Abstract

A process for automatically controlling power excavators is disclosed. In the process, the motions of the working members in accordance with lever handling motions of an operator are stored in a controller and reproduced to approximately conduct the operation. The operational errors of the reproduced motions of the working members are corrected and compensated in accordance with newly inputted lever handling motions of the operator while approximately conducting the operation, thereby accomplishing the desired operation. The process optimally controls the excavators regardless of working conditions, thereby improving the operational precision of the excavators. The above process does not need to use any sensors.
