Title: SELF-MOBILE DEVICE
Abstract:
A self-mobile device (100, 100'), comprising a power supply module (120), a mobile module (130, 130'), a controller (150, 150'), a task execution module (140, 140') and at least two sensor circuits (200, 200') for detecting an external object. The sensor circuit (200, 200') comprises a sensor probe (201, 201'), and a signal processing component (210, 210') connected to the sensor probe (201, 201') and used for processing and converting an input signal of the sensor probe (201, 201'). The power supply module (120) is simultaneously connected to signal processing components (210) of at least two sensor circuits (200) so as to supply power to the signal processing components (210). The sensor circuit (200, 200') comprises a first filtering element, wherein the first filtering element is connected in parallel to the signal processing component (210, 210'), and one end of the first filtering element is connected to a power supply input end of the signal processing component (210, 210'). By connecting the first filtering element to the power supply input end, a voltage of the signal processing component (210, 210') can be relatively stable, thereby reducing the signal interference effect on the sensor circuit (200, 200'), and an output signal can relatively accurately reflect a situation change in the grassland detected by the sensor probe (201, 201').
