SUMMARY
In this research, a wireless remote-controlled (RC) spraying machine is developed based on the S3C6410 embedded controller. This spraying machine is composed of a rotary pesticide selection unit, a real-time mixing unit, a multi-angle spraying unit, an image acquisition module, an embedded control module, a wireless communication module, and an intelligent mobile platform. It is especially designed for hilly areas, greenhouses, orchards, and other environments that are not accessible to large and medium-sized spraying machines. The wireless RC machine achieves precise proportional and multi-angle flexible spraying while avoids liquid waste and direct operator–liquid contact.
