Abstract: The working robot may include: a movement unit configured to move the working robot; a movement motor configured to drive the movement unit; a battery; a control unit configured to control the movement motor; and a robot power receiver. The charging station may include: a station power transmitter; and a station plate placed on a ground. When the working robot is docked with the charging station and in an unchargeable state in which charging to the battery is unable to be started, the control unit may execute a docking retry process to move the working robot by the movement unit and dock the working robot again with the charging station. While the working robot is moving during the docking retry process, at least a part of the working robot may overlap the station plate as viewed in a direction perpendicular to the ground.

Abstract: A working robot may include a body, a movement unit, a working unit, a magnetic sensor supported by the body, and a control unit. The control unit may be configured to execute a working operation of causing the working unit to work while causing the movement unit to move the body. The control unit may execute, during the working operation, an operation-suspending process of suspending the working operation when a predetermined operation-suspending condition is satisfied, a first magnetic field searching process of causing the movement unit to move the body straight in a first linear direction by a first distance and assessing whether a wire magnetic field is detected by the magnetic sensor after the operation-suspending process, and an operation-resuming process of resuming the working operation when the wire magnetic field is detected by the magnetic sensor.
