WORK MACHINE AND REMOTE-CONTROLLED WORK MACHINE SYSTEM

WIPO Patent Application WO/2023/189631

A1

The present invention provides a work machine and a remote control system for the work machine, with which any decrease in productivity of the work machine can be minimized while any decrease in quality of communication between the working machine and a remote control device is minimized. An excavator comprises a work device, an image-capture device for capturing an image of the work device and the surroundings thereof, and a control device for transmitting the image captured by the image-capture device as image data and controlling the action of the work device in accordance with a received operation signal. On the basis of a result of evaluating communication quality and the action status of the work device, the control device divides the image data into a plurality of items of image region data corresponding to a plurality of image regions in the image and sets a data reduction amount for each of the plurality of items of image region data. Image data for transmission, which is reduced on the basis of a set data reduction amount for each of the plurality of items of image region data, is then generated, and the image data for transmission is transmitted.
