Create3 control through the web

[jdbrubaker]

Hi, I would like to undock, dock, and control the robot through a web interface. I have tried calling a PHP file on my web server -shell_exec('undock.sh). My undock.sh script calls the ros2 undock action. This works fine when undock.sh is run fro the terminal, but does nothing through php. Is there any solution? thanks ---john.

This doesn't seem to be a problem with the robot, but I have some debugging suggestions which may or may not help. From your question, it seems like the web server can run ROS 2 and send the proper commands to execute actions, Can you provide the source of undock.sh ? Perhaps something is not getting set properly for ROS 2 to start. Also, what RMW are you using, and what version of ROS 2 are you running on the server and on the robot?
