While autonomous systems in general, and Percepto AIM in particular, are built to be extremely accurate and to eliminate much of the risks of human error, nothing is 100% accurate. There remains at least a slight risk of a fault going undetected or flagging of an issue that turns out to be nothing, which can be a costly mistake. That being said, autonomous inspection methods have much lower false positives and false negatives than traditional manual methods, and increased inspection frequency implies that any false positives or undetected risks will be caught in the next inspection round.
