I know that - but:
I can't catch exeption (tool broken) - robot just stop working. If I have this option I can make program and catch exeption to tell robot (program) what he have to do. (go to store)
It would be great if exeptions (tool broken) can return NAME tool. Then I could be program so robot can make another tool for youself... it would be very usefull... without this I can just tell - if exeption (tool broken) go to storage get new tool and back to work..
