Hi, I'm trying to use ur_robot_driver to control a UR5 robot via ros. I followed the instruction on https://github.com/UniversalRobots/Un... to setup my robot.

After running the ur_robot_driver bring up launch file on PC, I started external_control program on tablet, and got this time out error(even I can ping arm IP from PC): image description.

My setting: Ubuntu18.04, ROS Melodic, ur_robot_driver. Arm IP: 192.168.131.40 PC IP: 192.168.131.1

Network setting in ur tablet: image description image description

I'm sorry to have to do this for something seemingly minor, but please don't post screenshots of terminal text in question on ROS Answers. It's all text, so there is no need. Just copy-paste the text from the terminal into your question text. Do make sure to format it properly by selecting the text and pressing ctrl+k (or clicking the Preformatted Text button (the one with 101010 on it)).

You don't need to post a new question, just edit your curent one. You can use the edit button/link for this.

After you replace the screenshot with the error message itself, we can re-open your question.

Having written that: in many cases there is a firewall on the ROS PC which is blocking the connection. Either configure it to allow traffic on the used TCP ports or disable it completely.
