Abstract
It is well known that quadruped locomotion patterns are generated by central pattern generators (CPGs) residing within central nervous system interstitial cells. Based on this fact, many investigators have used CPG models to develop control adaptations in robots. Previously, the authors proposed a CPG model that generates and controls quadruped locomotion through single-pulse external inputs. However, in this model, a large capacitance was necessary for generating 1–10 Hz robot control patterns. In this paper, we suggest a CPG model in which swing and stance patterns produced by interstitial cells generate low-frequency patterns through a low-capacitance 0.18 μm CMOS process. It is demonstrated that this model method can generate five basic quadruped locomotion patterns (walk, pace, trot, bound, and gallop) at a frequency suitable for controlling a quadruped locomotion robot.
