In this paper, we propose a new CPG model for the snake-like robot being able to adapt to different environments. This model can produce typical serpentine, sidewinding and traveling wave locomotion gaits and switch between them automatically based on a simple input signal. The stability of this model is verified and the parameter restrictions are determined. Then, we investigate the relationship...
With slim and legless body, particular ball articulation and rhythmic locomotion, a nature snake adapted itself to many terrains under the control of neuron system. Based on analyzing the locomotion mechanism, the main functional features of the motor system in snakes are specified in detail. Furthermore, a bidirectional cyclic inhibitory CPG model is firstly applied to imitate the pattern generation...
With 3D (3-dimensional) movement's ability and rhythmic locomotion mode, a nature snake makes itself survive in rugged terrains. The rhythmic activities of most creatures are generated by the CPG (central pattern generator). Based on this fact, the sustained-type neuron has been adopted to construct a cyclic inhibitory CPG model for a snake-like robot whose joints are perpendicularly connected in...
Snake-like robots that behaves biological snakes' characteristics have possibility to make them supremely adapted for environment. In this paper, we firstly design a snake-like robot controller with cyclic inhibitory CPG model, and then analyze the stability of single neuron, CPG model and the neuron oscillator network (NON). By implementing this control architecture to a simulator with consideration...
