Automated Pollination Device

Robot for self- and cross-pollination using depth cameras and interchangeable end-effectors

This technology is a mechanism and control system for an automated pollination robot equipped with a greenhouse navigation unit, a robotic arm, a depth camera-based pollination target detection unit, and interchangeable end-effectors that perform self-pollination (brush-driven) or cross-pollination (pollen spraying) depending on the target crop.

The technology addresses the need for alternative pollination methods to solve crop yield reduction and malformed fruit issues caused by declining honeybee populations, while automating efficient self- and cross-pollination tasks tailored to specific crop types.

The system features a LiDAR-based autonomous navigation unit, a detection unit that identifies flower locations using QR codes and depth cameras, a self-pollination end-effector that moves a brush forward and backward via a servo motor, rack, and pinion mechanism, and a cross-pollination end-effector that sprays pollen using an air supply pump, ejector, and spray nozzle.

Key Features:

• A navigation unit that travels within the greenhouse and supports the pollination target detection unit and the pollination work unit installed on top.
• A pollination target detection unit installed on the navigation unit that detects pollination targets using a depth camera and other sensors.
• A pollination work unit installed at the end of the robotic arm that performs pollination tasks under the control of the control unit.
• A self-pollination end-effector equipped with a brush that is controlled to move forward and backward by a spur gear, pinion, and rack driven by a servo motor.
