Linda shuts down completely without any obvious reason #35

Closed cdondrup closed 10 years ago

cdondrup commented 10 years ago

We discovered that our robot (PC and the base) shut down completely several times a day without any obvious reason. It started recently; yesterday for all we know. So far it happened three times: once in the middle of the room while patrolling and twice when she tried to dock. Before the charging started she just turned off everything. Is there any reason why this could happen, @chmartin21 ? The battery is at 98% but she just shut down regardless.

marc-hanheide commented 10 years ago

Did you check the logs? E.g. Syslog?? Or the kernel?

cdondrup commented 10 years ago

Tom checked the logs but couldn't see anything suspicious. The weird thing is that it's not only the PC but the whole base as well.

chmartin21 commented 10 years ago

Please can you read out the persistent error memory of the charger? This can be done by using the corresponing TCP call.

gestom commented 10 years ago

Can you be more specific about the call we should use to read the memory ?

chmartin21 commented 10 years ago

Please use getPersistentErrorCount() and getPersistentErrors() of the SCITOS unit. You also can use savePersistentErrors() to store the content of the error memory into a file. A complete list of the RPC can be found here: http://www.mira-project.org/MIRA-doc/domains/robot/SCITOS/index.html#ChargerHG2_Section

This is a photo of how even the base shuts down (this is the 4th time it happened, now is five times the fifth was immediately afterwards),

Jailander commented 10 years ago

This is what we get when using /robot/Robot.savePersistentErrors("name_of_the_file.txt")

Sorry I couldn't find a way to attach a text file in the comments

chmartin21 commented 10 years ago

We will check the content of the error memory and inform you as soon as possible.

Jailander commented 10 years ago

Hi, in issue #26 I left a video with an error we have been having on the charging station since this issue started, i think they can be related.

ml-stu commented 10 years ago

The errors look like ESD problems which cause a critical shut down of the robot. Are there some changes in the robots environment which may promote a electrostatic charge of the robot while driving? We are prepairing a new charger module for replacement. The up to date firmware double checks the error which causes the critical shut down and should not power of on ESD.

@cdondrup Is this closable?

Jailander commented 10 years ago

yes I haven't seen that happening again

cdondrup commented 10 years ago

Did not happen again.
