Back up your data

During the operating system’s installation, all files present in the machine will be erased. To avoid losing important data, please back your files up in a separate storage. SENSR-related files are the following:

Project files

Project files contain parameters for a given SENSR project, they are usually located in the following directory: /home/seoulrobotics/projects. To avoid calibrating and tuning your project again, please backup those files to your external storage.

Presets

Presets are used to store and transfer a given set of parameters from machine to machine. Specific presets are stored in the following directory: /home/seoulrobotics/presets. If you have been using some specific presets, please transfer them to your external storage.

Rosbags

Rosbags are used to store raw pointcloud data. They can be used to replay a given set of events in SENSR. Rosbags are usually stored in a location selected by the user. If you would like to keep some of them, please back them up to your external storage.

Custom SDK scripts

If you are using the SDK in the same machine as SENSR, your scripts must be backed up.

SDK Scripts can be deployed on any repertory of your machine. Users generally store their SDK under /home/sensr_sdk. Please transfer your custom scripts to an external storage.
