Work machine, control apparatus

A control apparatus comprising:

• a processor;
• and
• a memory that includes instructions, which when executed, cause the processor to execute:
• calculating a loading amount of an object in a loading target, for a work machine including a lower traveling body, an upper turning body mounted on the lower traveling body so as to freely turn, an attachment attached to the upper turning body and including an end attachment at a tip portion, and a first acquisition part configured to acquire information relating to a weight of the object held by the end attachment, the loading amount being calculated by adding the weight of the object held by the end attachment, each time the object held by the end attachment is discharged, based on the information acquired by the first acquisition part;
• and
• canceling the adding of the weight to the loading amount, in response to determining that a predetermined operation for discharging the object held by the end attachment is performed by the attachment and a position where the object is discharged does not correspond to the loading target.
