Taking and verifying a log

Modified 2018-09-26 by liampaull

Record the log

Modified 2018-11-10 by liampaull

laptop $ docker -H hostname.local run -it --net host --name logger -v /data/logs:/logs duckietown/rpi-duckiebot-logger:master18

This will only log the imagery, camera_info, the control commands and a few other essential things.

Verify a log

Modified 2018-11-10 by liampaull

Either copy the log to your laptop or from within your container do

$ rosbag info FULL_PATH_TO_BAG --freq

Then:

  • verify that the “duration” of the log seems “reasonable” - it’s about as long as you ran the log command for

  • verify that the “size” of the log seems “reasonable” - the log size should grow at about 220MB/min

  • verify in the output that your camera was publishing very close to 30.0Hz and verify that you joysick was publishing at a rate between 3Hz and 6Hz.
