With the development and popularization of scientific breeding technology, the breeding of stichopus japonicus has formed industrialization gradually. In the process of seedling rearing, due to the death of individuals, the decay of feed and the excretion of juvenile stichopus japonicus, organic matter accumulation and decay were caused, which polluted the living environment of juvenile stichopus japonicus and led to the increase of the mortality of juvenile stichopus japonicus. Replacing the seedling pond has become the most important and effective way to improve water quality. The current tank changer for sea cucumber seedlings is divided into tray type tank changer and hook type tank changer, and the hook type tank changer is divided into bridge type tank changer and tower type tank changer. However, most of the existing tank changer adopts manual picking and hanging of net baskets, which is low in accuracy and efficiency. In this paper, a kind of the self-picking and hanging stichopus japonicus tank changer which can be automatically lifted is designed, which mainly includes the main frame and the lifting, moving, rebound hook and control modules. In order to reduce the manual input and improve the efficiency of unhook, a hook model which can be automatically unhook is designed by taking advantage of the stress and deformation characteristics of spring, and the force in the process of movement is analyzed and studied. The study of the springback hook model not only reduces the labor intensity, but also improves the efficiency of the tank.

According to the characteristics of sea cucumbers themselves, this paper designed a serial four-DOF sea cucumbers harvesting robot arm. The structure design of its end-effector is suitable for sea cucumbers to catch sea cucumbers in their living environment, Sashimi can be harvested from cracks in the rocks without damaging their structure. The threedimensional model of the machine upper limb is accepted by using Solid Works computer program. Using ANSYS to get the statics analysis of the large arm, and the simulation consequence indicates that the part strength encounters the requirements. The machine model was constructed in the simulation surroundings based on MATLAB platform and robot toolbox, and the Monte Carlo algorithm was used to get the 3d workspace scope of the mechanical arm, ensuring that the attachment area of sea cucumber in harvesting experiment was within the operating range of robot arm..The emulation test of path planning in the joint space exercised, and continuous and steady motion curve of the joint was gotten, which laid a theoretical foundation for the subsequent path planning control.
