Commenting out leads to reflash to stock fw

[Andoramb]

Hi, how cool is this xD, I was just looking for this, thanks!

However, if I follow the description:

In /opt/rockrobo/cleaner/conf/ruby_chassis.cfg comment out the last two drivers, writelog and ruby_support.
Uncommenting those drivers (especially the writelog) causes several reboots and finally the robot flashes itself back to stock firmware :-/

1. I tried to add provides ["log:2"] - instead of 0 and keep the previous writelog driver, but still causes a freeze.
2. I also tried to change the location to /mnt/data/bumper.log to read out the file, and see how the bumper is logged.

ps.: it is also possible to use the script with cmus instead of sox:
ex. "cmus-remote -p" -> this way if you have a playlist, you can play sound clips randomly 💃

Another thing that I observed:

create a new writelog driver, that outputs file to: log_directory "/run/shm/derp"
But then still read /dev/shm/PLAYER_fprintf.log from the script? (is that the same as log_directory "./logs"?)

To be honest I only tested it shortly, mine didn't reflash itself after several restarts although I might check what my robo is up to later (haven't started it in a few weeks). But I'm not running the latest firmware either..

But then still read /dev/shm/PLAYER_fprintf.log from the script? (is that the same as log_directory "./logs"?)

Yeah that's something I didn't quite figure out, the output file is ignored for some reason and sensor output is written to PLAYER_fprintf.log

[Andoramb]

Exactly! I managed to make it work with PLAYER_fprintf.log but it's a bit slow.

I found that you can also write driver based on Alsa, for example:

driver
(
  name "alsa"
  provides ["audio:0"]
  samples ["sample1.wav" "sample2.wav" "sample3.wav"]
  mixerfilters ["master" "pcm" "capture"]
)

And that is fine. but how to connect with
requires ["bumper:0"] - and based on a value (1), play the audio file?

Funny :)

Hey, did you ever get this to work? xD

I intend to attempt this later on this weekend.

Which model works the best?

Sorry I can probably not help, I haven't run it again. I was using the first generation Xiaomi/Rockrobo vacuum at the time (the same model as in the 34C3 talk about rooting vacuums), I don't know if this still runs on newer firmwares since haven't updated/rooted my vacuum since 2019
