Failed to Load mobile_base_controller [closed]

edit

Hi.

I cannot load the differential controllers for my robot. I am having the following message error ( I will use an image because the output of the terminal is too big):

summarizing it: "Could not load controller “mobile_base_controller because…” and: (1)Failed to load mobile_base controller (2) Failed to load jibo2/right_wheel_velocity_controller (3) Failed to load jibo2/left_wheel_velocity_controller

I imagine the error 2 and 3 happens because of the first .yaml (diff-drive type) was not correctly loaded. I tried to load the yaml file without put the name space, out of the group=“jibo2” area…but no success.

I have already seen this video https://www.youtube.com/watch?v=9OWxX... trying to answer this similar question issue https://answers.ros.org/question/2895... but unfortunately for me it did not work.

So My LAUNCH file is below:
