Abstract: Tea is an important cash crop in China. The contribution rate of high-quality tea is nearly 70% in tea production. The high-quality tea is harvested by hand plucking, which is inefficient and labor intensive and leads to higher costs. According to the characteristics of the tea garden and the standard of high-quality tea shoots, a tea plucking servomechanism was designed in this study. The mechanism has three degrees of freedom and can move along the direction of the X, Y, and Z axis to localize the plucking points. The components of servomechanism mainly include a frame, a three-axis truss structure, and an end effector. The virtual prototype of the three-axis truss mechanism is established through ADAMS, and the kinematics simulation is analyzed to meet the feasibility of this mechanism. It presents that there is no interference and collision between components under working conditions. The material stress analysis is applied through the ANSYS workbench. It presents the plucking process and the stress on the tea stem. These results shorten the development time and provide the theoretical basis for manufacturing the tea-picking mechanism.
