Automatic loading system

A working machine comprising:

• an upper slewing body;
• an attachment that is mounted on the upper slewing body so as to be raised and lowered and includes a distal end attachment configured to capture, move, and release a conveyance object;
• an actuator configured to drive the working machine;
• and
• a controller configured to calculate a target trajectory of the distal end attachment between a position where a capturing operation of capturing the conveyance object is performed and a position where a releasing operation of loading the captured conveyance object on a carrier is performed, and perform loading control, wherein the loading control is control that causes the working machine to repeatedly perform a series of operations including the capturing operation and the releasing operation;
• and
• the controller is configured to:
• output information related to the target trajectory to an external system that is arrangeable outside the working machine and is capable of displaying the information related to the target trajectory;
• and
• start the loading control on condition that, after the outputting of the information related to the target trajectory to the external system, a loading control start signal has been input from the external system to the controller.
