Abstract: A weeder robot includes a movable carrier and a blade module assembled to the movable carrier. The movable carrier includes a map creating module and a control module that is electrically coupled to the blade module and the map creating module. The map creating module includes an infrared unit and a vision sensing unit. The infrared unit can emit and receive an infrared light. The vision sensing unit can obtain an image information in a non-contact manner. The movable carrier can be used to move in a court, so that the map creating module can generate a three-dimensional (3D) court map through cooperation between the infrared unit and the vision sensing unit. When the weeder robot performs a maintenance process, the control module drives the blade module to weed a portion of a lawn higher than a predetermined height according to the 3D court map.

Abstract: A cleaning system and a cleaning method are provided. The cleaning system includes a main body, an air suctioning device, a light source, an optical sensor, a memory and a processing unit. The air suctioning device includes an air flow passage and a fan-motor assembly that is disposed in the air flow passage and generates a suction force to suction outside air through the air flow passage. The light source emit light to the air flow passage. The optical sensor captures a plurality of successive image frames from the air flow passage. The processing unit is configured to: obtain first and second image frames from the successive image frames; compare the first image frame with the second image frame to identify dust particles; obtain a particle feature of the dust particles; and determine a current cleanness condition according to the particle feature.

Abstract: A temperature detecting apparatus is provided. The temperature detecting apparatus includes a movable carrier and a thermal sensor. The movable carrier includes a control module, and is movable in a working place according to a designated command. The thermal sensor is assembled to the movable carrier and is electrically coupled to the control module. When the movable carrier is moved according to the designated command, the thermal sensor is configured to detect the working place so as to generate an immediate temperature distribution of the working place. Moreover, when the immediate temperature distribution generated from the thermal sensor has an abnormal temperature value, the control module is configured to emit a warning signal to an external apparatus.
