[Discourse.ros.org] [TurtleBot] Turtlebot3 - Joule stalled

Saurabh Bansal via ros-users


Hi

Turtlebot 3 - Waffle ... Joule - after installing Joule following the official documentation (Ubuntu 16.04 LTS) : everything works fine...problem: Joule stops working/running after approx 10min up - independently if operated on 12V/3A external power supply or with the battery provided with the Turtlebo3 kit. Logs don't show any weird symptoms...

Any ideas? pls help...

Tnx in advance
ml

First thing to check, what is the temperature doing? Is the module overheating?

Also, does anyone know what the replacement for the Joule is, now that they are EOL?
Thanks :slight_smile:

Tnx Ilia for the hint...checking continously temp via /sys/class/thermal zones 0-7 - max. 45C ... assuming that isnt the root cause. Keep on digging...Best ml

...quick update: if you push the Power button (SW2) the "stalled" system recovers - even the Unix sessions...
...did I miss something here - kind of "sleep mode" /   hibernation mode - some BIOS settings?

Interesting.  Our bot was doing the same thing, with symptoms just like a software crash, so that's what I assumed.  Maybe it is going into a sleep mode of some sort.
