This paper introduced a comparison method for three explicitly defined intermediate encoding methods in generative design two-dimensional soft robotic units. study evaluates conventional genetic algorithm with full access to removing elements from the domain using an implicit random layer, Lindenmayer system mimicking biological growth patterns and compositional pattern producing network 2D generation. The objective of optimisation problem is match deformation single actuator unit desired target shape, specifically uni-axial elongation, under internal pressure. results suggest that generates candidate units fewer function evaluations than traditional implicitly encoded algorithm. However, distribution constraint energy similar encoding, produces less diverse population In contrast, despite requiring more System Compositional Pattern Producing Network diversity Overall, proportionally higher number high-performing or making it viable alternative monolithic approach. may be promising approach designing actuators desirable performance characteristics.

Soft robots show compliance and have infinite degrees of freedom. Thanks to these properties, such can be leveraged for surgery, rehabilitation, biomimetics, unstructured environment exploring, industrial grippers. In this case, they attract scholars from a variety areas. However, nonlinearity hysteresis effects also bring burden robot modeling. Moreover, following their flexibility adaptation, soft control is more challenging than rigid control. order model robots, large number data-driven methods are utilized in pairs or separately. This review first briefly introduces two foundations approaches, which physical models the Jacobian matrix, then summarizes three kinds statistical method, neural network, reinforcement learning. compares modeling controller features, e.g., dynamics, data requirement, target task, within among categories.

Abstract Climbing robots have vital uses in uncharted terrain exploration, military intelligence collecting, and other areas. To address the drawbacks of classic wall-climbing robots, this study introduced a novel soft climbing robot constructed smart wood with switchable adhesion force. The experimental findings indicated that implemented research could effectively perform movements on diverse walls sloping pavements, enabled by temperature control through cold/hot water circulation pneumatic actuation. Further revealed reversible phase transition PNIPAM at different temperatures was main reason for variable force wood. Moreover, model developed work surface mostly composed contact mechanics capillary Finally, will offer insights design advance their potential applications.

Inspired by geckos, fibrillar microstructures hold great promise as controllable and reversible adhesives in the engineering field. However, enhancing adhesion strength stability of gecko-inspired (GIAs) under complex real-world contact conditions, such rough surfaces varying force fields, is crucial for its commercialization, yet further research lacking. Here, we propose a hierarchically designed GIA, which features silicone foam (SF) backing layer film-terminated microstructure subtle multiscale design. This structure has been proven to have "multiscale synergistic effect", allowing material maintain strong stable with changing normal pressures roughness. Specifically, high load, adhesive 2 times more than that conventional it 1.5 stronger on compared GIA.
