Classification: CPC G  A | IPC A  G

Claim 0:
1. An autonomous work machine that works in a work area while autonomously traveling in the work area using a perimeter map showing a shape of a perimeter of the work area, comprising:
at least one processor circuit with a memory comprising instructions, that when executed by the processor circuit, causes the at least one processor circuit to at least:
specify, based on information of a position detection unit configured to detect position information, a self-position of the autonomous work machine;
determine that the autonomous work machine has reached a perimeter portion of a no-work area positioned within the work area, in a case in which a magnetic field of a wire, which is not included in the perimeter map, has been detected based on outputs of magnetic sensors while travelling in the work area based on the self-position;
control the autonomous work machine to do a lap along the perimeter portion in a case in which the autonomous work machine is determined to have reached the perimeter portion; and
generate a map that shows the shape of the perimeter portion of the no-work area based on the information of the self-position of the autonomous work machine obtained during a travel of the lap along the perimeter portion of the no-work area.
