AI Technical Summary

Technical Problem

Existing weeding devices face challenges in accurately irradiating laser light on the stems of tall unwanted plants due to the instability caused by wind, making it difficult to pinpoint the growing point effectively.

Method used

A mobile weeding device equipped with a laser irradiator, a tilting device, and a device main body that includes a movement mechanism, which tilts the plant stems using a blower or contact member to align the stems with the laser beam, allowing precise irradiation at the base of the plants.

Benefits of technology

Improves the accuracy of laser light irradiation, efficiently removing unwanted plants while minimizing damage to crops and reducing the impact of natural wind, thereby enhancing the weeding process.
