Publication number: 20210002860Abstract: A remote operation system for a working machine includes a control device enabling an operator wearing a wearable display to grasp the surrounding situation of himself/herself. The control device includes an operation intention judgment section judging the presence/absence of an operator's operation intention to a remote operation lever based on the contents of acquired judgment information, and a display image switching section. With judgment of presence of the operation intention, the display image switching section makes a working area image taken by a working area image taking camera be displayed in a particular display area of the wearable display. With judgment of absence of the operation intention, the display image switching section stops the display of the working area image in the at least a part of the particular display area and switches it to a surrounding visual-recognition allowing area allowing the operator to visually recognize the surroundings.Type: ApplicationFiled: February 6, 2019Publication date: January 7, 2021Applicant: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Masaki OTANI, Yoichiro YAMAZAKI, Seiji SAIKI, Hitoshi SASAKI
