F1tenth joint string mismatch

[Lj1212am]

When I try to load in the f1tenth car in my env, the articulation joints found from the usd are mismatched to what is defined in the config file:

ValueError: Not all regular expressions are matched! Please check that the regular expressions are correct: 
	front_left_wheel_steer: []
	front_right_wheel_steer: []
	front_left_wheel_throttle: []
	front_right_wheel_throttle: []
Available strings: ['left_wheel_back', 'left_wheel_rotator', 'right_wheel_back', 'right_wheel_rotator', 'left_wheel_front', 'right_wheel_front']

You’ll need to rename the joints in the USD file or update the config file so they match 1:1. Once they do, the mismatch error should go away.

Yes but its unclear which joint maps to the throttle, that does not exist in the available joint strings/usd

I'm not sure if I'm understanding correctly, but the target mapping is up to you to decide (i.e. you can put in the rear two wheels or all four wheels). It looks like Isaac Lab is saying your joints are labeled:
['left_wheel_back', 'left_wheel_rotator', 'right_wheel_back', 'right_wheel_rotator', 'left_wheel_front', 'right_wheel_front']
Or, is our default configuration throwing this error?

If you refer us to a public fork of your code, I can take a look at your setup.

I've pushed the regex changes to update the config to match the naming of the urdf, try and see if it works now.
