 Every configuration variable is defined in [settings.py](https://github.com/equinor/isar-robot/blob/main/src/isar_robot/config/settings.py), and they may all be overwritten by specifying the variables in your ".env" file in [ISAR](https://github.com/equinor/isar). Note that the configuration variable must be prefixed with ROBOT_ when specified in the ISAR environment file.
