Can not run the tiago example in the differential-drive mode

[yj-Tang]

I used the same configuration as the Jackal robot to add the Tiago robot, but I encountered an error:

It's possible that the error is caused by the configuration to control the arm joints along with the mobile base joints. Based on the information from the debug, we may have to update the urdfenv?

I'll close this issue since the problem was the urdf file itself.
