This paper describes the recognition method of operation with hydraulic excavators. Features of operation are extracted from the lever operating data to recognize the operation. Using fuzzy reasoning depending on these features, high accuracy recognition became possible for various operators. We have also developed tuning method for membership functions in fuzzy reasoning. Even if the type of hydraulic excavators is changed, high accuracy recognition is maintained by this method. These methods were experimentally shown to be useful and have been put to practical use.
