The impressive agility of living systems seems to stem from modular sensing, actuation and communication capabilities, as well as intelligence embedded in the mechanics in the form of active compliance. As a step towards bridging the gap between man-made machines and their biological counterparts, we developed a class of soft mechanisms that can undergo(More)
This paper presents a new simulation method for flower blossom, which is based on a biological observation that flower opening is caused by a boundary-dominant morphological transition in a curved lamina. We use an elastic triangular mesh to represent a flower petal and adopt the in-plane expansion to induce the global bending. Out-of-plane curl plays an(More)
[1] We give an explanation for the polarity, localiza-tion, shape, size, and initiation of subduction zones on Earth. By considering a soft, thin, curved litho-spheric cap with either elastic or viscous rheology supported by a thick, nearly incompressible mantle, we find two different characteristic subduction geometries arise depending on boundary(More)
According to the characteristics of large rotating angle during the loading process for aircraft landing gear door, a four-bar linkage mechanical loading mechanism is designed. Considering the geometric structure, elastic deformation and quality, the four-bar linkage is established. To improve the dynamic accuracy of the system, a fuzzy fractional order PID(More)
An amphibious robot with straight compliant flipper-legs can conquer various amphibious environments. The robot can rotate its flipper-legs and utilize their large deflection to walk on rough terrain, and it can oscillate the straight flipper-legs to propel itself underwater. This paper focuses on the dynamics of the compliant straight flipper-legs during(More)
As an indispensible material for modern society, natural rubber possesses peerless mechanical properties such as strength and toughness over its artificial analogues, which remains a mystery. Intensive experimental and theoretical investigations have revealed the self-enhancement of natural rubber due to strain-induced crystallization. However a rigorous(More)
