Title:
TARGET PATH GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/230368
Kind Code:
A1
Abstract:
The present invention determines the target path of an attachment while suppressing the calculation load for generating the target path of the attachment. A controller (30) sets, as the starting point (P1) of an arm tip end target path (Ta), the position of an arm tip end part (15t) at the time when a contact detection unit (33) detects that a bucket tip end (17t) has come into contact with an excavation object (A). A controller (40) receives, in advance, information pertaining to the shape of the arm tip end target path (Ta). On the basis of the angle (α) of the surface of the excavation object (A), the angle (β) of intersection between the arm tip end target path (Ta) and the surface of the excavation object (A), the information pertaining to the shape of the arm tip end target path (Ta), and the offset amount (O) of the ending point of the arm tip end target path (Ta), the controller (40) sets the position of the ending point (P3).
