Abstract

A robotic working apparatus includes: a working tool configured to perform work on a field; a working robot configured to perform the work while autonomously traveling on the field; and a processor configured to set a traveling route for the working robot and control motion of the working robot In a case where a first area and a second area are set on the field as working areas of the working robot, when the working robot moves from a work end point in the first area to a work start point in the second area, the processor sets a route from the work end point to a base, and a route from the base to the work start point, which are different at least in part from one another.

Claims (23)

1 . A robotic working apparatus comprising:

a working robot having a working tool configured to perform work on a field, the working robot configured to perform the work using the working tool while autonomously traveling on the field;

a processor configured to set a traveling route for the working robot and control motion of the working robot; and

a memory configured to be able to communicate with the processor, wherein:

a first area and a second area are set on the field as working areas of the working robot, and when the working robot moves from a work end point in the first area to a work start point in the second area, the processor sets a route from the work end point in the first area to a base, and a route from the base to the work start point in the second area;

the route from the work end point in the first area to the base is different at least in part from the route from the base to the work start point in the second area;

at least one relay point is selected from a plurality of relay points;

the route between the base and the work start point in the second area includes:

a first straight line from the base to a first said selected relay point or a second selected relay point, and

at least a second straight line from the first selected relay point or a third said selected relay point to the work start point in the second area; and/or

the route between the work end point in the first area and the base includes:

a third straight line from the work end point in the first area to the first said selected relay point, and

a fourth straight line from the first said selected relay point to the base.

2 . The robotic working apparatus according to claim 1 , wherein the base is a charging base for the working robot.

3 . The robotic working apparatus according to claim 1 , wherein a relay point is provided between the work end point and the base and/or between the base and the work start point.

4 . The robotic working apparatus according to claim 3 , wherein a plurality of relay points are provided.

5 . The robotic working apparatus according to claim 1 , wherein the work end point in the first area and the work start point in the second area are different from one another.

6 . The robotic working apparatus according to claim 1 , wherein at least one of the work start point in the first area, the work end point in the first area, and the work start point in the second area is set to be different from that set in the past.

7 . The robotic working apparatus according to claim 5 , wherein patterned traveling is set in the first area and the second area, and an angle of the patterned traveling set this time is changed from an angle of the patterned traveling set in the past.

8 . The robotic working apparatus according to claim 1 , wherein when the working robot moves from the work end point in the first area to the work start point in the second area, the working tool does not work.

9 . The robotic working apparatus according to claim 1 , wherein the working tool is a blade device to perform mowing on the field.

10 . The robotic working apparatus according to claim 1 , wherein the working tool is a collection device configured to collect target objects on the field.

11 . The robotic working apparatus according to claim 1 , wherein a space area is provided between the first area and the second area.
