Hello everybody,

I would like to use the position_controllers/JointPositionController after loading my robot in gazebo to move a joint up and down with the command

"rostopic pub -1 /joint1/command std_msgs/Float64 "data: 5.0""

But the joint1 is not moving. I do not know why? Do you have any advice?

My .yaml file for this joint1 is:

    type: position_controllers/JointPositionController
    joint: joint_base_link

the transmission in my urdf file for this joint1 is:

<transmission name="tran">
        <joint name="joint_base_link">
        <actuator name="joint">

Thank you very much!

This tutorial about ros_control could be helpful for you or straight out this post from The Construct.

I would like to see your topic list too, did you try to publish your message with sample talker? Maybe sending it once isn't enough.
