METHOD AND SYSTEM FOR AUTOMATIC CONTROLLING EXCAVATOR

摘要

PURPOSE: A method and a system for automatically controlling an excavator are provided to efficiently avoid obstacles by sensing the obstacles. CONSTITUTION: A system for automatically controlling an excavator comprises a constraint condition storage unit(100), a force reflection detector unit(102), and a control unit(104). The constraint condition storage unit stores a pre-set constraint condition. The constraint condition comprises one of an excavating area, a unit moving area, and obstacle estimation coordinate information. The force reflection detector unit senses power reflection applied to an actuator when excavating. If the power reflection exceeds a threshold, the control unit stores the coordinate information.
