AI Technical Summary

Technical Problem

Existing rice breeding equipment suffers from problems such as incomplete cutting, significant seed damage, severe contamination, and low sampling efficiency, especially for seeds with husks and seeds transported by robotic arms, where incomplete cutting is inefficient.

Method used

A high-throughput flexible clamping laser sampling device is adopted, which uses a suction nozzle to flexibly clamp the seeds and combines a vision camera and laser for precise cutting. Through an automatic sorting module and a sample collection module, efficient and non-destructive seed sampling is achieved.

Benefits of technology

It achieves high-precision, low-damage, and pollution-free rice seed sampling, improving the efficiency and quality of the breeding process and reducing mechanical damage and pollution to seeds.
