This paper proposes a hierarchical model of the Tokay gecko's (Gekko gecko) setal system. Based on Euler's elastica theory, the inextensible fibrillar model of the seta is established, taking the thousands of terminating spatulae into account. The directional adhesion of the seta with different slanted angle of the adhesive pad and spatula pad is studied. The elastic energy and the binding energy...
The solving strategy of artificial intelligence (AI) is adopted with bottom-up design to solve its hard problems. To tackle end-to-end AI-hard problems, a highly self-adaptive control system-on-chip has been developed to self-learn its internal and external resources with the aid of sets of sensors and actuators. Inspired by biological cell learning theory, different approaches of modelling techniques...
In this paper, we present a biomechanical model capable of generating six-DoF trajectories of a swimming dolphin. Our model attempts to closely emulate an actual surfacing and diving dolphin. The degree of biomechanical complexity of our model stands as a reasonable compromise between a complicated flexible multi-link body and an overly-simplified pointmass. We constructed our model through analyzing...
Lower extremity exoskeletons can improve human strength and endurance with a pair of wearable robotic legs that support a payload. This paper summarizes the biomimetic design and biomechanical analysis of a novel 15-DOF (degree of freedom) lower extremity exoskeleton. The selection of the DOF, critical parameter design, and initial performance simulation are discussed. To provide a basis and guidance...
This paper presents a bio-inspired search behavior model for navigating using geomagnetic information in unknown environments. A multi-objective search navigation framework combining random walk movement model and stress evolution algorithm is applied to the navigation. Firstly, motivated by animal geomagnetic navigation behavior, we generalize the bio-inspired navigation process as the convergence...
With the mathematical theory of Yuanjian, this paper proposes a mathematical formulation of the secondary structure of nucleic acid The goal of this article is to represent and interpret the genetic structure at the molecular level mathematically, and to explore the fundamental principle of molecular biology and further research the disease mechanism at the system level. Propositions based on the...
Our bionic eye PTZ requires the tracking target at the central field of view of the camera, which means it is so important to realize the target tracking well in the first step. The particle filter method is famous for its robust tracking performance in cluttered environments. However, most methods are in the mode of moving object and stationary camera and they are not utilizing so well on the bionic...
Sir J. Lighthill mathematical slender body swimming model formulates the biological fish propulsion mechanism (undulation) in fluid environment. The present research has focused on the relevance of Lighthill (LH) based biomimetic robotic propulsion. A 2-joint, 3-link multibody vehicle model biologically inspired by a Body Caudal Fin (BCF) carangiform fish propulsion mechanism is designed. Different...
This paper aims to investigate the function of constant feed-forward control from the reticulospinal tract (RST) on improving posture stability during standing from the viewpoint of ability to countering the disturbances. We presented a stance control model considering not only the balance control, a PD controller, from vestibular tract based on vestibular feedback but also the constant feed-forward...
