Route setting system

A path setting system for use in a working machine including a lower travelling body, an upper slewing body mounted on the lower travelling body slewably about a slewing central axis extending in a vertical direction, and an attachment mounted on the upper slewing body to perform a work, the path setting system for setting a target path of an attachment specific portion being a specific portion of the attachment, comprising:

• a three-dimensional information acquisition part that acquires three-dimensional information on an obstacle specific portion being a specific portion of an obstacle around the attachment;
• and
• a controller that sets a target path of the attachment specific portion from a predetermined start point to a predetermined end point, wherein
• the controller determines whether the obstacle specific portion exists or not between the start point of the target path and the end point of the target path on the basis of an acquired result by the three-dimensional information acquisition part,
• the controller sets an avoidance path as the target path when the obstacle specific portion is determined to exist between the start point of the target path and the end point of the target path, and sets a non-avoidance path as the target path when the obstacle specific portion is determined not to exist between the start point and the end point,
• the avoidance path is a path along which the attachment specific portion moves from the start point to the end point while the attachment is led to an avoidance operation of avoiding the obstacle, and
• the non-avoidance path being a path along which the attachment specific portion moves from the start point to the end point while the attachment is not led to the avoidance operation.
