In view of the complicated and unclean condition of lettuce harvesting, a lettuce leaf remover was designed, and the process of lettuce leaf removal and topology optimization were studied. A finite element model of defoliating knife-lettuce leaf cutting was established by Abaqus, and the variation rules of equivalent stress, cutting resistance, and cutting energy consumption were obtained. Based on the Memetic algorithm, the topology optimization model of the blade cutter is established by taking the maximum equivalent stress and tool volume as indexes, and the tool size and shape are optimized. Finally, the tool mass is reduced by 43%. The simulation results show that the cutting stress of the blade cutter decreases by 16.2%, and the displacement of the blade cutter decreases by 77.5%.

The traditional MPPT algorithms, such as the constant voltage method and perturbation observation method, are unable to track the maximum power point under non-uniform irradiance, which leads to the reduction of the efficiency of the PV system and becomes an important factor limiting the development of PV power generation technology, an improved conductance incremental method is proposed, and it is verified that the proposed method has a greater improvement in tracking stability compared to the conductance incremental method and the perturbation observation method, but it is also unable to deal with the multi-peak problem, so the improved conductance incremental method is combined with the cuckoo algorithm, and the actual position is firstly updated by the Levy flight module in the cuckoo algorithm, and after quickly finding the vicinity of the MPP point under multiple peaks of power, the algorithm is switched to the improved conductance incremental method for continuous tracking of the MPP.

A study was conducted on the variation law of the thermal error of the turntable during the shutdown state of a five-axis vertical horizontal conversion machining center, and the thermal error of the turntable was estimated based on the actual shutdown time; Then, the variation law of the thermal error of the rotary table with the cutting fluid spray time under the cutting fluid spray cooling state during hot engine was studied, and the shortest required cutting fluid spray time can be estimated based on different thermal errors; Then, a thermal error control model for the turntable was established, and the logic control optimization of the CNC (Computerized Numerical Control) system was carried out to achieve adaptive spraying control of cutting fluid. By significantly reducing the workload of turntable rotation accuracy detection, the cutting fluid spraying time has been more reasonably shortened, reducing the impact of turntable thermal errors on rotation accuracy and avoiding quality problems caused by turntable rotation accuracy not meeting requirements. By optimizing the PLC (Programmable Logic Controller) logic control program of the CNC system and calling the thermal spraying program, the automation level of the equipment has been improved and manual intervention has been reduced.

Underactuated robotic hands are low-cost, highly adaptive, and less damaging to objects during grasping. This paper proposes designing a flexible underactuated robotic hand based on tendon-driven mechanisms to enhance grasping stability. It establishes a D-H parameter model for single-finger kinematic analysis, simulates the workspace using MATLAB, combines inverse kinematic analysis with ADAMS for dynamic grasping simulation, and finally validates the hand’s feasibility through grasping-force analysis.

In order to solve the problems of insufficient trimming accuracy and poor adaptability of existing lawn mowers, as well as the status quo of large labor input cost and inconvenient operation, a lawn trimming device with a six-degree-of-freedom cutting device is proposed. In this paper, the structural design and static analysis of the device were investigated. First of all, the overall structure of the lawn mowing equipment is designed, the three-dimensional model of the equipment is established, and its working principle is analyzed. Secondly, the structural characteristics of the core mechanism of the equipment’s six-degree-of-freedom cutting device and suspension system are introduced in detail, and the unique advantages of this mechanism over traditional lawn mowing equipment are introduced. Finally, the key components were analyzed statically, and the results showed that the designed equipment meets the requirements for use. This study provides a new design idea for the research and development of lawn mowing equipment, which has certain practical reference value.

deeply analyzing the influence of ocean currents on the swimming mechanism of fish is of great significance to the study of bionic fish movement behavior. A bionic fish with a three-joint rudder driving the tail fin was chosen as the research object, the current speed and the swimming speed of the bionic fish were synthesized using the vector method, and the swinging of the fish body was controlled by the udf program of the dynamic mesh technology, and the swimming behaviors of the bionic fish were simulated using fluent software. Then, the force and vortex distribution of the bionic fish were investigated at different current sizes and different flow angles under the action of the ocean current. The simulation was carried out using fluent software to simulate the swimming behavior of the bionic fish. The calculation results provide a reference for reducing the influence of currents on the bionic fish and improving the propulsive efficiency and propulsive stability.
