2017-10-20 12:32:38 -0500	marked best answer	Is there something like a observer-node? Hello community, I am having the problem that once in a while some of my nodes randomly die due to hardware issues (overheating, miserable cable connection, problems in usb_read/write errors, etc.) that can't be faced by me. I would like to know if I can create some sort of observer-node, that listens to dying nodes and can thus initiate some recovery behavior. This is pretty important in my case, as sometimes my camera-node dies which leads to the situation, that the robot doesn't have any clue where it's located at. If I had this observing node I could most likely manage the situation properly, without having to reboot everything. I am really looking forward to your replies. Best regards, Till
