Abstract

The autonomous travel work machine executes the predetermined operation on the operation target while autonomously traveling, and includes: a driving unit driving a wheel to cause a main body to travel; a reception opening disposed on a side face of the main body regarding a traveling direction of the main body; an operation unit mounted on the main body and executing the predetermined operation on the operation target; and a control unit that controls the driving unit switchably between a first operation of causing the main body to travel against the operation target and executing the predetermined operation by the operation unit on the operation target and a second operation of moving the main body to a position where the operation target can be received in the reception opening and executing the predetermined operation by the operation unit on the operation target received in the reception opening.

Claims17

Dependent claims

An autonomous travel work machine comprising a main body and a wheel, the autonomous travel work machine being configured to execute a predetermined operation on an operation target while autonomously traveling, the autonomous travel work machine comprising:

a driving unit that is a motor configured to drive the wheel to cause the main body to travel;
a reception opening disposed on the main body;
an operation unit that is a cutting blade mounted on the main body and configured to execute the predetermined operation on the operation target;
a control unit that is a processor configured to control the driving unit switchably between a first operation of causing the main body to travel with respect to the operation target and executing the predetermined operation by the operation unit on the operation target and a second operation of moving the main body so that the operation target can be received in the reception opening and executing the predetermined operation by the operation unit on the operation target;
and
a detection unit configured to detect the operation target, wherein
the control unit switches between the first operation and the second operation in accordance with a detection result of the detection unit,
the detection unit includes a contactless detection unit configured to contactlessly detect the operation target, and a contact sensor configured to detect contact with the operation target,
in the second operation, when the contactless detection unit detects the operation target, the control unit turns the main body so that the operation target is received in the reception opening, whereby executing the predetermined operation by the operation unit on the operation target.
