# Collecting Images and Raw Analysis
Every time the robot takes a picture it is updated on the web interface, during development it is occasionally useful to be able to also keep a log of pictures that have been analysed to check the camera focus, motion blur etc.
# Gathering Data:
- Add a file with the name "collect_images.txt" to the USB stick to collect the images
- Add a file with the name "log_markers.txt" to the USB stick to collect analysis of images
- Insert the USB stick before turning the robot on
- Remember to fully shut down the robot before removing the USB stick
WARNING
Collecting all images may slow down the processing time from your robot - Use with care!
