Abstract: An autonomous movement system may include: a working robot configured to perform an operation while moving autonomously in a working area; a charging station configured to charge the working robot; a boundary wire defining the working area; and a station wire disposed at the charging station and electrically connected to the boundary wire. The working robot may include: a magnetic detecting unit configured to detect a magnetic field generated by the boundary wire and a magnetic field generated by the station wire; and a control unit configured to detect the station wire based on a detection result by the magnetic detecting unit. The charging station may include: a charging terminal configured to be electrically connected to the working robot; and a signal generator configured to supply an identical electric signal to the boundary wire and the station wire.

Abstract: A working robot may be configured to move and work autonomously. The working robot may include a robot body including a base and a bumper supported by the base, a working unit supported by the base, a movement mechanism configured to move the base, a movement motor configured to drive the movement mechanism, a first detection unit configured to detect a force that the bumper receives or displacement of the bumper relative to the base, a second detection unit configured to detect an angular velocity of the base or a state of the movement motor, and a control unit. The control unit may be configured to determine, based on a detection result detected by the first detection unit and a detection result detected by the second detection unit, whether the movement of the working robot is hindered by an obstacle.
