The present application belongs to the technical field of flexible robots, and relates to a structure optimization method of a fin ray effect gripper, comprising the following steps: step 1: a co-rotation modeling method is used to construct a force-deformation relationship model of the fin ray effect gripper as a fast evaluation model of the performance of the gripper; step 2: structure optimization design parameters and multi-objective performance evaluation indexes of the fin ray effect gripper are determined; step 3: based on a Bayesian optimization algorithm, the fast evaluation model is combined to construct a multi-objective structure optimization framework, global optimal sample search is performed on the design parameters, and a Pareto front is solved; and step 4: experimental verification is performed on typical optimal parameter combinations in the Pareto front, and optimal structure parameters of the gripper suitable for different gripping scenes are output. The present application can be applied to the design and optimization of flexible, rigid and rigid-flexible hybrid robot compliant mechanisms, and can be widely applied to the high-performance design and parameter tuning of gripper structures in industrial gripping, service robots, precision operation and the like.

The application discloses an EHD printing integrated high-precision FPC antenna and a preparation method, and belongs to the technical field of FPC antennas, and comprises a substrate and a koch snowflake fractal radiation patch formed on the substrate; the metal line of the koch snowflake fractal radiation patch has an optimized nominal width W opt , and W opt is a parameter determined after a collaborative fault-tolerant design of the antenna structure, by modeling the line width manufacturing error of the EHD printing as a random variable within the range of ±15μm and taking the resonance frequency offset of the antenna not greater than 1.5% as an optimization target; the radiation patch is formed after being printed by conductive ink and undergoing synchronous ultraviolet pre-curing and stepwise thermal curing, and the conductive ink contains a load type Ag2O-MXene composite powder; through deep synergy and optimization of the structure fault-tolerant design, special functional materials and precise manufacturing processes, the application solves the mismatch problem in the process from a high-performance design model to high-fidelity physical antenna manufacturing, and especially provides a reliable integrated solution for flexible electronic manufacturing of complex micro-patterns.
