Water-jet printer: sprinkler with watering-position control

Sprinklers with a rotating nozzle that is driven by a water current are commonly used in gardens. Many of these sprinklers sprinkle water over a circular or fan-shaped area in a garden. For common gardens that are not circular or fan-shaped, these sprinklers cannot sprinkle water over the entire garden area without sprinkling the immediate surroundings, such as the neighboring properties or public pavements. In this study, we developed a computer-controlled sprinkler and a web application that allow users to specify the watering locations easily.
