Self-propelled electronic device
First Claim
1. A self-propelled electronic device that is supplied with power from a charging base installed in a predetermined position and automatically travels to a position away from the charging base, the self-propelled electronic device comprising:
- a travelling control unit that makes the self-propelled electronic device move automatically by controlling a rotation of a wheel;
a rechargeable battery that supplies power for performing travelling control during the automatic travelling;
a charging base searching unit that searches for a position of the charging base;
a control unit;
whereinwhen the control unit determines that returning to the charging base is required, the control unit performs return processing by which the self-propelled electronic device is made to come to rest and then rotate in a resting state by the travelling control unit and, when the charging base searching unit searches for a direction in which the charging base lies and detects the direction in which the charging base lies, the self-propelled electronic device moves in the direction in which the charging base lies;
a remaining battery level detecting unit that detects a remaining battery level of the rechargeable battery; and
a storage unit that stores in advance battery information which is compared with the detected remaining battery level;
whereinwhen the detected remaining battery level becomes less than or equal to a first remaining level threshold value P1 stored as the battery information, the control unit determines that returning to the charging base is required and performs the return processing.

Abstract
There is provided a self-propelled electronic device that is supplied with power from a charging base installed in a predetermined position and automatically travels to a position away from the charging base, the self-propelled electronic device including: a travelling control unit that makes the self-propelled electronic device move automatically by controlling the rotation of a wheel; a rechargeable battery that supplies power for performing travelling control during the automatic travelling; a charging base searching unit that searches for the position of the charging base; and a control unit; wherein, when the control unit determines that returning to the charging base is required, the control unit performs return processing by which the self-propelled electronic device is made to come to rest and then rotate in a resting state by the travelling control unit and, when the charging base searching unit searches for the direction in which the charging base lies and detects the direction in which the charging base lies, the self-propelled electronic device moves in the direction in which the charging base lies.
