Abstract: To highly accurately plan a load loading operation by a working machine so that a load after the load loading operation has a target shape. A working machine operation system is a working machine operation system with a bucket, including: an operation recording unit which records a loading operation of a hydraulic excavator when a load is loaded from the bucket onto a carrier; a shape acquiring unit which acquires a shape of the load loaded on the carrier after the loading operation; a correlation calculation unit which calculates a correlation of the loading operation and the shape of the load; and a loading operation calculation unit which calculates the loading operation based on the correlation and the target shape of the load.

Abstract: The present invention improves a work efficiency of an entire system for operating a plurality of working machines. An operation system of the working machine includes a work progress calculating unit 80 which calculates a work progress of a plurality of working machines or a scheduled ending time calculating unit 81 which calculates a scheduled ending time of a work by using the work progress calculated by the work progress calculating unit 80. A working machine of which an operation is switched from automatic control to remote control is determined from among the plurality of working machines by using the work progress or the scheduled ending time, and the operation system includes a centralized operation controller 43 which transmits an operation instruction to the determined working machine.

Abstract: External force acting on a hydraulic excavator bucket is calculated precisely. An external force measurement system for a work machine includes a hydraulic cylinder for driving a front unit of the work machine and a plurality of strain gauges for sensing strain amounts of a cylinder rod of the hydraulic cylinder. The plurality of strain gauges are formed of at least two sets of strain gauges. The at least two sets of strain gauges are arranged to oppose each other as viewed in an axial direction of the cylinder rod. The external force measurement system includes a load calculation section that is configured to calculate a load acting on the hydraulic cylinder based on difference between the strain amounts of the strain gauges arranged to oppose each other in each set.

Abstract: In a trace generation device including a trace generation determination unit that outputs a command of trace generation, when a difference of an actual load applied to a bucket and a reference load is equal to or larger than a predetermined value during excavation and a candidate trace generation unit that generates a trace in which a work amount is almost constant, after the command is output, the reference load is an estimated load and the command of the trace generation is output when the difference of the actual load and the estimated load is equal to or larger than the predetermined value during the excavation. As a result, working efficiency can be raised while a trace in which an excavation amount is almost constant is generated.

Abstract: Provided is a remotely operated manipulator which can be applied to a space which is wider on a back side than at an opening part, which has a simple structure, high stiffness, and high reliability. The remotely operated manipulator of the present invention includes: a circular base fixed to a wall surface; a beam which rotates on the circular base; a trolley which moves on the beam; and a mast which is raised and lowered with respect to the trolley and is mounted with a tool unit at a tip. Stiffness is improved by directly fixing the beam to the wall surface by a beam fixing device. Further, a work region is expanded by mounting a bending mast on the tip of the mast.
