Sucessfully publishing message but failed to control Mira's motion

Hi there,

I’m doing U2.3 now, want to add real actuators to move one Mira’s joint. I followed the example steps in the notebook, but failed to control the joint state (Mira moved as if there is no control at all). I checked the publisher using

rostopic echo mira/roll_joint_position_controller/command

I can see the data I published, it’s correct. The subscribers are:

 * /gazebo (http://2_xterm:40999/)

I also tried to use different PID parameters but it doesn’t work.

Thanks for your help in advance.


Hello @hanbang ,

I’ve sent to your e-mail a package that is working correctly until the section you refer to (you can control the roll_joint by publishing into the topic). Please have a look at it and check where your package is different.

Thanks for your reply.
I will have a try.
