This paper introduces a new snake robot with binary actuators and mainly focuses on the simulations of various snake gaits. Three categories of fitting algorithms are proposed. They are 1) Fitting Algorithm of One Module; 2) Position-Fitting Algorithm of Multiple Modules; 3) Configuration-Fitting Algorithm of Multiple Modules. All the fitting algorithms and their fitting results are elaborated in simulations of lateral undulation, one of the most widely used snake gaits. As the best fitting algorithm for lateral undulation, Configuration-Fitting Algorithm of Four Modules is also applied to a snake robot of different dimensions to demonstrate that it is a universal gait fitting algorithm for all kinds of snake robots with binary actuators.
