Four-legged humanoid tea-picking control system and tea-picking method for unstructured tea garden

By using a quadrupedal human-like tea-picking control system, combined with multi-source visual perception and negative pressure lifting technology for dual-arm collaborative operation, the problems of shading and path interference during tea picking in unstructured tea gardens have been solved. This enables refined and low-damage tea picking, adapts to complex terrain, and meets the production requirements of high-quality tea.

AI Technical Summary

Technical Problem

Existing high-quality tea picking equipment struggles to address issues such as target bud and leaf obstruction, movement path interference, and difficulty in achieving ideal picking conditions before shearing in unstructured tea gardens. This results in insufficient picking selectivity, low efficiency, and high damage rates, failing to meet the production demands of high-quality tea.

Method used

A quadrupedal humanoid tea-picking control system is adopted, which combines multi-source visual perception, dual-arm collaborative operation and negative pressure lifting technology. Through quadrupedal robots, dual-arm collaborative operation, multi-source visual perception and closed-loop control based on negative pressure lifting and ideal position judgment, the system can achieve precise and low-damage tea harvesting.

Benefits of technology

It has achieved integrated operation of the entire tea-making process, reduced the damage rate of fresh leaves, improved the adaptability and harvesting stability of unstructured tea gardens, enhanced environmental adaptability and low damage advantages, and adapted to quadruped robots to overcome terrain limitations, enabling efficient harvesting in high mountain slopes and narrow-row densely planted tea gardens.
