Abstract: A border-signal generating and wire winding device for border recognition of a self-propelled mower includes a seat; a reel rotatably installed on the seat; a lever provided at one end of the reel for a user to operate and rotate the reel; two power sockets provided on the seat or on the reel; an electric wire removably wound around the reel and having two plugs at two ends thereof for being detachably plugged into the two power sockets; and a signal-generating module provided on the seat or on the reel and electrically connected to the two power sockets. When the electric wire is connected to the two power sockets through the two plugs, the signal-generating module continuously generates a border signal that is continuously transmitted to the electric wire through the two power sockets.

Abstract: A mobile robotistic mopping machine is formed of a body frame, a mop cloth, a power device, and a control device. The power device includes two opposite wheels and two opposite motors connected with the respective wheels for driving the wheels to rotate to further enable the body frame via the wheels to make the mop cloth move forward for cleaning the ground. The control device is electrically connected with the motors for controlling the motors. When the body frame makes the mop cloth move forward for a predetermined distance, the control device can control and make one of the motors reversely rotate and meanwhile make the other keep normal rotation to further enable the body frame to make the mop cloth turn for a predetermined angle and then keep moving forward.

Abstract: An electronic fence generator includes a cylindrical body, a ground stake downwardly extended from the bottom of the cylindrical body, and an ultrasonic transmitter, an infrared transmitter and an infrared receiver mounted in the cylindrical body. The ultrasonic transmitter is adapted for transmitting an ultrasonic signal to create a collision avoidance range around the cylindrical body. The infrared transmitter is adapted for transmitting an infrared signal in a signal transmitting direction. The infrared receiver is adapted for receiving an infrared signal from another electronic fence generator in a signal receiving direction different from the signal transmitting direction. Thus, the electronic fence generator can be used for creating a virtual electronic fence for restricting an automatic lawn mower to the range defined by the electronic fence.
