摘要

PURPOSE: A steering module and a bending module for stems, a stem system including the modules, and a plant robot including the stem system are provided to make various postures of stems through the five degree-of-freedom motion. CONSTITUTION: A bending module for stems comprises a stem support part(110), a cable part, and a driving part(130). The stem support part comprises a channel, a gear member(113), and a bearing member(112). The top of the cable part is fixed to the top of a stem part or the bottom of a bud part while the bottom is connected to the driving part through the stem support part. The driving part is composed of a bending unit(131) connected to the underside of the cable part, and a rotating unit(132) connected to the gear member.
