Abstract:Unidirectionally coupled phase oscillators in a ring are simple structures but unsuitable for application in central pattern generators (CPGs) for six-legged walking due to coexisting stable synchronization patterns. This paper shows that the coupled oscillators can be applied to a CPG by utilizing a non-periodic signal generator as a clock. The nonperiodic clock-driven coupled oscillators are implemented by a sequential logic circuit using a field programmable gate array (FPGA) and a nonlinear analog circuit.… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
