ABSTRACT:
The present invention relates to a method for automatically controlling prescribed work to be repeatedly done by the excavator. An electronic control using a processor and sensors is used to precisely control the work under program control regardless of the hardness of the ground. The controlling method according to the present invention utilizes stored data of the position of each of the joints of the actuators when the prescribed work is performed. During the repeated work, each joint is able to maintain its desired position regardless of the hardness of the ground. Further, because the operational mode can be stored at the same time as storing of the data for the prescribed work, the invention compares the operational mode with the repeated work. The performance speed of the repeated work can be controlled as much as intended by the operator. The repeated work can be performed with high speed when an unskilled operator stores the operation of the prescribed work with a slow speed. The work efficiency of the excavator is enhanced.
