Abstract

A charging apparatus for a mobile robot enabling the mobile robot to move relatively freely even during charging using a wiring member, while preventing occurrence of an inconvenience such as damage to the wiring member, is provided. The charging apparatus includes a charging power source, a control board which controls the charging power source, and a wiring members for use in supplying electric power from the charging power source to a battery mounted on the mobile robot. The wiring member connected to the mobile robot to follow the movement of the robot. The charging apparatus further includes a detector which detects tension applied to the wiring member. When the wiring members is pulled, an appropriate measure to stop the mobile robot or disconnect the wiring member from the robot is taken in accordance with a signal from the tension detector.

Claims

1. A charging apparatus for charging a battery mounted on a mobile robot, comprising:

a charging power source;

a control board which controls the charging power source;

a wiring member having an end connected to the charging power source and another end connected to the mobile robot and following movement of the mobile robot, electric power being supplied from the charging power source via the wiring member to the battery mounted on the mobile robot; and

a tension detector which detects tension applied to the wiring member.

2. The charging apparatus for a mobile robot according to claim 1, wherein in the case where the tension detector detects the tension applied to the wiring member, the control board transmits a motion restriction signal to the mobile robot to instruct that the movement of the mobile robot should be restricted.

3. The charging apparatus for a mobile robot according to claim 2, wherein the motion restriction signal is a signal prohibiting movement of the mobile robot in a direction away from the charging apparatus.

4. The charging apparatus for a mobile robot according to claim 2, wherein the motion restriction signal is a signal causing the mobile robot to move in a direction approaching the charging apparatus.

5. The charging apparatus for a mobile robot according to claim 2, wherein the motion restriction signal is a signal causing the mobile robot to stop.

6. The charging apparatus for a mobile robot according to claim 1, wherein in the case where the tension detector detects the tension applied to the wiring member, the control board stops supply of the electric power from the charging power source.
