Abstract

Aiming at the difficult problem of contact sampling of plant in complex geographical environment, a remote-controlled sampling method using an Unmanned Aerial Vehicles (UAV) is proposed. After configuration, mechanism parameter analysis & optimization, and dynamic analysis, a special lightweight sampling manipulator that integrates plant stem-and-leaf sample capture, cutting and storage is designed. The designed sampling manipulator is composed of a ball screw nut transmission pair and a symmetrical double-offset slider rocker. The minimum transmission angle of the rocker is 63.435°, the maximum opening displacement of the manipulator claw is 131 mm, and the cutting pressure is 226 N. Tests and experiments show that the sample manipulator has a mass of 2.35 kg, a cutting pressure of 214 N, and a maximum open displacement of the manipulator claws of 126 mm. It can be controlled locally or remotely using a UAV to grab, cut and storage plant samples with a diameter greater than 5 mm. The reliability of the sampling manipulator design and the feasibility of the sampling method are verified.
