A fluid discharger includes: a discharge nozzle configured to discharge fluid; a first rotation device configured to rotate the discharge nozzle; and a control device configured to control the first rotation device by remote operation. The control device includes a first mode control unit including a first automatic control unit configured to automatically perform reciprocating control of the discharge nozzle in a first rotation range set for each of the fluid dischargers; and a first switching unit configured to switch between a control signal to be outputted from the first automatic control unit and a control signal to rotate the discharge nozzle by a first rotation angle designated by remote operation. In a dust suppression system, this configuration can control the direction of the discharge nozzle by remote operation, and also can automatically reciprocate the direction of the discharge nozzle within a predetermined range.

Various embodiments relate generally to computer vision and automation to autonomously identify and deliver for application a treatment to an object among other objects, data science and data analysis, including machine learning, deep learning, and other disciplines of computer-based artificial intelligence to facilitate identification and treatment of objects, and robotics and mobility technologies to navigate a delivery system, more specifically, to an agricultural delivery system configured to identify and apply, for example, an agricultural treatment to an identified agricultural object. In some examples, a method may include calculating an amount of light originating from a light source sensed at a location in which an agricultural object is interposed between the light source and an image capture device, causing emission of an obscurant, and directing the obscurant to a region interposed between the light source and the agricultural object.
