Application of Four-Wheel Four-Steering Row Spacing Adjustable Chassis in Seedling Transplanting Robots

Facing the heavy and inefficient manual transplanting operations, seedling transplanting robots equipped with wheeled chassis are becoming powerful assistants in intelligent agriculture. Through efficient and precise automated operations, it not only significantly liberates human resources and enhances production efficiency, but also effectively reduces seedling damage and increases the survival rate of transplanting.

The wheeled chassis equipped on the seedling transplanting robot features four-wheel drive and four-wheel steering configurations, allowing for flexible adjustment of the wheel track and wheelbase. This overcomes the working conditions of non-standard ridge spacing. While enabling arbitrary adjustment of the plant spacing, it comprehensively ensures the steering flexibility and planting accuracy of the agricultural robot. The wheeled robot chassis is equipped with a built-in VCU, supporting multiple navigation methods such as laser navigation, Beidou navigation, and follow navigation, enabling the seedling transplanting robot to navigate autonomously along the ridges precisely. From taking seedlings, transporting them to planting, the entire process is fully automated, liberating the staff from repetitive labor and effectively avoiding the problem of uneven density in manual transplanting. After completing a row of transplanting, the robot can independently perform efficient row changing operations. Meanwhile, the maximum load capacity of the 4 wheel drive chassis is 300kg, which can meet the transportation needs of the vast majority of agricultural materials and ensure the efficiency and continuity of the entire transplanting process.

Integrating five core advantages - flexible steering, precise navigation, fully automatic transplanting, adjustable plant spacing and efficient row changing - the seedling transplanting robot can significantly enhance operational efficiency, effectively reduce reliance on manual labor, and minimize seedling damage through standardized operations to ensure survival rates. The 4 wheel drive chassis equipped on the seedling transplanting robot provides a solid foundation for the realization of these functions, promoting agricultural production to move towards a more efficient and intelligent direction, especially suitable for large-scale planting scenarios.
