Abstract: A detection device and an indoor navigation system are provided. The detection device includes two detection modules each including a sound receiver for receiving sound from a peripheral object and a signal converting circuit that is electrically coupled to the sound receiver and that is configured to convert input signal from the sound receiver into a target spectrogram. The two spectrograms from the signal converting circuits have a time/phase difference, and at least one wireless earphone includes a storage unit and a judging circuit that is electrically coupled to the storage unit and the two signal converting circuits. The judging circuit is configured to compare any target spectrogram with basic spectrograms of the storage unit so as to determine which kind of objects the peripheral object is, and is configured to obtain an instant position of the peripheral object by the time/phase difference.

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.
