Publication number: 20230407594Abstract: A contact of an attachment with an obstacle is suppressed, and concurrently, a wasteful motion of the attachment is suppressed. When determining that an obstacle specific portion exists between a start point and an end point, a controller sets an avoidance path as a target path. The avoidance path is a path along which an 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. When determining that the obstacle specific portion does not exist between the start point and the end point, the controller sets a non-avoidance path as the target path. The non-avoidance path is 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.Type: ApplicationFiled: August 5, 2021Publication date: December 21, 2023Applicant: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Masaki AKIYAMA, Takayuki DOI, Koji YAMASHITA
