The catcher in the rye is a plant protection UAV, whose structure and appearance are transformed from the organic form of branches. The biggest highlight of the product is that it can collect wind energy through its own blades and convert it into electric energy for self charging. The main body of the UAV is equipped with a sound system to disperse the birds around the farmland by playing the scream sound of birds. It can protect the farmland without harming the birds. Let people and nature coexist harmoniously, which fully shows the design semantics of "The catcher in the rye".
