Document Type and Number:
WIPO Patent Application WO/2024/075650
Kind Code:
A1
Abstract:
The present invention predicts a current motion mode and a next motion mode according to a detection result of a state recognition sensor and when a work machine is in a state of transitioning from the current motion mode to the next motion mode, switches a control mode indicating the type of motion control of the work machine to a control mode corresponding to the next motion mode out of a manual operation mode in which a work device conducts a motion according to an operation of an operation device and an automatic operation mode in which the work device conducts a motion independently of the operation of the operation device, and starts motion control of the work machine. The present invention can thereby change the motion of automatic operation more easily and appropriately according to a situation of a work site and can reduce fatigue of an operator while suppressing a decrease in productivity.
