A neural network with central pattern generators entrained by sensory feedback controls walking of a bipedal model.

abstract：:Randomness is common in biological and artificial systems, resulting either from stochasticity of the environment or noise in organisms or devices themselves. In locomotor control, randomness is typically considered a nuisance. For example, during dynamic walking, randomness in stochastic terrain leads to metastable d...
