Optimizing snake locomotion on an inclined plane.
We develop a model to study the locomotion of snakes on inclined planes. We determine numerically which snake motions are optimal for two retrograde traveling-wave body shapes, triangular and sinusoidal waves, across a wide range of frictional parameters and incline angles. In the regime of large transverse friction coefficients, we find power-law scalings for the optimal wave amplitudes and co...
متن کاملExperiments on the Influence of Snake-Poison
tary curves, but on being released it appeared unaffected. It was closely watched for some time, but showed no sign of being affected. It was as active and vicious as before, assuming an aggressive attitude, with its little hood erect, and striking vigorously at anything that approached it. It was bitten at 11-45 a.m., and I saw it again at 4 p.m.; it was then lively, but looked rather stiff, a...
متن کاملStability analysis of snake robot locomotion based on Poincaré maps
This paper presents an analysis of snake locomotion that explains how non-uniform viscous ground friction conditions enable snake robots to locomote forward on a planar surface. The explanation is based on a simple mapping from link velocities normal to the direction of motion into propulsive forces in the direction of motion. From this analysis, a controller for a snake robot is proposed. A Po...
متن کاملConsidering Snake Locomotion with “Continuum Legs”
1 Motivation Both legged and limbless animals often exhibit various types of locomotion by adapting to the current circumstances encountered in real time. This ability has been honed by evolutionary selection pressure, and there likely exists an ingenious mechanism that underlies any type of locomotion. Clarifying this mechanism will lead us to elucidate the fundamental principle of animal loco...
متن کاملDeformation-Based Animation of Snake Locomotion
We propose a fast and powerful method to create locomotive animation of a snake. The goal here is to provide an animator with highly familiar but greatly improved key-frame system that is efficient enough to expedite the animation process and flexible enough to accept creative input while achieving the striking visual realism required in movie production. These goals are achieved using a deform...
