外文摘要：To address the problems of high labor intensity, low efficiency of mobile operations, and insufficient feeding uniformity in high-level pond aquaculture, this paper proposes a trimaran unmanned feeding surface robot mechanism designed for high-level pond environments. The proposed robot adopts a modular trimaran configuration consisting of two lateral floats and a central working platform. Through the integrated design of buoyancy modules, load-bearing frames, and functional execution mechanisms, the proposed structure improves the robot's payload capacity, structural stability, and functional expandability. In addition, an automatic feeding mechanism integrating a conical hopper, vertical screw conveying mechanism, and centrifugal spreading mechanism is developed to achieve continuous transportation and wide-range distribution of granular feed. The load-bearing capability, stability, and motion performance of the robot mechanism are investigated through buoyancy analysis, initial stability evaluation, and hydrodynamic performance analysis. A prototype is fabricated to verify the engineering feasibility of the proposed structural design. The results indicate that the platform achieves an initial metacentric height of 0.693 m under the full-load condition, satisfying the static stability requirement. At the designed speed of 0.5 m / s, the navigation resistance is approximately 39 N, and the theoretical maximum speed can reach 0.81 m/s. These results demonstrate that the proposed trimaran unmanned feeding surface robot mechanism can satisfy the requirements of payload transportation and stable operation in high-level pond environments, providing a feasible engineering solution for mobile aquaculture robotic equipment design. ? 2026 IEEE.
