To address the problems relating to the low efficiency and high labor intensity of manual operation in transplanting potted flower plug seedlings, an automatic bowl-clamping-type transplanting mechanism with a planetary gear train based on incomplete non-circular gear transmission is proposed.The design of the mechanism combines forward parameter modification (guiding optimization design) and reverse design, providing a reference for solving practical problems in flower seedling transplanting.

Soft continuum manipulators show great promise in minimal invasive surgery (MIS) due to their excellent adaptability and contact safety. In our recent work,  a novel braided manipulator based on fibrous materials is developed which features a thin-walled structure and a linear actuation response, enhancing its suitability for surgical environments. This paper studies effects of design parameters on its kinematical behaviors, which can provide a foundation for an optimized skeleton design.

In this paper, a three-axis 6-degree-of-freedom ship stabilization platform is proposed and a fuzzy adaptive proportional–integral–derivative (PID) controller is designed. Comparison with the PID controller shows that the regulation time of PID and fuzzy PID is 7 s and 3.5 s, respectively.  The fuzzy adaptive PID controller has high tracking accuracy and stability. Finally, the control user interface of the ship stabilization platform is designed based on Qt Creator.

A deformable wheel mechanism with a single-degree-of-freedom drive is proposed for improved obstacle crossing in emergency operations. Its kinematics and performance, including its stiffness and expansion ratio, are analyzed and verified through simulations. A lightweight, stable resin prototype enhances expansion and stiffness, showing high adaptability and effectiveness for special vehicle wheels.
