Design and Simulation of Plant Sampling System in Complex Geographical Environment

Based on small rotor drone, the author proposal a sampling system scheme in complex geographical environment, which is composed of sampling manipulator, connection separator, image acquisition, remote controller and GPS positioning system, and realizes the function integration of plant sample, image information and geographic coordinate collection. This paper focuses on the sampling manipulator structure in detailed analysis and design, and the manipulator which is composed of ball screw and slider rocker mechanism is proposed. In order to finish further optimization, the author build dynamics model of manipulator to study the dynamics of grasping and cutting. Simulation results show that the proposed sampling system can solve the problem of plant sampling effectively in complex geographical environment, and provide technical support for the prototype development and practical application in the next stage.
