User-defined line-tracking autonomous sprayer

Autonomous agricultural spraying robot using camera-based line tracking

This technology is an autonomous agricultural spraying system that uses a machine learning-based camera to detect user-defined colored line markers. It autonomously follows the detected path while controlling the chemical spray volume and the power sprayer output.

Conventional large-scale agricultural sprayers (such as speed sprayers) struggle to enter narrow fields, while expensive RTK/GPS-based autonomous systems are only suitable for large-scale farming and impose a significant financial burden on farmers.

This technology features a compact aluminum profile chassis equipped with a line-tracking camera, a control unit with a joystick/potentiometer, and a spraying unit that regulates flow by controlling the carburetor via a servo motor, enabling low-cost automation of spraying tasks in narrow areas.

Key Features:

• A robot body and a driving unit configured to move relative to the body
• A spraying unit installed on the body that performs spraying tasks in coordination with the movement of the driving unit
• A path recognition unit installed on the body that detects line markers via a camera
• A control unit that manages the driving and spraying units based on the path recognition unit's signals, allowing for the selection of autonomous, manual, or neutral modes
