parseURDF error #342

Closed dan9thsense closed 5 months ago

dan9thsense commented 5 months ago

This error is repeated over and over when the sim starts and then occasionally throughout. Does not seem to harm anything, but should probably be addressed.

Yes, this is a known error and has to do with the gazebo state log generation which is used for trial playback. You can see that if you turn the record_state argument to false this error goes away. This appears to be a gazebo bug not an ARIAC bug from what I can tell and like you mentioned I have not seen it cause any other issues than the log errors.
