example does not move the robot to a "neutral pose" or even the " rosrun intera_examples camera_display.py " the terminal returns with splay.py Initializing node...

[ERROR] [WallTime: 1484625640.310784] Failed to stop right_hand_camera from streaming on this robot. Unable to start streaming from head_camera [INFO] [WallTime: 1484625640.319965] Camera_display node running. Ctrl-c to quit I am able to get the joint states but none of the example code work. Do you know why this happening?

    Unable to ping to ROS Master

    Hi Ian, A workaround has been found, which is partly the solutiuon you said and opting to use a direct connection to the controller via ethernet cable. However, a new issue has risen. The issue is running the example programs, as none of the example programs work. For example the " rosrun intera_examples joint_torque_springs.py " example does not move the robot to a "neutral pose" or even the " rosrun intera_examples camera_display.py " the terminal returns with splay.py Initializing node... [WARN] [WallTime: 1484625635.265185] Timed out waiting for command acknowlegment... [WARN] [WallTime: 1484625640.309822] Timed out waiting for node interface valid... [ERROR] [WallTime: 1484625640.310784] Failed to stop right_hand_camera from streaming on this robot. Unable to start streaming from head_camera [INFO] [WallTime: 1484625640.319965] Camera_display node running. Ctrl-c to quit Overall, none of the examples work. Do you know why this happening?

    Unable to ping to ROS Master

    Hi Ian, Thank you for the reply. That is what we thought yesterday too, however, as it can be seen on the tutorial/ walkthrough, they specify to use the S/N on the robot (which is a mistake, as you have pointed out) http://sdk.rethinkrobotics.com/intera/Serial_Number We will use the controller's S/N today and update on any news.

    Unable to ping to ROS Master

    We are following the installation tutorial and are currently on the "Hello Robot." The problem we are facing is verifying our connection to the ROS Master. In the tutorial, it states that the ROS Master is the serial number on the baxter arm. When we attempt to ping to the ROS Master URI (serial number), we get unknown host. ________________________________________________________________________________________________ I.e. [intera - http://021xxxRPxxxxx.local:11311] user@ubuntu:~/ros_ws$ ping 021xxxRPxxxxx.local ping: unknown host 021xxxRPxxxxx.local _______________________________________________________________________________________________ Also we have successfully pinged to the controller with its serial number/IP address. Are we suppose to ping to the controller with its serial number or the arm itself?
