Self-propelled device
First Claim
1. A self-propelled device comprising:
- a traveling element; and
a marker configured to guide the traveling element, the traveling element including;
a body case;
a driving wheel rotatably provided in the body case to enable the body case to travel;
a motor configured to allow the driving wheel to be rotationally driven;
a traveling element-side transmitting unit configured to transmit a signal including traveling element-side identification information with directivity of a predetermined width;
a traveling element-side receiving unit configured to be receivable of a signal with directivity wider than the directivity of the traveling element-side transmitting unit;
a control unit configured to control transmission of a signal from the traveling element-side transmitting unit, reception of a signal by the traveling element-side receiving unit, and drive of the motor, the marker including;
a marker-side receiving unit configured to receive the signal including the traveling element-side identification information; and
a marker-side transmitting unit configured to transmit a signal including marker-side identification information when receiving the signal including the traveling element-side identification information by the marker-side receiving unit, wherein,the control unit causes a signal including the traveling element-side identification information to be transmitted sequentially in a plurality of directions, determines whether the signal including the marker-side identification information is received in each direction, decides a direction where the body case to travel based on a direction that the signal including the marker-side identification information is received, and controls drive of the motor to allow the body case to travel to the determined direction.

Abstract
A vacuum cleaner includes a first transmitting unit transmitting a signal including first identification information with directivity of a predetermined width, and a first receiving unit receiving a signal with directivity wider than directivity of the first transmitting unit. A charger includes a second receiving unit receiving the signal including the first identification information, and a second transmitting unit transmitting a signal including second identification information when the second receiving unit receives the signal including the first identification information. A first control unit controls, when the signal including the second identification information is received by the first receiving unit, drive of a motor to allow a body case to travel based on a direction that the signal including the first identification information is transmitted.
