Hi, In the ros2_control_demos program: I test the (diffbot) diff-drive demo, and monitor the "hw_commands_" variable, while I publish the maximum val in cmd_val x = 1 this cause the value of "hw_commands_" is set to 66.0.

The value of cmd_val is: image description

I just wonder where the value is set? if we need to set this value where to set/configure it? Please help.....

Hi,

I guess that you are using some old version or publishing to a wrong topic, your velocity commands for DiffBot. Did you follow the exact manual from here?

If you are using your custom command for publishing velocities, please check that the topic name is "/cmd_vel".

P.S. I will check the code one more time and have no idea where this value could come from. I am using "master"-branch.

EDIT:

I see that you are using foxy. We didn't backport the "master" functionality to Foxy, so if possible please use newest "Galactic" or "Rolling" version.
