This paper analyzes principles and structures of various kinds of hydraulic systems of excavator with the help of the methods of construction design, and a new type of bypass channel control valve was designed to realize an unique hydraulic system of excavate robot, with which various kinds of hydraulic systems such as constant flow control, summation horse power control, negative control, positive control, and load sensing control systems may be achieved flexibly with simple structure and regulation. Several new types of energy saving control and intelligent control strategies of excavator have also been developed with the help of the flexible hydraulic system of the excavator robot that has been mentioned.
